Most plant-derrived protein sources have an incomplete profile of amino acids. Humans have eight essential amino acids (amino acids that we must get from the diet as we cannot synthesize them) that are plentiful in animal sources and lacking to various degrees in plant sources. Plant sources of protein, even when combined to provide all the essential amino acids, are too heavy in carbohydrate, irritate the gut, and steal vitamins and minerals from the body via anti-nutrients.
- kondro 16y agoHence why the only semi-healthy vegans I know are those that cheat.
- rue 16y agoI wonder if naturally occurring animal deaths would be sufficient to provide meat for the planet otherwise living on a vegan diet?
- code_duck 16y agoSome people don't want to eat meat for ethical reasons, others because they think it's bizarre. Would you eat a dog, a horse, or another human if you didn't have to worry about the conditions of it's death? Probably not. Many vegans and vegetarians feel the same way about chickens, cows and pigs.
- code_duck 16y agoNo, the above comment is untrue. Scientific and dietary organizations have affirmed that vegan diets are perfectly healthy and sustainable. The only issue is B12.
- zackattack 16y agoSource? I'll take just one peer-reviewed article, please.
- awolf 16y agoCordain has done a lot of great research in this area: http://www.ncbi.nlm.nih.gov/pubmed/10489816 http://www.ncbi.nlm.nih.gov/pubmed/10489816
- code_duck 16y agoSo you combine beans and grains. That is how most of humanity exists, after all. I think the last part of your comment is patently untrue. The American Dietetic Association released a position paper stating that they believe vegetarian and vegan diets are perfectly healthy and sustainable. http://www.ncbi.nlm.nih.gov/pubmed/12826028 http://www.ncbi.nlm.nih.gov/pubmed/12826028
- awolf 16y agoOur knowledge of health is ever-changing. The ADA has been wrong before and will be wrong again. When this happens the ADA will simply revise its position. This is to be expected. This research has been around for 11 years and to my knowledge has gone unchallenged and mostly ignored: http://www.ncbi.nlm.nih.gov/pubmed/10489816 http://www.ncbi.nlm.nih.gov/pubmed/10489816 Just like the research showing that diabetic complications could be averted via normalizing blood sugars in the 1970’s or that gluten could actually be an allergen and that celiac disease is a real condition in the 1990’s. As a vegetarian or vegan you can definitely survive, but you won't thrive.
- code_duck 16y agoSome text about wheat hardly proves your assertions. That doesn't address how beans, nuts, etc. supposedly drain you of vitamins. Hundreds of millions of people are perfectly healthy eating vegetarian diets. You should turn your attention to people eating the typical American diet... surely they need it more than people who eat big handfuls of vegetables all day.
