Triple Berry Ice Cream Recipe, Spotlight on Ice Cream, Freezer Containers, Coffee for Brain Health, and How to Make Strength Your Superpower

Celebrate our country’s 250th birthday with this red, white, and blue ice cream that’s big on flavor as well as nutrients (read about the surprising benefits of real ice cream below). Thinking about having another cup of coffee? New research may give you the green light. And find out why a firm handshake should be your new superpower.

Triple Berry Ice Cream 

  • Triple berry ice cream Triple Berry Ice Cream

    Luscious and refreshing with chunks of frosty berries, this fruit- and EVOO-infused dessert is an ice cream lover’s dream. Ice cream isn’t complicated to make with a machine to churn it for you. If you have a KitchenAid stand mixer, buying its ice cream attachment is a cost-effective option; the bowl, as with other brands that don’t have a built-it compressor, needs 24 hours in the freezer before use.

    Ingredients

    • 2 cups heavy cream
    • 1 cup half-and-half
    • 3/4 cup sugar, divided use
    • 1/4 teaspoon coarse salt
    • 2 teaspoons vanilla extract
    • 2 cups mixed blueberries, raspberries, and strawberries, plus more for garnish if desired 
    • 2 tablespoons extra virgin olive oil

    Directions

    Step 1

    Make the ice cream base. Heat the heavy cream and half-and-half in a saucepan over medium heat until it reaches a simmer and forms a skin on the surface. Off the heat, whisk in 1/2 cup sugar, the salt, and the vanilla, whisking until the sugar is fully incorporated. Let the base come to room temperature, then refrigerate until cold (it can be made up to 3 days in advance).

    Step 2

    Just before you’re ready to make the ice cream, hull the strawberries and cut them into 1/2-inch dice. Add them to a bowl with the rest of the berries and the remaining 1/4 cup sugar. Toss well, then use a potato masher or pestle to mash the fruit just a bit. Fold in the olive oil and set aside. 

    Step 3

    Give the ice cream base a quick whisk, pour into your ice cream maker, and turn on the machine. Once the ice cream holds its shape, add in the berries with all their juices and finish churning. You can enjoy the ice cream as a soft serve after churning or, for a firmer consistency, transfer to a freezer-safe container and place in the freezer for 2 hours or more. Before serving, garnish portions with more berries if desired.

t’s too soon to call it a superfood, but a number of studies have found positive health links among people who eat real ice cream a couple of times a week. Scientists were so confounded by the results that they tried, at first, to dispel them. 

Long-term Harvard studies that analyzed data from nearly 190,000 people found a link between eating ice cream in moderation and a lower risk of diabetes along with better cardiovascular outcomes. One possible explanation is the metabolic effect of the milk fat globule membrane (MFGM), a complex, naturally occurring membrane that surrounds droplets of milk fat in real, whole dairy products. MFGM may help regulate cholesterol levels, reduce inflammation, and support healthy gut and metabolic function.

Most recently, a Swedish study published in the journal Neurology found that higher intake of high-fat cream (and high-fat cheese) was associated with a lower risk of all-cause dementia and that there were no such links between low-fat cheese, low-fat cream, and other dairy products. These results were based on the analysis of data from 27,670 participants in the Malmö Diet and Cancer cohort.

Experts are careful to say that there is no hard-and-fast proof that ice cream causes better health because these findings come from “observational” studies, so they show a link rather than a direct cause-and-effect. One important thing to keep in mind is that to confer any benefits, the ice cream must be made from full-fat cream. If you’re not making your own, read the fine print on supermarket brands and avoid products labeled “frozen dairy dessert.” They contain oils and other additives and can’t be called ice cream.

If you’ve made the switch from plastic to glass containers for refrigerated items, you’ll be happy to know that many brands can be used in the freezer, too, including products from Pyrex and Glasslock. Freezer-safe glass must be specially tempered to withstand fluctuations in temperature. Some can even go from freezer to microwave. Typically, the lids are plastic, so look for BPA-free designs. 

For Your Best Health: Coffee for Brain Health

For Your Best Health 

Coffee for Brain Health

Your morning coffee or tea could be quietly supporting brain function. A large, long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The benefits appeared strongest with 2 to 3 cups of coffee or 1 or 2 cups of tea daily—and held true even for people genetically predisposed to dementia.

Conducted by researchers from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard, the study examined data from 131,821 participants in the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study (HPFS). 

“When searching for possible dementia prevention tools, we thought something as prevalent as coffee may be a promising dietary intervention—and our unique access to high quality data through studies going on for more than 40 years allowed us to follow through on that idea,” said senior author Daniel Wang, MD, ScD, associate scientist with the Channing Division of Network Medicine in the Mass General Brigham Department of Medicine, assistant professor at Harvard Medical School and in the Department of Nutrition at Harvard Chan School, and an associate member at the Broad Institute. “While our results are encouraging, it’s important to remember that the effect size is small and there are lots of important ways to protect cognitive function as we age. Our study suggests that caffeinated coffee or tea consumption can be one piece of that puzzle.”

