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

The answer to the American health crisis is the food that each of us chooses to put in our mouths each day. It's as simple as that.

If you flip a coin three times and it lands on heads each time, it’s probably chance. If you flip it a hundred times and it lands on heads each time, you can be pretty sure the coin has heads on both sides. That’s the concept behind statistical significance—it’s the odds that the correlation (or other finding) is real, that it isn’t just random chance.

I know of nothing else in medicine that can come close to what a plant-based diet can do. In theory, if everyone were to adopt this, I really believe we can cut health care costs by seventy to eighty percent. That's amazing. And it all comes from understanding nutrition, applying nutrition, and just watching the results.

No chemical carcinogen is nearly so important in causing human cancer as animal protein.

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

You can't be protein deficient without being calorie deficient because even if you take the foods that have the least amount of protein in them, let's say potatoes, for example, or rice at 8 or 9%. That's the figure we more or less need.
