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.

One way to identify the optimal human diet, pretty obvious to all but fundamentalist reductionists, is to survey and compare populations as they already exist, and see what they eat and how healthy they are.

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

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

Nutrition trumps genes.

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.

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.
