Perhaps it is a testament to the power of modern marketing savvy that an obese man with heart disease and high blood pressure became one of the richest snake oil salesmen ever to live, selling a diet that promises to help you lose weight, to keep your heart healthy and to normalize your blood pressure.

First, nutrition is the master key to human health. Second, what most of us think of as proper nutrition--isn't.

Nutrition trumps genes.

The ideal human diet looks like this: Consume plant-based foods in forms as close to their natural state as possible (“whole” foods). Eat a variety of vegetables, fruits, raw nuts and seeds, beans and legumes, and whole grains. Avoid heavily processed foods and animal products. Stay away from added salt, oil, and sugar. Aim to get 80 percent of your calories from carbohydrates, 10 percent from fat, and 10 percent from protein.

Everything in food works together to create health or disease. The more we think that a single chemical characterizes a whole food, the more we stray into idiocy.

In the next ten years, one of the things you're bound to hear is that animal protein is one of the most toxic nutrients of all that can be considered. Quite simply, the more you substitute plant foods for animal foods, the healthier you are likely to be.

A good diet is the most powerful weapon we have against disease and sickness.
