„We're basically a vegetarian species and should be eating a wide variety of plant foods and minimizing our intake of animal foods. … 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're realizing that animal-based agriculture is not the way to go. … Ironically, osteoporosis tends to occur in countries where calcium intake is highest and most of it comes from protein-rich dairy products. The Chinese data indicate that people need less calcium than we think and can get adequate amounts from vegetables.“
— T. Colin Campbell American biochemist 1934
