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. 

Asparagus in the Milanese Style

  • 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.

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.

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.”

Shrimp with Cellophane Noodles Recipe, Spotlight on Cellophane Noodles, Shopping for Frozen Shrimp, Control Blood Pressure to Reduce Dementia Risk and The Longevity Benefits of Varied Exercise

Looking for a change of pace for dinner? Thai cuisine boasts a wide array of flavorful dishes that are often simple to make and totally satisfying. Shrimp with cellophane noodles cooks up in under a half hour, from prep to finish. This edition’s health news includes ways to reduce dementia risk as well as to increase lifespan.

Shrimp with Cellophane Noodles

  • Shrimp with cellophane noodles Shrimp with Cellophane Noodles

    This classic Thai dish is a delicious one-pot meal that also happens to be gluten free. High-quality wild-caught frozen shrimp make a great option; let them defrost overnight in the fridge.

    Ingredients

    • 8 ounces cellophane (mung bean) noodles
    • 2 tablespoons soy sauce
    • 3 tablespoons oyster sauce
    • 1 tablespoon toasted sesame oil
    • 1 tablespoon brown sugar
    • 1 pound large shrimp, peeled and deveined
    • 1/2 teaspoon freshly ground black pepper
    • 2 cups homemade or low-sodium store-bought chicken broth
    • 2 tablespoons extra virgin olive oil, plus more for the pot
    • 1 tablespoon freshly grated ginger
    • 2 tablespoons minced garlic
    • 6 scallions, trimmed and sliced into small pieces
    • 1/3 cup each finely chopped fresh cilantro and peanuts (optional)
    • Lime wedges

    Directions

    Step 1

    Soak the noodles in a large bowl of fresh water at room temperature to soften, about 15 minutes. 

    Step 2

    In a separate bowl, whisk together the soy and oyster sauces, sesame oil, and sugar. Transfer 2 tablespoons of the mix to another bowl along with the shrimp and black pepper; toss well. 

    Step 3

    Add the broth to the bowl with the remaining soy sauce mixture.

    Step 4

    Once the noodles have softened, drain and use kitchen shears to cut the strands into thirds. Lightly brush a large Dutch oven with olive oil and heat it to medium-high heat. When hot, add the 2 tablespoons olive oil, ginger, garlic, and scallions and sauté until fragrant, about 3 minutes. Stir in the noodles and then spread out in an even layer. Top with an even layer of shrimp, drizzling on any shrimp marinade from the bowl, then slowly add the broth mixture. Turn the heat down to a simmer and cover the pot. Simmer for 10 minutes or until the shrimp and the noodles are cooked through. To serve, spoon equal amounts into deep bowls and top with cilantro and peanuts, if using, and a lime wedge.

Cellophane Noodles

Cellophane noodles are an unusual type of noodle because they’re made from mung beans, sweet potato, or tapioca rather than wheat. They also go by many names, including glass noodles, bean thread, or Chinese vermicelli. While they’re generally gluten free, be sure to check labels to see whether they were made in the same facility as any gluten products to avoid any potential cross-contamination.

The noodles come dried and should be soaked according to the recipe or package instructions before cooking. You know they’re done when they’re transparent and soft but take care not to overcook them or else they’ll become mushy. Like many types of noodles, they take on the flavors of other ingredients in a recipe, so they lend themselves to many cuisines.

Shopping for Frozen Shrimp

Flash-frozen shrimp

Buying flash-frozen shrimp is a great choice because it can often be fresher than “fresh” shrimp. But there are many types of frozen shrimp available, so it’s important to be selective. First and foremost, choose wild-caught, not farm-raised, shrimp. Look for certifications from the Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC); these show that the shrimp were sustainably sourced, are traceable, and were harvested from healthy populations with minimal environmental impact before being individually quick frozen (or IQF)—shrimp frozen separately won’t be clumped in a block. For more convenience, look for frozen shrimp that’s already been shelled and deveined—when you buy a pound, you’re getting the full pound. A pound of shrimp with the shell nets only about 13 ounces of meat.

