On the topic of vegetarian diets, I'm a pretty liberal guy and I don't really care if someone wants to try to subsist on a diet consisting only of fruit and vegetables. Generally, I get my health advice from my doctor who told me in no uncertain terms that human beings are
omnivores. It is possible to survive on a meatless diet, but it's not natural and must be supplemented with proteins at the very least.
I got this from Google and I think it puts veganism in the proper perspective:
Humans are classic examples of omnivores in all relevant anatomical traits. There is no basis in anatomy or physiology for the assumption that humans are pre-adapted to the vegetarian diet. For that reason, the best arguments in support of a meat-free diet remain ecological, ethical, and health concerns.
As I have aged I've developed less of a taste for meat. That is only exacerbated by the massive scale of suffering and agony inflicted upon otherwise innocent animals that only want to live out their lives as we do. As an animal lover I don't like to think about where that hamburger or steak came from and I know it's blatantly hypocritical to say I'm an animal lover in one breath then say I love steak and hamburgers in the next.
It is an ethical dilemma that I've struggled with many times. I've even gone long periods of time -3+ years at one point in my 40's- without eating any meat. Back then, when asked why I was abstaining I would usually cite my ethical problem with animal cruelty in the slaughterhouses and on non-dairy cattle farms where they raise cattle for slaughter. I have seen the suffering first-hand having supplied day laborers to a slaughterhouse in Turlock, CA back in the 90's when I lived in Modesto, CA. To this day I still have not seen that level of suffering anywhere. It was around that time that I started to consider giving up meat.
If it were not for the fact that my doctor strongly cautioned me not to do it I'd probably be a vegetarian today. Red meat he said I could do without, but he advised that I keep seafood and chicken in my diet otherwise I'd probably need some kind of supplements and I already take so many fucking pills every day I sound like a baby rattle when I move
