Award-winning neurologist and scholar Dr. David Perlmutter makes a compelling case for a grain-free lifestyle in his nonfiction book, Grain Brain. He claims that carbohydrates hinder brain development, impairing cognitive function and contributing to the development of neurological diseases, such as Alzheimer's and dementia. Most diseases of the brain, he argues, are preventable when one eats properly and adopts other healthy habits. He then gives readers the insight and advice they need to improve their lives and keep their brains functioning at peak efficiency for decades to come.
This summary explores the major ideas found in Grain Brain, as well as the key take-aways from each chapter. Use it to help you make sense of the key thoughts Perlmutter presents and understand why the foods you eat play such an important role in your brain's health. The book also presents readers with lists of must-have dietary staples, foods to consume in moderation, and foods to avoid, along with recipes that are both nutritious and tasty.
Still, listeners may want to approach Grain Brain with caution: Although he uses scientific studies to back up his claims, Perlmutter does not acknowledge or respond to work that directly contradicts his own sources, which hampers his credibility. He also makes some illogical claims with no research to back them up. Allow our summary of Grain Brain to give you a complete picture of everything you should take away from this nonfiction piece.
