How much meat should you eat all day?
According to the US Department of Agriculture (USDA), adequate meat intake is about 2-3 ounces per dish, looks like a card deck. If someone has a stake, how many people eat meat as the deck size of the card? – Almost none. Most stakes provided at restaurants are about 2 to 4 times larger than that.
One of the biggest reasons people eat meat is due to protein. From birth to about one year old, it is growing fastest throughout his lifetime. So breast milk may absorb that it has a lot of proteins naturally. Indeed, breast milk has about 6% protein. There are not so many things people assumed. Most vegetables and fruits have more proteins.
Even bodybuilders who think that they need a lot of protein to enhance muscle must consider protein intake again. Bodybuilder champion Arnold Schwarzenegger said, "I think that 50 to 70% of the protein intake in the total caloric intake is necessary to gain weight, but that is not the case."  Since 1 kg is about 2.2 pounds (exactly 2.2046226218 pounds), if weigh 150 pounds, 150 / 2.2 = 68.18 kg. Therefore, 68.18 grams of protein are required. How much is it? One ounce is about 28.3 grams. So 68.18 / 28.3 = 2.4 oz. Approximately 2.4 ounces of protein is required per day. The recommended meat intake of USDA is about 2-3 ounces per dish, and it looks like a card deck.
However, plants already contain that amount of protein. If you eat too much meat, if you eat the majority of Americans, it will make your blood acidic due to too much intake of protein causing bone calcium loss.
People usually believe that humans think that we eat meat because we believe that we are always and omnivorous. That is not true. Meat was not a major part of human diet. They invented a tool to kill animals. It is not so long. It may take a long time of tens of thousands of years, which is a short moment of an evolutionary scale timetable.
Looking at human diet from the evolutionary scale, humans are primates. All primate meals are 95-99% raw fruits and vegetables except for humans. When food is offered to children who have not yet developed food poisoning, despite the fact that the gourmet cuisine prepared by the top chief is right next to them, their natural choice is fruitful. Every primate likes fruits naturally including humans.
Of all the primates, no one eats meat like a human being. Gorilla is 100% vegetarian. Orangutan eats a small amount of insects, Bonobos eat meat, but less than 1%. Chimpanzees eat less than 5% of the meat in the meal. Nevertheless, all of these primates, dogs are sharper and longer than humans.
Examining the anatomy of the body, most humans are "behavioral" omnivores, but humans are certified herbivores. Herbivorous animals and humans need to chew by spreading the mouth movement to the left and right before swallowing. Carnivores and omnivores swallow the whole food without chewing too much. Creatures like pigs drink whole body including skin, when eating fruits such as banana, but primates always peel fruits when eaten.
Among primates, diabetes, arthritis, cancer, hypertension are not seen. You only see it in human society. Interestingly, you see the same disease when you give an animal diet to a herbivore. Incidentally, clinical trials have shown that when herbivorous animals switch to human diet, they are suffering from diseases that modern people suffer, such as diabetes, cancer, hypertension, heart disease, arthritis.
The recommended amount of USDA meat is about 2-3 ounces per serving. I would say that the proper carnivorous meat should not exceed 5% of human diet.
