People who are vegetarian for a long time will lack vitamin B 12, which will lead to thickening of the inner wall of arterial blood vessels and arteriosclerosis. Vitamin B 12 needed by human body is mainly obtained from meat, eggs or milk. If you are a vegetarian for a long time, eat less eggs and drink less milk, and don't eat vitamin tablets at ordinary times, after 5 to 6 years, your body will lack vitamin B 12, leading to anemia.
Insufficient vitamin B 12 can also lead to fatigue, irritability, loss of appetite and memory loss. In addition, vegetarian dishes are often rich in oil and salt, which easily leads to high blood pressure in vegetarians.
The analysis results show that people who don't eat meat for a long time basically have different degrees of malnutrition, weak immune function and are prone to various infectious diseases. This is related to people's aging, hair whitening, tooth loss, osteoporosis, cardiovascular diseases and so on.
Manganese deficiency not only affects bone development and cannot meet the needs of metabolism, but also causes bone pain, fatigue, hunchback, fracture and other diseases. Manganese contained in plant food is difficult to be absorbed by human body, and only manganese contained in meat food is easy to be absorbed by human body.
People need a lot of protein and fat every day to stay energetic, and meat products just supplement this deficiency of vegetarian food.
In addition, there are more plant fiber components in vegetarian diet, which can reduce the reabsorption of cholic acid and the concentration of bile salts. Furthermore, vegetarians often have insufficient intake of vitamin A and vitamin E. The lack of these two vitamins makes gallbladder epithelial cells fall off easily, which leads to cholesterol deposition and stones.

3. Pregnant women and wet nurses.
They should take nutrition for themselves and their babies and eat more meat.
4. Children and adolescents.
