Horiatiki Salad Recipe and The MIND Diet for Brain Health: More Benefits of Olive Oil

I’m a huge fan of both Greek and Middle Eastern salads, the ingredients of which are not only delicious but also mainstays of the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet, a way of eating designed for brain health. It’s an offshoot of the super-healthy Mediterranean diet and the DASH (Dietary Approaches to Stop Hypertension) diet. Why the distinction? Because the latest research on the MIND diet shows it can slow aging as well as reduce dementia risk. Add this to the list of the benefits of olive oil—it’s one of the super foods that MIND suggests including every day.

    The Simple Key to Resistance Training 

    Woman doing resistance training

    The first major update to resistance training recommendations in 17 years delivered a straightforward message: Even simple routines with small amounts of resistance training can improve strength, increase muscle size, enhance power, and support overall physical function. The key is not perfection but consistency.

    The updated guidance, released by the American College of Sports Medicine (ACSM) as a Position Stand and published in Medicine & Science in Sports & Exercise, is built on 137 systematic reviews covering more than 30,000 participants. This makes it the most extensive and evidence-based set of resistance training recommendations to date.

    “The best resistance training program is the one you’ll actually stick with,” said Stuart Phillips, PhD, distinguished professor in the department of kinesiology and an author on the Position Stand. “Training all major muscle groups at least twice a week matters far more than chasing the idea of a ‘perfect’ or complex training plan. Whether it’s barbells, bands, or bodyweight, consistency and effort drive results … The new document reflects that surge in evidence and expands its recommendations to include more people and more types of training than ever before.” 

    A key takeaway is that the biggest benefits often come from a simple starting point. Transitioning from no resistance training to any regular activity can lead to meaningful improvements. While factors such as load, volume, and frequency can be adjusted, experts say the main priority for most adults should be building a routine they can follow consistently.

    Another important shift in the recommendations is the recognition that effective resistance training does not require access to a gym. Exercises using elastic bands, bodyweight movements, or simple at-home routines can still produce measurable gains in strength, muscle size, and daily function.

    According to Dr. Phillips, strict rules about the “ideal” training plan are no longer supported by current evidence. Instead, personal preferences, enjoyment, and the ability to maintain a routine over time are what matter most. This approach is especially important for adults who want to stay strong, healthy, and capable as they age.

    Secret for a Happy Relationship

    Couples who intentionally pause to appreciate the enjoyable experiences they share tend to be more satisfied in their relationships, argue less, and feel more confident that their partnership will endure, according to researchers at the University of Illinois Urbana-Champaign. Soaking in their happy moments together—whether reminiscing about a favorite memory, enjoying a dinner together, or looking forward to something exciting—may be building a powerful shield for their relationship. 

    “Savoring involves slowing down to become aware of and focus on positive experiences,” said first author Noah Larsen, a graduate student at Illinois. “Savoring can occur when we reminisce on a past experience, focus on the present moment or look ahead to a future experience.”

    Previous studies have shown that savoring benefits individuals. Larsen and his colleagues, Illinois human development and family studies professors Allen W. Barton and Brian G. Ogolsky, wanted to see what happens when couples practice savoring together as a shared activity. The participants, drawn from a larger project examining resilience in romantic relationships, included 589 adults from across the United States who completed an online survey. The questionnaire measured how often they and their partners intentionally appreciated positive experiences in their relationship. Researchers used a scale called Joint Savoring in Romantic Relationships, adapted from the widely used Savoring Beliefs Inventory, which assesses how individuals savor positive moments.

    Participants also answered questions about how satisfied they felt with their spouse or significant other, how much conflict they experienced in communication, and how confident they were that their relationship would last. The survey assessed stress as well. Participants reported how frequently during the past month they felt in control of their responsibilities or, on the other hand, overwhelmed by what they had to handle. They also rated their overall quality of life, general health, and psychological distress.

    Of the 589 respondents, more than 85% were married, around 10% were engaged, and 4% were in committed dating relationships. Their partners did not participate in the survey. The average age was about 39. Slightly more than half were women, more than 85% were white, and the typical household income ranged from $85,000 to $95,000. Overall, participants reported relatively high levels of both individual savoring and joint savoring, along with generally low stress levels.

    “We found that joint savoring has the most benefits for romantic relationships, as well as secondary benefits for individuals’ health and well-being,” Larsen said. “Specifically, individuals who engaged in more joint savoring with their partners reported less conflict with them, more satisfaction with their relationship and more confidence in their future together.” The protective effect was especially noticeable among couples facing higher stress. “When couples face greater stress, savoring can serve as a buffer, helping protect their confidence in their relationship and their mental health,” Larsen said.

    One Simple Step Could Slash Depression Risk

    Swapping just an hour of TV a day for something more active could help prevent major depressive disorder. That is the conclusion of a new study published in European Psychiatry on behalf of the European Psychiatric Association by Cambridge University Press. Researchers found that the mental health benefits of reducing TV time were strongest for middle-aged adults, while the effects were smaller in younger and older groups. 

    The Dutch study tracked more than 65,000 adults over four years, with careful comparisons made across age groups. Individuals reported how much time they spent on activities such as active commuting, leisure exercise, sports, household tasks, physical activity at work or school, TV watching, and sleep. The researchers found that replacing 60 minutes of TV with other activities cut depression risk by 11% overall, and by nearly 19% in middle-aged adults. The more time people reallocated—up to two hours—the greater the benefit, with risk dropping as much as 43% in midlife.

    Lead author Rosa Palazuelos-González of the University of Groningen said the study stands out because it looked at what happens when TV time is actively replaced with other behaviors such as exercise or sleep. Previous research has largely examined links between sedentary lifestyles and depression, rather than analyzing how switching to specific alternative activities might influence the risk of developing the condition. Nearly all substitutions were linked to lower depression risk, with one exception. Swapping just 30 minutes of TV for household chores did not produce a meaningful change. However, reallocating 30 minutes to sports reduced risk by 18%. Replacing that time with physical activity at work or school lowered risk by 10.21%, leisure or commuting activities by 8%, and sleep by 9%. Across all time frames studied, sports delivered the greatest reduction in the probability of developing major depression.

  • Fennel and Orange Salad Fennel and Orange Salad

    My numerous trips to Italy to source fresh-pressed olive oil have led to my fondness for fennel, a cousin of celery with the taste of mild licorice, and a veggie totally underappreciated here. It’s the perfect complement for oranges—you’ll see them together in many dishes.

    Ingredients

    For the dressing:

    • 1 tablespoon orange zest from the navel orange (below)
    • 2 tablespoons freshly squeezed lemon juice
    • 1 tablespoon Dijon mustard
    • 1 teaspoon honey
    • 1/2 teaspoon coarse sea salt
    • 1/2 teaspoon freshly ground black pepper
    • 1/4 cup extra virgin olive oil

    For the salad:

    • 1 large or 2 small fennel bulbs
    • 1 navel orange
    • 2 blood oranges
    • 1 small red onion
    • 2 tablespoons chopped mint

    Directions

    Step 1

    Make the dressing: Zest the navel orange and add the zest to a large bowl with the lemon juice, mustard, honey, salt, and pepper. Whisk in the olive oil until well blended. Set aside.

