Animal Protein as a Carcinogen

Reply to a Reader’s Query:

Though there are numerous arguments favoring the dietary imbalance clarification of most cancers, one of many extra placing for me was the experimental animal research mentioned in Chapter 3 in my guide, The China Study. Specifically, aflatoxin is a really potent carcinogen for the rat. Nevertheless, after the Indian researchers confirmed that lowering protein (casein) consumption from the standard degree of consumption of 20% to five% utterly prevented this very highly effective carcinogen to trigger most cancers, we then started our work (references in our guide). We explored that discovering in nice depth and finally confirmed their preliminary remark. That’s, easy adjustment of dietary protein (casein) inside very regular ranges of protein consumption managed most cancers development and it labored not by one mechanism however by a big array of mechanisms. In different phrases, we proved this affiliation past any doubt.

Additional, through the years, this analysis required loads of funding and our purposes for funding have been reviewed by different researchers extremely skilled on this area. Each time we obtained excessive marks for the standard of the analysis. Then, after we submitted the outcomes for publication, they have been once more reviewed by friends and these papers have been revealed in the perfect most cancers analysis journals. Among the many individuals who know probably the most about most cancers, our work was totally convincing.

Very merely, regular adjustment of protein consumption was able to enormously influencing the power of a chemical carcinogen’s capability to advertise most cancers. Dietary protein trumped a really highly effective carcinogen in a species that was exceptionally delicate to this carcinogen.

Then we did a lot the identical factor with a most cancers attributable to a virus, the hepatitis B virus.

If we observe the standards of figuring out what’s a carcinogen and what’s not, these findings ought to shake up all the world of most cancers analysis and schooling as a result of that is the way in which that different carcinogens (Alar, dioxin, DDT, and so on.) additionally work–besides the proof favoring their carcinogenicity is way lower than it’s for aflatoxin!

However I used to be not comfy taking the standard path of declaring that casein is a carcinogen that was way more highly effective than aflatoxin (“probably the most potent carcinogen ever found” based on the individuals who favor the chemical carcinogen speculation). As a substitute, I used to be extra fascinated about asking broader questions, involving the position of animal protein primarily based meals of their affiliation with human most cancers, in addition to to check the comparative associations of aflatoxin consumption and protein consumption in people–this was the China Research.

I’ve given this story to most of the absolute best–and most important audiences — that I can discover (Harvard, Berkeley, Cornell, Emory, Yale, Duke, NIH, and so on.) and I get no severe criticism. The one remark that appears to floor quite a lot of occasions is ‘I’m taking over some very highly effective pursuits they usually gained’t hear — whatever the veracity of the proof’, or phrases to that impact. In different phrases, this difficulty — first narrowly outlined however later expanded right into a a lot bigger difficulty — is usually about politics, economics, private bias, and so on., and never about rational science. Fairly actually, it depresses me as a result of there may be a lot at stake for human well being. Company America, who controls the agenda on this well being analysis enterprise, is extra fascinated about their very own well being than they’re within the well being of the general public!
