Not exact matches
There are neurotoxins in the form
of aflatoxins in peanuts, almonds and walnuts, brazil nuts, that I feel are far worse and
more highly consumed.
But in underdeveloped countries, especially in some parts
of Africa,
aflatoxin exposure rates go up to
more than 90 percent.
In
more realistic models where the rats were dosed with smaller (but still large) amounts
of aflatoxin every day, the low - protein diets proved fatal, even in adulthood.
The results suggested that low doses
of aflatoxin were both
more toxic and
more carcinogenic to monkeys fed low - protein diets.
That's the direction I'm pushing, not perfection, but just awareness
of problems,
more research, and I've got about 900 studies on OTA and 1,200 on
aflatoxin.
The model
of aflatoxin - dosing used in these studies, discussed in
more detail below, was much
more realistic than the model used in most
of Campbell's studies, and thus the balance
of the evidence suggests that adequate protein likely offers very powerful protection against cancer in someone who hasn't already developed the disease.
Indeed, the researchers weren't pulling our legs: This study really did show that a low - protein diet was both
more «cancer promoting» and
more deadly than a high - protein diet when the dose
of aflatoxin was lower.
Monkeys on low protein diet [with 0.16 ppm
aflatoxin] surviving for 90 weeks or
more show foci
of preneoplastic lesions, whereas those on high protein diet reveal no such alterations at the corresponding time interval.
In the late 1980s,
more researchers from India were conducting experiments with casein and cancer — but this time used different doses
of aflatoxin, and studied rhesus monkeys instead
of rats.
Please read my Forks Over Knives review for
more information on what's wrong with the conclusions drawn from Campbell's casein /
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.
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).
There are neurotoxins in the form
of aflatoxins in peanuts, almonds and walnuts, brazil nuts, that I feel are far worse and
more highly consumed.
With
more realistic doses
of aflatoxin, protein is actually tremendously protective against cancer, while protein - restricted diets prove harmful.
More clues for understanding the casein - cancer research come from another Indian study — this one published in the late 1980s, and examining the effects
of protein in
aflatoxin - exposed monkeys instead
of rats.14 As with Campbell's experiments, the monkeys were fed diets containing either 5 percent or 20 percent casein, but with one important difference: instead
of being slammed with an astronomically (and unrealistically) high dose
of aflatoxin, the monkeys were exposed to lower, daily doses — mimicking a real - world situation where
aflatoxin is consumed frequently in small amounts from contaminated foods.
But I was not comfortable taking the usual path
of declaring that casein is a carcinogen that was far
more powerful than
aflatoxin («the most potent carcinogen ever discovered» according to the people who favor the chemical carcinogen hypothesis).
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
aflatoxin, ochratoxin and some
of the other common mycotoxins in our food supply at levels that are some sometimes considered safe and that by lowering those like making better choices like not eating something as simple as raisins.
For instance, it would be unethical to dose a group
of volunteers with high - cholesterol foods to see if they had
more heart attacks, or to feed them high doses
of the fungal poison
aflatoxin to determine whether they suffered
more cases
of liver cancer.
