According to several studies featured on Forbes.com, it’s possible to lower your risk of Alzheimer’s disease by drinking green tea.
One of the studies, which was published in the European Journal of Clinical Nutrition, involved 12 participants who were asked to either drink a cup of green tea or a cup of placebo. A memory-stimulating task was performed after each cup, while brain activity was scanned using MRI technology.
The results showed that after drinking green tea, brain activity increased in the dorsolateral prefrontal cortex, the part of the brain associated with processing and memory. The higher the green tea consumption, the more active the brain became. The same effect was not recorded after the placebo was taken.
Based on other studies, the presence of epigallocatechin-3-gallate (EGCG), a flavonoid in in green tea, is primarily the key to lowering the risk of cognitive decline. Researchers believe that the EGCG binds to beta-amyloid and stops it from forming amyloid plaques that cause Alzheimer’s disease.
