Fat is your friend. The brain thrives on a fat-rich, low-carbohydrate diet.

The best diet for overall health, and specifically for heart, brain, and cancer risk reduction, is a diet that's aggressively low in carbohydrates with an abundance of healthful fat, and this is the central theme of 'Grain Brain.'

Two forms of fat that are vitally important for brain health are cholesterol and saturated fat.

Saturated fat is a fundamental building block for brain cells. It's certainly interesting to consider that one of the richest sources of saturated fat in nature is human breast milk.

A friend doesn't go on a diet because you are fat.

Our ancestors relied upon their advanced brains to survive during times of food shortage, and fortunately, the human brain is able to utilize body fat as an extremely efficient fuel to sustain function when glucose-providing food is unavailable.
