Protein is an essential nutrient for human body, so we should pay attention to the intake of high-protein food in our daily life. High-protein foods, one is animal protein such as milk, livestock meat, poultry meat, eggs, fish and shrimp; The other is soybeans, beans such as soybeans, green beans and black beans, and plant proteins such as sesame seeds, melon seeds, walnuts, almonds and pine nuts. Because the types and proportions of amino acids contained in animal protein are more in line with human needs, the nutritional value of animal protein is higher than that of plant protein.
