Anonymous: VENT:: Meat provides a vitamin b-12 that aids in cell health and development. It also provides a special type of protein and amino acids that break down easier. Though there are proteins in fruit and vegetables. You need the specific protein that only meat can provide the purpose of the creation of vegetarians and vegans is because ppl became aware of what happens to animals. Not cause healthier.
1. Vitamin B12 is the only known vitamin to be produced in nature exclusively by micro organisms— not by plants or animals. That’s correct. It ends up in animals and animal products because it’s digested.
2. It’s not only found inside animals digestive systems. However, if you look at the digestive system of cows, for example, they are not monogastric like us. Their stomachs have four parts and they rely on microbial fermentation to break down all that roughage they eat.
3. Our species does also have bacteria producing vitamin B12 in our digestive systems. If you ate no vitamin B12, you would still find it in your faeces. But it’s not absorbed where it needs to be, in your ileum, because it has go to through a process to get to the point where it can be used there. If we lived in nature, didn’t live quite as clean as we do now, and drank untreated drinking water, we would likely pick up the incredibly small amount of vitamin B12 that’s needed.
4. B12 from meat isn’t necessarily efficient. When you reach your 50’s, your doctor may advise you to supplement vitamin B12 because of changes in your body that make it more difficult to digest the vitamin out of animal products. I’ve read that if we lived long enough, eventually everyone would be vitamin B12 deficient. There are also other things that can complicate the digestion of B12.
5. Meat does not produce B12. It ends up in animal tissue only because the animals digest it. It mostly ends up in the liver, just as it does in our bodies. Some supplements even list dried liver as the source of their B12.
6. There are supplements of B12 made from the products of bacterial fermentation, without having to pass them through an animal to get it.
7. Believe it or not, with modern agriculture, you may be surprised to know that animals can be B12 deficient, and are fed cobalt in their dietary supplements or given vitamin B12. Don’t take my word for it. Take the word from the cattle industry.
"But while the rumen provides for much of the cows B vitamin requirements, many circumstances indicate a need for supplementation. The lack of a trace mineral, cobalt, can result in a vitamin B12 deficiency in cattle. This is because cobalt is a part of the vitamin B12 compound and is essential for rumen bacteria to manufacture this vitamin."
