Long-term vegetarianism will lead to the deficiency of protein, calcium, iron, zinc and vitamin B 12. Although beans contain a lot of plant protein, calcium, iron and zinc, dark green vegetables contain a lot of calcium and iron, and whole grain products contain a lot of zinc, they are often entangled with phytic acid and other molecules, and their absorption efficiency is relatively low. In the long run, it will lead to the decline of human immunity and lead to various diseases, including iron deficiency anemia, osteoporosis, senile depression, gallstones and so on. , but also affect reproductive function.
The American Association for Cancer Research argues that it is more appropriate for more than two-thirds of food to come from plants, which is conducive to reducing the risk of cancer.
Second, the tip:
Completely vegetarian is unscientific.
Food without meat and fish ingredients may not have healthy value. Only vegetarianism, as far as possible in the form of natural food intake, the proportion of processed food is very low, in order to have a healthy effect. On the other hand, vegetarians must mix all kinds of plant foods well to ensure a comprehensive and balanced nutrition in all aspects.
Vegetarian food does not necessarily become a healthy diet. Vegetarianism also has the problem of nutritional balance. If not properly matched, not only can not get enough nutrition, but also can not necessarily reduce the incidence of diseases or bring slim figure.
Extended data
Six kinds of people should not refuse to eat meat:
1, anemia patients and menstrual women
Anemia is mostly due to the lack of protein and iron which are rich in meat. Therefore, people with anemia must eat meat, preferably red meat such as pork, beef and mutton. Women should also eat meat during menstruation.
2. Pregnant women and nursing mothers
Pregnant women and nursing mothers should take nutrition for themselves and their babies and eat more meat.
3, trauma or surgery patients
The human body is made up of protein. People like trauma patients and surgical patients need a lot of protein, because they need the growth and healing of organic tissues, and the best way to supply protein is to eat meat.
4. Children and adolescents
Children and adolescents are in the stage of growth and development, and the synthesis of protein should be greater than the decomposition. Therefore, we must use enough meat to ensure the supply of protein and ensure the energy needed for development.
Old people over 5.65 years old
People over the age of 65 begin to relax, and protein can delay muscle loss. If you don't like meat, you might as well use eggs or dairy products instead.
6. People who are losing weight
Many people who are losing weight won't eat meat on the grounds that it is rich in fat. However, we can know that protein can improve satiety and reduce the amount of starch to achieve the effect of weight loss, so we should slightly increase the intake of protein when losing weight.
