World Vegan Day

Simon Hart Excerpts

Tuesday 1st November 2011 Commons Chamber

[Kerry McCarthy]

I agree entirely with my hon. Friend, and I will come to the environmental and food security case for being vegan in a moment.

[Simon Hart (Carmarthen West and South Pembrokeshire) (Con)]

Can the hon. Lady point to any peer-reviewed science to support her allegation about the UK livestock industry, rather than giving us the mantra of the animal rights or vegan movement? If she can do that, her argument might carry a bit more weight.

[Kerry McCarthy]

I am about to cite some scientific research on the health case, and I also have some very authoritative sources for the environmental case. The ethical case is about people’s personal opinions on whether it is ethical to treat animals in such a way or to eat them. It is not science-led; it is led by people’s morals.

[Simon Hart]

So is the hon. Lady saying that the assertions she has made about agricultural practices are a personal opinion, as opposed to there being any evidence to support them?

[Kerry McCarthy]

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.
