Double Strawberry Mousse Recipe, Spotlight on Strawberries, Buying and Storing Strawberries, The Impact of Carbs and Lowering Your Disease Risk

As farmers’ markets pop up around the country, look for fresh strawberries ripe for turning into luscious desserts. This mousse is sinfully rich, yet so easy to whip up. Whole foods are crucial to a healthy diet, and the first study I’m sharing shows what happens when we eat too many refined carbs. The second sheds new light on the importance of exercise intensity.

Double Strawberry Mousse

  • Double strawberry mousse Double Strawberry Mousse

    This dessert features strawberries in the mousse and in the topping. The berries are first macerated — tossed with sugar and allowed to sit — to draw out and intensify the fruit’s flavors.

    Ingredients

    • 1 1/2 pounds fresh strawberries 
    • 2 tablespoons granulated sugar
    • 1 tablespoon extra virgin olive oil
    • 1 1/2 cups heavy cream
    • Optional: 1/3 cup confectioners’ sugar 

    Directions

    Step 1

    Hull the strawberries, then dice them and place in a large glass bowl. Add the granulated sugar and toss well; set aside for 30 minutes. Drizzle on the olive oil and mix well. Reserve 1/2 cup of the berries, cover, and refrigerate. Place the rest in a food processor and run the machine until the berries are puréed. You should have about 1-1/2 cups.

    Step 2

    Place the heavy cream in the bowl of a stand mixer or a large bowl with a hand mixer. Beat on low speed, then gradually increase to high. Whip until the cream reaches medium (not stiff) peaks, then use a spatula to fold in the strawberry purée. Taste and add the confectioners’ sugar if desired. Serve right away or refrigerate the mousse in the mixing bowl for up to 4 hours — it will firm up more as it chills.

    Step 3

    To serve, spoon equal portions of the mousse into 8 goblets or bowls and garnish with equal amounts of the reserved berries.

Strawberries

Strawberries are packed with essential vitamins, minerals, fiber, and phytochemicals, including anthocyanins, which give them their vivid hue, and other antioxidants to protect against oxidative stress. A study published in the journal Nutrition, Metabolism and Cardiovascular Diseases found that eating about 2 cups of strawberries a day improves heart health and cognition in older adults. 

There is one caveat. According to the Environmental Working Group, strawberries have high levels of pesticides including “forever chemicals” (PFAS) and fungicides—they’re often ranked at the top of the Group’s “Dirty Dozen” list of most affected fruits and vegetables. Because of this, buy organic whenever you can to reduce your exposure to substances linked to cancer, hormone disruption, and brain toxicity.

Buying and Storing Strawberries 

Look for bright red strawberries, with bright green caps, and free of moldy spots. If you’re buying berries packed in plastic boxes, be sure to turn them over and check the underside. At home, refrigerate your berries if not using right away, but don’t wash them ahead of time, which could increase the risk for mold. Store packaged berries upside down — this puts the ventilation slots on top, allowing better air circulation. 

For Your Best Health: The Impact of Carbs

The Impact of Carbs

Bread has long been a dietary cornerstone, sustaining societies for generations. It is deeply woven into everyday life. Carbohydrates such as bread, rice, and noodles are consumed daily around the world, yet their role in obesity and metabolism has not been explored thoroughly. With obesity rates continuing to climb, researchers are beginning to question whether this reliance on staple carbohydrates still makes sense in modern diets. While many people believe that “bread makes you gain weight” or that “carbohydrates should be limited,” it has been unclear whether the issue lies in the foods themselves or in how people choose and consume them.

To better understand these questions, a research team led by Professor Shigenobu Matsumura at Osaka’s Graduate School of Human Life and Ecology in Japan studied how carbohydrates influence eating behavior and metabolism in mice. The researchers examined whether mice preferred foods like wheat, bread, and rice over standard chow, and how these choices affected body weight and energy use. The animals were divided into several feeding groups, including Chow, Chow + Bread, Chow + Wheat flour, Chow + Rice flour, High-fat diet (HFD) + Chow, and HFD + Wheat flour. The team tracked changes in body weight, energy expenditure, blood metabolites, and liver gene expression.

