How Eating Affects Our Brain

From Psychology Today:
I recently stumbled onto a book that opened my eyes in many ways to the misinformation plaguing Americans regarding healthy eating, particularly where it concerns brain health. The book, Grain Brain, by Dr. David Perlmutter, is mind-blowing—no pun intended—and disruptive to some long-standing beliefs about what our bodies require for optimal health.

"The brain thrives on a fat-rich, low-carbohydrate diet, which unfortunately is relatively uncommon in human populations today," he says. Carbohydrates typically thought of as healthy, even brown rice, 100% whole grain bread, or quinoa—mainstays of many of the most health-conscious kitchens—cause disorders like dementia, ADHD, chronic headaches, and Alzheimer’s, over a lifetime of consumption. By removing these carbohydrates from the diet—harbingers of inflammation, the true source of problems that plague our brains and hearts—and increasing the amount of fat and cholesterol we consume, we can not only protect our most valuable organ, but also potentially, undo years of damage. Cholesterol, for example, long vilified by the media and medical community, actually promotes neurogenesis (the birth of new brain cells) and communication between neurons, to the degree that studies have shown that higher levels of serum cholesterol correlates to more robust cognitive prowess.