Control Blood Pressure to Reduce Dementia Risk

Researchers examined two known risk factors for developing dementia—one genetic and one relating to blood vessel damage in the brain. They wanted to know how much a person’s dementia risk might increase if they had both factors. In their study, published in the journal Annals of Neurology, they found that while the likelihood of developing dementia does rise if a person has both risk factors, there is a silver lining: The vascular component is within a person’s control, offering a route for minimizing dementia risk even if they have higher genetic risk.

“Our study addressed whether these two known risk factors act additively or multiplicatively to increase the risk of incident all-cause dementia,” says senior author Adam de Havenon, MD, associate professor of neurology at Yale School of Medicine. “We wanted to show that controlling vascular risk factors like high blood pressure could prevent harmful brain changes, meaning that even those with bad genetic luck could avoid the worst outcomes.”

The study used data from the Atherosclerosis Risk in Communities study and the UK Biobank. The team assessed two measures: white matter hyperintensity (WMH) and whether a person was a carrier of the ε4 variant of the APOE gene. WMH are lesions, or scar tissue areas, in the brain that show up as bright white spots on an MRI. They’re associated with damage to the small blood vessels in the brain, which can be caused by high blood pressure and can accumulate over time. The APOE gene encodes for a protein involved in transporting fat, such as cholesterol. When people have the ε4 variant, they carry a higher risk of developing Alzheimer’s disease.

The researchers found that participants with both a high WMH burden and at least one APOE ε4 allele faced elevated dementia risk compared to those with neither risk factor. These effects, however, were additive rather than multiplicative, meaning each factor contributed its own risk increase rather than also exacerbating the effect of the other factor. “This tells us something really important,” Dr. de Havenon explained. “Even if you’ve been dealt a bad genetic hand with APOE ε4, you’re not destined for dementia. The vascular component is modifiable.”

For instance, the health factors that can contribute to the development of WMH can be prevented or slowed through blood pressure management, diabetes control, and other cardiovascular interventions, he explained. “It’s really a two-hit scenario,” said Dr. de Havenon. “If you have APOE ε4 and you don’t take care of your vascular health, then you’re in a high-risk group. But having the APOE ε4 genotype is not a foregone conclusion for developing dementia later in life. Our analysis suggests that while the gene increases risk, the ultimate outcome is highly dependent on other factors. My hope is that people who find out they have this genetic mutation will be very serious about their vascular risk factors.”

The Longevity Benefits of Varied Exercise

Weight-lifting class for improved muscle mass

It’s well known that physical activity levels have consistently been linked with lower mortality, but there’s been limited evidence about the role of specific physical activities, each of which can have distinct benefits. What had been unclear was whether long-term engagement in multiple physical activities has additional benefits. To answer that question, an international team of researchers analyzed physical activity data that spans more than 30 years from over 111,000 participants in the Nurses’ Health Study and the Health Professionals Follow-Up Study. 

Their study, published in BMJ Medicine, found that regularly engaging in a variety of physical activities may be the best way to prolong your lifespan. Specifically, participants with the broadest range of physical activities had a 19% lower risk of death from all causes and a 13%-14% lower risk of death from heart disease, respiratory disease, cancer, and other causes. Activities included walking, running, racquet sports, bicycling, rowing, swimming, and weight training. Only swimming couldn’t be identified as a known contributor to these results because it wasn’t possible to determine the intensity at which participants swam; further study is needed. On the other hand, the researchers confirmed the importance of weight training, a non-aerobic form of exercise that helps maintain muscle mass.

Their findings support the notion that engaging in a diverse range of physical activity types, alongside increasing total physical activity levels, may help reduce the risk of premature death and extend lifespan, adding a crucial new dimension to the advice to stay active: Variety is just as important as volume.

Black Dal Recipe, Spotlight on Black Lentils, How to Store Lentils, Sorbitol and The Liver, and More Muscle, Younger Brain

When it comes to dark leafy greens, kale occupies a heightened position thanks to its wide range of nutrients. And yet, shockingly, researchers have found that the body doesn’t absorb as many of them as hoped…unless you eat it with a healthy fat source, like extra virgin olive oil. I’m also sharing the trick to make this hearty green more tender, which also involves olive oil. It’s another reason why these two ingredients are a match made in heaven.