Coffee for brain health

Preventing dementia early is especially important because current treatments are limited and generally provide only modest benefits after symptoms begin. As a result, scientists are increasingly focusing on lifestyle factors, including diet, that may influence the development of cognitive decline. Coffee and tea contain compounds such as polyphenols and caffeine, which are thought to support brain health. These substances may help reduce inflammation and limit cellular damage, both of which are linked to cognitive decline. 

Previous research on coffee and dementia produced mixed results, often due to shorter study periods or limited data on long-term consumption patterns and different types of beverages. The NHS and HPFS datasets helped address these gaps. Participants were tracked for up to 43 years, with repeated evaluations of diet, dementia diagnoses, subjective cognitive concerns, and objective cognitive performance. Researchers analyzed how consumption of caffeinated coffee, tea, and decaffeinated coffee related to long-term brain health outcomes.

Among the more than 130,000 participants, 11,033 developed dementia over the course of the study. Individuals who consumed higher amounts of caffeinated coffee had an 18% lower risk of developing dementia compared with those who rarely or never drank it. They also reported lower rates of subjective cognitive decline (7.8% versus 9.5%) and performed better on certain objective cognitive tests.

“We also compared people with different genetic predispositions to developing dementia and saw the same results—meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing dementia,” said lead author Yu Zhang, MBBS, MS, PhD student at Harvard Chan School and a research trainee at Mass General Brigham.

Similar patterns were observed among tea drinkers, while decaffeinated coffee did not show the same associations. This suggests that caffeine may be an important factor behind the observed brain-related benefits, although more research is needed to confirm the underlying mechanisms.

Getting enough exercise is important for healthy aging. Now, new research suggests strength training plays a critical role. A large study led by researchers at the University at Buffalo (UB) found that older women with greater strength had a significantly lower risk of death, even after accounting for physical activity levels, cardiovascular fitness, and inflammation. The findings, published in JAMA Network Open, were based on more than 5,000 women between the ages of 63 and 99. Researchers tracked participants for eight years and discovered that women with stronger grip strength and faster sit-to-stand chair test times were more likely to live longer.

“If you don’t have enough muscle strength to get up, it is going to be hard to do aerobic activities, such as walking, which is the most commonly reported recreational activity in US adults ages 65 and older,” says study lead author Michael LaMonte, PhD, research professor of epidemiology and environmental health in UB’s School of Public Health and Health Professions.

“Muscular strength, in many ways, enables one to move their body from one point to another, particularly when moving against gravity,” Dr. LaMonte added. “Healthy aging probably is best pursued through adequate amounts of both aerobic and muscle-strengthening physical activities. When we no longer can get out of the chair and move around, we are in trouble.”

According to Dr. LaMonte, this is the largest study so far to examine how muscle strength relates to longevity in women over 60. Earlier large-scale studies often lacked detailed measures of physical activity, cardiovascular fitness, and inflammation, making it harder to isolate the role of muscular strength alone.

One of the study’s most notable findings was that women who did not meet current physical activity recommendations of at least 150 minutes of moderate-intensity aerobic activity each week still benefited from having greater muscle strength. Dr. LaMonte said this provides strong evidence that muscle-strengthening activities deserve greater emphasis in public health recommendations, particularly for older adults. “Because women ages 80 and older are the fastest-growing US age group, the importance of monitoring and maintaining muscular strength will have huge public health implications in the coming decades,” he said.

Muscle-building activities do not necessarily require expensive gym equipment or intense workouts. Researchers note that free weights, dumbbells, weight machines, and bodyweight exercises such as modified push-ups, wall presses, and knee bends can all help improve strength.

Dr. LaMonte pointed out that everyday household items can work as resistance tools. “Even using soup cans or books as a form of resistance provides stimulus to skeletal muscles and could be used by individuals for whom other options are not feasible.”

He advised that people talk to their healthcare provider before beginning a strength training program and that newcomers may benefit from guidance from a physical therapist or exercise specialist to help ensure safety and appropriate progress.

Cheesy Onion Wraps Recipe, Spotlight on Vidalia Onions, Storing Onions, Are You Getting Enough B12 and The Benefits of 30 Minutes of Weekly Exercise

Sandwich wraps are handy alternatives to bread but can lack flavor. My cheesy onion wraps are so good you’ll be tempted to eat them right out of the pan (be sure to let them cool off first!). This issue of the newsletter looks at new research on the all-important vitamin B12 and why many people could be short. And for those who have a hard time fitting in exercise, I’m including details of a report that suggests 30 minutes per week rather than per day can still be helpful.

