I am writing in response to your article that contains criticism of the World Cancer Research Fund cancer prevention report for which I was project director (The Grocer, 17 May, p30). The article mentions how individual research projects are given too much weight by the media and I agree with this general sentiment wholeheartedly. But I think it is unfair to talk about our report in this context because it was not just another study. It was the most comprehensive analysis of the evidence on cancer prevention ever published, and was a synthesis of many thousands of studies. And based on independent expert judgement of all the evidence, it includes 10 recommendations for preventing cancer. Just one of these was to limit red meat consumption and to avoid processed meat. Much of the media coverage focused on this one recommendation, but the recommendations need to be taken as a package representing an overall shift in dietary pattern, and not taken singly. In the article, Chris Lamb (marketing manager of beef and lamb body Eblex) describes our advice on processed meat as "over the top". In fact, the science is clear that if people are concerned about cancer then the best amount of processed meat to eat is none at all. I am confident the report's recommendations are the best advice available for reducing the risk of cancer through food, nutrition and physical activity.