Black Dal

  • Indian black dal Black Dal

    If you’re new to lentils, this flavorful recipe makes a great introduction. I’ve streamlined the number of spices used in traditional recipes because garam masala already incorporates the essentialscoriander, black pepper, cardamom, cinnamon, cloves, ginger, and nutmeg, among others. This makes a hearty meatless meal, a soup, or a side dish—scoop it up with a piece of your favorite Indian bread.

    Ingredients

    • 2 cups black lentils
    • 3 tablespoons extra virgin olive oil, plus more for drizzling
    • 1 small onion, minced
    • 2-inch piece ginger, minced
    • 2 garlic cloves, minced
    • One 6-ounce can tomato paste
    • 2 teaspoons garam masala
    • 1/2 teaspoon cayenne pepper
    • 1 cinnamon stick
    • 1 cup homemade or store-bought low-sodium chicken or vegetable broth
    • 2 tablespoons unsalted butter
    • 1/2 cup heavy cream
    • Optional garnish: chopped fresh cilantro

    Directions

    Step 1

    Rinse the lentils, and then put them in a stockpot or Dutch oven. Add enough cold water to cover them by 2 or 3 inches. Bring to a rolling boil and cook for 5 minutes, then lower the heat to a simmer. Cook for about 45 minutes, stirring occasionally, until the lentils are tender but still hold their shape. (If the water level gets too low, add more water as needed to keep them covered). Drain if needed and transfer to a bowl.

    Step 2

    Rinse the pot and heat over medium-high heat. When it’s hot, add the olive oil and onions; cook until they become translucent, and then add the minced ginger and garlic and cook until fragrant. Push the vegetables to the sides of the pot and add the tomato paste in the center. Cook, stirring constantly, until the paste deepens in color, then mix into the vegetables. Add the garam masala, cayenne pepper, cinnamon stick, broth, and cooked lentils. Simmer for 15 minutes, stirring frequently, to infuse the lentils with the spices. Then stir in the butter and cream and simmer for 2 minutes. Serve with a drizzle of olive oil and a sprinkle of cilantro if desired.

Black Lentils

Lentils belong to the broader family of legumes, which includes beans and dried peas. But unlike those others, lentils don’t need an overnight soak in water, so there’s less prep needed. Also available in red, green, and yellow, lentils are rich in protein, fiber, and iron, along with dozens of other nutrients. Because of their deep color, round shape, and tiny size, black lentils are often called caviar or beluga lentils. Black dal traditionally uses urad dal, a mung bean that’s not a true lentil, though it is a legume. However, black lentils—which you can find at specialty markets or online—work extremely well for dal and many other recipes.

Like other legumes, lentils keep best in a cool, dry cabinet, either in their original packaging or a tightly sealed glass container. They’re most flavorful (and take less time to cook) when used within a year of packaging. Before cooking, check them for any debris, like tiny stones, and rinse with cold water, then drain.

For Your Best Health: Sorbitol and The Liver 

For Your Best Health 

Sorbitol and The Liver 

Sweeteners such as aspartame, found in Equal packets, sucralose (Splenda), and sugar alcohols are widely promoted as healthier options than foods made with refined sugar (glucose). Many people turn to them hoping to reduce health risks linked to sugar and cut calories. But new scientific evidence is now calling that into question. Recent findings suggest that the sugar alcohol sorbitol in particular may not be as harmless as it is often assumed to be.

The findings come from a study published in Science Signaling that builds on years of research from the laboratory of Gary Patti, PhD, at Washington University in St. Louis into how fructose affects the liver and other organs. Dr. Patti, the Michael and Tana Powell Professor of Chemistry in Art & Sciences and a professor of genetics and medicine at WashU Medicine, has previously shown that fructose processed by the liver can be diverted in ways that fuel cancer cell growth. Other studies have linked fructose to steatotic liver disease, a condition that now affects about 30% of adults worldwide.