Olive Toast

  • Olive Toast with Goat Cheese Olive Toast

    This makes a satisfying lunch and a great appetizer for your next get-together. I love the tangy, fruity taste of sumac, a spice that’s finally getting the attention it deserves. If you’ve got the grill on, drizzle olive oil on the bread and toast over the coals. 

    Ingredients

    • 2 tablespoons extra virgin olive oil, plus more for drizzling
    • 1 teaspoon lemon zest
    • 2 tablespoons fresh lemon juice  
    • 1 medium garlic clove, grated
    • 1/2 teaspoon sumac, such as Wild Sumac
    • 1/4 teaspoon coarse sea salt
    • 1/4 teaspoon freshly ground black peppercorns like Vine-Ripened Black Peppercorns
    • 1/8 teaspoon peperoncino (Italian crushed red pepper flakes)
    • 4 ounces each pitted Castelvetrano and Kalamata olives
    • 2 tablespoons chopped fresh flat-leaf parsley
    • 8 baguette or crusty whole-grain bread slices
    • 8 ounces goat cheese at room temperature
    • 1/4 cup chopped walnuts

    Directions

    Step 1

    In a medium bowl, whisk together the olive oil, lemon zest and juice, garlic, sumac, salt, pepper, and peperoncino. Coarsely chop the olives and add to the bowl along with the parsley; let marinate for 30 minutes.

    Step 2

    When ready to assemble, toast the bread. Spread each slice with equal amounts of goat cheese, then top with the walnuts and the olive mixture. Drizzle with olive oil and serve.

    Yields 4 lunch or 8 appetizer servings

Healthy Ingredient Spotlight: Vidalia Onions

Healthy Ingredient Spotlight

Vidalia Onions

Grown in a limited area in Georgia, these onions are super sweet, thanks to their low sulfur content, which makes them less pungent and tear-inducing than other onion varieties. Their mild flavor profile means you can enjoy them raw, but they’re equally delicious cooked.

These onions are a good source of vitamin C, B6, and folate, potassium and manganese as well as quercetin, an antioxidant known for its anti-inflammatory properties, and fiber. They’re available from April to August; look for their trademark logo as well as their flatter shape.

Storing Onions

Vidalias have a high moisture content, and some experts recommend wrapping each one in a paper towel and storing them in the crisper drawer of your fridge. If you’re going to be using them in a few days, you can keep them on a rack in a cool, dry cabinet. But always keep any onions far away from potatoes because the ethylene gas produced by onions will cause your spuds to spoil prematurely. 

For Your Best Health: Are You Getting Enough B12?

For Your Best Health 

Are You Getting Enough B12?

Vitamin B12 is essential for helping your body make DNA, red blood cells, and healthy nerve tissue. While there are guidelines for daily intake, that amount may not actually be enough to protect the brain in later years. Researchers at the University of California San Francisco (UCSF) found that older adults with “normal” but lower levels of active B12 showed signs of slower thinking, delayed visual processing, and more damage to the brain’s white matter — the communication highways that help different brain regions work together. The findings raise the possibility that some people may be told their B12 status is fine while their brains are already showing early signs of strain.

For the study, published in Annals of Neurology, researchers enrolled 231 healthy older adults through the Brain Aging Network for Cognitive Health (BrANCH) study at UCSF. The participants had an average age of 71, and none had dementia or mild cognitive impairment. Their average blood B12 level was 414.8 pmol/L, far above the US minimum cutoff of 148 pmol/L. Instead of relying only on total B12, the researchers focused on the biologically active form of the vitamin, which may better reflect how much B12 the body can actually use. The study focused on older adults, a group that may be especially sensitive to lower B12 because absorption can become less efficient with age. Some medications, digestive conditions, and diets low in animal-based foods can also increase the risk of low B12.

After adjusting for age, sex, education, and cardiovascular risk factors, the team found that participants with lower active B12 had slower processing speed on cognitive tests. The effect was stronger with older age. They also had delayed responses to visual stimuli, pointing to slower visual processing and reduced brain signaling efficiency. 

MRI scans added another warning sign. Participants with lower active B12 had a higher volume of white matter lesions, which are areas of brain injury that have been linked to cognitive decline, dementia, and stroke risk. Even in this relatively healthy group, lower levels of active B12 were linked to slower thinking, slower visual processing, and more visible injury in the brain’s white matter. 

The work was led by senior author Ari J. Green, MD, of the UCSF Departments of Neurology and Ophthalmology and the Weill Institute for Neurosciences. Dr. Green and his colleagues said the results call attention to a possible weakness in current B12 guidelines. The minimum threshold used to define deficiency may not capture early functional changes in the nervous system.

