Could a High-Carb Diet Increase Risk of Dementia?

Could a High-Carb Diet Increase Risk of Dementia?A new theory suggests that even small increases in blood sugar caused by a diet high in carbohydrates can be detrimental to brain health.

Some studies link carbohydrate calorie-rich diets to a greater risk for brain shrinkage, dementia and Alzheimer’s disease, impaired cognition, and other disorders.

David Perlmutter, M.D., best-selling author of Grain Brain, explores this important topic in a provocative interview in the journal Alternative and Complementary Therapies from Mary Ann Liebert, Inc., publishers.

In the interview “Rethinking Dietary Approaches for Brain Health,” Perlmutter says, “We live with this notion that a calorie is a calorie, but at least in terms of brain health, and I believe for the rest of the body as well, there are very big differences between our sources of calories in terms of the impact on our health.

“Carbohydrate calories, which elevate blood glucose, are dramatically more detrimental to human physiology, and specifically to human health, than are calories derived from healthful sources of fat.”

Perlmutter presented his theory on how brain health and cognitive function are linked to nutrition in his presentation, “The Care and Feeding of Your Brain,” during the 2014 Integrative Healthcare Symposium.
