In the 20 % casein diet they added
aflatoxin at five parts per million (5 ppm) aflatoxin, but the 5 % casein diet with only half that — 2.5 ppm.
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.
Although the U.S. and Europe have strong regulations in place to restrict how much of the toxin can be present in food, the problem has been persistent in developing countries where there are rarely tests for
aflatoxin at the market (although there are rigorous tests for crops being exported internationally).
The easiest way to achieve this is simply by feeding your cat a species - appropriate raw meat diet,
no aflatoxins at all!

aflatoxin research, and if you'd rather look
at peer - reviewed research than the words of some random internet blogger, see my collection of scientific papers based on the China Study data that contradict the claims in Campbell's book.
When rats were all fed 20 % casein, the dose that provided the maximal cancer - promoting effect, those dosed with 0.4 milligrams per kilogram body weight (0.4 mg / kg) or 1.0 mg / kg of

at all.

aflatoxin, a carcinogenic mold toxin with which peanuts are often contaminated.
In several of his experiments, when the
aflatoxin - exposed rats were fed wheat protein or soy protein in place of casein, they didn't develop any cancer — even
at the 20 percent level that proved so detrimental with casein.5 It seemed that those plant proteins were not only PETA - approved, but also the least likely to turn rat livers into tumor factories.
And one of the things that has come out from my work is that we're doing more harm to ourselves than we recognize by consuming

This connection to Diamond Pet Foods is concerning to many pet owners because Diamond Pet Foods, which manufacturers food for many other companies as well (Canidae, Kirkland, Taste of the Wild, Costco, Chicken Soup for the Pet Lover's Soul, 4Health, Dick Van Patten's Natural Balance Pet Foods, NutraGold, and others) has a long history of recalls due to Salmonella,