    Step 2

    Prep the fennel: If you have a full bulb with the dill-like fronds, reserve a handful of fronds to chop and use as a garnish. Cut off the rest of the green stalks and the root end. Cut the bulb in two lengthwise, from the top to the root. Use a paring knife to carefully cut out the hard core at the base of each half. Then cut the fennel into thin slices as you would an onion and add to the bowl with the dressing. Toss well. 

    Step 3

    Score the oranges and peel off the rinds and as much of the pith as possible, then slice the oranges horizontally. Peel the onion and cut into thin rounds.

    Step 4

    To serve, arrange the orange and onion slices in a circular pattern on 2 plates or dishes. Top with equal amounts of the tossed fennel and garnish with chopped mint and reserved fennel fronds, if available.

    This elegant seafood recipe is a crowd pleaser and takes little time to prepare at home. It’s also an excellent source of lean protein. I’m sharing a study on how a unique mix of nutrients can quell systemic inflammation, showing the power of certain foods. Also, for anyone who’s worried about the effects of statins, a new research review found these cholesterol-busters don’t have many of the side effects they’ve been associated with.

    Canned Crab

    Unless you’re buying live crabs to cook yourself, crabmeat comes already cooked, even when it’s labeled fresh and hand-picked. It has a shorter shelf life than canned crabmeat, which is pasteurized. Both should be kept in the fridge. Whereas tub-packed fresh crabmeat should be eaten within a few days of purchase, pasteurized crabmeat will stay fresh in the fridge for up to 1 year, making it extremely versatile—it’s also typically less expensive. Once either is opened, it should be used right away.

    For Your Best Health 

    “Synbiotics” to Slash Inflammation

    A six-week study from the University of Nottingham suggests that pairing kefir with a diverse prebiotic fiber mix may deliver a powerful anti-inflammatory boost. This “synbiotic” combination outperformed omega-3 supplements and fiber alone, leading to the broadest drop in inflammation-related proteins in healthy adults. Participants in the synbiotic group showed lower overall inflammation levels, pointing to improved immune balance and a potentially reduced risk of chronic inflammation-related conditions, like heart disease or other metabolic conditions. The study was published in the Journal of Translational Medicine.

    The kefir and fiber blend used in the trial was supplied by Chuckling Goat Ltd. It contains a mix of naturally occurring probiotic bacteria and yeasts created during the traditional fermentation of goat’s milk with live kefir grains. These grains are living cultures that contain dozens of beneficial microbial species.

    When kefir, which is rich in live microbes, is paired with diverse prebiotic fiber, the result is a synbiotic effect. The fiber serves as fuel for the beneficial bacteria, allowing them to grow and generate helpful compounds such as butyrate, known for its anti-inflammatory and immune-regulating effects throughout the body.

    Future research will examine how these supplements perform in people who already have specific health conditions to better understand their potential benefits. “Our study shows that while all three dietary approaches reduced inflammation, the synbiotic had the most powerful and wide-ranging effects,” said lead author Dr. Amrita Vijay of the School of Medicine at Nottingham. “This suggests that the interaction between beneficial microbes and dietary fiber may be key to supporting immune balance and metabolic health.”

    Update on Statin Side Effects

    A large-scale review done by researchers at the University of Oxford found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo. Only a few side effects showed any link to statins, and even those were rare.

    Heart disease remains one of the leading causes of death worldwide, responsible for about 20 million deaths each year. Statins are widely prescribed medications that reduce LDL cholesterol and are proven to lower the risk of heart attacks, strokes, and other cardiovascular problems. Despite their strong track record, concerns about possible side effects have led some patients to hesitate or stop treatment.

    To better understand the true risks, researchers analyzed data from 23 major randomized studies conducted by the Cholesterol Treatment Trialists’ Collaboration. This included 123,940 participants in 19 trials comparing statins with a placebo, along with 30,724 participants in four trials that compared higher-intensity statin therapy with less intensive treatment.

    When the researchers reviewed reports of side effects, they found that people taking statins reported nearly the same rates of most symptoms as those taking a placebo. For instance, yearly reports of cognitive or memory problems were 0.2% among statin users and 0.2% among those on placebo. In other words, while some people may experience these symptoms during treatment, the evidence does not show that statins are the cause.

    The analysis found no meaningful excess of memory loss or dementia, depression, sleep problems, erectile dysfunction, weight gain, nausea, fatigue, headache, or many other commonly cited concerns. There was a small rise of about 0.1% in abnormal liver blood test results among people taking statins. However, this did not translate into higher rates of serious liver conditions such as hepatitis or liver failure. This suggests that these mild blood test changes typically do not lead to more severe liver disease. The researchers also found that statins can slightly raise blood sugar levels, meaning that individuals already at high risk for diabetes may develop the condition somewhat sooner.

    Earlier research from the same team showed that most muscle symptoms reported by patients were not caused by statins. Only about 1% of people experienced muscle symptoms attributable to statin therapy during the first year of use, with no additional excess risk after that. Christina Reith, associate professor at Oxford Population Health and lead author of the study, said, “Statins are life-saving drugs used by hundreds of millions of people over the past 30 years. However, concerns about the safety of statins have deterred many people who are at risk of severe disability or death from a heart attack or stroke. Our study provides reassurance that, for most people, the risk of side effects is greatly outweighed by the benefits of statins.”

    Asparagus Milanese Style Recipe, Spotlight on Asparagus, When to “Close” the Kitchen for the Night and Exercising to Avoid Alzheimer’s

    A sure sign of spring is the bundles of asparagus available at farmers’ markets and the produce aisle at your grocery store. I’m sharing a delicious way to enjoy them with a luscious one-pan prep. This issue’s research news offers food for thought: first, the advantages of not eating in the hours before bed for metabolic health and second, the benefits of exercise for brain health.

    Choosing Asparagus

    For decades, a debate has raged over what’s tastier, thin or thick asparagus. Surprisingly, according to agricultural experts at Penn State, spears that are larger than half an inch in diameter are more tender and higher in soluble fiber and vitamins than thinner spears. What’s more, marketing thin asparagus as “gourmet” stemmed from the fact that farmers wanted to sell their crops after two rather than three years to stimulate the plant to produce spears faster. At the same time, the shift prompted professional chefs to prefer the visual appeal of thinner spears. Of course, the most important factor is freshness—whichever you choose, look for tips that are tightly closed and stems that are not shriveled. Because asparagus loses moisture fast, aim to use it the day you buy it.

    Prepping Asparagus

    Many recipes call for a rack to be placed in the roasting pan to elevate a leg of lamb, turkey, or rib roast, to name a few examples. This allows the oven’s heat to reach (and brown) the entire surface of the food. Clean up can be made easier by first lining the roasting pan with foil, and the rack prevents the meat from touching the foil while it cooks. Putting about an inch of water in the bottom of the pan is done to create steam, which keeps the meat moist and prevents the drippings from burning and negatively affecting the taste of the meat.

    When to “Close” the Kitchen for the Night

    A simple shift in your evening routine may give your heart a measurable boost. Researchers at Northwestern Medicine explored whether timing an overnight fast to match a person’s natural sleep-wake cycle could improve heart and metabolic health. The circadian rhythm plays a central role in regulating cardiovascular and metabolic function. For the study, participants did not reduce calories. The focus was entirely on adjusting when they ate. 

