Protein is a very important nutrient, especially for growing children. The amino acid composition of protein in eggs, milk and meat is closer to human needs and easier to digest. Vegetarian, except bean products, the amino acid composition of other plant proteins is quite different from the proportion of human needs, and the efficiency of meeting human needs is also low. Even if you eat soy products, soy products themselves have a strong sense of fullness, and children will not eat many other foods if they eat too much, so they must have a single nutrition.
Vegetarians are also prone to lack of minerals: calcium, although dark green vegetables and tofu are also sources of calcium, but the amount needed is not small, and it is far less convenient to eat than dairy products; Although there are some iron and zinc in plant food, the absorption rate is low, which is not easy to meet the demand, and it is far less abundant than meat and has a high absorption rate. Among vegans, the problem of iron deficiency anemia is more serious, which will only do more harm to children and may affect physical growth and even intellectual development.
Vitamin B 12 is a nutrient that cannot be satisfied by vegan diet, because it almost exists only in animal food. And its lack is not easy to be detected, and it will be too late when the symptoms of lack appear. For children, vitamin B 12 is an important nutrient for their neurological development. Without VB 12, it will cause many serious problems, such as affecting the development of infants, causing pernicious anemia and irreversible nerve damage.
Choline is a water-soluble substance, which is very important for brain health, especially for fetal development. Choline produced by human liver is not enough to meet the needs of the body and needs to be supplemented by diet, and dietary choline mainly comes from meat, eggs and dairy products.
