Your AI calorie-tracking app may be off by 345 calories
Popular AI-powered food apps may make calorie counting easier, but they may also leave out a surprisingly large part of the meal. Four apps underestimated calories and fat by about one-third when tested against carefully…
Why losing the wrong fat can trigger diabetes
Scientists discovered that damaged fat cells can become inflamed, lose their ability to store lipids, and eventually vanish, disrupting the body’s metabolism. The findings show that diabetes can result not only from exce…
Coffee may help shield the liver from fat, scarring, and cancer
A major long-term study linked coffee consumption with lower risks of cirrhosis, liver cancer, and death from liver disease. Coffee drinkers also showed healthier liver scans and blood protein patterns, with less fat, in…
Oral GLP-1 drugs may quiet the brain’s food craving circuit
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit. The finding could open new avenues for understanding food cravings and p…
AI helps Stanford scientists discover “natural Ozempic” without the usual side effects
Stanford Medicine researchers have discovered a naturally occurring molecule that may suppress appetite and reduce body weight much like Ozempic, but without several of its common side effects. The molecule, called BRP, …
Major genetic breakthrough reveals hidden causes of severe morning sickness in pregnancy
A massive genetic study has identified nine new genes linked to hyperemesis gravidarum, the most severe form of pregnancy sickness, bringing the total number of known risk genes to ten. The discoveries provide fresh insi…
A healthier global diet could cut farm emissions by 85%
A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume producti…

Popular sugar substitutes linked to faster brain aging
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or h…
Intermittent fasting helped people keep weight off for a year
A 12-week intermittent fasting program produced weight-loss benefits that were still visible a year later. Participants who ate within an eight-hour window maintained more weight loss than those who followed their usual …
Mediterranean diet may activate tiny proteins that protect the heart and brain
The Mediterranean diet may influence aging through tiny proteins produced inside the cell’s mitochondria. Older adults who followed the diet most closely had higher levels of humanin and SHMOOSE, which have been linked t…
Tiny plastics in drinking water may be making dangerous bacteria stronger
Tiny plastic particles in drinking water may be doing more than contaminating the environment. New research suggests nanoplastics can actually help harmful bacteria survive by strengthening the slimy biofilms they form i…
Scientists tested 39 sweeteners and found unexpected gut effects
A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently when combined with medi…
Chewing bubble gum after beetroot may help lower blood pressure
A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope t…
Eating chili peppers may raise the risk of one deadly cancer
A major review found that people who consumed the most chili peppers had a substantially higher risk of esophageal cancer, though the evidence was less clear for stomach and colorectal cancers. Researchers emphasize that…
Losing just 80 minutes of sleep a night could make you gain weight
Sleeping about an hour and 20 minutes less each night for six weeks caused participants to gain weight and spend more time inactive. Researchers found that even mild, realistic sleep loss, similar to what many adults exp…
Why are healthy young non-smokers developing lung cancer?
An unexpected study found that young non-smokers with healthier diets had higher rates of lung cancer, raising questions about whether pesticide exposure from conventionally grown produce could play a role. Researchers s…
Scientists discover the one nutrient beneficial parasites can't live without
A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-infla…
Scientists found a longevity diet that helped mice eat more and lose fat
Scientists found that a modified Mediterranean-style diet with low protein and just enough methionine helped mice live healthier lives while reducing body fat and frailty. Human data also linked lower animal protein inta…
A vitamin A discovery is changing what scientists know about vision
A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth. Instead of blue cone cells migrating away from the retina's center, the study found they transform in…
