Two food/health interactions

[deirdre]

Epidemiological research has demonstrated a positive correlation between tofu consumption and brain atrophy in men. Note: it is difficult to show positive correlations across an epidemiological study as generally an epidemiological study is against a large unfocused population. Thus, I'd tend to consider this huge, much like the epidemiological studies about smokers led to more targeted studies about the effects of smoking. Here's a link with more info about epidemiological studies and their issues; it's fairly short.

[Researchers] show that women who drink at least four cups of coffee a day are less than half as likely to develop diabetes as non-coffee drinkers.

I've excerpted out the money shot line in each case; the links give more context.