    The scientists found that middle-aged and older adults at elevated risk for cardiometabolic disease benefited from extending their overnight fasting window by roughly two hours and avoiding food and dimming their lights for three hours before going to sleep. These changes led to measurable improvements in heart and metabolic markers during sleep and throughout the following day.

    “Timing our fasting window to work with the body’s natural wake-sleep rhythms can improve the coordination between the heart, metabolism, and sleep, all of which work together to protect cardiovascular health,” said first author Daniela Grimaldi, PhD, research associate professor of neurology in the division of sleep medicine at Northwestern University Feinberg School of Medicine.

    “It’s not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating,” said corresponding author Phyllis Zee, MD, PhD, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg.

    Time-restricted eating has grown in popularity because studies suggest it can improve cardiometabolic markers and sometimes match the benefits of traditional calorie-restricted diets. However, most research has concentrated on how long people fast rather than how well that fasting window aligns with sleep timing, which is crucial for metabolic regulation.

    With nearly 90% adherence in this trial, the researchers believe anchoring time-restricted eating to the sleep period may be a realistic and accessible non-pharmacological approach, especially for middle-aged and older adults who face higher cardiometabolic risk. The team plans to refine this protocol and expand testing in larger multicenter trials.

    Exercising to Avoid Alzheimer’s

    Researchers at UC San Francisco have identified a biological process that may explain why exercise sharpens thinking and memory. The discovery points to a surprising body-to-brain pathway that could inspire new Alzheimer’s disease therapies. 

    As people grow older, the blood-brain barrier becomes more fragile. This tightly packed network of blood vessels normally shields the brain from harmful substances circulating in the bloodstream. Over time, however, it can become leaky, allowing damaging compounds to enter brain tissue. The result is inflammation, which is linked to cognitive decline and is commonly seen in disorders such as Alzheimer’s disease.

    The researchers found that physical activity prompts the liver to release an enzyme called GPLD1. GPLD1 removes a harmful protein responsible for the blood-brain barrier becoming leaky with age, strengthening the brain’s built-in defense system, and helping protect it from age-related damage. Research using older mice showed that dialing down this protein reduced inflammation and improved memory. 

    This study builds on the research team’s early discovery that mice that exercised produced higher levels of GPLD1 in their livers. GPLD1 appeared to rejuvenate the brain, but there was a mystery. The enzyme itself cannot cross into the brain, leaving scientists unsure how it delivered its cognitive benefits. The new research provides an answer. It turns out that GPLD1 influences another protein known as TNAP. As mice age, TNAP builds up in the cells that form the blood-brain barrier. This buildup weakens the barrier and increases leakiness. When mice exercise and their livers release GPLD1 into the bloodstream, the enzyme travels to the blood vessels surrounding the brain and removes TNAP from the surface of those cells, helping restore the barrier’s integrity.

    “This discovery shows just how relevant the body is for understanding how the brain declines with age,” said Saul Villeda, PhD, associate director of the UCSF Bakar Aging Research Institute and senior author of the paper.

    The findings suggest that developing medications capable of trimming proteins such as TNAP could offer a new strategy to restore the blood-brain barrier, even after it has been weakened by aging. “We’re uncovering biology that Alzheimer’s research has largely overlooked,” Dr. Villeda said. “It may open new therapeutic possibilities beyond the traditional strategies that focus almost exclusively on the brain.”

  • Asparagus Milanese Style Asparagus in the Milanese Style

    Asparagus is so symbolic of spring. And while a simple dish like marinated asparagus is a great way to enjoy it, this recipe turns a side into a satisfying meal for breakfast, brunch, or even a light dinner. For a heartier meal, double the eggs. I especially love the richness of sautéing the spears in EVOO as well as some butter. 

    Ingredients

    • 4 tablespoons extra virgin olive oil, divided use, plus more for drizzling
    • 2 tablespoons unsalted butter
    • 1/2 pound asparagus, trimmed (see Quick Kitchen Nugget in newsletter)
    • Coarse sea salt
    • Freshly ground black pepper
    • 3/4 cup freshly grated Parmigiano-Reggiano cheese, plus more to garnish
    • 2 large eggs

    Directions

    Step 1

    Heat a large frying pan or skillet until hot, then add 2 tablespoons olive oil and the butter. Sauté the asparagus, rotating the spears frequently, until tender, about 5 minutes. Season liberally with salt and pepper. Cover the pan with a lid to steam them for 2 minutes more. Divide the spears between two plates and top with equal amounts of grated cheese.

    Step 2

    Reheat the pan to medium-high, then add the remaining 2 tablespoons olive oil. Once the oil starts to shimmer, add the eggs, one at a time, keeping them as separate as possible—you can crack them right into the pan or into a small bowl, then pour into the pan.

    Step 3

    Cook the eggs for 2 minutes until the whites turn opaque and develop crisp, brown edges. Use an offset spatula to center an egg over the asparagus on each plate. Spoon the olive oil from the pan over the top, drizzle with more olive oil, and sprinkle on more cheese as desired. Serve immediately.

Clean up can be made easier by first lining the roasting pan with foil, and the rack prevents the meat from touching the foil while it cooks. Putting about an inch of water in the bottom of the pan is done to create steam, which keeps the meat moist and prevents the drippings from burning and negatively affecting the taste of the meat.

    For Your Best Health: A New Opinion on Intermittent Fasting

    A New Opinion on Intermittent Fasting

    Over the past decade, numerous studies on intermittent fasting sparked new hope for people whose other weight-loss efforts weren’t as successful as desired. But a new major research review suggests the reality may not live up to the hype and that intermittent fasting does not produce significantly more weight loss than standard diet advice or even no structured plan at all. The findings challenge the widespread belief that changing when you eat leads to better weight-loss results than other approaches.

    The researchers examined data from 22 randomized clinical trials involving 1,995 adults in North America, Europe, China, Australia, and South America. The trials tested different fasting methods, including alternate-day fasting, periodic fasting, and time-restricted feeding. Most followed participants for up to one year.

    When compared with conventional diet advice or no intervention, intermittent fasting did not produce a clinically meaningful difference in weight loss. In practical terms, fasting schedules did not outperform more traditional guidance or doing nothing specific.

    Researchers also noted that side effects were not consistently reported across studies, making it difficult to fully assess potential risks. Since many of the trials examined were small and uneven in their reporting, the overall evidence base remains limited.

    “Intermittent fasting just doesn’t seem to work for overweight or obese adults trying to lose weight,” said Luis Garegnani, PhD, lead author of the review from the Universidad Hospital Italiano de Buenos Aires Cochrane Associate Centre. “Intermittent fasting may be a reasonable option for some people, but the current evidence doesn’t justify the enthusiasm we see on social media.”

    Another concern is the lack of long-term research. Few studies have examined how well intermittent fasting works over extended periods. “Obesity is a chronic condition. Short-term trials make it difficult to guide long-term decision-making for patients and clinicians,” Dr. Garegnani added.

    “With the current evidence available, it’s hard to make a general recommendation,” said Eva Madrid, the study’s senior author. “Doctors will need to take a case-by-case approach when advising an overweight adult on losing weight.”

    Understanding Nearsightedness Causes

    For years, the sharp rise in myopia, or nearsightedness, has largely been blamed on growing screen use, particularly among children and young adults. However, new research from scientists at the SUNY College of Optometry suggests the explanation may be more nuanced. Their study proposes that myopia may be influenced less by screens themselves and more by a common indoor behavior: extended close-up focusing in dim lighting, which reduces the amount of light reaching the retina.

