A sweeping review of more than 350 studies suggests that the protein boom may be overselling what many people actually need. Eating less protein appears to improve metabolism, reduce inflammation and cellular damage, and activate pathways linked to . ...

Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to ...

A daily avocado may help lower heart disease risk in adults with obesity by reducing the number of LDL particles circulating in the blood. After six months, participants who ate an avocado each day experienced a decline associated with an estimated 4 ...

Scientists have identified an immune response that may explain why statins cause muscle pain, weakness, and exercise intolerance in some people. The finding could eventually lead to treatments that protect muscles while preserving the drugs' ...

Blood cancers that eventually worsen may carry detectable genetic warning signs years before patients develop serious symptoms. The findings could lead to earlier intervention while also helping doctors distinguish true cancer from harmless age ...

A new report suggests that blood pressure may be controlled more effectively by increasing potassium while also cutting sodium. Potassium-rich foods can help balance sodium's effects, but most people consume far less potassium than recommended.

A gene involved in the brain's overnight cleaning system may change how strongly poor sleep affects Alzheimer's-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.

New research challenges the decades-old idea that children experience an "adiposity rebound" when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The ...

A person's sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected "brain age" was tied to a ...

Researchers have uncovered a possible biological pathway connecting obesity to Alzheimer's disease. Obesity appears to raise levels of certain fat molecules that can travel to the brain, disrupt its immune defenses, and promote harmful amyloid ...
