As people age their brains undergo what is called “oxidative stress” from normal metabolism. This can produce the equivalent of rust in the brain with increased risk of degenerative brain diseases like Alzheimer’s and Parkinson’s. Although supplement producers charge high prices for the over-the-counter pills which they claim will protect your brain from bio-chemical rusting, their claims have not been proven. Why not eat or drink natural foods that have been proven to get anti-oxidant molecules into your brain? In the Feb. 3, 2015 issue of the The American Journal of Clinical Nutrition In-Young Choi, Ph.D., an associate professor of neurology at KU Medical Center, and Debra Sullivan, Ph.D., professor and chair of dietetics and nutrition at KU Medical Center, published a joint article on the benefits of milk in preventing degenerative brain disease in elderly people. They had 60 older people take a brain scan after quizzing them on what they recently ate and drank. They found that the people who regularly drank milk had the highest levels of glutathione in their brains. Why is this important? Glutathione is an extremely powerful anti-oxidant proven to protect the brain from metabolic rust.
Choi’s team found that people who equaled or exceed the 3 recommended servings of dairy per day had the highest levels of glutathione. Their next study is scan the brains of people who do and do not drink much milk to compare the level of cell damage from metabolic rust in their brains.
