1. leads to anemia and tumor.
Eating vegan food for a long time will unbalance the proportion of carbohydrate, protein and fat in human body, which will lead to indigestion, memory loss, decreased immunity, endocrine and metabolic dysfunction, and anemia and tumor are prone to occur.
2. lead to loss of appetite
Long-term vegetarian diet can also lead to a decrease in gastric acid and digestive enzymes, a decrease in taste, and loss of appetite.
Accelerate aging
Peroxides produced by unsaturated fatty acids in vegetable oil combine with protein to form lipofuscin, which is deposited in organs and will accelerate aging.
4. Lead to the lack of trace elements and vitamins.
Trace elements necessary for human body, such as zinc, calcium and iron, mainly come from eating; Zinc mainly comes from animal food; 80% of calcium in the diet comes from milk; 80% iron comes from meat and eggs. Vegetarian food contains less zinc, calcium and iron, but more phytic acid and oxalic acid, which will hinder the attraction of trace elements such as zinc, calcium and iron. For example, oxalic acid contained in spinach can be combined with calcium in tofu to form calcium oxalate, which is not absorbed by the human body. Long-term vegetarians are prone to diseases caused by trace element deficiency: (1) zinc deficiency can cause sexual dysfunction and infertility in adults. Recently, medical research on vegetarianism has confirmed that women's frequent vegetarianism will have a destructive effect on hormone secretion in the body and may even lead to infertility. If women don't want their fertility to be affected, they must think twice before acting, especially women over 30, whose fertility has declined, so they should be more cautious. (2) Zinc deficiency can cause anorexia and pica in children. (3) Calcium deficiency can cause rickets in children, hyperosteogeny and osteoporosis in middle-aged and elderly people. (4) Iron deficiency can cause anemia and affect children's intellectual development. 5. Causing gallstones: Long-term vegetarianism will increase the risk of gallstones, especially for the elderly. Studies have proved that nearly half of the elderly patients with gallstones are caused by a simple vegetarian diet. 6. Not conducive to blood pressure: Some people think that eating meat will lead to an increase in blood pressure, so they are strictly vegetarian and refuse any meat. In fact, this is not only bad for the health, but also bad for the control of hypertension. Eating meat and eggs can increase the nutrition of blood vessels and maintain their good elasticity. Strictly vegetarian, do not eat any meat, refuse all animal protein and fat intake, the result is poor vascular elasticity. Experts pointed out that if the blood lipid is high, it can be discharged through drugs. If the elasticity of blood vessels deteriorates, it will be difficult to recover. Poor blood vessel elasticity will lead to high blood pressure.
