Guest guest Posted July 15, 2002 Report Share Posted July 15, 2002 Japan has a much lower rate of Alzheimer's disease than Western countries. The Japanese living in Hawaii have 2.5 times the incidence of Alzheimer's disease than do native Japanese in Japan. It would be interesting to see to what extent the Japanese custom of sipping green tea all day, as contrasted with much lower consumption of green tea by the American-Japanese, contributes to neural protection. (this is why there may be a corrolation with autism as well??) There is also some evidence that iron plays a part in epilepsy. Green tea polyphenols have been found to inhibit or diminish iron-induced epileptic seizures, and to inhibit the hyperactivity of dopaminergic neurons. It is in fact likely that green tea, especially the decaffeinated kind, acts as a mild sedative. Theanine, an amino acid found in green tea, has also been found to have beneficial effects by raising the levels of serotonin and/or dopamine in various important brain regions, particularly the hypothalamus, hippocampus (memory center), and striatum.
