Did you know that carbs are killing you? And not just unhealthy carbs like sugar and white bread but healthy carbs, too. That's right: whole grains, brown rice, even certain fruits are destroying your brain, causing: * dementia * ADHD * anxiety * insomnia * chronic headaches * depression In GRAIN BRAIN, David Perlmutter, MD, explains what happens when the brain encounters common carbs like wheat and fructose the natural sugar found in fruit and why an extremely low-carb, high-fat diet is ideal. He debunks beliefs about antioxidants, demonstrates how we can take control of the "master switches" in our DNA and offers an in-depth look at some of our most pernicious maladies, explaining how all of these can be remedied without drugs. The book offers a 30-day plan to a healthier brain - with daily menus, recipes and supplement recommendations. With anecdotes based on Dr. Perlmutter's work, scientific research and more, GRAIN BRAIN teaches us how we can take control of our brain health and change our lives forever.
