World Vegan Day

I am not quite sure which practices the hon. Gentleman is referring to. If he is talking about the average lifespan of a dairy cow, that is something that I have researched and it is in the public domain. I know that DEFRA is looking to get the average lifespan of a dairy cow up to eight years, but six years was the average cited in the research that I looked at, while the figure for cows suffering from mastitis is 33%. I could go on—although I do not have the footnotes before me—but it is all in the public domain and well researched.

It can be quite difficult to nail down the facts and figures on the health benefits of a vegan diet, particularly when organisations such as meat marketing boards and milk marketing boards spend millions on counter-promotions. As I have mentioned, the recently released film “Forks Over Knives” puts the case that switching to a wholefoods-based vegan diet can prevent and even reverse serious illnesses. The film gives an overview of the 20-year China-Cornell-Oxford project, which found that a number of diseases, including coronary disease, diabetes and cancer, can be linked to the western diet of processed and animal-based foods. It is certainly true that the traditionally very low rates of breast cancer among Japanese women are increasing as they adopt western diets with a higher consumption of animal fats. In Japan, affluent women who eat meat daily have an 8.5 times higher risk of breast cancer than poorer women who rarely or never eat meat.

How would the hon. Lady respond to the statement by my GP and many others that we need a balanced diet, and that a balanced diet should include meat?

[Kerry McCarthy]

I will come to that in a moment. The World Cancer Research Fund carried out an authoritative study which found that people should avoid processed meat altogether, and eat red meat in moderate amounts only. That is the most authoritative study that I have come across. Cancer Research UK is co-funding a massive study called EPIC—the European Prospective Investigation into Cancer and Nutrition—which has found that people who ate two daily 80-gram portions of red or processed meat increased their risk of developing bowel cancer by a third, compared with those who ate just 20 grams a day. The same study found that people eating more than 100 grams of meat a day had over three times the risk of getting stomach cancer.

As I mentioned, the World Cancer Research Fund reviewed 263 research papers and concluded in May this year that there was convincing evidence that red and processed meat increased the risk of bowel cancer. When those findings emerged, the National Beef Association and the National Sheep Association, in conjunction with the National Farmers Union, issued statements accusing the fund of misleading the public. The fund retaliated by accusing the British meat industry of potentially defamatory and deliberately misleading statements, and repeated its message that it was best to avoid processed meat and to eat red meat only in moderation. It stated:

“The fact is that our report is the most comprehensive and authoritative review of the evidence that has ever been published and it found convincing evidence that red and processed meat both increase the risk of bowel cancer”.

As I have mentioned, there has been a significant rise in the number of people who are becoming vegan—[Interruption.]