The findings showed that mice strongly favored carbohydrate-rich foods and stopped eating their standard chow altogether. Even though their total calorie intake did not increase significantly, both body weight and fat mass went up. Mice that consumed rice flour gained weight in a similar way to those that ate wheat flour. In contrast, mice given a High-fat diet (HFD) + Wheat flour gained less weight than those on a High-fat diet (HFD) + Chow. “These findings suggest that weight gain may not be due to wheat-specific effects, but rather to a strong preference for carbohydrates and the associated metabolic changes,” said Professor Matsumura.

Further analysis revealed higher levels of fatty acids in the blood and lower levels of essential amino acids. In the liver, fat accumulation increased, along with the activity of genes linked to fatty acid production and lipid transport. When wheat flour was removed from the diet, both body weight and metabolic abnormalities improved quickly. This suggests that moving away from a wheat-heavy diet and toward a more balanced one may help regulate body weight more effectively.

“Going forward, we plan to shift our research focus to humans to verify the extent to which the metabolic changes identified in this study apply to actual dietary habits,” said Professor Matsumura. “We also intend to investigate how factors such as whole grains, unrefined grains, and foods rich in dietary fiber, as well as their combinations with proteins and fats, food processing methods, and timing of consumption, affect metabolic responses to carbohydrate intake. In the future, we hope this will serve as a scientific foundation for achieving a balance between ‘taste’ and ‘health’ in the fields of nutritional guidance, food education, and food development.”

Lowering Your Disease Risk

Just a few minutes of getting out of breath each day could significantly cut your risk of major diseases including heart disease, dementia, and diabetes. A large study of nearly 100,000 people published in the European Heart Journal found that it’s not just how much you move, but how intensely you move that matters. Short bursts of vigorous activity—like rushing for a bus or climbing stairs quickly—were linked to striking reductions in disease risk, especially for inflammatory conditions like arthritis, serious cardiovascular problems such as heart attack and stroke, and dementia.

To explore this connection, researchers compared participants’ overall physical activity levels with how much of that activity was vigorous, then tracked their risk of developing eight major diseases over time. The study was led by an international team that included Professor Minxue Shen from the Xiangya School of Public Health at Central South University in Hunan, China. “We know that physical activity reduces the risk of chronic disease and premature death, and there is growing evidence that vigorous activity provides greater health benefits per minute than moderate activity,” he said. “But questions remain about the importance of intense activity versus total physical activity. For example, if two people do the same total amount of activity, does the person who exercises more vigorously gain greater health benefits? And if someone has limited time, should they focus on exercising harder rather than longer?”

Participants, all part of the UK Biobank study, wore wrist-based accelerometers for one week. These devices captured detailed movement patterns, including short bursts of vigorous activity that people might not remember or report. Researchers used this data to calculate both total activity and the share that was intense enough to cause breathlessness.

The team then compared these measurements with participants’ likelihood of dying or developing eight serious conditions over the next seven years: major cardiovascular disease, irregular heartbeat, type 2 diabetes, immune-mediated inflammatory diseases, liver disease, chronic respiratory diseases, chronic kidney disease, and dementia.

The results showed that people who devoted a larger portion of their activity to vigorous movement had much lower risks across all conditions studied. Compared with those who did no vigorous activity, individuals with the highest levels saw a 63% lower risk of dementia, a 60% lower risk of type 2 diabetes, and a 46% lower risk of death. These benefits were observed even when the total time spent on vigorous activity was relatively small.

Couple working out and sweating

The researchers also found that intensity played a larger role for certain diseases. For inflammatory conditions such as arthritis and psoriasis, intensity appeared to be the key factor in lowering risk. In contrast, for diseases like diabetes and chronic liver disease, both how long people were active and how hard they exercised were important.