“Previous studies that defined healthy amounts of B12 may have missed subtle functional manifestations of high or low levels that can affect people without causing overt symptoms,” said Dr. Green, noting that clear deficiencies of the vitamin are commonly associated with a type of anemia. “Revisiting the definition of B12 deficiency to incorporate functional biomarkers could lead to earlier intervention and prevention of cognitive decline.” 

The findings suggest that low but technically normal B12 could have broader effects than previously recognized. These levels could “impact cognition to a greater extent than what we previously thought and may affect a much larger proportion of the population than we realize,” said co-first author Alexandra Beaudry-Richard, MSc, who is currently completing her doctorate in research and medicine at the UCSF Department of Neurology and the Department of Microbiology and Immunology at the University of Ottawa.

“In addition to redefining B12 deficiency, clinicians should consider supplementation in older patients with neurological symptoms even if their levels are within normal limits,” she said. “Ultimately, we need to invest in more research about the underlying biology of B12 insufficiency, since it may be a preventable cause of cognitive decline.”

The UCSF findings do not prove that lower active B12 directly causes cognitive decline, and they do not mean every older adult should begin taking supplements without medical guidance. They do, however, suggest that the current definition of B12 deficiency may be too blunt for brain health.

The Benefits of 30 Minutes of Weekly Exercise 

Current health recommendations suggest exercising for at least 2.5 hours each week, with 5 hours considered even better. For many people, that target can seem overwhelming. Here’s music to their ears: According to researchers at the Norwegian University of Science and Technology (NTNU), you may not need hours at the gym to boost your health after all. Studies from the past two decades suggest that just 30 minutes of high-intensity exercise per week can improve health. That works out to roughly 4.3 minutes per day or about 10 minutes every other day. 

The important part is intensity. The activity needs to be strenuous enough to leave you noticeably out of breath. If you use a heart rate monitor, researchers say your heart rate should reach about 85 percent of your maximum. However, special equipment is not necessary. A simple way to judge intensity is by how difficult it is to talk. You should still be able to speak in short sentences, but you should not be able to sing or carry on a continuous conversation comfortably.

“The biggest reported challenge regarding exercise is lack of time. But with intense, short workouts, this is no longer a valid excuse,” said Ulrik Wisløff, a professor at NTNU and head of CERG, a research group that studies the health effects of exercise. Researchers say even a small amount of high-intensity activity can improve cardiovascular fitness, which plays a major role in long-term health. “Cardiovascular fitness is the best indicator of current and future health. Good cardio fitness reduces the risk of over 30 lifestyle diseases as well as premature death by 40 to 50 percent,” explained Wisløff.

CERG first documented these effects in a 2006 study that analyzed health information from 60,000 people. Since then, additional large studies from Norway and other countries have reported similar findings.

Intense home exercise for heart health

Rather than doing one intense 30-minute workout each week, it’s best to spread out the sessions, said Wisløff. Blood pressure and blood sugar control improve for 24 to 48 hours after a workout that pushes you hard enough to become breathless for several minutes. Because of these short-term benefits, divide exercise across two to four days per week whenever possible.

That does not necessarily mean sprinting at full speed or using the highest resistance setting on an exercise bike. “Your own personal fitness level determines what gives you a high heart rate,” Wisløff said. “If you are not very fit, simply taking a brisk walk may be enough. Having said that, you need to walk fast enough that you get quite out of breath. You can then increase the intensity as your fitness improves. Short intervals are effective. For example, this could be bursts of 45 seconds with 15-second breaks. Or like in Tabata workouts, with intense 20-second intervals interspersed with 10-second breaks. Otherwise, 4×4 intervals are recognized as highly effective for increasing oxygen uptake.”

“Fitness is something you have to maintain. Cardio fitness and strength decline quickly when not maintained, especially as you get older,” said Atefe R. Tari, PhD, a researcher and head of CERG’s initiative on exercise and brain health. Strength training is also considered important, particularly for middle-aged and older adults. “We know that strength training is important, especially for middle-aged and older adults. There is limited research on how strength training affects lifespan, but a HUNT study exploring this is due to be published soon,” said Wisløff. “Physical health and brain health are closely linked, and cardio fitness is key here as well. Exercise leads to the formation of new brain cells,” added Dr. Tari.

Wisløff and Tari are now encouraging Norwegian health authorities to revise the country’s official exercise recommendations, arguing that exercise intensity should receive greater emphasis.

Hawaiian-Inspired Sheet Pan Chicken Recipe, Spotlight on Pineapple, Choosing a Rimmed Sheet Pan, Reversing Prediabetes, and Countering Joint Pain 

Sheet pan dinners are still all the rage because they allow you to cook your meal in one pan with an easy clean-up as the capper. While this recipe didn’t originate in our 50th state, it’s inspired by one of Hawaii’s most iconic crops, juicy pineapples. Along with red onions and bell peppers, they create the sweet and tangy taste this dish is known for. I’m sharing health news about two of the most prevalent conditions affecting Americans: prediabetes and joint pain.

