How is this at all the same thing? Having to use a manufactured pill to supplement the nutrients you're missing out on by limiting the variety of your diet is in no way a plausible solution. We eat animals because, in the end, we want to survive and animals are made from a very important chemical that every fleshy creature needs, Amino Acids. Don't tell me that just because I can get the same thing from a pill, I should stop eating something that gives it to me naturally, especially if you're only real reason for your argument is that some pig somewhere has a cute face.
