Green Tea and Alzheimer's
Green Tea Inhibits Enzymes Associated with Alzheimer's
A study, published in the journal Phytotherapy Research, shows that green tea inhibits certain enzymes linked with the development of Alzheimer's Disease.
Both green tea and black tea inhibited two enzymes which play different roles in Alzheimer's, but green tea further inhibited a third enzyme which is associated with the production of protein deposits that occur in the brain. These protein deposits are a hallmark of Alzheimer's Disease.

In addition, the researchers discovered that green tea's inhibitory effects lasted for a week, but black tea's effects lasted just a day. The study also found that coffee had no effect. The lead researcher in the study said that regular consumption of green tea could help preserve memory function and prevent memory loss.
Green Tea Extract for Alzheimer's
Another study, published in the Journal of Neuroscience, suggests that drinking green tea may not be enough. This research indicates that some of green tea's other antioxidants may counteract the effects of EGCG, green tea's main Alheimer's fighing antioxidant. The researchers suggest that a green tea extract with concentrated EGCG might be necessary to overcome the counteractive effects of the other antioxidants in green tea.
