I have found the various assaults on the WHO Report to be predominantly silly - and served with more than a soupscon of self-interestedness. I found a very useful article on the rather apolitical The Conversation website. The author is a well-respected Australian physician/scientist and “Chair of the IARC Working Group set up to evaluate the carcinogenicity of red and processed meat.” The purpose of the piece was primarily to provide context and is a worthwhile read. http://theconversation.com/not-everything-gives-you-cancer-but-eating-too-much-processed-meat-certainly-can-49812
If nothing else, the following excerpt is valuable:
"The equivalence between smoking and eating processed meat exists when it comes to strength of evidence for cancer causation. But otherwise indicating similarity is a distortion, particularly because of the respective burdens of cancer.
Lifetime smoking increases risk of lung cancer 50-fold. But worst case scenarios in relation to processed meat or red meat rarely reach more than two-fold. The 18% increased risk means risk is multiplied by 1.18.
Moreover, meat is a food as distinct from a poison such as asbestos, and so these findings must be understood with the subtlety of reason."
