Let’s start with the most prominent ecological crisis of our time: global warming. When you look seriously at the numbers, you find that switching from a meat-based to a plant-based diet would do more to curb and reverse global warming than any other initiative.

Americans love to hear good things about their bad habits.

Nutrition trumps genes.

Excessive animal protein is at the core of many chronic diseases.

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 short, it is about the multiple health benefits of consuming plant-based foods, and the largely unappreciated health dangers of consuming animal-based foods, including all types of meat, dairy and eggs.

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.
