Grain Brain: The Surprising Truth about Wheat, Carbs, and Sugar--Your Brain's Silent Killers

Dr. David Perlmutter argues that gluten, processed carbohydrates, and excess sugar trigger chronic inflammation that directly degrades neurological health. The text identifies these dietary components as primary contributors to conditions including dementia, ADHD, anxiety, and chronic headaches. Perlmutter explains the physiological mechanism of glucose spikes and internal glycation, asserting that even "healthy" whole grains can cause brain dysfunction. He advocates for a high-fat, low-carbohydrate ketogenic diet to protect neurons and suggests specific supplements to support mitochondrial function and neurogenesis.

This book serves individuals seeking to prevent cognitive decline or manage existing neurological symptoms through lifestyle changes. Readers often approach this material to understand the link between gut health and mental clarity.
