Q: I have read that fasting (or eating very lightly) a couple of days per week can do wonders for one's health, and for the brain in particular. Is this true?

A: There is some research out of the United States that intermittent fasting may be beneficial to brain functions. In particular, this may apply to Parkinson's disease and Alzheimer's. However, since the improvement in brain functions has been studied only in rats, one must be careful as it may not extrapolate to the same effect in humans. I believe more research is needed.