    “Myopia has reached near-epidemic levels worldwide, yet we still don’t fully understand why,” said Jose-Manuel Alonso, MD, PhD, SUNY Distinguished Professor and senior author of the study. “Our findings suggest that a common underlying factor may be how much light reaches the retina during sustained near work, particularly indoors.”

    Myopia causes distant objects to appear blurry and has become increasingly common around the globe. It now affects nearly 50% of young adults in the United States and Europe and close to 90% in parts of East Asia. Although genetics contribute to risk, the rapid rise over just a few generations points strongly to environmental influences.

    Man reading screen in low light setting

    In laboratory research, myopia can be triggered in animal models through visual deprivation or the use of negative lenses, and these two methods are believed to involve different neuronal pathways. Doctors also slow myopia progression using multiple strategies that likely act through separate biological mechanisms such as multifocal lenses, ophthalmic atropine, contrast reduction, and promoting time outdoors. The researchers now suggest there may be a single neuronal explanation that connects these different methods of both inducing and controlling myopia.

    This new hypothesis attempts to solve a long-standing question in vision science: Why do such varied factors, from close-up work and dim indoor lighting to treatments like atropine drops, multifocal lenses, and increased time outdoors, all seem to affect how myopia progresses?

    “In bright outdoor light, the pupil constricts to protect the eye while still allowing ample light to reach the retina,” explained Urusha Maharjan, a SUNY Optometry doctoral student who conducted the study. “When people focus on close objects indoors, such as phones, tablets, or books, the pupil can also constrict, not because of brightness, but to sharpen the image. In dim lighting, this combination may significantly reduce retinal illumination.”

    Under this proposed mechanism, myopia may develop when insufficient light reaches the retina during sustained close-up work in low-light settings. If lighting is too dim and the pupil narrows excessively at short viewing distances, retinal activity may not be strong enough to support normal visual development. In contrast, exposure to bright light allows the pupil to constrict in response to brightness rather than focusing distance, helping maintain healthier retinal stimulation.

    The study also found that negative lenses decrease retinal illumination by causing the pupil to narrow through accommodation. This narrowing intensifies when viewing distance is shortened or when overly strong negative lenses are worn. It becomes even more pronounced when accommodation is sustained for prolonged periods of time and increases further once the eye has already become myopic. The researchers also observed additional disruptions in eye turning during accommodation and reduced effectiveness of eye blinks in triggering pupil constriction in myopic eyes. If validated, this proposed mechanism could significantly change how scientists and clinicians think about myopia progression. 

    “This is not a final answer,” Dr. Alonso emphasized. “But the study offers a testable hypothesis that reframes how visual habits, lighting, and eye focusing interact. It’s a hypothesis grounded in measurable physiology that brings together many pieces of existing evidence. More research is needed, but it gives us a new way to think about prevention and treatment.”

  • Roast leg of lamb with rosemary sprig Roasted Leg of Lamb

    If you have a butcher where you shop, ask them to prep the leg for you by removing the fell to skip this step. If not, follow the directions below. Overnight marination deepens the flavor of this traditional holiday meal. Serve with fresh spring vegetables and new potatoes.

    Ingredients

    • 1 bone-in leg of lamb, between 7 and 8 pounds 

    For the marinade:

    • 6 garlic cloves
    • 2 teaspoons coarse sea salt
    • 1 teaspoon freshly ground black pepper
    • 2 tablespoons whole grain Dijon mustard
    • 6 tablespoons extra virgin olive oil, plus more for the cooking rack
    • Juice of 1 lemon
    • 1 tablespoon fresh rosemary or 1 teaspoon dried rosemary needles 

    Directions

    Step 1

    Prep the lamb by removing the fell, the thin membrane overlaying the meat: Place the tip of a sharp thin knife under it at one end to lift it, then tug to pull it away. Trim most of the visible fat but leave a very thin layer in place—this adds to the flavor of the cooked meat. Next, use a paring knife to make uniform 1/2” slits in the meaty parts of the leg. Transfer to a platter.

    Step 2

    Mince the garlic cloves in a mini chopper, then add the rest of the ingredients and process until smooth. Slather the mixture on the lamb, working it into the slits. Tightly cover the leg with parchment paper, place in a plastic bag, and refrigerate overnight.

    Step 3

    Set your oven to 400°F. For easy cleanup, line your roasting pan with foil. Place a V-shaped rack in the pan and brush it lightly with olive oil. Place the lamb on the rack, then fill the bottom of the pan with 1/4” water. Place in the oven and roast for 15 minutes. Without opening the oven door, reduce the temperature to 350°F. Continue roasting until an instant-read thermometer inserted in the meatiest part of the leg reaches between 130°F and 135°F, about 20 minutes per pound of lamb.

    Step 4

    Out of the oven, let the lamb rest for 15 minutes before slicing.

The MIND Diet for Brain Health: More Benefits of Olive Oil

According to a new study from researchers at the Columbia University Mailman School of Public Health and The Robert Butler Columbia Aging Center, a very specific brain-boosting diet has been linked to reduced dementia risk and a slower pace of aging. The study, “Diet, Pace of Biological Aging, and Risk of Dementia in the Framingham Heart Study,” published in the Annals of Neurology, also explains how the diet helps slow down the processes of biological aging.

“Much attention to nutrition in dementia research focuses on the way specific nutrients affect the brain,” said Daniel Belsky, PhD, associate professor of epidemiology and a senior author of the study. “We tested the hypothesis that healthy diet protects against dementia by slowing down the body’s overall pace of biological aging.”

The researchers used data from the second generation of the Framingham Heart Study, the Offspring Cohort. Participants were 60 years of age or older and free of dementia and had available dietary, epigenetic, and follow-up data. Follow-up was done at nine examinations, approximately every 4 to 7 years, which included a physical exam, lifestyle-related questionnaires, blood sampling, and, starting in 1991, neurocognitive testing. Of 1,644 participants included in the analyses, 140 developed dementia. 

To measure the pace of aging, the researchers used an epigenetic clock called DunedinPACE developed by Dr. Belsky and colleagues at Duke University and the University of Otago in Dunedin, New Zealand. The clock measures how fast a person’s body is deteriorating as they grow older, “like a speedometer for the biological processes of aging,” explained Dr. Belsky.

“We have some strong evidence that a healthy diet can protect against dementia,” said Yian Gu, PhD, associate professor of neurological sciences at Columbia University Irving Medical Center and the other senior author of the study, “but the mechanism of this protection is not well understood.” Past research linked both diet and dementia risk to an accelerated pace of biological aging. “Testing the hypothesis that multi-system biological aging is a mechanism of underlying diet-dementia associations was the logical next step,” explained Dr. Belsky.

The research determined that higher adherence to the MIND diet slowed the pace of aging as measured by DunedinPACE and reduced risks for dementia and mortality. Furthermore, slower DunedinPACE accounted for 27% of the diet-dementia association and 57% of the diet-mortality association.

