The original IARC Report was published in  The Lancet on October 26, as volume 114 of the IARC Monographs. Among the stated research findings, developed under the auspices of WHO:

  • Positive associations in cohort studies and population-based case-control studies were found between consumption of red meat and cancers of the pancreas and the prostate (mainly advanced prostate cancer), and between consumption of processed meat and cancer of the stomach. Data were also available for more than 15 other types of cancer.
     
  • A majority of the Working Group concluded that there is sufficient evidence in human beings for the carcinogenicity of the consumption of processed meat.
     
  • The Working Group concluded that there is limited evidence in human beings for the carcinogenicity of the consumption of red meat.

The World Health Organization has now issued a clarification to the report stating:

"IARC's review confirms the recommendation in WHO's 2002 'Diet, nutrition and the prevention of chronic diseases' report, which advised people to moderate consumption of preserved meat to reduce the risk of cancer."

The clarification further elaborates that …  

"The latest IARC review does not ask people to stop eating processed meats but indicates that reducing consumption of these products can reduce the risk of colorectal cancer."

To help stakeholder and public understanding on these developments, the International Food Information Council Foundation published a Newsletter Article with input from experts Dr. Roger Clemens and Dr. Julie Jones, putting the report in context: WHO Chimes in on Meats: What it Means for Your Health 

Also available from the IFIC Foundation are earlier publications What is IARC?; How Red Meat Can Beef Up Your Nutrition; and Beefing up the Facts on Red Meat (infographic).
