A new study released by the University of Kansas Medical Center has determined that there is a correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione.
The research study consisted of 60 participants in the study who were asked about their diet and who had their brain imaged in order to measure the level of glutathione. “We have long thought of milk as being very important for your bones and very important for your muscles,” said Debra Sullivan; Ph.D., professor and chair of dietetics and nutrition. “This study suggests that it could be important for your brain as well.”
The findings reflected that participants who had consumed milk recently had higher levels of glutathione in their brains. The researchers believe that 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.
“You can basically think of this damage like the buildup of rust on your car,” Sullivan said. “If left alone for a long time, the buildup increases and it can cause damaging effects.
The researchers recommend that Americans reach the recommended daily intake of three dairy servings per day, as the findings revealed that the closer the older adults came to those servings, the higher their levels of glutathione were.