“Vigorous physical activity appears to trigger specific responses in the body that lower-intensity activity cannot fully replicate,” Professor Shen said. “During vigorous physical activity — the kind that makes you feel out of breath — your body responds in powerful ways. Your heart pumps more efficiently, your blood vessels become more flexible, and your body improves its ability to use oxygen. Vigorous activity also appears to reduce inflammation. This may help explain why we saw strong associations with inflammatory conditions such as psoriasis and arthritis. It may also stimulate chemicals in the brain that help keep brain cells healthy, which could help explain the lower risk of dementia.

“Our findings suggest that making some of your physical activity vigorous can provide substantial health benefits. This doesn’t require going to the gym. Adding short bursts of activity that make you slightly breathless into daily life, like taking the stairs quickly, walking fast between errands, or playing actively with children, can make a real difference. Even 15 to 20 minutes per week of this kind of effort — just a few minutes a day — was linked to meaningful health benefits.

“Current guidelines generally focus on the amount of time spent being active per week. Our findings suggest that the composition of that activity matters and matters differently depending on which diseases you’re trying to prevent. This could open the door to more personalized physical activity recommendations based on an individual’s specific health risks,” he said, adding, “Vigorous activity may not be safe for everyone, especially older adults or people with certain medical conditions. For them, any increase in movement is still beneficial, and activity should be tailored to the individual.”

Halloumi Skewers Recipe, Spotlight on Bell Peppers, Safe Grill Cleaning, Extra Virgin Olive Oil for Brain Boosts and Meditation to Rewire your Brain

Members of the Fresh-Pressed Olive Oil Club know how much of a halloumi cheese fan I am. This recipe uses the salty, firm Cypriot cheese as part of grilled skewers that will please meat eaters and non-meat eaters alike. I’m also thrilled to share two fascinating pieces of research concerning brain health: the roles of extra virgin olive oil and meditation.

Halloumi Skewers

  • Grilled Halloumi Skewers Halloumi Skewers

    Besides its great taste, halloumi holds its shape well under high heat and, unlike beef, chicken, and other proteins, it takes only as long as the vegetables to grill so all the ingredients on your skewers will be done at the same time.

    Ingredients

    For the marinade:

    • 4 garlic cloves
    • 1/4 cup fresh herbs such as basil, oregano, and flat-leaf parsley
    • 2 tablespoons balsamic vinegar of Modena such as Condimento Barili Exclusivi 
    • 1/4 cup extra virgin olive oil
    • 1/2 teaspoon fine sea salt
    • 1/4 teaspoon freshly ground black pepper

    For the skewers:

    • 1 pound halloumi cheese block, cut into 1-1/2-inch cubes 
    • 1 medium zucchini, cut into 3/4-inch rounds
    • 1 medium red onion, peeled and cut into 6 wedges 
    • 2 large bell peppers, any colors, cut into 1-1/2-inch squares
    • 8 cremini or white mushrooms, cleaned as needed

    Directions

    Step 1

    Place the garlic and herbs in a mini chopper and process until finely chopped. Add the vinegar, olive oil, salt, and pepper and process until smooth. 

    Step 2

    Place the cheese and all the vegetables in a large bowl and add the marinade; toss well. Let marinate for 20 minutes, then shake off excess marinade and thread equal amounts onto four 12-inch skewers (if using wooden skewers, soak in water for 30 minutes first).

    Step 3

    Grill over medium-high heat, turning the skewers every 2 to 3 minutes to char all four sides (8 to 12 minutes total). Remove from the grill as soon as you see a light char.

Healthy Ingredient Spotlight: The Colors of Bell Peppers

Healthy Ingredient Spotlight

The Colors of Bell Peppers

Bell peppers are a great source of vitamin C (two or three times as much as an orange) plus vitamins B6, K, A, and E along with minerals and antioxidants. They come in a rainbow of colors, determined by the variety and amount of time a bell pepper spends on the plant.

Green bell peppers appear first and are the least ripe and least sweet. As they mature, they usually turn another color, such as yellow, orange, or red. Nutrient content and taste vary among bell pepper varieties. The phytonutrients lutein and zeaxanthin, important for eye health, are found in green bell peppers. Violaxanthin, a carotenoid, is found in yellow bell peppers. Capsanthin makes fully mature bell peppers red. Red bell peppers are the most nutrient-dense and also contain lycopene and beta-carotene. 

