We all know that milk is good for health, especially for our bones and muscles. Now a new study has suggested that it could be important for one's brain health as well. Researchers at University of Kansas (KU) Medical Center have found a possible correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione in the brain in older, healthy adults.

During the study, researchers asked the 60 participants about their diets in the days leading up to high-tech brain scans, which they used to monitor levels of glutathione which is a powerful antioxidant in the brain. They found that participants who had indicated they had drunk milk recently had higher levels of glutathione in their brains.

Researchers said, "This is important because glutathione could help stave off oxidative stress and the resulting damage caused by reactive chemical compounds produced during the normal metabolic process in the brain. Oxidative stress is known to be associated with a number of different diseases and conditions, including Alzheimer's disease, Parkinson's disease and many other conditions."