“Our findings suggest that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention,” said first author Aline Thomas, PhD, of the Columbia Department of Neurology and Taub Institute for Research on Alzheimer’s Disease and the Aging Brain. “However, a portion of the diet-dementia association remains unexplained, therefore we believe that continued investigation of brain-specific mechanisms in well-designed mediation studies is warranted.”

“We suggest that additional observational studies be conducted to investigate direct associations of nutrients with brain aging, and if our observations are also confirmed in more diverse populations, monitoring biological aging may indeed inform dementia prevention,” noted Dr. Belsky.

Exactly What Is the MIND Diet?

MIND is a hybrid of the Mediterranean and DASH diets, tailored to reflect key findings from nutrition and dementia research. It details serving sizes of specific foods to focus on and which to limit, primarily those high in saturated fat, which is known to negatively affect brain health. 

Foods and portions to eat every day: 1/2 to 1 cup green leafy vegetables, 1/2 cup other vegetables, 2 tablespoons extra virgin olive oil, and three 1-ounce servings of whole grains. 

Foods and portions to eat over the course of each week: 5 ounces nuts, 2-1/2 cups berries, 1-1/2 cups legumes, two 3-to-5-ounce servings of skinless poultry, and 3-to-5 ounces fish.

Foods to limit to these weekly totals: three or fewer 3-to-5-ounce servings of red and processed meats, 1 ounce whole-fat cheese, 1 fried or fast food, and 4 sweet servings. If desired, no more than 1 teaspoon of butter or stick of margarine a day.

Elevated Grilled Cheese Sammies Recipe, Spotlight on Arugula, Avocado and Cast Iron Skillets, and How to Manage Chronic Pain with Exercise

Comfort foods are oh so yummy but often don’t have the best health profile. My version of the classic grilled cheese packs high-nutrient foods that deliver on taste, too. One of them is avocado, a food that’s not only good for you on its own but also seems to encourage healthier eating in general, according to a study I’m sharing. You’ll also read about a healthy therapy to help forestall or ease chronic pain. 

Elevated Grilled Cheese Sammies

  • Gourmet Grilled Cheese Sandwich Elevated Grilled Cheese Sammies

    Even finicky eaters rush to the kitchen when grilled cheese sandwiches are on the menu. With a few ingredient upgrades, this lunch or dinner mainstay tastes even more delicious.

    Ingredients

    • Extra virgin olive oil, as needed
    • 2 ounces Manchego cheese, shredded
    • 1 ripe avocado, cut into thin slices
    • 1 ripe pear, cut into thin slices
    • 1 tablespoon fig jam
    • 1-2 cups arugula
    • 4 thin slices crusty whole wheat bread

    Directions

    Step 1

    Brush one side of each slice of bread with olive oil. Build the sandwiches on two of the slices, layering the ingredients equally in this order: a sprinkling of cheese, avocado slices, pear slices, fig jam, arugula, the rest of the cheese, and the top slice of bread. 

    Step 2

    If using a panini press, brush the outsides of the bread with olive oil and heat the press and grill the sandwiches as directed. If using a griddle, heat over medium heat; when hot, add two tablespoons of olive oil in two separate pools and place a sandwich over each pool. Press down on the sandwiches with a large spatula or an empty cast iron skillet (see “Quick Kitchen Nugget” below). When the bottoms have browned, flip the sandwiches and repeat.

Healthy Ingredient Spotlight: Amazing Arugula

Healthy Ingredient Spotlight

Amazing Arugula

Arugula, pear and manchego salad

We often talk about sensing the spiciness of arugula when doing our fresh-pressed olive oil tastings—the tender greens are full of zesty flavor. If arugula isn’t already on your shopping list, it’s time to add it. The cool weather of spring and fall is its ideal growing environment. Young, or “baby,” arugula is milder in taste—though still peppery—than more mature or late-season harvests.

Though often found in bagged lettuce mixes, arugula (Eruca vesicaria) is actually a cruciferous vegetable, part of the same family as broccoli, cabbage, and kale—and just as packed with nutrients, including antioxidants. In addition to vitamins A, C, K, and folate and the minerals calcium, iron, potassium, and magnesium, arugula has glucosinolates, natural substances that offer some protection from certain types of cancer, such as cancers of the breast, prostate, colon, and lung (glucosinolates are also responsible for that spicy bitterness). 

Arugula makes a great addition to hot and cold sandwiches, focaccia, and pizzas—just be sure to add it after your pizza is cooked, or the high temperature of the oven will burn it quickly. 

Baby arugula tends to come prerinsed, but when growing your own or buying a bunch from the greengrocer, just before eating submerge the leaves in a large bowl of cool water and agitate them to remove any dirt. Wait two minutes, then scoop out the leaves with a spoon strainer, pat dry, and enjoy.

Cast Iron Skillet: A Makeshift Panini Press

The value of a panini press is that it grills both sides of a sandwich at once and compacts the contents for better cheesy goodness. But you can achieve a similar effect by placing a cast-iron skillet on top of your sandwich on a griddle or grill. You’ll still have to flip the sandwich, but the skillet’s weight will compress it as it toasts on each side. If you use this method, don’t brush the top outer piece of bread with oil until you’re ready to flip it, to keep the oil from transferring to the skillet. 

For Your Best Health: An Avocado a Day…

For Your Best Health

An Avocado a Day…

A group of researchers from Wake Forest University School of Medicine, Tufts University, the David Geffen School of Medicine at the University of California Los Angeles, Loma Linda University, and Penn State University examined how the food-based intervention of eating one nutrient-dense avocado per day could impact overall diet quality. Surprisingly, only 2% of American adults eat avocados on a regular basis, even though they’re high in fiber and healthy fats, among many other nutrients. The study was published in the journal Current Developments in Nutrition  

“Previous observational research suggests avocado consumers have higher diet quality than non-consumers. So, we developed this study to determine if there is a causational link between avocado consumption and overall diet quality,” said Kristina S. Petersen, PhD, associate professor of nutritional sciences at Penn State. 

For the research, 1,008 participants were split into two groups. One group continued their usual diet and limited their avocado intake during the 26-week study, while the other group incorporated one avocado per day into their diet.

Researchers conducted phone interviews with participants before the study began and at a few points throughout to determine what their dietary intake was like in the previous 24 hours and evaluated their diets using the Healthy Eating Index to see how well they adhered to the Dietary Guidelines for Americans, which was used as a measure of overall diet quality.

“We found that the participants who had an avocado per day significantly increased their adherence to dietary guidelines,” Dr. Petersen said. “By improving people’s adherence to dietary guidelines, we can help to reduce their risk of developing chronic conditions and prolong healthy life expectancy.…In our study, we classified avocados as a vegetable and did see an increase in vegetable consumption attributed to the avocado intake, but also participants used the avocados to replace some unhealthier options…as a substitute for some foods higher in refined grains and sodium.”

Dr. Petersen has conducted similar studies investigating the impact of food-based interventions, including the relationship between pistachios and diet quality. She added that more research is needed to determine what other food-based strategies and behavioral strategies could also be used to improve adherence to dietary guidelines.

Physical Activity for Chronic Pain Protection

Researchers from UiT The Arctic University of Norway, the University Hospital of North Norway (UNN), and the Norwegian Institute of Public Health knew from an earlier study of  more than 10,000 adults that those who were physically active had a higher pain tolerance than those who were sedentary—and the higher the activity level, the higher the pain tolerance. They next wanted to understand how physical activity could affect the chances of experiencing chronic pain years later and whether this is related to how physical activity affects our ability to tolerate pain. So, they embarked on new research involving almost 7,000 people recruited from the large Tromsø survey, the Norwegian database that has collected data on people’s health and lifestyle over decades.

