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.

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.

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
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…

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.

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.

Vegan diet beats Mediterranean for weight loss even with potatoes and grains
Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even “unhealthy” ones, was strongly associated with greater weight loss.

Ultra-processed foods may harm health because of what they contain but also how they are manufactured to promote overconsumption and maximize profits.

Low-fat vegan diet can reduce an individual's greenhouse gas emissions by 51%
A low-fat vegan diet is associated with a significant reduction in greenhouse gas emissions (GHGE) and cumulative energy demand (CED) compared to the Standard American Diet, according to research by the Physicians Committee for Responsible Medicine published in JAMA Network Open.
