THEANINE IN TEA MAY PROTECT BRAIN CELLS

   Increased oxidative stress levels in the brain have been associated with a variety of brain diseases such as Parkinson's disease, Alzheimer's disease and even brain cancer. Previous studies have suggested that green tea polyphenol EGCG may lower oxidative stress levels in the brain. It turns out that theanine (L-theanine) found in both black and green tea may also help lower oxidative stress in critical parts of the brain.
   Rats given theanine were found to have a 20% lower oxidative stress level in the brain than those not given theanine. According to the study, theanine reduced oxidative stress in a critical part of the brain for thinking and memory, the cerebral cortex.
   This study in conjunction with previous studies opens the possibility that tea contains, not one but two compounds that reduce oxidative stress: polyphenols and theanine. Whether or not this study applies to humans is unknown but suggestive. drpaulsupdates.org
