But protein isn’t all we get from meat. For instance this is also a great source of oils and fats, and while we’re largely told to avoid fat in high quantities getting at least some is actually crucial to our diet.

At the same time we also get vitamin B12 from meat and this is the only source of it other than dirt in the ground. B12 is actually a crucial substance and deficiency can cause serious problems such as nerve damage, low energy and problems utilizing calcium which can lead to osteoporosis. We become omnivorous in order to help develop our brain function.

I personal believe human are omnivorous, even gorilla and fish eat meat to survival as natural. God created us this way, thus live on it. It’s not merciless to eat other living beings; our human just part of the food chain. And yes we are human and some how part of people believe that we should be more advanced or ethical. I think that I honor those who have compassion of animals。However, we don’t need to be cruel to the animals, but we need meat to supply our body needs as human nature.

At last, many vegetarian like to say that people who only eat vegetable are healthier and less disease than people who eat meat. Well, it’s because those people eat meat don’t know who to balance their diet, but not because they eat meat. Meats have more calories, but also give people a comprehensive nutrition.
