Nowadays, everyone advocates health preservation, and many people think that eating meat will lead to three highs, and then they start to eat vegetarian. Some people even become vegetarians altogether, and they don't eat any meat at all, thinking that this will be healthier, but it is not right. Eating a vegetarian diet can reduce the intake of cholesterol and saturated fatty acids, and can also reduce the occurrence of some cardiovascular diseases and tumors, but long-term vegetarianism reduces protein intake, which is not good for the body.
The entire life of the human body is based on protein, and less protein synthesis will have an impact on overall health.
1. If you don't eat meat for a long time, your immunity will decrease.
Meat contains 8 kinds of amino acids that are essential for the human body, which is more suitable for human digestion and absorption. Moreover, the higher lysine content is more conducive to supplementing the deficiency of lysine in plant protein. Not eating animal protein for a long time can cause a decrease in immunity.
A long-term vegan diet will definitely make the human body lack trace elements such as vitamin B12, calcium, iron, and zinc, so that it will have many adverse effects on the human body.
2. Vegetarianism leads to decreased fertility.
Among the many studies on the effects of vegetarianism on female fertility, the conclusions of the Musberland Institute in Munich, Germany, are the most interesting. Professor Carl Buck of the college divided the healthy girls who participated in the trial into two groups, one of which was vegetarian except for a small amount of cheese and milk; The other group ate normal food. At the end of the 6-week program, the researchers found that 78% of the women who ate a vegetarian diet had a physiological phenomenon of stopping ovulation, and almost all of the group had shorter menstrual cycles than normal.
But in the group with a normal diet, 67% of women ovulate normally and there is no significant change in the menstrual cycle.
Under the condition that the weight of the two groups of subjects decreased by the same amount and they exercised the same amount, the reason why the women in the vegetarian group had the cessation of ovulation was related to the fact that the food they ate contained too little protein, which led to hormone secretion disorders and menstrual cycle disorders. In this way, she deduced that a vegetarian diet can cause abnormal reproductive function and even seriously affect reproductive ability.

Long-term vegetarianism can lead to protein deficiency, while protein deficiency in the human body can lead to anorexia, unfamiliarity, indigestion and a slender body; The wound is not easy to heal, the postpartum recovery is slow, and the recovery after illness is slow; followed by memory loss, neglect of learning and poor work efficiency; Low immunity, insomnia, dreams, low mood, fatigue, etc., vegetarians, especially vegetarians, do not even eat eggs, do not drink milk or do not eat meat, which can easily cause protein deficiency.
The main reason for the production of *** is that most plant foods contain very little protein and calories, and lack trace elements such as "calcium", "zinc" and "iron" required by the human body, and these elements are essential nutrients for human growth and development. This will lead to weight loss, indigestion, poor spirits, memory loss (increased probability of Alzheimer's disease) and decreased immunity. It is susceptible to various viruses and infectious diseases.
Risk of protein deficiency: Protein is an important part of all cells and tissues in the human body, composed of amino acids, among the 20 amino acids that make up natural proteins, there are 8 amino acids that cannot be synthesized by the human body, but must be obtained from food, lean meat, milk, eggs and fish and other feeds are the main essential amino acids for the human body, eating only vegetarian food for a long time will increase the risk of protein deficiency, leading to growth retardation, memory loss, low immunity, wounds that are difficult to heal and other problems.
Vegetarians do not eat meat, poultry, aquatic products and other feeds, which can lead to other diseases due to lack of nutrients. Plant foods are rich in vitamins, inorganic salts and organic acids, but lack of protein, fat, vitamin B, iron, zinc, etc., vegetarian diet will lead to incomplete nutrient intake, should avoid polyunsaturated fatty acids N-3, vitamin B12, vitamin D, calcium, iron, zinc deficiency. If necessary, nutrition can be supplemented, the absorption and utilization rate of iron in the feed is higher than that of plant food, vitamin B12 is almost present in the feed, milk is the main calcium **, the zinc content in seafood is high, and the feed is high-quality protein.

If you eat too vegetarian, it may lead to malnutrition, anemia, and decreased immunity for a long time, but it is generally rare to cause stomach cancer.
-
This statement is not very scientific, because there is no way to cause cancer by eating a vegetarian diet for a long time, that is, some fresh fruits and vegetables, so there is no scientific basis for this statement.

This statement is not scientific, and long-term vegetarianism is not the cause of stomach cancer. A vegetarian diet is good for your health. But long-term vegetarianism can lead to a lack of nutrients in the body. It is not carcinogenic.
