I came across VSH about a year ago. They regularly post hour long videos on veganism. I love it that their name is vegetarian but they promote veganism. I guess they decided to stick with the original name, since they go back a long way.
The themes of their talks cover the many angles of health. What has prompted me to post this is one entitled "Why Vegan? How a Vegan Diet Can Save Your Health and Money" by a guy called Hesh Goldstein who I have not heard of before. He pulls no punches in showing how the dairy and meat industry own the food messages coming out of government. He talks about the vast subsidies that keep meat & dairy cheap. He talks about how the whole economic system is built on keeping people ill. Of course much of this video is US based but its messages I think have so much relevance in the UK and the rest of the world as well.