One of the most unexpected results of the new study is that sorbitol is essentially “one transformation away from fructose,” according to Dr. Patti. Because of this close relationship, sorbitol can trigger effects similar to those caused by fructose itself.

Using zebrafish as a model, Dr. Patti and his team showed that sorbitol, commonly found in low-calorie candies and gums and naturally present in stone fruits, can be produced inside the body. Enzymes in the gut can generate sorbitol, which is then transported to the liver and converted into fructose.

The team also discovered that the liver can receive fructose through multiple metabolic routes. Which pathway dominates depends on how much glucose and sorbitol a person consumes as well as the specific mix of bacteria living in their gut.

Most earlier studies of sorbitol metabolism focused on disease states such as diabetes, where high blood sugar leads to excess sorbitol production. Dr. Patti explained that sorbitol can also be created naturally in the gut after a meal, even in people without diabetes.

The enzyme responsible for making sorbitol does not bind easily to glucose, meaning glucose levels must rise significantly before the process begins. That is why sorbitol production has long been linked to diabetes. However, the zebrafish experiments showed that glucose levels in the intestine can become high enough after you eat to activate this pathway even under normal conditions. “It can be produced in the body at significant levels,” said Dr. Patti. “But if you have the right bacteria, turns out, it doesn’t matter.”

Certain Aeromonas bacterial strains are able to break down sorbitol and convert it into a harmless bacterial by-product. When these bacteria are present and functioning well, sorbitol is less likely to cause problems. “However, if you don’t have the right bacteria, that’s when it becomes problematic. Because in those conditions, sorbitol doesn’t get degraded, and as a result, it is passed on to the liver,” he said.

Once sorbitol reaches the liver, it is converted into a fructose derivative. This raises concerns about whether alternative sweeteners truly offer a safer option than table sugar, especially for people with diabetes and other metabolic disorders who often rely on products labeled as sugar-free.

At low levels, such as those typically found in whole fruits, gut bacteria are usually effective at clearing sorbitol. The trouble begins when the amount of sorbitol exceeds what these microbes can handle. This overload can happen when large amounts of glucose are consumed, leading to an increased production of sorbitol from glucose, or when the diet itself contains high levels of sorbitol. Even individuals with helpful bacteria may run into problems if their intake of glucose and sorbitol becomes too high, since the microbes can be overwhelmed.

Avoiding both sugar and sugar substitutes has become increasingly difficult, as many processed foods contain several forms of sweeteners at once. Dr. Patti said he was surprised to learn that his own favorite protein bar contained a significant amount of sorbitol.

Further research is needed to understand exactly how gut bacteria clear sorbitol. What is becoming clear, however, is that the long-held assumption that sugar alcohols, also known as polyols, are simply eliminated without harm may not be accurate. “We do absolutely see that sorbitol given to animals ends up in tissues all over the body,” he said. The overall message from the research is that replacing sugar is not as simple as it may seem. As Dr. Patti put it, “there is no free lunch” when it comes to sugar alternatives, and many metabolic pathways can ultimately lead back to liver dysfunction.

More Muscle, Younger Brain

New research shows that people who have more muscle and a lower visceral fat-to-muscle ratio tend to show signs of a younger biological brain age. This conclusion comes from a study recently presented at the annual meeting of the Radiological Society of North America. Visceral fat refers to the fat stored deep in the abdomen around key internal organs.

“Healthier bodies with more muscle mass and less hidden belly fat are more likely to have healthier, youthful brains,” said senior study author Cyrus Raji, MD, PhD, Associate Professor of Radiology and Neurology in the Department of Radiology at the Mallinckrodt Institute of Radiology at Washington University School of Medicine in St. Louis. “Better brain health, in turn, lowers the risk for future brain diseases, such as Alzheimer’s.”

Brain age is an estimate of how old the brain appears biologically, based on its structure as seen through an MRI. A whole-body MRI can track muscle mass, which serves as a marker for efforts to reduce frailty and strengthen overall health. Estimated brain age from structural scans may also shed light on risk factors for Alzheimer’s disease, including muscle loss.

