An ongoing area of interest for me is neuroscience. Some time ago I read that some neuroscientists drink coffee simply for health benefits – to ward off dementia. The scientific evidence is stacking up, and now a recent study shows that coffee may actually reverse Alzheimer’s. Black tea also has been shown to have significant cognitive health benefits. Oddly, in the black tea studies I have read, “coffee has not been shown to have the same benefits.” Likewise, in the coffee studies, black tea is not as effective.
