Dr. Oz is a vegetarian who encourages eating whole-grain wheat and lots of fruit, but neurologist David Perlmutter says a high-carb, grain-heavy diet destroys the brain and fuels Alzheimer's disease.
Drs. Oz and Perlmutter discussed the health benefits of a low-carb, high-fat, grain-free diet and its impact on brain health on the Oct. 21 episode of the Dr. Oz Show.
After speaking with Perlmutter, Dr. Oz agreed that consuming healthy fats and limiting carbs can help prevent and even reverse conditions such as Alzheimer's disease, diabetes, and ADHD.
Perlmutter is not alone in his assessment that a low-carb, high-fat diet can curb disease. Cardiogist William Davis said it can reverse diabetes. Another cardiologist, Dr. Aseem Malhotra confirmed that unprocessed saturated fat is healthy and can protect against heart disease.
And obesity expert Dr. Eric Westman said a low-carb, high-fat ketogenic diet produces rapid weight loss without exercise or calorie-counting.
In a surprise revelation, endurance athletes observed that a ketogenic diet can enhance athletic performance. And cancer researcher Dr. Dominic D'Agostino confirmed that a ketogenic diet starves cancer cells.
Dr. Perlmutter, a neurologist, explained that a grain-heavy, high-carb diet causes neurological breakdown because the brain is hyper-sensitive to the foods we eat.
Perlmutter says we can ward off — and in most instances reverse — Alzheimer's disease, dementia, diabetes and ADHD by following a low-carb, gluten-free, high-fat diet (such as the ketogenic, Paleo, or Atkins diet) that drastically limits carbs, including most fruit.
According to Perlmutter, a high-carb diet causes inflammation, which has a catastrophic effect on brain cells, as well as the entire body.
Carbs are devastating for the brain. The brain thrives on a fat-rich, low-carbohydrate diet. Fat is your friend."
Perlmutter's stance is diametrically opposed to Dr. Oz's longstanding low-fat diet dogma. But Dr. Oz is now convinced that consuming lots of healthy fats (such as olive oil, avocado, nuts and salmon) and limiting carbs (especially processed carbs) is an effective way to prevent and repair neurological damage.
Dr. Perlmutter recommends a low-carb diet — limiting carbs to no more than 80 grams a day — and eating lots of dietary fats, such as extra-virgin olive oil, avocado, grass-fed butter, wild fish, grass-fed beef, coconut oil, nuts. "The fate of your brain is not in your genes; it's in the food you eat," he said.
