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.

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.

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

Casein [the main protein found in dairy], in fact, is the most 'relevant' chemical carcinogen ever identified; its cancer-producin g effects occur in animals at consumption levels close to normal-striking ly unlike cancer-causing environmental chemicals that are fed to lab animals at a few hundred or even a few thousand times their normal levels of consumption.

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.

When absurdities get repeated often enough, they start sounding like truth.

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