This is not about being vegan or vegetarian. At one point in the film it pokes fun at how unhealthy vegans/vegetarians can be...eating potato chips and drinking coke can be vegan. This was about a lifestyle choice to eat more plant based foods and more likely avert the many chronic metabolic syndromes that have become far too common. It's tough to make the change, but I've recently tried it, eat all I want, and have lost ~30 lbs so far. After 15 yrs my total cholesterol is finally under 200 as well as most other numbers greatly improving, and this has happened after only a couple months of eating this way. Simple choice is to eat better and feel better, or to one day have a great chance of being forced into taking an assortment of pharmaceuticals with all their costs and lovely side effects. This lifestyle may not make you live longer, but your quality of life will be much better.
