So scientifically speaking, vegans and even vegetarians(though less so) are usually undernourished, as their diet excludes many essential sources of protein. Now, I am no expert on diet, so correct me if I am wrong, but it would seem to be morally wrong to be a vegan, because you are depriving your body of key nutrients, and thus harming yourself. Of course if you have a health issue that prevents you from eating meat that is a different thing, but it seems that, especially lately, veganism and vegetarianism have been promoted to an extent previously unheard of. And I also understand that many of the (medieval) Saints almost never ate meat, but keep in mind that people were generally very healthy and hardy back in the old days, and their bodies did not have to contend with all the evil preservatives and chemicals added to our foodstuffs today. Also please do not reference that old and beaten to death argument: 'well when God created us we didn't eat meat, only vegetables and fruits.' That is false, because for one, we gravely strayed from God's original plan for us, and two, Jesus Himself ate meat and dairy. He also gave Adam dominion over all lower life forms. I personally think that to be a vegan is a grave sin against the 5th Commandment. Anyone have any thoughts?