“While it is commonly known that chronological aging translates to loss of muscle mass and increased hidden belly fat, this work shows that these health measures relate to brain aging itself,” Dr. Raji said. “It shows muscle and fat mass quantified in the body are key reflectors of brain health, as tracked with brain aging.”

Exercise for brain health

The study evaluated 1,164 healthy adults across four research sites using whole-body MRI. Participants had a mean chronological age of 55.17 years. Imaging included T1-weighted MRI sequences, which highlight fat as bright and fluid as dark, providing a clear view of muscle, fat, and brain tissue. An artificial intelligence (AI) algorithm measured total normalized muscle volume, visceral fat (hidden belly fat), subcutaneous fat (fat under the skin), and predicted brain age.

The data indicated that individuals with a higher visceral fat-to-muscle ratio had higher predicted brain age. Subcutaneous fat showed no meaningful association with how old the brain appeared. “The participants with more muscle tended to have younger-looking brains, while those with more hidden belly fat relative to their muscle had older-looking brains,” Dr. Raji said. “The fat just under the skin wasn’t related to brain aging. In short, more muscle and a lower visceral fat-to-muscle ratio were linked to a younger brain.”

Dr. Raji explained that focusing on building muscle and reducing visceral fat are realistic and actionable goals. Whole-body MRI and AI-based brain age estimates can offer clear benchmarks for programs designed to lower visceral fat while maintaining or increasing muscle. He also noted that the results highlight the close connection between physical health and brain health.

“This research has validated widely held hypotheses about the association between body composition biomarkers and brain health and provides a foundation for those biomarkers to be included in future trials of various metabolic interventions and treatments.”

Commonly prescribed glucagon-like peptide-1 (GLP-1) weight loss medications, including Ozempic, are effective at reducing body fat but may also contribute to muscle loss. Dr. Raji suggested that the study’s findings could help guide the development of next-generation therapies. These future treatments may aim to reduce visceral fat more than subcutaneous fat while protecting muscle mass.

“Losing fat—especially visceral fat—while preserving muscle volume would have the best benefit on brain aging and brain health based on insights from our work,” he said. “Thus, our study can inform future treatments by promoting research that quantifies MRI of body fat, muscle, and brain age, which can help determine the optimal dosing regimens for GLP-1s to achieve the best outcomes in body and brain health.”

Chicken Noodle Soup Recipe, Spotlight on Parsnips, Defatting Stock, High-fat Cheese and Dementia Risk plus Fitness Trends

So many of the recipes in The Olive Oil Hunter Newsletter and my e-cookbooks call for chicken stock. Yes, there are good-quality store brands, but nothing compares to homemade. The recipe is simple, and though stock requires monitoring over four hours, one batch can make enough for many recipes. It freezes perfectly, so you’ll always have some when you need it. And with a few more ingredients it becomes a delicious meal. Also in this edition, I’m sharing a surprising study on a potential benefit of high-fat cheese and the American College of Sports Medicine’s 2026 exercise trend report, with popular ways to stay fit and active.

Chicken Noodle Soup

  • Chicken Noodle Soup Chicken Noodle Soup

    Often called Jewish penicillin, homemade chicken soup is soothing whether you’re feeling under the weather or just want to shake off winter’s chill. This recipe yields at least 4 quarts of stock and most of the fixings for a chicken soup dinner—that’s why I use a whole bird and not just parts.

    Ingredients

    • 2 pounds large carrots, trimmed, peeled, and cut into large chunks
    • 6 large celery stalks, trimmed and cut into chunks
    • 1 large onion, peeled and quartered
    • 4 parsnips, trimmed, peeled, and cut into large chunks
    • 4 fresh flat-leaf parsley sprigs 
    • 4 fresh dill sprigs
    • 1 tablespoon coarse sea salt
    • 20 black peppercorns
    • One 4- or 5-pound chicken, quartered
    • One 12-ounce bag of egg noodles
    • Extra virgin olive oil for drizzling

    Directions

    Step 1

    Place the vegetables and herbs in a large stockpot and add water to cover them by about 4 inches. Add the salt and peppercorns and bring to a boil. Lower the heat, cover the pot with a lid, and cook at a low boil for 2 hours. 