They obtained information about the participants’ exercise habits during their free time and whether they experienced pain that lasted for 3 months or more, including widespread or severe pain. 

“We found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later,” said doctoral fellow Anders Årnes at UiT and UNN, one of the researchers behind the study. He adds that for severe chronic pain in several places in the body, higher activity was associated with a 16% reduced risk.

Exercise to manage chronic pain

The researchers found that the ability to tolerate pain played a role in this apparent protective effect. “This suggests that physical activity increases our ability to tolerate pain and may be one of the ways in which activity helps to reduce the risk of severe chronic pain,” said Årnes.

When it comes to exercising if you already have chronic pain, the researcher said: “Physical activity is not dangerous in the first place, but people with chronic pain can benefit greatly from having an exercise program adapted to help them balance their effort so that it is not too much or too little. Healthcare professionals experienced in treating chronic pain conditions can often help with this. A rule of thumb is that there should be no worsening that persists over an extended period, but that certain reactions in the time after training can be expected.”

The research, “Does pain tolerance mediate the effect of physical activity on chronic pain in the general population? The Tromsø Study,” was published in the journal Pain.

Iced Blueberry Scones Recipe, Spotlight on Blueberries and Bench Scrapers, Managing Depression with Scents, and Resistance Training for Anxiety

May is Mental Health Awareness Month, first established in 1949 to increase our understanding of the vital role mental health plays in overall health and well-being and to celebrate recovery from mental illness. With all the stresses of daily living we face today, addressing mental health has never been as important. So, in addition to my recipe for scones, I’m including two different advances in mental health care that could impact how depression and anxiety are managed.

Iced Blueberry Scones

  • Iced Blueberry Scones Iced Blueberry Scones

    If you’ve ever had a store-bought scone, chances are it was dry and crumbly. My recipe is flaky yet still tender, thanks to the olive oil in the pastry flour dough. A light icing drizzle balances out the tartness of blueberries. 

    Ingredients

    For the Scones:

    • 2 cups pastry flour, plus more for the cookie sheet and shaping the dough
    • 1/4 cups whole wheat pastry flour 
    • 1/3 cup sugar
    • 1 tablespoon baking powder
    • 1 teaspoon coarse sea salt
    • 1/2 cup extra virgin olive oil
    • 2/3 cup half-and-half
    • 1 extra-large egg
    • 1 teaspoon vanilla 
    • 1 cup fresh blueberries, rinsed and patted dry

    For the Glaze:

    • 1 cup confectioners’ sugar
    • 1 tablespoon freshly squeezed lemon juice

    Directions

    Step 1

    Preheat your oven to 400°F. Line a cookie sheet with parchment paper and sprinkle it liberally with flour.

    Step 2

    Place the 2-1/4 cups flour (pastry and whole wheat), sugar, baking powder, and salt in a mixing bowl and whisk to combine. In a separate bowl, thoroughly whisk the olive oil, half-and-half, egg, and vanilla. Using a large spatula, fold in the blueberries and then the flour mixture. Be careful not to overmix, which can cause too much gluten development and a dense scone.

    Step 3

    Turn the dough out onto the parchment paper. Heavily flour your hands and use them to pat the dough into a 12-by-8-inch rectangle (do not use a rolling pin). If the dough is extremely wet, sprinkle on a tablespoon of additional flour. Use a bench scraper to help even out the edges, cut the dough into 12 triangles or squares, and then move the pieces as needed to leave about two inches between them.

    Step 4

    While the scones are cooling, mix the confectioner’s sugar and lemon juice, thinning if needed with 1 tablespoon of water. Use a spoon to drizzle on the icing in a crisscross pattern.

    Step 5

    Serve warm or at room temperature. Store any leftovers in the fridge.

Healthy Ingredient Spotlight: Frozen Blueberries

Healthy Ingredient Spotlight

Frozen Blueberries

Blueberries are more than delicious—they’re at the top of many healthiest-foods lists because of their amazing nutrients. Along with vitamins C and K and the mineral manganese, they’re rich in anthocyanins, which give them their blue-purple color and protect cells from damaging molecules called free radicals. Their soluble fiber helps lower blood sugar, manage blood pressure, and sweep out cholesterol, which, in turn, can lower the risk for heart disease. 

Spring is the start of blueberry season, but when fresh ones aren’t available, frozen ones make a great stand-in (it’s also smart to freeze fresh berries you grow or buy throughout the summer so that you’ll have them for next fall and winter). Bakers are often disappointed by the bleeding frozen berries can cause, creating streaks of purple or even green in the finished baked goods. This doesn’t affect taste, but here’s a quick hack to avoid it: Just before adding them to your batter, rinse the frozen berries well in cold water and then thoroughly pat them dry between layers of paper towels. Quickly fold them into the batter using just a few strokes. Keep in mind that you are rinsing away some of the berries’ healthful anthocyanins, so if the streaks don’t bother you, simply pat defrosted berries with paper towels before adding them to the batter to avoid adding excess moisture.

The Value of a Bench Scraper

This lightweight tool, designed to help you move dough when working on a countertop or “bench,” does more than its name indicates. Press the side against your dough to even its sides—this may eliminate the need for trimming the edges. Use the edge of the scraper to cut dough into scones, biscuits, bar cookies, or crackers. Also, the flat side works like a metal spatula to transfer dough pieces to your baking sheet. Available at most housewares stores and online, a good stainless steel bench scraper runs $10-$15.

Managing Depression: Using Scents to Unlock Memories 

A study done by University of Pittsburgh School of Medicine researchers and University of Pittsburgh Medical Center social workers and published in JAMA Network Open has found that scents are more effective than words at calling up a memory of a specific event. Scents could even be used to help people experiencing depression get out of negative thought cycles and rewire thought patterns, aiding faster and smoother healing.

Early in her career, Kymberly Young, PhD, a neuroscience researcher who studies autobiographical memories, realized that engaging the amygdala, the part of the brain that not only controls the fight-or-flight response but also directs attention and focus to important events, helps with memory recall. 

She also knew of extensive evidence that people with depression have a hard time recalling specific autobiographical memories and that, in healthy individuals, odors trigger memories that feel vivid and real, likely because they directly engage the amygdala through nerve connections from the olfactory bulb.

“It was surprising to me that nobody thought to look at memory recall in depressed individuals using odor cues before,” said Dr. Young, senior author of the study and associate professor of psychiatry at Pitt. So, she decided to test whether engaging the amygdala could help depressed individuals access their memories more effectively. 

Rather than start with brain scanner tests, she decided to go low tech, presenting study participants with a series of opaque glass vials containing potent familiar scents including everything from oranges and ground coffee to shoe polish and even Vicks VapoRub.

After asking participants to smell a vial, Dr. Young asked them to recall a specific memory, good or bad. She was surprised to discover that memory recall was stronger in depressed individuals who received odor cues as opposed to word cues. Also, those who received odor cues were more likely to recall a memory of a specific event (for example, that they went to a coffee shop the previous Friday) than general memories (that they have been to coffee shops before). Memories spurred by odors were also a lot more vivid and felt more immersive. Even though Dr. Young did not direct participants to specifically recall positive memories, her results found that positive memories were more likely to be recalled.

