The author is a practicing neurologist in Florida in his 60s.
Renowned neurologist David Perlmutter, MD, blows the lid off a topic that's been buried in medical literature for far too long: carbs are destroying your brain. And not just unhealthy carbs, but even healthy ones like whole grains can cause dementia, ADHD, anxiety, chronic headaches, depression, and much more. Dr. Perlmutter explains what happens when the brain encounters common ingredients in your daily bread and fruit bowls, why your brain thrives on fat and cholesterol, and how you can spur the growth of new brain cells at any age. He offers an in-depth look at how we can take control of our "smart genes" through specific dietary choices and lifestyle habits, demonstrating how to remedy our most feared maladies without drugs. With a revolutionary 30-day plan, GRAIN BRAIN teaches us how we can reprogram our genetic destiny for the better.
It's an intriguing read and its core idea is gaining increasing support from other MDs. Bottom line: grain was introduced into humans' diets with the birth of agriculture and civilization circa 10,000 years ago. Prior to that, we hunter-gatherers existed primarily on meats, leafy vegetables, roots, nuts, seeds, and berries. Those are the things we evolved to eat, digest, and metabolize. Carbohydrates are not necessary for humans to thrive, and may be doing us far more harm than good, especially when it comes to neurological health. The brain craves dietary fat, and we cannot live without it. Stop demonizing fat and embrace it and protein sources as your primary sources of calories. Carbs not just bad, but much worse than we've ever thought, and for different reasons.
Not advocating for it, just relaying his message, but I'm trying out his dietary suggestions.