Hawaiian-Inspired Sheet Pan Chicken

  • Hawaiian-Inspired Sheet Pan Chicken Hawaiian-Inspired Sheet Pan Chicken

    This recipe is a crowd-pleaser and a delicious answer to the question, “What’s for dinner?” Note: A Microplane is perfect for grating the garlic and the ginger right over the mixing bowl for the marinade.

    Ingredients

    For the marinade:

    • 1/3 cup extra virgin olive oil
    • 1/3 cup reduced-sodium soy sauce
    • 3 tablespoons brown sugar
    • 4 garlic cloves, grated
    • 2 teaspoons grated fresh ginger
    • 1 teaspoon dry mustard
    • 1 teaspoon wild sumac
    • 1/2 teaspoon red pepper flakes

    For the chicken and vegetables:

    • 4 cups pineapple chunks from a fresh pineapple
    • 1 large red bell pepper 
    • 1 large yellow bell pepper
    • 1 large red onion
    • 1-1/2 pounds boneless, skinless chicken breasts or thighs

    Directions

    Step 1

    In a medium bowl, whisk together the marinade ingredients; set aside. 

    Step 2

    Cut each pepper into 1-inch squares and add to a large bowl. Peel and cut the onion into 8 wedges, then cut each wedge in half; add to the bowl with the bell peppers. Finally, cut the chicken into 1-inch cubes and add to the bowl. Pour on the marinade and toss to coat. Marinate for 1 hour (you can also marinate overnight in the fridge).

    Step 3

    While the chicken marinates, prepare the pineapple. Start by cutting off and discarding the top and bottom. Stand it up on your cutting board and use a serrated knife, working from top to bottom, to cut off the peel in strips. Next, use the knife to cut the pineapple in half, then into quarters. Make V-shaped cuts in each quarter to remove and discard the tough core. Cut each of the four sections into roughly 1-inch pieces. Transfer 4 cups to a bowl and set aside (enjoy any leftover pineapple at another meal).

    Step 4

    When ready to cook, preheat your oven to 400°F and line a rimmed sheet pan with parchment paper. Transfer the chicken and vegetables to the sheet pan and roast for 15 minutes. Then carefully top with the pineapple and any juice in the bowl; roast for another 10 minutes.

    Step 5

    Set your oven to broil and place the sheet pan under your broiler for 3 minutes for a caramelized finish.

If you love pineapple for its sweet taste, you’ll love it even more for its potential health benefits. According to a comprehensive review published in the journal Food Research International, it’s a rich source of bioactive compounds, dietary fiber, and minerals. Research also suggests it has anti-inflammatory and antioxidant properties, supports heart health and digestion, and may even help lower diabetes risk.

Choosing a ripe pineapple takes a little detective work. Look for a vibrant golden-yellow color rising from its base and a crown of green leaves. It should have a tropical aroma, firm skin, a slight give when squeezed, and an underside free of any white splotches, which could be mold.

Sheet pans are great not only for roasting vegetables and sheet-pan dinners but also for baking cookies and certain cakes like genoise layers that are fairly thin. The sides hold in juices released during cooking and are also easy to grab with oven mitts. 

The most highly rated pans are made of aluminum, and the brand name that comes up in review after review is Nordic Ware, praised for even cooking and resistance to warping. When the pan is lined with parchment paper, clean-up is a breeze.

For Your Best Health: Reversing Prediabetes

For Your Best Health 

Reversing Prediabetes

People diagnosed with prediabetes, a condition that affects up to one in three adults, have traditionally been advised to eat healthier and shed pounds to reduce the risk of progression to type 2 diabetes. This message has remained largely unchanged for decades, yet the results have been mixed. Diabetes rates continue to rise worldwide, and many individuals with prediabetes struggle to meet weight-loss targets. As a result, they often feel discouraged while their risk remains high.

New findings published in Nature Medicine point to a different path. The research shows that prediabetes can go into remission — meaning blood sugar levels return to normal — even in the absence of weight loss. In fact, about one in four people participating in lifestyle programs were able to normalize their blood sugar without losing weight. Even more striking, this type of remission offers the same level of protection against future diabetes as remission achieved through weight loss.

How can blood sugar improve without a drop in body weight or even with weight gain? The study states that the answer appears to lie in where fat is stored in the body. Not all fat has the same effect on health. Visceral fat, which surrounds internal organs deep in the abdomen, is particularly harmful. It promotes chronic inflammation and disrupts insulin — the hormone responsible for regulating blood sugar. When insulin does not function properly, blood glucose levels rise.

