First of all, it leads to the lack of protein in human body.
Although some plants also contain a lot of protein, such as high-protein plants such as soybeans, compared with the protein needed by human body, the protein contained in plants is far from enough, and the protein contained in plants is more difficult to be absorbed and digested by human body than animal protein.
Second, it causes the human body to lack some vitamins.
If you don't eat meat for a long time, you can't get enough fat-soluble vitamins. Fat-soluble vitamins refer to vitamins that are insoluble in water and generally soluble in animal oil, such as vitamin A, vitamin D, vitamin E, etc. The lack of these vitamins will lead to the decline of human immunity, resulting in dry and rough skin, making people prone to diseases such as osteoporosis. Therefore, not eating meat for a long time is harmful to the body, and may even lead to human diseases and threaten people's health and safety.
Third, it leads to the lack of trace elements in the human body.
Meat also contains many essential trace elements, such as iron, zinc, calcium and magnesium. Although plants also contain a certain amount of trace elements, they are far less than meat. If you don't eat meat for a long time, it will lead to the lack of these trace elements, and plants contain oxalic acid and other substances, which will hinder the absorption of iron and other elements, thus causing iron deficiency anemia, osteoporosis and other problems, threatening human health.
Fourth, hormone secretion disorder.
Hormone secretion in the human body is inseparable from the raw material of fat. Not eating meat for a long time and taking too little fat will lead to insufficient raw materials for hormone secretion, which will affect the secretion of female estrogen, cause symptoms such as irregular menstruation and infertility, and even accelerate human aging.
Fifth, people are prone to stones.
People who don't eat meat for a long time but only eat vegetarian food are prone to stones, because oxalic acid contained in plants will combine with calcium in the human body, thus producing stones; At the same time, the lack of vitamin A and vitamin E is also one of the reasons for getting stones easily.
It can be seen that not eating meat for a long time is very harmful to human body, especially to children and lactating women. A reasonable diet structure is the correct living habit. Only by combining vegetarian food with meat can we supplement all the substances needed by the whole human body and make people have a healthy body.
