Q&A: How changing your diet could help save the world
For many of us, the holiday season can mean delightful overeating, followed by recriminatory New Year's resolutions.

Eating more vitamin C can physically change your skin #nutrition

Eating more vitamin C can physically change your skin
Vitamin C doesn’t just belong in skincare products—it works even better when you eat it. Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal. People who ate two vitamin C–packed kiwifruit daily showed thicker, healthier skin. The findings suggest glowing skin really does start from within.

These common food preservatives may be linked to cancer
A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives—commonly found in processed foods and drinks—is linked to a modestly higher cancer risk. While many preservatives showed no association, several widely used ones, including potassium sorbate, sulfites, sodium nitrite, and potassium nitrate, were tied to increased risks of overall cancer and specific types such as breast and prostate cancer.

Pecans found to improve cholesterol and boost heart health #nutrition

Pecans found to improve cholesterol and boost heart health
A sweeping new scientific review suggests that pecans — America’s native nut — may pack more heart power than many people realize. After analyzing over 20 years of research, scientists found consistent evidence that eating pecans can improve key markers of cardiovascular health, including total cholesterol and “bad” LDL cholesterol, while also supporting antioxidant defenses.

Ultra-processed foods linked to 47% higher risk of heart attack and stroke #nutrition

Ultra-processed foods linked to 47% higher risk of heart attack and stroke
Ultra-processed foods are everywhere in the American diet, and researchers are finding alarming consequences. Using national health data, scientists found that adults with the highest intake of these foods had a 47% higher risk of heart attack or stroke. The results held even after accounting for age, smoking, and income. Experts say reducing ultra-processed foods could become as important to public health as cutting back on tobacco once was.

Ultra-processed foods damage health in ways that calories don’t explain, new study says #nutrition

Ultra-processed foods damage health in ways that calories don't explain, new study says
Ultra-processed foods may harm health because of what they contain but also how they are manufactured to promote overconsumption and maximize profits.

This simple diet shift cut 330 calories a day without smaller meals #nutrition

This simple diet shift cut 330 calories a day without smaller meals
People who switch to a fully unprocessed diet don’t just eat differently—they eat smarter. Research from the University of Bristol shows that when people avoid ultra-processed foods, they naturally pile their plates with fruits and vegetables, eating over 50% more food by weight while still consuming hundreds fewer calories each day. This happens because whole foods trigger a kind of built-in “nutritional intelligence,” nudging people toward nutrient-rich, lower-calorie options.

Why ultra-processed foods make teens eat more when they aren’t hungry #nutrition

Why ultra-processed foods make teens eat more when they aren’t hungry
A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed diet. Because eating without hunger predicts future weight gain, these findings hint at a heightened vulnerability during late adolescence.

A quiet change in everyday foods could save thousands of lives #nutrition

A quiet change in everyday foods could save thousands of lives
Lowering salt in everyday foods could quietly save lives. Researchers found that modest sodium reductions in bread, packaged foods, and takeout meals could significantly reduce heart disease and stroke rates in France and the U.K. The key advantage is that people would not need to alter their eating habits at all. Small changes to the food supply could deliver large, long-term health benefits.

MIT study shows high-fat diets give liver cancer a dangerous head start #nutrition

MIT study shows high-fat diets give liver cancer a dangerous head start
A high-fat diet does more than overload the liver with fat. New research from MIT shows that prolonged exposure to fatty foods can push liver cells into a survival mode that quietly raises the risk of cancer. Faced with ongoing metabolic stress, these cells abandon their normal roles and revert to a more primitive state that helps them endure harsh conditions. Over time, that shift leaves the liver less functional and far more vulnerable to tumor formation, helping explain why fatty liver disea…