Dr. Young will soon start more technologically advanced studies using a brain scanner, but she is excited about the progress already made. “If we improve memory, we can improve problem-solving, emotion regulation, and other functional problems that depressed individuals often experience,” she said.

Resistance Training for Anxiety

Researchers Matthew P. Herring, PhD, of the University of Limerick (UL) in Ireland, and Jacob D. Meyer, PhD, of Iowa State University (ISU), recently published an article in the journal Trends in Molecular Medicine to review evidence supporting the positive effects that resistance exercise training can have on anxiety and depression.  

“There is a critical need for confirmatory, definitive trials that adequately address limitations [of existing research], but the limited evidence available to us provides initial support for the beneficial effects of resistance exercise training on these mental health outcomes, including increased insulin-like growth factor 1, cerebrovascular adaptations, and potential neural adaptations influenced by controlled breathing inherent to resistance exercise,” explained Dr. Herring, associate professor in the Physical Activity for Health Research Centre, Health Research Institute, and department of physical education and sport sciences within the faculty of education and health sciences at UL, and a fellow of the American College of Sports Medicine. 

Resistance training/exercise

“Notwithstanding the limitations of the limited number of studies to date, there is exciting evidence, particularly from our previous and ongoing research of the available studies, that suggests that resistance exercise training may be an accessible alternative therapy to improve anxiety and depression. Anxiety and depressive symptoms and disorders are prevalent and debilitating public health burdens for which successful treatment is limited,” Dr. Herring said. “A more exciting aspect is that there is substantial promise in investigating the unknown mechanisms that may underlie these benefits to move us closer to maximizing benefits and to optimizing the prescription of resistance exercise via precision medicine approaches.” 

“The current research provides a foundation for testing if resistance training can be a key behavioral treatment approach for depression and anxiety,” said Dr. Meyer, an expert on the neurobiological effects of exercise on depression and director of ISU’s Wellbeing and Exercise Laboratory, focused on understanding how exercise and sedentary activities are related to mental health and well-being. “As resistance training likely works through both shared and distinct mechanisms to achieve its positive mood effects compared to aerobic exercise, it has the potential to be used in conjunction with aerobic exercise or as a stand-alone therapy for these debilitating conditions. Our research will use the platform established by current research as a springboard to comprehensively evaluate these potential benefits of resistance exercise in clinical populations while also identifying who would be the most likely to benefit from resistance exercise.”

Composed Salad with Apple Balsamic Vinaigrette Recipe, Spotlight on Salad Greens, A Monthly 5-day Modified Fast to Boost Longevity and A Surprising Advantage of Exercise 

Composed salad—only the name of this dish sounds tricky. It’s actually a simple technique to arrange ingredients in a beautiful display and let everyone pick and choose what to put on their own plate. I’ve provided suggestions, but you get to pick your culinary adventure! 

Club members know that I believe in nourishing the body with healthful foods (that’s why sourcing fresh-pressed olive oil brimming with polyphenols is so important to me!). And in turn, the body can enrich us in remarkable ways. Two studies provide astounding food for thought to prove that point. The first is a new approach to intermittent fasting, and the second shows how bookmarking learning something new with bouts of physical exercise can help you retain the new information. Enjoy these fascinating reads.

Composed Salad with Apple Balsamic Vinaigrette

  • Composed Salad Composed Salad with Apple Balsamic Vinaigrette

    Sounds complicated and even more exotic in its original French—“salade composée”—but a composed salad is nothing more than an artful way to arrange your ingredients rather than tossing them together. Salade Niçoise and Cobb salad are two that are typically presented this way, but a composed salad can be made of any ingredients you choose—and it’s a great way to showcase fresh seasonal vegetables and even fruits. The following ingredients and directions are merely guidelines—let your imagination be your guide and remember that unusual combos can be delicious. Whatever you choose should have a flavorful dressing, so I’m including the recipe for one of my favorite vinaigrettes. It uses apple balsamic vinegar, a great change from classic balsamic of Modena.

    Ingredients

    For the vinaigrette:

    • 1⁄4 cup Apple Balsamic Vinegar
    • 1⁄4 teaspoon dried basil leaves, crushed 
    • 1 small shallot, minced 
    • 1 garlic clove, minced 
    • Pinch red pepper flakes
    • 1⁄2 cup extra virgin olive oil
    • Coarse salt and freshly ground black pepper to taste

    For the platter, choose any combination:

    • Protein: pick 1 or 2, such as sliced chicken, hard-boiled egg halves, or strips of prosciutto
    • Cheese: pick 1 or 2 such as cubes of fresh mozzarella or aged Parmigiano-Reggiano, or thin rounds of goat cheese
    • Greens: pick 1 lettuce or another leafy green, like arugula or baby spinach
    • Vegetables: pick 3 or 4, raw, steamed, or grilled, such as asparagus, cherry tomatoes, and string beans
    • Fruit and nuts: pick 1 or more, such as grapes, apple or pear slices, raisins or another dried fruit, avocado, and almonds or walnuts 
    • Legumes: pick 1, such as cooked beans or chickpeas

    Directions

    Step 1

    Make the vinaigrette: In a medium mixing bowl, whisk together the vinegar, basil, shallot, garlic, and red pepper flakes. Gradually whisk in the olive oil until the dressing is emulsified. Season to taste with salt and pepper.

    Step 2

    Compose your salad: Rinse and pat dry all raw ingredients. Cut all ingredients into bite-size pieces or thin slices. Lettuces and other greens can be sliced into ribbons. Choose a large platter and place one ingredient at a time, going from left to right. 

    Step 3

    Place the vinaigrette on the side so each person can add as much or as little as they want.

Healthy Ingredient Spotlight: Salad Greens

Salad Greens 

I’m a fan of varying the greens in my salads rather than sticking to one type every time. This choice goes beyond taste—each green has a different nutrient profile, so mixing it up means you get a wider range of vitamins, minerals, and other phytochemicals. Here are some choices to put in your own personal rotation.

Iceberg is one of the few lettuces that comes in a very compact head; another is romaine. The leaves of the more delicate butterhead and Boston lettuces are more loosely held together. Red or green loose-leaf lettuce and escarole aren’t compact at all.  

Many greens are sold as leaves, bundled or loose, including watercress, Swiss chard, arugula, baby spinach, and dandelion greens. Some leaves, like kale, have rigid spines or stems that you might want to remove if eating raw but that soften when cooked. 

All greens are a good source of fiber and water. Romaine and spinach have the highest amounts of vitamin A and folate (a B vitamin), spinach and Swiss chard are highest in vitamin K and potassium, and kale and spinach take top honors for calcium.

It’s frustrating to buy a box or package of greens—or even a loose head—only to find that some of the leaves have turned when you go to make a salad. These quick tips can help keep them fresh.

If possible, store greens by themselves (and definitely away from any fruit) in one of the crisper drawers of your fridge with the humidity set at high. Newer, more high-tech refrigerators offer very precise climate control, sometimes through an app on your phone.  