    Step 2

    Add the chicken and cook for another 2 hours with the lid slightly ajar. The chicken should readily fall off the bones when done.

    Step 3

    Use tongs to transfer the carrots, parsnips, celery, and chicken to a large bowl; let cool slightly. Remove and discard the chicken skin and bones. Set the meat and vegetables aside. 

    Step 4

    Strain the broth to remove the herbs, any bits of onion, and peppercorns. Return 8 cups to the stockpot and keep warm. Let the rest cool to room temperature.

    Step 5

    Cook the egg noodles according to package directions. When ready, strain and divide among 6 soup bowls. Add some chicken and vegetables and ladle in broth. Drizzle with olive oil and serve.

    Step 6

    To store the rest of the stock: Ladle the room-temperature broth into freezer-safe containers. See Quick Kitchen Nugget in my weekly newsletter for removing fat if desired. Keep what you’ll use during the coming 7 to 10 days in the fridge and freeze the rest, labeling each lid with the contents and date.

    Yields 6 soup servings plus 6 to 8 quarts of stock

Healthy Ingredient Spotlight: Parsnips

Healthy Ingredient Spotlight

Parsnips

Parsnips and spices

Parsnips are the often-overlooked member of the carrot family, though they’re even sweeter than their orange cousin, especially when cooked—they add great richness to any broth.

High in fiber, parsnips are good sources of potassium and vitamins C and folate and have both anti-inflammatory and antifungal properties.

Look for parsnips that are firm and have a slightly off-white or ivory color—if they’ve turned yellow, they’re old. Store them in the fridge as you would carrots: in a crisper drawer wrapped in a cloth veggie bag or, if placed in a plastic bag, with a paper towel to soak up excess moisture.

To prep before using, cut off the tops and tips as needed. You can leave on the peel if it’s mostly unblemished or peel lightly as needed.

Defatting Stock 

Removing excess fat from stock doesn’t negatively affect its flavor; in fact, it can make the chicken taste more pronounced. The easiest way is to chill the stock in the fridge once it’s cooled to room temperature; wait a few hours or overnight, then use a slotted spoon to scoop out and discard the fat that has risen to the top and solidified. At this point, you can use the stock for another dish and/or freeze the containers for future use.

According to a study published in the December 2025 issue of Neurology, the medical journal of the American Academy of Neurology, people who eat higher amounts of full-fat cheese and cream may be less likely to develop dementia later in life. The findings point to a connection between these foods and dementia risk, but they do not prove that eating high-fat dairy prevents dementia. 

High-fat cheeses are defined as having more than 20% fat and include common types such as cheddar, Brie, and Gouda. High-fat creams generally contain 30% to 40% fat and include whipping cream, double cream, and clotted cream. In grocery stores, these products are often sold as “full-fat” or “regular” options.

“For decades, the debate over high-fat versus low-fat diets has shaped health advice, sometimes even categorizing cheese as an unhealthy food to limit,” said Emily Sonestedt, PhD, of Lund University in Sweden. “Our study found that some high-fat dairy products may actually lower the risk of dementia, challenging some long-held assumptions about fat and brain health.”

The research team analyzed dietary and health data from 27,670 adults in Sweden. At the beginning of the study, participants were an average of 58 years old. They were followed for about 25 years, during which time 3,208 people were diagnosed with dementia.

To track eating habits, participants recorded everything they consumed over the course of one week. They also answered questions about how frequently they ate specific foods during the previous several years and discussed their food preparation methods with researchers.

One part of the analysis focused on the daily consumption of high-fat cheese. Researchers compared people who ate 50 grams or more per day with those who ate less than 15 grams per day. Fifty grams of cheese is roughly equal to two slices of cheddar or about half a cup of shredded cheese and is approximately 1.8 ounces. A typical “recommended” serving of cheese is 1 ounce.

