Caseine turning on cancer--sort of. Not really. Sometimes limiting an amino acid can limit growth--both in the full organism, and in a cancer.
Campbell was involved in some work intended to alleviate protein malnutrition in poor children with peanuts as the protein source. It was discovered after this that aflavotoxins in peanuts cause liver cancer. Subsequently, he did the studies showing that low protein intake decreased the cancer promoting effects of aflavotoxin. Animals meeting their amino acid requirements from plant proteins aren't protected vs. animals meeting their amino acid requirements from caseine--since with an incomplete protein, protein requirements go up, at the same total protein intake, gluten fed animals are effectively more protein restricted than caseine fed animals.
And then there's this;
Quote:
Campbell never tells us, however, that these Indian researchers actually published this paper as part of a two-paper set, one showing that low-casein diets make aflatoxin much more acutely toxic to rats (1), and the other showing that these same diets make aflatoxin much less carcinogenic (2).
In the very paper (2) that Campbell cites as a revelation to die for, showing that a high-protein diet turns the cancer switch to the on position, the low-protein diet proved lethal to the animals. The investigators gave rats a small dose of aflatoxin every day for six months and fed them either a 5 percent casein or 20 percent casein diet. The experiment carried on for two years, in fact, but they stopped adminstering aflatoxin at six months for the simple reason that half the animals on the low-protein diet had died. They had typical symptoms of aflatoxin toxicity including liver necrosis (cell death), proliferation of bile duct tissue, and fatty liver.
All the animals receiving 20 percent casein, on the other hand, were still alive at that point. For the remainder of the two years, the rats receiving 20 percent casein continued to live longer, but many of them developed liver cancer or pre-cancerous changes, while none of the rats fed 5 percent casein developed liver cancer.

Aside from anything else, how do we know that the animals that died from more direct toxic effects of aflatoxin weren't just the ones that would have gone on to develop liver cancer, if they'd been fed a less ridiculous diet?
Nothing against vegetarian diets, you just need enough protein.
