The World Health Organisation announced this week that eating just 50 grams of processed meat (less than two slices of bacon) a day increases the risk of bowel cancer by 18 per cent. They also found an increase of 100g of red meat a day increases the risk of bowel cancer by 17 per cent. They also found links between red meat and pancreatic cancer and prostate cancer, and processed meat and stomach cancer.

This breaking news came just two days after Viva!’s shocking footage revealed pigs crammed into tiny cages next to abandoned carcasses at Red Tractor farm that supplies Morrisons supermarket (see more here).

No wonder meat consumption is falling! R​ecent data from Defra shows UK meat consumption has fallen by 13 per cent since 2007.

Early this week 22 scientists from ten countries met at the International Agency for Research on Cancer (IARC) in Lyon, France, to evaluate the carcinogenicity of the consumption of red meat and processed meat. Their assessments were published on Monday.

The main findings

  • Overall, the Working Group classified consumption of processed meat as “carcinogenic to humans” (Group 1) on the basis of sufficient evidence for colorectal cancer. Additionally, a positive association with the consumption of processed meat was found for stomach cancer.
  • The Working Group classified consumption of red meat as “probably carcinogenic to humans” (Group 2A).
  • In making this evaluation, the Working Group took into consideration all the relevant data, including the substantial epidemiological data showing a positive association between consumption of red meat and colorectal cancer and the strong mechanistic evidence. Consumption of red meat was also positively associated with pancreatic and with prostate cancer.

Dr. Justine Butler
I joined Viva! as a health campaigner in 2005 after graduating from Bristol University with a PhD in molecular biology. My scientific training helped me research and write numerous reports, guides and fact sheets for Viva! including Meat the Truth, Fish-Free for Life, One in Nine (breast cancer and diet) and the substantial report on the detrimental health effects of consuming dairy; White Lies. This accompanied Viva!’s report The Dark Side of Dairy which spelt out the inherent cruelty of dairy farming. We were the first UK group to take on the dairy industry in this way, and many of our supporters go vegan after reading these reports.
