Eating vegan food for a long time will cause anemia and tumor, which will unbalance the proportion of carbohydrate, protein and fat in human body, lead to indigestion, memory loss, decreased immunity, endocrine and metabolic dysfunction, and easily lead to anemia and tumor.
Long-term vegetarianism can also lead to a decrease in gastric acid and digestive enzymes, a decrease in taste, and loss of appetite.
Peroxides that accelerate aging produced by unsaturated fatty acids in vegetable oil combine with human protein to form lipofuscin, which will accelerate aging when deposited in organs.
Trace elements such as zinc, calcium and iron, which lead to the deficiency of trace elements and vitamins, mainly come from diet; 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.
