DURING THE PAST TWO TO THREE DECADES, we have acquired substantial evidence that most chronic diseases in America can be partially attributed to bad nutrition. Expert government panels have said it, the surgeon general has said it and academic scientists have said it. More people die because of the way they eat than by tobacco use, accidents or any other lifestyle or environmental factor.

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

Cows' milk protein may be the single most significant chemical carcinogen to which humans are exposed.

Usually, the first thing a country does in the course of economic development is to introduce a lot of livestock. Our data are showing that this is not a very smart move and the Chinese are listening. They are realizing that animal-based agriculture is not the way to go.... We are basically a vegetarian species and should be eating a wide variety of plant food and minimizing our intake of animal foods.

A plant-based diet is more likely to produce good health and to reduce sharply the risk of heart problems, cancer, diabetes, osteoporosis, gallstones, and kidney disease.

We now had impressive evidence that low protein intake could markedly decrease enzyme activity and prevent dangerous carcinogen binding to DNA.

In every respect, vegans appear to enjoy equal or better health in comparison to both vegetarians and non-vegetarians.
