Quoted from The Hundred-Year Lie:

A macrobiotic food regimen, based on principles that are thousands of years old, emphasizes vegetables, fresh fruits, and whole grains but severely restricts meat, dairy products, and processed foods of any sort. The theory behind the diet is to limit the absorption of toxins while flooding the body with essential nutrients, and combining that with exercise and periods of rest and meditative solitude. It is all about creating a balanced condition in life and a natural healing synergy.
