Protein food is also known as food containing high protein content, including animal high protein food, plant high protein food, common beef, lamb, soybean, etc.. Protein foods are divided into animal protein foods and plant protein foods. Animal high protein foods are commonly found in beef (19.9g/100g), lamb (19g/100g), pork (13.2g/100g), eggs (13.3g/100g), and milk (3g/100g). Plant-based high protein foods are commonly found in tofu, which contains about 8.1g of protein per 100g. All these foods are protein foods that can fulfill the body’s need for protein. Normal people need to consume a certain amount of protein every day, but if a large amount of high protein food is consumed for a long period of time, it may have certain effects on the body, so moderate intake of protein is needed.
