Low Carb Paleo and Ketogenic Diets Prevent Alzheimer’s, ADHD

A neurologist says low-carb diets can prevent ALzheimer's.

Low-carb diets can prevent Alzheimer’s, says neurologist.

The low-carb ketogenic and Paleo diets can prevent Alzheimer’s disease and reverse ADHD, says neurologist Dr. David Perlmutter.

Dr. Perlmutter told Examiner we can prevent most degenerative diseases, including dementia, diabetes, obesity, heart disease and cancer by following the low-carb, gluten-free ketogenic and Paleo diets. Perlmutter detailed his research in his book, Grain Brain.

The ketogenic diet is a low-carb, high-fat, moderate-protein diet that has been shown to promote rapid weight loss, treat epilepsy, and reverse type 2 diabetes. Researcher Dr. Dominic D’Agostino also said the ketogenic diet starves cancer.

Obesity expert Dr. Eric Westman, co-author of Keto Clarity, agrees that carbohydrate restriction is the silver bullet for managing metabolic syndrome.

According to Dr. Perlmutter, a grain-heavy, high-carb diet causes neurological breakdown and leads to weight gain, diabetes and almost every degenerative disease known to man. “Food is medicine,” he said. “We can actually change our gene expressions with the foods we eat.”

‘Carbs Are Devastating for the Brain’

Perlmutter says we can ward off — and in some instances reverse — Alzheimer’s, heart disease, diabetes, and ADHD by following a gluten-free, low-carb, high-fat diet like the Paleo or ketogenic diet. The beauty of this is that our brain (and body) health is entirely in our hands.

Dementia should not be something we accept as a natural consequence of getting older. According to Perlmutter, a high-carb diet fuels blood-sugar surges, which cause inflammation, which in turn has a catastrophic impact on brain cells and the entire body.

“Carbs are devastating for the brain,” said Perlmutter, who also wrote The Grain Brain Cookbook. “Even slight elevations in blood sugar have been shown to increase the risk of Alzheimer’s disease,” said Dr. Perlmutter, citing an August 2013 report in the New England Journal of Medicine.

‘Fat Is Your Friend’

Dr. Perlmutter said high-quality saturated fats (such as wild salmon, extra-virgin olive oil and avocados) have neuroprotective properties that have been shown in numerous studies to prevent dementia and other brain diseases.

“Fat is your friend,” said Dr. Perlmutter. “The brain thrives on a fat-rich, low-carbohydrate diet.”

In Grain Brain, Dr. Perlmutter posits that the alarming onset of Alzheimer’s and dementia is due directly to consuming too many carbs.

Neurologist David Perlmutter says a low-carb, high-fat, grain-free diet can prevent Alzheimer’s disease.

Sadly, the U.S. government has long advocated a high-carb, low-fat diet, suggesting that Americans eat three to six servings of grains a day — a recommendation Perlmutter says is unhealthy and motivated more by corporate greed than public-health considerations.

Dr. Perlmutter says the brain — and the body — needs plenty of essential fatty acids to function properly. People who want to be healthy physically and mentally should consume a high-fat, low-carb diet and eschew the low-fat, high-carb, grain-centric diet espoused by the Standard American Diet (SAD).

Dr. Perlmutter suggests limiting carb intake to no more than 80 grams a day. His dietary guidelines include the following:

  • Avoid or drastically reduce gluten, grains and sugar.
  • Limit fruit consumption.
  • Avoid sugary sodas, processed foods and junk foods.
  • Eat organic vegetables.
  • Consume organic animal proteins that are free of hormones and antibiotics.
  • Get enough omega-3 fatty acids.
  • Eat good fats such as avocados, olive oil, coconut oil, nuts, fatty fish and grass-fed beef.

While we have come to accept physical and mental deterioration as the norm as we age, Dr. Perlmutter says we can prevent such breakdowns simply by controlling what we put into our mouths.

“The fate of your brain is not in your genes; it’s in the food you eat,” he said.
