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

Furthermore, a pattern was beginning to emerge: nutrients from animal-based foods increased tumor development while nutrients from plant-based foods decreased tumor development.

The people who eat the most animal protein have the most heart disease, cancer and diabetes.

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.

I was raised on a dairy farm and ate plenty of meat and eggs until about twenty years ago. I started doing nutritional research, and a decade pr so after that my family made some major dietary changes. I'm just paying attention to what the data are telling me: The scientific evidence came first.

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

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.
