Grain Brain

by David Perlmutter


The mistake most diet books make is assuming they can deliver a diet that works for everyone and making conclusions about what must be good solely based on what's bad.

In his book Grain Brain, neurologist David Perlmutter, M.D., examines the devastating impact carbohydrates can have on the brain. Perlmutter makes the case that your brain health lies in your diet, not your genes, and there are some simple ways to take back control.

The simple act of moving your body will do more for your brain than any riddle, math equation, mystery book, or even thinking itself.