When it comes to bell peppers, the advice is the same as with vegetables (and fruits): Eat the rainbow to get the max benefits.

Safe Grill Cleaning

Recently, over 13 million grill brushes from Nexgrill and Weber were recalled because their small wire bristles can break off, stick to grill grates, and lodge in food, posing serious injury risks if swallowed. The Consumer Product Safety Commission recommends people stop using these brushes immediately and contact the manufacturers for a refund or replacement. Weber, for instance, was offering a replacement nylon bristle brush. 

How to clean your grill grates safely? A great way is to make a thick paste of baking soda and dish liquid. Smear it over the grates, then use a crumpled ball of aluminum foil to go over each groove. Thoroughly rinse and dry. To properly season the grates, finish with a light coating of olive oil dabbed on a paper towel.

Extra Virgin Olive Oil for Brain Boosts

Extra virgin olive oil, or EVOO, has long been a cornerstone of the Mediterranean diet, known for supporting heart and metabolic health. Now, new research suggests it may also help protect the brain. Scientists from the Human Nutrition Unit at the Universitat Rovira i Virgili (URV), the Pere Virgili Health Research Institute (IISPV), and CIBEROBN have found that its benefits could extend beyond the body to the mind, working through the gut microbiome to support cognitive function.

“This is the first prospective study in humans to specifically analyze the role of olive oil in the interaction between gut microbiota and cognitive function,” explains Jiaqi Ni, PhD, first author of the article and researcher at the URV’s Department of Biochemistry and Biotechnology.

The research followed 656 adults between the ages of 55 and 75 who were overweight or obese and had metabolic syndrome — a set of risk factors that increase the likelihood of developing cardiovascular disease. Over a two-year period, as part of the PREDIMED-Plus project, scientists tracked participants’ diets, including their intake of virgin and refined olive oil, along with detailed analyses of their gut microbiota. They also monitored changes in cognitive performance over time.

The findings showed clear differences depending on the type of olive oil consumed. Participants who regularly used virgin olive oil experienced improvements in cognitive function and had a more diverse gut microbiota, which is widely considered a sign of better intestinal and metabolic health. In contrast, those who consumed refined olive oil tended to show a decline in microbiota diversity over time. Researchers also identified a specific group of gut bacteria, known as Adlercreutzia, that may be tied to these benefits. Its presence could serve as an indicator of the positive relationship between virgin olive oil consumption and preserved cognitive function. These results suggest that part of the oil’s brain-supporting effect may come from how it reshapes the gut microbiome.

The difference between extra virgin and refined olive oil largely comes down to how they are produced. Extra virgin olive oil is obtained using mechanical methods, which help preserve its natural compounds. Refined olive oil, on the other hand, undergoes industrial processing to remove impurities. While this refining process improves shelf life, it also reduces beneficial components such as antioxidants, polyphenols, vitamins, and other bioactive substances. 

Jordi Salas-Salvadó, MD, PhD, principal investigator of the study, emphasized the importance of choosing high-quality fats: “This research reinforces the idea that the quality of the fat we consume is as important as the quantity; extra virgin olive oil not only protects the heart, but can also help preserve the brain during aging.” 

Two of the other researchers involved, URV professor Nancy Babio-Sánchez, PhD, and Stephanie Nishi, PhD, now a professor with the Toronto Metropolitan University (Canada), highlighted the broader implications of the findings as populations continue to age: “At a time when cases of cognitive decline and dementia are on the rise, our findings drive home the importance of improving diet quality, and in particular prioritizing extra virgin olive oil over other refined versions as an effective, simple, and accessible strategy for protecting brain health.”

Meditation to Rewire your Brain

Researchers at the University of California San Diego report that a weeklong program combining meditation and other mind-body techniques can quickly produce measurable changes in both brain activity and blood biology. The study found that these practices activated natural pathways involved in brain flexibility, metabolism, immune function, and pain relief. Surprisingly, the experience mirrored psychedelic-like brain states—without any drugs involved. Published in Communications Biology, the findings offer new evidence that mental practices can influence physical health in significant ways.

