About this product

Discover the devastating truth about the effects of wheat, sugar, and carbs on the brain, with a 4-week plan to achieve optimum health. In Grain Brain, renowned neurologist David Perlmutter, MD, exposes a finding that's been buried in the medical literature for far too long: carbs are destroying your brain. Even so-called healthy carbs like whole grains can cause dementia, ADHD, epilepsy, 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. The cornerstone of all degenerative conditions, including brain disorders, is inflammation, which can be triggered by carbs, especially containing gluten or high in sugar. Dr. Perlmutter explains what happens when the brain encounters common ingredients in your daily bread and fruit bowls, how statin drugs 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. Dr. Perlmutter's revolutionary 4-week plan shows you how to keep your brain healthy, vibrant, and sharp while dramatically reducing your risk for debilitating neurological diseases as well as relieving more common, everyday conditions—without drugs. Easy-to-follow strategies, delicious recipes, and weekly goals help you to put the plan into action. With a blend of anecdotes, cutting-edge research, and accessible, practical advice, Grain Brain teaches you how to take control of your "smart genes," regain wellness, and enjoy lifelong health and vitality.

Editor's Take

Grain Brain draws mixed reactions from readers and reviewers. Amazon reviewers generally praise it for being eye-opening and motivating, especially for people interested in low-carb or gluten-free diets, while some readers say it repeats ideas too much or feels overly absolute. Red Pen Reviews is much more critical, arguing that many of the book’s central claims are poorly supported by evidence. Across reviews, the most common positive theme is that the book is easy to read and provocative; the most common negative theme is that it can overstate the science.

On YouTube, the search results surfaced multiple real videos about the book, including author-focused interviews and audiobook previews. The clearest matches include a video titled Dr. Perlmutter on why he wrote Grain Brain and another titled Announcing the Revised Edition of Grain Brain!, both directly tied to the book. Other results include audiobook preview content and discussion videos featuring David Perlmutter talking about the book’s main claims.

  • Amazon reviewers say the book is engaging, persuasive, and useful for readers exploring diet and brain health.
  • Some Amazon readers and outside reviewers criticize it for overstating conclusions and relying on controversial claims.
