For health, all you need, believe it or not, is 20 to 40 grams of protein per day. Remember that your body manufactures all but 9 amino acids, and people survive as vegetarians.
Now, I don't believe that Humans were made for vegetarianism. The evidence? There are some vitamins, like B 12, that are only present in animal-derived foods, and several minerals, like Iron, Zinc and Magnesium, which are poorly absorbed from vegetable sources. This is prima fasce evidence that Humans are not herbivores. This might have been true for our ape-like ancestors from 5 million years ago, but it has not been true for at least 50 000 years since Humans became hunther-gatherers and started to eat not only plants but also eggs, milk and game meat.
Having said that, I believe that meat is completley unnecessary for health: eating some slices of cottage cheese or a few whole eggs a week will give you all the amino acids that you need. Meat is
overload. If your goal is to gain muslce, then meat is extraordinary since it gives you lots of complete protein. However, if you're just into fintess and health and want to be as healthy as possible, then the ideal is to become a non-meat, non-processed food eating omnivore.