Meditation and similar approaches have been used for thousands of years to support well-being, but scientists have struggled to explain exactly how they affect the body. This new research, part of a large initiative funded by the InnerScience Research Fund, is the first to systematically measure the combined biological effects of multiple mind-body techniques delivered over a short time.

“We’ve known for years that practices like meditation can influence health, but what’s striking is that combining multiple mind-body practices into a single retreat produced changes across so many biological systems that we could measure directly in the brain and blood,” said senior study author Hemal H. Patel, PhD, professor of anesthesiology at UC San Diego School of Medicine and research career scientist at the Veterans Affairs San Diego Healthcare System. “This isn’t about just stress relief or relaxation; this is about fundamentally changing how the brain engages with reality and quantifying these changes biologically.”

The study followed 20 healthy adults who took part in a 7-day residential retreat led by neuroscience educator and author Joe Dispenza, DC. Participants attended lectures and completed about 33 hours of guided meditation along with group-based healing activities.

These sessions used an “open-label placebo” approach, meaning participants were aware that some practices were presented as placebos. Even so, such interventions can still produce real effects through expectation, shared experience, and social connection.

Before and after the retreat, researchers used functional magnetic resonance imaging (fMRI) to monitor brain activity. Blood samples were also analyzed to track changes in metabolism, immune function, and other biological markers. After the retreat, several notable changes were detected:

  • Brain network changes: Activity decreased in regions linked to internal mental chatter, suggesting more efficient brain function.
  • Enhanced neuroplasticity: Blood plasma collected after the retreat encouraged lab-grown neurons to extend and form new connections.
  • Metabolic shifts: Cells exposed to post-retreat plasma showed increased glycolytic (sugar-burning) metabolism, indicating improved metabolic flexibility.
  • Natural pain relief: Levels of endogenous opioids, the body’s natural painkillers, rose following the retreat.
  • Immune activation: Both inflammatory and anti-inflammatory signals increased, pointing to a balanced and adaptive immune response.
  • Gene and molecular signaling changes: Small RNA and gene activity shifted in ways linked to brain-related biological pathways.

Participants also completed the Mystical Experience Questionnaire (MEQ-30), which measures feelings such as unity, transcendence, and altered awareness during meditation. Scores increased from an average of 2.37 before the retreat to 3.02 afterward. Those who reported stronger mystical experiences also showed more pronounced biological changes, including greater coordination between different brain regions. This suggests that deeper subjective experiences may be tied to measurable changes in brain function.

The researchers found that the brain activity patterns observed after the retreat closely resembled those previously linked to psychedelic substances. “We’re seeing the same mystical experiences and neural connectivity patterns that typically require psilocybin, now achieved through meditation practice alone,” added Patel. “Seeing both central nervous system changes in brain scans and systemic changes in blood chemistry underscores that these mind-body practices are acting on a whole-body scale.”

The findings help explain how non-drug approaches like meditation may support overall health. By boosting neuroplasticity and influencing immune activity, these practices could improve emotional regulation, stress resilience, and mental well-being. The increase in natural pain-relief chemicals also points to potential applications for managing chronic pain.

Future studies will explore whether similar programs could help people with chronic pain, mood disorders, or immune-related conditions. The team also plans to examine how different elements of the retreat, including meditation, reconceptualization, and open-label placebo healing, contribute individually and together. Another key question is how long these biological changes last and whether repeated practice can strengthen or maintain them.

“This study shows that our minds and bodies are deeply interconnected — what we believe, how we focus our attention, and the practices we participate in can leave measurable fingerprints on our biology,” said first author Alex Jinich-Diamant, a doctoral student in the Departments of Cognitive Science and Anesthesiology at UC San Diego. “It’s an exciting step toward understanding how conscious experience and physical health are intertwined, and how we might harness that connection to promote well-being in new ways.”
