Grain Brain
Dr. David Perlmutter’s *Grain Brain* shatters long-standing myths about brain health, exposing how modern grains, gluten, and refined carbs silently erode cognitive function. Framing Alzheimer’s as “Type 3 Diabetes,” he explains that brain insulin resistance—sparked by excess carbs—blocks glucose uptake, fuels chronic inflammation, and builds toxic beta-amyloid proteins, leading to memory loss, dementia, and mood disorders like depression or ADHD. He debunks the “cholesterol is harmful” myth, showing cholesterol is critical for brain cell integrity, and breaks down how modern grains’ 40x higher gluten content causes gut damage and addictive responses. Packed with actionable strategies, the book outlines a low-carb, high-fat, gluten-free diet, plus science-backed tips on exercise, sleep, and intermittent fasting to boost BDNF (the brain’s “growth hormone”) and trigger neurogenesis. With a 4-week step-by-step plan and easy recipes, it gives readers the tools to reverse cognitive decline and protect long-term brain health.
