Grain Brain is the catchy title of a new self-help diet book on the New York Times Advice and How-to Best Sellers lists. The author, neurologist David Perlmutter, makes the case for a slow death to brain cells caused by wheat, “carbs,” and sugar. Those foods, he says, are behind most of the common but incurable neurologic diseases including Alzheimer’s, dementia, autism, anxiety, depression, and others. To prevent and treat those conditions, he recommends a diet of fish, seeds, nuts, and olive oil, sans the “carbs” from grains, milk, fruit, and sugary sweets. Grain Brain is in the same vein as Wheat Belly and other best-selling Paleo-type diet books.
David Perlmutter and his co-author, writer Kristin Loberg, followed the diet book formula: reel in the lay audience with indisputable scientific facts and then lead them to ungrounded conclusions because they all sound good. With technical expertise, Dr. Perlmutter explains the workings of the brain and central nervous system. He is up on the hot nutrition topics and buzzwords of the day: inflammation, free radicals, bacteria in the gut, and metabolic fuels.
