Cutting carbs isn't a cure-all for brain disease

New, 33 comments

Dr. David Perlmutter, author of the bestselling book, Grain Brain: The Surprising Truth about Wheat, Carbs, and Sugar — Your Brain's Silent Killers, says everything you know about food is wrong. According to Perlmutter, the carbohydrates you eat every day are destroying your brain, gluten is as damaging as drinking gasoline, and as a species we should bring our diets back to a paleolithic "hunter-gatherer" ideal to avoid disease and obesity. Dr. James Hamblin is unconvinced. In a report for The Atlantic, Hamblin questions the carb-averse doctor's selective sourcing in support of his "ardently and unwaveringly delivered" argument, suggesting Perlmutter's simple way to avoid lethal and degenerative diseases we do not yet understand is little more than one-sided pop-science.