On the other hand, subcutaneous fat — the fat just beneath the skin — can actually support healthier metabolism. This type of fat releases hormones that help insulin work more efficiently. The study found that individuals who reversed prediabetes without losing weight tended to shift fat away from their abdominal organs and toward areas under the skin, even when their overall weight did not change.

The researchers also found that natural hormones, similar to those targeted by medications like Wegovy and Mounjaro, play an important role. These hormones, especially GLP-1, help pancreatic beta cells release insulin when blood sugar rises. People who achieved remission without weight loss appeared to boost this hormone system naturally, while reducing the influence of other hormones that raise glucose levels.

Instead of focusing only on the number on the scale, people with prediabetes may benefit from strategies that influence how fat is distributed in the body. Certain dietary patterns can help. Healthy fats — including the monounsaturated fats in olive oil and olives, and the polyunsaturated fats in fish, nuts, and seeds typical of a Mediterranean-style diet — may help reduce visceral fat. Regular endurance exercise can also lower abdominal fat, even when overall weight stays the same.

This does not mean weight loss should be ignored. Losing weight still supports overall health and reduces diabetes risk. However, the research suggests that normalizing blood sugar should be a primary goal, regardless of whether weight changes.

For many people who have struggled with traditional weight-loss programs, this opens the door to meaningful improvements through metabolic changes rather than a sole focus on weight.

Healthcare providers may also need to expand their approach. Tracking blood sugar improvements and encouraging fat redistribution through targeted nutrition and exercise could provide alternative strategies for patients who find weight loss difficult.

Countering Joint Pain 

An article written by Dr. Clodagh Toomey, physiotherapist and associate professor at the School of Allied Health, University of Limerick in Ireland, and published in The Conversation, a nonprofit news organization that shares expert findings with the public, serves as a great reminder that the most powerful treatment to ease joint pain and the stiffness of osteoarthritis isn’t surgery or medication, but rather exercise: Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage.

Stiff knees, sore hips, and persistent joint pain are often brushed off as normal signs of aging. But osteoarthritis, the most common joint disease worldwide, is not being treated in line with what research shows, and in many countries and healthcare systems, people are rarely directed toward the one therapy proven to reduce pain and protect joints. Specifically, the article pointed out that in countries such as Ireland, the UK, Norway, and the US, fewer than half of people diagnosed with osteoarthritis are referred to exercise programs or physical therapy by their primary care provider. More than 60 percent receive treatments that clinical guidelines do not recommend, and about 40 percent are referred to a surgeon before nonsurgical options have been properly explored.

To understand why this matters, it helps to look at how joints function, wrote Dr. Toomey. Regular physical activity does more than ease symptoms. It can biologically and physically lower the risk of developing osteoarthritis and reduce its severity. Cartilage, the smooth tissue that cushions the ends of bones, does not have its own blood supply. It depends on movement to stay healthy. When you walk or put weight on a joint, cartilage is gently compressed, pushing fluid out. When the pressure is released, it draws fluid back in, bringing nutrients and natural lubricants with it. Each step helps nourish and maintain the joint.

This is why describing osteoarthritis as simple “wear and tear” is misleading. Joints are not like tires that inevitably break down over time. Instead, osteoarthritis is better understood as a long process of breakdown and repair. Regular movement plays a central role in supporting healing and maintaining the health of the entire joint.

Osteoarthritis affects not only cartilage but also the entire joint, including joint fluid, underlying bone, ligaments, surrounding muscles, and even the nerves that control movement. Targeted exercise addresses many of these components at once. Muscle weakness is one of the earliest warning signs of osteoarthritis, and resistance training can help reverse it. Research shows that weak muscles increase the risk of both developing osteoarthritis and experiencing faster progression.

Swimming to counter arthritis

Dr. Toomey pointed out that neuromuscular exercise programs designed specifically for people with hip and knee osteoarthritis and led by physical therapists can be especially beneficial. For instance, those participating in the Denmark-based program called GLA:D® (Good Life with osteoArthritis in Denmark) reported meaningful reductions in pain, better joint function, and improved quality of life lasting up to 12 months after finishing the program.

Black-and-White Cookies Recipe, Spotlight on Vanilla Pods, Rotating Cookie Sheets, Coffee and Brain Health and A Surprising Way to Make Exercise Work Better

Vanilla or chocolate? You don’t have to decide when you indulge in a classic black-and-white cookie, the treat that’s more cake than biscuit with two luscious glazes. I’m also sharing two interesting food-related studies. According to the first, drinking coffee or tea could protect brain health. And according to the second, the keto diet could boost the effects of exercise for some people with high blood sugar.

Black-and-White Cookies

  • Black-and-white cookies Black-and-White Cookies

    Why choose between vanilla and chocolate when you can have both? The iconic black-and-white cookie settles the age-old debate once and for all — a pillowy, cake-like base topped with two luscious glazes that are as striking to look at as they are to eat.