If your greens are bagged, you can try the puffing technique: blow into the bag to puff it up (like a balloon) and then seal in the air by closing the bag with a rubber band. Another option, especially if your greens are in a plastic clamshell or tight bag, is to spread them out in single layers between sheets of paper towels (discard any leaves that have wilted), roll up the paper towels, and store the roll in a reusable container. Rinse before eating, not before storing.

For Your Best Health: A Monthly 5-day Modified Fast to Boost Longevity

A Monthly 5-day Modified Fast to Boost Longevity

We’ve shared reports of studies showing that you may be able to reduce inflammation and better ward off diseases with intermittent fasting—eating fewer than 500 calories on two days of every week or limiting eating to an 8- or 10-hour daily window. Recently, a University of Southern California Leonard Davis School of Gerontology-led study, published in the journal Nature Communications, found that one five-day monthly cycle of a diet that mimics fasting, known as a fasting-mimicking diet (FMD), can reduce signs of immune system aging, as well as insulin resistance and liver fat, resulting in a lower “biological” age—a measure of how well your cells and tissues are functioning regardless of your chronological age.

The FMD, developed by Valter Longo, PhD, the study’s senior author and professor at the USC Leonard Davis School, is high in unsaturated fats and low in overall calories, protein, and carbohydrates. It’s designed to mimic the effects of a water-only fast while still providing necessary nutrients and making it much easier for people to complete. 

“This is the first study to show that a food-based intervention that does not require chronic dietary or other lifestyle changes can make people biologically younger, based both on changes in risk factors for aging and disease and on a validated method developed by the Levine group to assess biological age,” Dr. Longo said. (The Levine group, led by Morgan Levine, PhD, designs tools just to measure biological age.) 

Previous research led by Longo indicated that brief, periodic FMD cycles are associated with a range of beneficial effects, such as promoting stem cell regeneration, easing chemotherapy side effects, and reducing the signs of dementia in mice. Dr. Longo’s lab also had previously shown that one or two cycles of the FMD for five days a month increased the health span and lifespan of mice on either a normal or a Western diet, but the effects of the FMD on aging and biological age, liver fat, and immune system aging in humans were unknown until now. In addition, the FMD cycles can lower the risk factors for cancer, diabetes, heart disease, and other age-related diseases in people.

The study analyzed the diet’s effects in two clinical trial populations, each with men and women between the ages of 18 and 70. Patients who were randomized to the fasting-mimicking diet underwent 3-4 monthly cycles, adhering to the FMD for 5 days, then ate a normal diet for 25 days. The FMD is comprised of plant-based soups, energy bars, energy drinks, chip snacks, and tea plus a supplement providing high levels of minerals, vitamins, and essential fatty acids. 

An analysis of blood samples from trial participants showed that those in the FMD group had lower diabetes risk factors, including less insulin resistance and lower HbA1c results. Magnetic resonance imaging also revealed a decrease in abdominal fat as well as fat within the liver, improvements associated with a reduced risk of metabolic syndrome. In addition, the FMD cycles appeared to increase the lymphoid-to-myeloid ratio, an indicator of a more youthful immune system. Further statistical analysis of the results showed that FMD participants had reduced their biological age by 2.5 years on average.

“This study shows for the first time evidence for biological age reduction from two different clinical trials, accompanied by evidence of rejuvenation of metabolic and immune function,” Dr. Longo said. It lends more support to the FMD’s potential as a short-term periodic, achievable dietary intervention that can help people lessen their disease risk and improve their health without extensive lifestyle changes, he added.

“Although many doctors are already recommending the FMD in the United States and Europe, these findings should encourage many more healthcare professionals to recommend FMD cycles to patients with higher-than-desired levels of disease risk factors as well as to the general population that may be interested in increased function and younger age,” said Dr. Longo.

A Surprising Advantage of Exercise 

Looking to improve your fine motor skills? You can benefit from physical exercise both before and after practicing these skills, according to new research from the department of nutrition, exercise, and sports at the University of Copenhagen. This finding also can, among other things, make the way we rehabilitate more effective.

Before a violinist wants to learn a new piece or a surgeon stands at the training table to learn a new surgical technique, they might consider heading out for a bike ride or run. Once they’ve practiced the new skill, there’s good reason to put on their workout attire again. Indeed, being physically active and elevating one’s heart rate has the wonderful side effect of improving our ability to learn by increasing the brain’s ability to remember, stated the researchers. They showed that this effect also applies to the formation of motor memory, enabling us to recall and perform tasks such as riding a bike, driving a car, and lacing up our shoes, almost automatically.

“Our results demonstrate that there is a clear effect across the board. If you exercise before learning a skill, you will improve and remember what you have learned better. The same applies if you exercise after learning,” said Lasse Jespersen, PhD, first author of the study. Specifically, the researchers found around 10% improvement in people’s ability to remember a newly learned motor skill when exercise is included either before or after the new skill. “But our research shows that the greatest effect is achieved if you exercise both before and after,” Dr. Jespersen added.

“This is probably because physical activity increases the brain’s ability to change, which is a prerequisite for remembering,” explained co-author Jesper Lundbye-Jensen, PhD, who heads the department’s movement and neuroscience section. Specific parts of the brain are activated when a person engages in motor practice that requires the acquisition of fine motor skills. If the task is an activity that one knows well, like riding a bicycle, the centers are less active, but that all changes when learning something new. The brain undergoes actual changes, something that is essential for our ability to learn and remember new skills, a phenomenon known as brain plasticity. These changes occur not only while the new skill is acquired through practice but also in the hours after, when the memory is consolidated. This is why it is meaningful to be physically active even after we’ve engaged in something new.

The effect applies to everyone, including children, adolescents, and older adults, and in particular anyone who regularly needs to learn new skills. Moreover, the effects may hold significance for individuals undergoing rehabilitation, aiming to recover mobility and lost motor skills. 

“Typically, rehabilitation is divided between two or three different disciplines. In practice, this may mean that Mr. Smith will have physical training with a physiotherapist on one day, work with an ergonomist the next, and train cognitive abilities with a psychologist on the third. Our research suggests that it could be wise to plan rehabilitation so that these areas are considered together, as doing so could have a synergistic effect,” explained Dr. Lundbye-Jensen. “Coming back often entails hard work, and even slight improvements in efficiency can mean a lot to people in that situation.”

Sixty-seven test subjects were involved in the research project. To ensure comparable data, all subjects were young men between the ages of 18 and 35 who were not physically or mentally impaired in ways that could limit their learning ability and physical performance.

The researchers examined the subjects’ behavior and performance while reviewing one of four possible scenarios. First, the subjects either rested or exercised moderately on a bicycle. After that, they were subjected to a fine motor task in the form of a simple computer game that, with a small device on their fingertips, challenged and practiced their motor dexterity.

Next, they either exercised intensely on a fitness bike or rested. That meant there was one group that rested both before and after, one that trained both times, and two that trained once, either before or after. Their skill level and memory were tested again after seven days to assess whether what they had learned stuck.

As a somewhat unusual criterion, professional musicians and gamers were excluded as possible participants. “People with extensive experience in practicing motor skills typically start at a different level. While the motor task used in the research study was unknown to all, involving experts would have changed the dynamic from the get-go. But that doesn’t mean they wouldn’t benefit from the effects we’ve shown. To the contrary, in a future study, it could be exciting to investigate how exercise affects people with elite-level fine motor skills,” said Dr. Jespersen.
