Researchers writing in the American Journal of Clinical Nutrition say that green tea consumption can improve cognitive function. The researchers measured the effects of drinking 3 cups a week, 4 to 6 cups a week, and two cups a day.
From the study abstract:
Background: “Although considerable experimental and animal evidence shows that green tea may possess potent activities of neuroprotection, neurorescue, and amyloid precursor protein processing that may lead to cognitive enhancement, no human data are available.”
Objective: “The objective was to examine the association between green tea consumption and cognitive function in humans.”
Results: “Higher consumption of green tea was associated with a lower prevalence of cognitive impairment.”
Conclusion: “A higher consumption of green tea is associated with a lower prevalence of cognitive impairment in humans.”
