Green Tea is Neuroprotective
We have seen before on these pages and elsewhere how Green Tea has been implicated in protecting against brain ischemia. Ischemic stroke occurs when an artery to the brain is blocked. The brain depends on its arteries to bring fresh blood from the heart and lungs. The blood carries oxygen and nutrients to the brain, and takes away carbon dioxide and cellular waste. If an artery is blocked, the brain cells (neurons) cannot make enough energy and will eventually stop working. If the artery remains blocked for more than a few minutes, the brain cells may die.
Green Tea is a rich source of polyphenols, particularly (-)-epigallocatechin gallate (EGCG) and the results presented by Silva et al demonstrated the beneficial effects of Green Tea in diabetic retinas and in retinal cells under diabetic conditions.
Diabetes was induced in spontaneously in an animal model. Various positive changes were observed after Green Tea treatments in the diabetic model. In conclusion, treatment with Green Tea fully restored negative alterations in diabetic animals as well as in retinal cells.
The researchers suggest that Green Tea protected the retina against glutamate toxicity via an anti-oxidant mechanism. The results indicate a novel mechanism by which Green Tea could protect the retina against neurodegeneration in disorders such as diabetic retinopathy.
