The World Health Organization has added red meats – such as pork, lamb and beef – and processed meats to its list of cancer links. Processed meats have been put in the same Group 1 list as tobacco, asbestos and diesel fumes. WHO says there’s an increased risk of colon cancer with higher consumptions of such meats. Beef, pork and lamb have been classified as ‘probable’ carcinogens. They’re in the Group 2A list, which includes glyphosate – the active ingredient in weedkillers. The evaluation comes a a result of more than 800 studies from several continents. Meat industry groups argue that cancer is not caused by specific foods but by several factors. Doctors and government agencies have long warned that a diet loaded with red meat is linked to cancers.
