You don't have to eat protein powder. The so-called protein powder, generally made of soybean protein, casein or whey protein, is used to supplement protein for people lacking in protein.

For the general healthy people, as long as they adhere to a normal diet, there is generally no shortage of protein. For example, milk, eggs, meat, soybeans, wheat, and corn all contain various essential amino acids in sufficient quantities and in appropriate proportions. As long as we insist on food diversification, we can meet the human demand for protein.

On the contrary, taking too much protein is not only a waste, but also too much protein will be converted into fat and stored in the body, which will have a certain adverse effect on the body.