    Ingredients

    For the cookies: 

    • 3/4 cup all-purpose flour 
    • 3/4 cup cake flour 
    • 1/4 cup golden or white whole wheat flour
    • 1/2 teaspoon baking powder  
    • 1/4 teaspoon baking soda 
    • 1/4 teaspoon salt 
    • 6 tablespoons unsalted butter, softened 
    • 1 cup granulated sugar 
    • 1/4 cup extra virgin olive oil
    • 1 large egg 
    • 2 teaspoons vanilla extract 
    • 1/3 cup sour cream 

    For the glazes:

    • 3 cups confectioners’ sugar, sifted, more if needed
    • 7 tablespoons whole milk, divided use  
    • 2 tablespoons corn syrup 
    • 2 teaspoons vanilla extract 
    • 1/2 teaspoon salt 
    • 4 tablespoons Dutch-processed cocoa powder, sifted 
    • 2 ounces dark chocolate, melted

    Directions

    Step 1

    Place an oven rack in the center position and preheat your oven to 350°F. Line 2 rimmed sheet pans with parchment paper; set aside. Combine the flours, baking powder, baking soda, and salt in a bowl; set aside.

    Step 2

    Using a stand mixer fitted with the paddle attachment, beat butter and sugar on medium-high speed until pale and fluffy, about 2 minutes. Add the olive oil, egg, and vanilla and mix until well blended. Turn off the machine and use a spatula to scrape up the bottom of the bowl to make sure no clumps of butter remain. 

    Step 3

    On the lowest speed, add half the flour mixture, then the sour cream, then the rest of the flour. Again, use the spatula to incorporate any batter stuck on the bottom of the bowl. Turn back on the mixer if needed to fully incorporate the flour. The batter will be thick.

    Step 4

    Use a 2¼” (¼-cup) ice cream scoop to form and release each cookie onto the sheet pans, evenly spacing 6 per pan. For the most even results, bake one sheet pan at a time in the middle rack. Bake for 10 minutes, rotate the pan, and bake another 10 minutes, just until the cookie edges are barely browned. Cool for 10 minutes, then transfer to wire racks to cool completely.

    Step 5

    When the cookies are completely cooled, make the vanilla glaze. In a large bowl, whisk the sugar, 5 tablespoons milk, corn syrup, vanilla, and salt until smooth; it should be thick enough to drop from the whisk in a ribbon. If too thin, whisk in more confectioners’ sugar, 1 tablespoon at a time. 

    Step 6

    Working one cookie at a time, use a thin offset spatula to glaze one half of each cookie, using about half of the vanilla glaze (reserve the rest for the chocolate glaze). Let the glaze set for about 15 minutes. Rinse and dry the spatula. 

    Step 7

    In a small bowl, whisk the remaining 2 tablespoons of milk and a large spoonful of the vanilla glaze into the cocoa until smooth. Whisk in the melted chocolate, then scrape it into the bowl of reserved vanilla glaze. Whisk until smooth. Use the spatula to spread the chocolate glaze on the unglazed side of each cookie (don’t worry about being too exact with the dividing line). 

    Step 8

    Let the glaze set for 30 minutes before eating. Allow the cookies to dry completely, an hour or more, before storing them in a single layer in cookie tins.

    Yields 12 cookies

Vanilla Pods

Vanilla pods and flower

One of the most tantalizing tastes in the world, vanilla comes from pods that grow on a specific orchid, Vanilla planifolia—the only orchid grown commercially for its fruit. Producing the coveted pods is labor-intensive. Following hand pollination, it takes nine months for the pods to ripen and another three months to cure. (The process to create vanilla extract and vanilla paste takes even more time.) 

Within each vanilla pod are thousands of seeds that add rich flavor and visual appeal to baked goods, custards, and ice cream. To get at the seeds, use the tip of a sharp paring knife to score the length of the pod, then one side of the blade to scrape them out. Add the leftover pod to a jar of sugar to make your own vanilla sugar for other recipes.

Rotating Cookie Sheets

When baking cookies, rotating the sheet pan or cookie sheets halfway through the bake time is better for even rising and browning. This is true even when baking one sheet at a time. If a recipe suggests baking two sheets at one time, you want to not only rotate each one, but also switch their positions in the oven.  

For Your Best Health: Coffee and Brain Health

Coffee and Brain Health

Coffee for health

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 oYour morning coffee or tea could be quietly supporting your brain health. A large prospective cohort study conducted by researchers from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard examined data from 131,821 participants in the Nurses’ Health Study (NHS) and Health Professionals Follow-Up Study (HPFS). It found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia, slower cognitive decline, and better preservation of cognitive abilities. The benefits appeared strongest at 2 to 3 cups of coffee or 1 to 2 cups of tea daily—and even held true for people genetically predisposed to dementia. The study was published in JAMA.