By the end of the study period, 10% of participants who ate higher amounts of high-fat cheese had developed dementia compared with 13% of those who ate less. After accounting for differences in age, sex, education, and overall diet quality, the researchers found that higher cheese consumption was associated with a 13% lower risk of dementia.

When specific forms of dementia were examined, the association was strongest for vascular dementia. People who consumed more high-fat cheese had a 29% lower risk of developing this type.

The researchers also observed a lower risk of Alzheimer’s disease among participants who ate more high-fat cheese, but this pattern was only seen in those who did not carry the APOE e4 gene variant, a genetic risk factor for Alzheimer’s.

The study also looked at the consumption of high-fat cream. Researchers compared people who consumed 20 or more grams per day with those who did not consume any. Twenty grams is about 1.4 tablespoons of heavy whipping cream. A recommended serving is about 1-2 tablespoons.

After making similar adjustments for health and lifestyle factors, the researchers found that the daily consumption of high-fat cream was linked to a 16% lower risk of dementia compared with consuming none.

Not all dairy foods showed the same relationship with dementia risk. The researchers found no association between dementia and the consumption of low-fat cheese, low-fat cream, high- or low-fat milk, butter, or fermented milk, which includes yogurt, kefir, and buttermilk. “These findings suggest that when it comes to brain health, not all dairy is equal,” said Dr. Sonestedt. “While eating more high-fat cheese and cream was linked to a reduced risk of dementia, other dairy products and low-fat alternatives did not show the same effect. More research is needed to confirm our study results and further explore whether consuming certain high-fat dairy truly offers some level of protection for the brain.”

One limitation of the study is that all participants lived in Sweden, which means the results may not apply to people in other countries. Dr. Sonestedt noted that dietary habits differ between regions. In Sweden, cheese is often eaten uncooked, while in the United States, cheese is frequently heated or eaten alongside meat. Because of these differences, she emphasized that similar studies should also be carried out in the United States.

Exercise: Trending Up

The American College of Sports Medicine (ACSM) recently published its latest fitness trends forecast based on a survey of 2,000 clinicians, researchers, and exercise professionals in the fitness industry in the ACSM Health & Fitness Journal. 

“We’ve seen dramatic changes in fitness trends over the last two decades, and this milestone gives us a long-term perspective of how the field has evolved and impacted health and fitness,” said Cayla R. McAvoy, PhD, ACSM-certified exercise physiologist, and lead author of 2026 ACSM Worldwide Fitness Trends: Future Directions of the Health and Fitness Industry. 

Survey findings offer both snapshots of current practices and insights into new priorities and growth areas across the health and fitness industry. Here are the top 10 trends for 2026. 

Wearable technology for tracking fitness - trending

1. Wearable technology. This continues to evolve, with advanced biosensors now capturing indicators such as fall or crash detection, heart rhythm, blood pressure, blood glucose, and skin temperature. These are particularly important for a wide demographic, ranging from patients in rehabilitation and fitness beginners to athletes and aging adults. 

“Wearable technology is a powerful tool to track fitness and health. While some data is useful and accurate, some metrics may be experimental or unreliable. Data is often useful for tracking patterns or changes over time, and certified exercise professionals can provide support on how to interpret the information.”—Sarah M. Camhi, PhD, FACSM, ACSM-EP

2. Fitness programs for older adults. The baby boomer generation includes 73 million Americans, all of whom will be over age 65 by 2030, intensifying the demand for age-appropriate evidence-based exercise options. According to the 2023 IHRSA US Health & Fitness Consumer Report, adults 65 and older were visiting gyms and studios more often than any other age group. 

“Physical activity is especially critical for older adults, as evidence consistently links regular exercise to the prevention and management of age-related conditions. Effective programs should be safe, enjoyable, and designed to enhance functional capacity in activities of daily living.”—Jennifer Turpin Stanfield, MA, ACSM-EP 

3. Exercise for weight management. This trend now includes increases in the use of obesity management medications such as GLP-1 RA. Exercise remains essential to long-term weight management by supporting lean mass, physical function, and metabolic health. Research shows that individuals who continue to exercise during pharmacologic treatment maintain greater fat loss and preserve more lean mass after stopping medication than those using medication alone. 

