NEARLY HALF OF DEMENTIA CASES MAY BE PREVENTABLE A new study out of Lund University throws a spotlight on something many of us would rather not think about: dementia, and how our daily choices might shape our odds of ending up with it. The surprising part? Nearly half of dementia cases may be tied to risks you can actually change. The research tracked almost 500 people in their mid-sixties — all of them showing no signs of memory trouble at the start. Over four years, scientists watched for changes inside their brains, zeroing in on damage linked to vascular dementia and Alzheimer’s disease, the two biggest causes of cognitive decline. So what does this mean for you? Well, the usual suspects are back in the spotlight: smoking, high blood pressure, heart disease, and high cholesterol. Each of these was strongly linked to damage in the brain’s white matter — the network of nerve fibers that keeps everything running smoothly. In short, those habits don’t just mess with your heart; t...

EXERCISING FOR OPTIMAL HEART PROTECTION You’ve probably heard the advice: get at least 150 minutes of moderate-to-vigorous exercise each week to keep your heart healthy. But what if that bar is actually set too low? A large new study published in the British Journal of Sports Medicine suggests you might need far more movement to make a real dent in your risk for heart attack and stroke [BMJ, 2026]. Aiming Higher: Is 150 Minutes Enough? The research, based on data from over 17,000 adults in the UK Biobank, found that the standard 150 minutes offers only a modest 8–9% reduction in cardiovascular risk. To see a more dramatic drop—a risk reduction of over 30%—participants needed to rack up 560 to 610 minutes per week of moderate-to-vigorous activity, such as brisk walking, running, or cycling. That’s nearly 9 to 10 hours every week, or about an hour and 20 minutes a day. Only about 12% of people in the study met this higher target, meaning the vast majority aren’t getting the full pro...

G REEK YOGURT: A NUTRITIONAL POWERHOUSE Greek yogurt has gone from niche health food to fridge staple in the last decade, and it’s not just because it tastes good. Research shows Greek yogurt packs a nutritional punch that regular yogurt—and most other dairy products—can’t quite match [Frontiers in Nutrition]. Why Greek Yogurt Stands Out The secret is in the straining. Greek yogurt is made by removing much of the whey, which gives it that signature thick texture and a protein content that can be double or even two-and-a-half times higher than standard yogurt. This high protein load isn’t just for gym-goers; it helps keep you full, supports muscle growth, and aids recovery after exercise. One study even found that eating fat-free plain Greek yogurt as part of a high-impact workout routine led to bigger gains in strength, muscle thickness, and body composition than some other dairy options over 12 weeks [Frontiers in Nutrition]. What’s in a Serving? A typical 100-gram scoop of Gree...

CHILDHOOD OBESITY THEORY CHALLENGED For four decades, pediatricians have feared the so-called "adiposity rebound"—a rise in body mass index (BMI) around age six that was supposed to signal kids were gaining unhealthy fat. But new research, presented at the 2026 European Congress on Obesity by Professor Andrew Agbaje of the University of Eastern Finland, suggests we may have gotten it all wrong (Agbaje et al., 2026). A Misread Signal The idea, which dates back to a 1984 paper by Marie Françoise Rolland-Cachera (Rolland-Cachera et al., 1984), is simple: after BMI drops from infancy to early childhood, it rises again—supposedly due to increased body fat. Doctors have used the timing of this BMI rise as an early warning for future obesity, sometimes even recommending dietary interventions to try to delay the rebound. But Agbaje's work calls this logic into question. Using a more precise measure of body fat—the waist-to-height ratio (WHtR)—he found that while BMI does dip an...

ARGININE MAY HELP PREVENT CANCER AND VIRAL INFECTIONS Could boosting a single amino acid help your body spot threats like cancer and viral infections? New research suggests it just might. Scientists at Rockefeller University have found that low levels of arginine—a common amino acid found in many protein-rich foods—may allow cancer cells and viruses to evade detection by the immune system. Their findings, published in Cell , reveal that supplementing with arginine could strengthen immune defenses and potentially change how we approach certain diseases ( Rockefeller University, 2026 ). Arginine: More Than Just a Building Block Arginine isn’t just another nutrient. It’s an amino acid your body produces naturally and gets from foods like meat, dairy, and nuts. It helps cells build the proteins they need to function. But when arginine levels drop, things can go wrong. For example, colon cancer has been linked to abnormally low arginine ( Wu et al., 2026 ). Dr. Sohail Tavazoie and hi...

NAD: A POWER BROKER FOR YOUR HEALTH Nicotinamide adenine dinucleotide, or NAD, is a powerhouse molecule present in every living cell, essential for life's chemistry. At its heart, NAD acts as a coenzyme, a helper molecule that enables enzymes to drive vital chemical reactions. It toggles between two forms—NAD⁺ (oxidized) and NADH (reduced)—constantly cycling as it participates in crucial metabolic work. NAD's main gig is facilitating redox reactions, which involve the transfer of electrons between molecules. This electron shuffle is how your body turns food into energy. When you break down carbs, fats, and proteins, NAD⁺ grabs electrons and becomes NADH. Then, NADH hands off those electrons to the cell's energy factories, helping produce ATP, the molecule cells use as fuel (Cleveland Clinic)[ https://my.clevelandclinic.org/health/body/nad-nicotinamide-adenine-dinucleotide ]. But NAD⁺ is more than just an energy courier. It's also a key player in regulating cellular he...
