Easy to digest and absorb
Compared with meat, vegetarian nutrients are more easily digested and absorbed by the body, meat is not easy to be digested, even in the large intestine when there is still most of the undigested, these residual food decay fast, and with toxicity, which is very harmful to health; and vegetables, fruits, coarse grains of food nutrients are easier to digest, and some of the nutrients can be directly absorbed by the body, vegetarian dishes in the Fiber can also effectively prevent constipation.
Eat vegetarian to enhance appetite

Long-term vegetarianism causes insufficient intake of animal protein
Long-term vegetarian food refuses to meat dishes, easy to cause insufficient intake of animal protein, although supplemented with plant protein, but the absorption and utilization of plant protein is far less than animal protein, when long-term vegetarian diet leads to insufficient intake of animal protein, the body's protein, fat and carbohydrate imbalance, it is easy to cause immunity and memory loss, anemia, indigestion and other diseases.
Long-term vegetarianism leads to loss of minerals
Soy, vegetables and grains are rich in dietary fiber, which on the one hand can promote digestion, on the other hand, dietary fiber has a slow laxative effect, which can promote intestinal peristalsis and reduce the time for intestinal residues to pass through the intestine, but too much dietary fiber will accelerate the discharge of mineral nutrients in the gastrointestinal tract, resulting in the loss of minerals in the body before absorption, which is not worth the loss.
Long-term vegetarianism leads to zinc deficiency
The zinc intake of long-term vegetarians is much lower than that of non-vegetarians, and long-term zinc deficiency can easily affect the development of children, as well as their immune and sexual functions. The bioavailability of plant zinc is generally low, so vegetarians should pay attention to the intake of zinc and eat more zinc-supplemented foods. Vegetarians may want to eat more zinc-rich foods such as soy products, nuts or natural grains and mustard greens.