“Weight loss drugs may reduce muscle, which can harm health. Exercise may preserve muscle, boost strength, and improve physical function, but research is still ongoing.”—Dr. Camhi

4. Mobile exercise apps. These deliver on-demand, scheduled, live-streamed, or recorded workouts, offering users the convenience and flexibility to exercise anytime, anywhere. In 2024, more than 345 million people used fitness apps, generating more than 850 million downloads. Mobile apps can promote exercise adherence by offering convenience, structure, and self-monitoring tools. 

“The widespread use of smartphones and wearables has made mobile exercise apps highly accessible. These apps can track activity, support goal setting, provide on-demand classes, and facilitate social competition, making them a promising tool for promoting regular physical activity. Their overall effectiveness, however, depends on user engagement and program quality.”—Ms. Stanfield

5. Balance, flow, and core strength. This trend is a key component of a balanced fitness regimen, bridging movement quality and mental well-being. 

“Building strength in the core, improving balance, and engaging in mindfulness-based training are key to overall movement quality, injury prevention, and long-term health.”—Rachelle Reed, PhD, ACSM-EP  

“Pilates, yoga, and core training are resonating across generations. Their popularity reflects a broader industry shift toward longevity, holistic health, and mind-body integration.”—Dr. McAvoy

6. Exercise for mental health. Each year in the US, more than one in five adults report experiencing a mental health condition, reinforcing the importance of movement-based strategies that support emotional well-being. Certain formats may be especially appropriate: Resistance training reduces depressive symptoms, while low-intensity mindfulness-based formats such as yoga may offer additional value for stress reduction and emotional well-being. 

“Regular exercise is one of the most effective strategies we have to improve mental health, build emotional resilience, and enhance overall well-being. Its impact could rival some traditional clinical interventions and is certainly a strong supportive intervention. This holds true not only for the general population, but also for vulnerable groups such as pregnant women, youth, and older adults.”—A’Naja M. Newsome, PhD, ACSM-CEP, EIM 

7. Traditional strength training. Despite its benefits, fewer than 30% of US adults meet the recommended guidelines for muscle-strengthening activity. Resistance exercises use free weights such as barbells, dumbbells, and kettlebells to improve muscular strength, endurance, and function. Strength training plays a key role in maintaining bone density, metabolic health, and mobility across the lifespan.

“Strength training has been thoroughly researched and has gained significant popularity as one of the most effective fitness strategies due to its proven effectiveness, safety, and appeal to individuals of all ages and fitness levels.”—Alexios Batrakoulis, PhD, FACSM, ACSM-EP, ACSM-CPT 

8. Data-driven technology. More than 70% of wearable users have reported applying their output data to inform exercise or recovery strategies, and exercise professionals can use biofeedback to tailor intensity, assess readiness, and reduce the risk of overtraining. 

“Real-time physiological data, such as heart rate variability and sleep patterns, is shaping how people train and recover. These tools allow for more personalized adjustments that improve results and reduce injury risk. The key is translating complex numbers into clear, actionable guidance.”—Dr. McAvoy 

9. Adult recreation and sports clubs. This trend reflects growing interest in activities that combine fitness with fun, flexibility, and social connection outside traditional gym settings. By emphasizing enjoyment, camaraderie, and consistent participation, adult recreation and sports clubs may help reduce barriers to exercise and improve long-term adherence. 

“Pickleball, running clubs, and adult leagues are bringing people back to exercise in fun, social ways. These activities are about connection as much as they are about fitness.”—Dr. McAvoy

10. Functional fitness training. The “fitness is function” movement includes strength, power, mobility, and endurance and is designed to improve physical performance in real-world activities. Programs often emphasize movements that transfer directly to daily life or a sport. 

“Functional fitness marks a shift toward movement-based health, supporting independence in older adults, translating strength into everyday capability, and reinforcing the preventive power of exercise. It is not just a trend, but a cornerstone of exercise prescription.”—Dr. Newsome
