I just downloaded Grain Brain on iBooks today. It’s a potentially game changing book by a prominent board-certified neurologist, David Perlmutter, who also happens to be a Fellow of the American College of Nutrition.

The basic point of the book: carbohydrates are toxic for your brain. Seriously. Even so-called healthy whole grains and most fruit.

He’s even got traditionally conventional low-fat/whole grain-touting Dr. Oz turning around on this. Here’s Perlmutter on Oz’s show discussing how carbohydrate consumption may be a key culprit in the rise of Alzheimer’s.

Conventional wisdom has been stubborn, but I’m seeing more mainstream acceptance recently of the merits of a low-carb/high-fat diet. Usually, it’s related to fighting obesity and diabetes. This focus on brain health, though, is startling and may make for a double-whammy that begins to change our culture’s attachment to the old, failed emphasis on cutting fat and eating more whole grains.

I know just reading the first few pages of this book has me recommitting to a low-carb approach. Both my brain and my waistline will thank me.
