From #1 New York Times bestselling author Dr. Perlmutter, the devastating truth about the effects of wheat, sugar, and carbs on the brain, and a 4-week plan to achieve optimum health.

In Grain Brain, renowned neurologist David Perlmutter, MD, blows the lid off a finding that's been buried in medical literature for far too long: carbs are destroying your brain. Even so-called healthy carbs like whole grains can cause dementia, ADHD, anxiety, chronic headaches, depression, decreased libido, and much more.

Groundbreaking and timely, Grain Brain shows that the fate of your brain is not in your genes, it's in the food you eat. Dr. Perlmutter explains what happens when your brain encounters common ingredients in fruit bowls and bread, how statins may be erasing your memory, why a diet high in "good fats" is ideal, and how to spur the growth of new brain cells at any age. And his revolutionary 4-week plan will show you how to keep your brain healthy and sharp while dramatically reducing your risk for debilitating neurological disease -- without drugs.

Featuring a blend of cutting-edge research, real-life stories of transformation, and accessible, practical advice, Grain Brain teaches you how to take control of your "smart genes," regain wellness, and enjoy lifelong health and vitality.

"Dr. Perlmutter outlines an innovative approach to our most fragile organ, the brain.

"Dr. Perlmutter takes us on a detailed tour of the destructive effects that 'healthy whole grains' have on our brains. Modern wheat, in particular, is responsible for destroying more brains in this country than all the strokes, car accidents, and head trauma combined. Dr. Perlmutter makes a persuasive case for this wheat-free approach to preserve brain health and functioning, or to begin the process of reversal." --William Davis, MD, author of Wheat Belly
