Researchers have uncovered how a protein called MRAP2 acts as a key regulator of hunger. It helps move the appetite receptor MC4R to the cell’s surface, allowing it to send stronger “stop eating” signals. The discovery offers new hope for ...
A massive new study combining observational and genetic data overturns the long-held belief that light drinking protects the brain. Researchers found that dementia risk rises in direct proportion to alcohol consumption, with no safe level ...
Scientists discovered that high-fat junk food disrupts memory circuits in the brain almost immediately. Within just four days, neurons in the hippocampus became overactive, impairing memory. Restoring glucose calmed the neurons, showing that ...
Daily cocoa extract supplements reduced key inflammation markers in older adults, pointing to a role in protecting the heart. The findings reinforce the value of flavanol-rich, plant-based foods for healthier ...
For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain immune cells can become clogged with fat, leaving ...
Researchers have shown that a green-Mediterranean diet can help slow brain aging. By analyzing data from the DIRECT PLUS trial, scientists found reduced levels of proteins tied to faster brain decline among those consuming green tea and Mankai. The ...
Plastic particles from everyday items like Styrofoam cups and take-out containers are finding their way into the brain, where they may trigger Alzheimer’s-like symptoms. New research shows that mice carrying the Alzheimer’s-linked APOE4 gene who ...
Some people taking Ozempic, Wegovy, or Mounjaro notice that food suddenly tastes sweeter or saltier, and this subtle shift in flavor perception appears tied to reduced appetite and stronger feelings ...
People taking semaglutide report far fewer obsessive thoughts about food, with cravings dropping sharply and mental health improving. This new research hints the drug may offer freedom from the constant distraction of food ...
What we eat as we age may determine how many chronic illnesses we face later in life. A 15-year study of more than 2,400 older adults reveals that diets rich in vegetables, whole grains, nuts, and healthy fats slow the accumulation of diseases like ...
Scientists discovered seven molecules in the blood linked to excessive daytime sleepiness, a condition that affects one in three Americans and raises the risk of heart disease, obesity, and diabetes. The study highlights the role of both diet and ...
A large Brazilian study following more than 12,000 middle-aged adults found that those consuming the most artificial sweeteners—commonly found in diet sodas, flavored waters, and processed snacks—experienced significantly faster declines in ...