“When searching for possible dementia prevention tools, we thought something as prevalent as coffee may be a promising dietary intervention—and our unique access to high quality data through studies that have been going on for more than 40 years allowed us to follow through on that idea,” said senior author Daniel Wang, MD, ScD, associate scientist with the Channing Division of Network Medicine in the Mass General Brigham Department of Medicine, and assistant professor at Harvard Medical School and in the Department of Nutrition at Harvard Chan School. “While our results are encouraging, it’s important to remember that the effect size is small and there are lots of important ways to protect cognitive function as we age. Our study suggests that caffeinated coffee or tea consumption can be one piece of that puzzle.”

Preventing dementia early is especially important because current treatments are limited and generally provide only modest benefits after symptoms begin. As a result, scientists are increasingly focusing on lifestyle factors, including diet, that may influence the development of cognitive decline.

Coffee and tea contain compounds such as polyphenols and caffeine, which are thought to support brain health. These substances may help reduce inflammation and limit cellular damage, both of which are linked to cognitive decline. Previous research on coffee and dementia has produced mixed results, often due to shorter study periods or limited data on long-term consumption patterns and different types of beverages.

“We also compared people with different genetic predispositions to developing dementia and saw the same results, meaning coffee or caffeine is likely equally beneficial for people with high and low genetic risk of developing dementia,” said lead author Yu Zhang, MBBS, MS, a PhD student at Harvard Chan School and a research trainee at Mass General Brigham.f 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.

A Surprising Way to Make Exercise Work Better

Advice about staying healthy often centers on regular exercise and limiting fatty foods. Physical activity helps people shed excess weight, build muscle, and strengthen the heart. It also improves the body’s ability to absorb and use oxygen to produce energy, which is considered one of the most reliable indicators of long-term health and longevity.

However, people with high blood sugar frequently miss out on some of these benefits from exercise, particularly improvements in how efficiently their bodies use oxygen. Elevated blood sugar raises the risk of heart and kidney disease. It can also interfere with the ability of muscles to increase oxygen uptake during physical activity. For people facing this challenge, new research suggests an unexpected possibility. Instead of reducing fat intake, increasing it might help.

A study led by Sarah Lessard, PhD, associate professor at the Fralin Biomedical Research Institute at VTC Center for Exercise Medicine Research and exercise medicine researcher, and published in Nature Communications examined how diet affects exercise response. The team found that mice fed a high-fat ketogenic diet experienced a drop in high blood sugar, also known as hyperglycemia. Their bodies also became more responsive to exercise.

“After one week on the ketogenic diet, their blood sugar was completely normal, as though they didn’t have diabetes at all,” said Dr. Lessard. “Over time, the diet caused remodeling of the mice’s muscles, making them more oxidative and making them react better to aerobic exercise.”

The ketogenic diet gets its name from ketosis, a metabolic state in which the body switches from using sugar as its main fuel to burning fat. Because the diet relies on high-fat foods and severely limits carbohydrates, it contrasts with the low-fat diets traditionally recommended by many health experts.

The keto diet has been associated with health benefits for certain conditions, including epilepsy and Parkinson’s disease. Historically, it was also used to manage diabetes. Before insulin was discovered in the 1920s, doctors sometimes relied on this approach to help lower blood sugar.

Dr. Lessard’s earlier studies showed that people with elevated blood sugar often have reduced exercise capacity. This led her to explore whether a ketogenic diet could help restore the body’s ability to adapt to exercise. In the study, mice ate a high-fat, low-carbohydrate diet and ran regularly on exercise wheels. Over time, their muscles developed more slow-twitch fibers, which are linked to greater endurance. “Their bodies were more efficiently using oxygen, which is a sign of higher aerobic capacity,” Dr. Lessard said.

According to Dr. Lessard, exercise benefits nearly every tissue in the body, including fat tissue. But growing evidence suggests that the greatest improvements in health occur when diet and exercise are combined rather than treated as separate strategies.

“What we’re really finding from this study and from our other studies is that diet and exercise aren’t simply working in isolation,” said Dr. Lessard. “There are a lot of combined effects, and so we can get the most benefits from exercise if we eat a healthy diet at the same time.”

She plans to expand the research to human participants to determine whether people experience the same improvements seen in mice. She also points out that following a ketogenic diet can be difficult. For many people, a less restrictive eating plan such as the Mediterranean diet may be easier to maintain while still supporting healthy blood sugar levels. This approach includes carbohydrates from whole foods like fruits, vegetables, and whole grains instead of eliminating carbohydrates entirely. “Our previous studies have shown that any strategy you and your doctor have arrived at to reduce your blood sugar could work,” she said.
