Three cups of milk a day can boost brain health in adults

Everyone knew that consuming milk is good for development of child’s brain, however, a new study has revealed that milk intake is good for adult’s brain too. According to the researchers, they successfully found an interlink between milk consumption and the levels of the naturally occurring antioxidant glutathione in the brain of older and healthy adults.

Milk plays a vital role in strengthening bones and muscles, but milk can be important for brain as well, found lead researcher 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.

The study at KU Medical Center’s Hoglund Brain Imaging Center involved 60 participants. Researchers observed diet of every participant and took their brain scans to monitor the levels of glutathione, a powerful antioxidant present in the brain.

After analysing the data, the study authors found that the participants who included milk in their diet showed higher amount glutathione in their brains. Researchers say that high volume of antioxidant can neutralise the oxidative stress present in the brain. Also, it can reverse the damage caused by reactive chemical compounds produced during the normal metabolic process in the brain.

Oxidative stress is the root of several disease including Alzheimer, Parkinson and several other diseases, said Choi. He added that the body automatically generates antioxidants to fight against oxidative stress, however, in some cases people need external driving force to produce the extra antioxidative substance, and milk can become that driving element. One should also notice the fact that stress has become one of the most common disease around the globe, gripping millions of people.

Furthermore, Choi recommended every adult to consume three servings of milk per day for better memory later in life. It was found that the closer an adult was to three cup mark, healthier the brain was. “If we can find a way to fight this by instituting lifestyle changes including diet and exercise, it could have major implications for brain health,” Choi says.

The study appeared in the journal Clinical Nutrition.
