Green tea supplementation produces better neuroprotective effects than red and black tea in Alzheimer-like rat model.
Wistar male rats were supplemented with green, red or black tea during 8weeks before Aβ intra-hippocampal injection (2μL of Aβ-25-35, CA1 region). AD and sham rats were submitted to memory tests. After euthanasia, oxidative status in the bilateral hippocampus was quantified. Green and red teas avoid memory deficits in AD rats, but only green tea also avoids oxidative stress and damage in the hippocampus. Green tea was more effective for neuroprotection than red and black teas from the Camellia sinensis in the AD rat model.
