The essential amino acid leucine can boost cellular energy production by protecting key proteins on mitochondria from being destroyed. The discovery reveals a new connection between nutrition and metabolism that could eventually lead to new ...

Scientists have linked a gut bacterial compound called ImP to greater Alzheimer's risk, harmful brain protein buildup, and faster cognitive decline. The finding raises the possibility that reducing ImP in the blood could one day help slow or prevent ...

Vitamin C may do more than support the immune system. In a phase 2 trial of people with precancerous or low risk blood cancers, daily vitamin C did not slow abnormal cell growth, but it was linked to favorable changes in inflammation and fewer ...

People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging. Berries and poultry were linked with healthier ...

More than half of 16,000 apparently healthy adults had signs of atherosclerosis, with arterial plaques already detectable in about 1 in 13 people ages 18 to 29. Researchers say directly imaging the arteries could reveal hidden cardiovascular disease ...

People with depression who dramatically cut ultra-processed foods experienced notable improvements in their symptoms in a small preliminary study. Researchers suspect healthier eating may benefit the brain partly by reducing gut damage and chronic .. ...

The Alzheimer's risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing promising new targets for ...

A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic readings by about 6.5 mmHg, potentially affecting ...

A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.

Mulberry compounds may reshape the gut microbiome in ways that support intestinal health and metabolism, with some combinations showing especially strong effects in animal studies. However, the results vary depending on the plant part and processing ...
