1, the disadvantages of long-term vegetarianism
1, long-term vegetarian diet is easy to fracture.
Studies have found that vegetarianism can reduce the risk of cancer, especially leukemia. This result has been confirmed in foreign studies. But if you don't know your physique, you will be blindly vegetarian and your body will light up with a red light. Studies have found that the bones of vegetarians are more brittle than those of meat eaters. "They have thinner bones, less calories and protein, lower body mass index and lower body fat content," the experts wrote in the research report. "They are at greater risk of fracture." A new finding is that young vegetarians are more likely to have eating disorders, and 1 1% of the respondents tend to overeat. More young vegetarians are seriously short of iron, zinc, calcium and vitamin B due to lack of guidance. They still think they are healthy.
2, long-term vegetarian menstrual disorders
From the physiological point of view of women, about13 of the respondents have menstrual disorder, and some women have anemia. Can women only eat vegetarian food? Because of the low fat intake and low estrogen secretion, these women's desires and fertility are greatly affected, and wrinkles are prone to occur, prompting women to accelerate aging.
3, long-term vegetarianism is easy to lack calcium
Although vegetarianism has many benefits, it can lead to iron deficiency anemia and calcium deficiency. Eating too many vegetables is also harmful. For example, spinach, vegetables, celery and tomatoes contain more oxalic acid, which is easy to form calcium oxalate stones when combined with calcium in other foods. This is also one of the reasons why many women who like vegetarianism are prone to lithiasis. At the same time, vegetarians often have insufficient intake of vitamin A and vitamin E. The lack of these two vitamins makes gallbladder epithelial cells easy to fall off, leading to cholesterol deposition and easy to form stones.
In addition, a complete vegetarian diet will lead to an imbalance in the proportion of food ingredients, resulting in insufficient intake of protein in animals. Even if plant proteins such as beans are supplemented, their absorption and utilization rate is far less than that of animal proteins. When protein, a vegan, doesn't eat enough, protein, carbohydrate and fat in his body will be out of balance, which will lead to decreased immunity, anemia and indigestion. The relevant departments conducted a special nutritional survey on some "monks", and the analysis results showed that they were basically malnourished to varying degrees, with weak immune function and easy to suffer from various infectious diseases.
For today's high-pressure white-collar workers, an occasional vegetarian diet can be used as a relief, but a long-term vegetarian diet is not the best policy.
2. Women should not be vegetarian for a long time.
1, childbearing age
If you are a vegetarian, you can lower estrogen levels and cause pregnancy disorders;
2. adolescence
Long-term vegetarianism will lead to substandard estrogen levels, stunted or delayed development of secondary sexual characteristics, hindering the development of women's breasts and gonads, and affecting women's physical beauty;
3, menopause
Due to ovarian atrophy, the production and secretion of estrogen in menopausal women are reduced or lacking. At this time, if you are a vegetarian for a long time, the symptoms of "menopausal syndrome" are particularly significant. Insufficient estrogen level can easily lead to osteoporosis, which is the bane of fracture.
3. How to be a healthy vegetarian?
If you choose vegetarian food for health, experts believe that you can eat animal food moderately and flexibly. The specific way is: on the basis of eating a lot of plant food, eat animal food in moderation according to personal circumstances, usually once a week, no more than three times at most. At the same time, animal food is mainly fish, and meat should be avoided as much as possible. Fish is rich in protein and unsaturated fatty acids, so it is healthier. The most important thing is to keep healthy cooking methods and pay attention to the diversification of food varieties in order to achieve a balanced nutrition.
4. The benefits of a healthy vegetarian diet
1, vegetarian skin rejuvenation and breath clearing
People who eat animal foods such as meat and eggs for a long time have increased acidic components in their bodies, exuberant sebaceous glands and oils, which are easy to make their skin greasy, have large pores, and have acne attacks, which will affect their beauty. Meat is rich in protein, and its metabolite is ammonia. This toxic substance not only damages the kidneys and makes the skin rough and dull, but also makes our breath and body gas lose freshness and smell thick and turbid. Being vegetarian for one day a week will reduce the intake of total fat, which will help protect the heart and lower blood pressure for a long time. Vegetarianism can also improve the acidic physique of meat eaters, reduce the acidic toxins in the blood, rejuvenate the human body and make the skin soft and shiny.
2. Vegetarian diet controls weight and excretes toxins.
Although "fat and thin" is beautiful, it is unhealthy to be too fat or too thin. Maintaining moderate curvaceous beauty is the dream of many female friends, and it is also the healthiest display of physical beauty. Eating high-calorie food for a long time, the weight rises linearly and the body grows horizontally, which is easy to induce various diseases such as hyperlipidemia and hyperglycemia. Being a vegetarian one day a week can help female friends who love beauty maintain a proper weight. Plant food is low in calories, belongs to alkaline food, and is rich in dietary fiber, antioxidants and healthy bioactive elements, which can promote human metabolism, help expel toxins from the body, and have the effect of slimming.
3. Vegetarian food is easy to digest
Vegetarianism mainly refers to eating habits based on vegetables, fruits, beans, grains, seeds and nuts. Wang Zhiyong, an attending Chinese physician in the Department of Gastroenterology, Liwan District Hospital of Traditional Chinese Medicine, said that these vegetarian nutrients are easy to digest and absorb, while meat is difficult to digest in the stomach. Even if it enters the large intestine, it is mostly undigested or only half digested. From the anatomical structure of the human body, the human intestine is similar to herbivores, but different from carnivores. The stomach acid of carnivores is 20 times that of humans, so the strong acid environment is enough to digest meat and bones. Experts believe that when animals are slaughtered, they will produce a lot of toxic secretions because of anger, fear, sadness, pain and struggle. People who eat this kind of meat will also eat toxins into their own bodies, increasing the load of detoxification organs such as kidneys and livers, making people prone to illness and aging. In addition, vegetarian food contains a lot of cellulose, which can stimulate intestinal peristalsis, facilitate defecation, make harmful substances in the body discharged in time, and reduce the stimulation and damage of harmful substances to the intestinal wall.
5. The health care function of vegetarian diet
1, lighter. Vegetarians are lighter than meat eaters because they reduce unnecessary fat.
2, reduce the risk of cancer. Studies have pointed out that meat is closely related to colon cancer.
3, there is no concern about parasites. Several parasites are transmitted to humans through infected meat.
4, longevity and longevity. According to nutritionists, vegetarians live longer than non-vegetarians. People in northern Pakistan and Indians in central Mexico are primitive vegetarians, and their average life expectancy is amazing. Buddhist monks also live long because of food.
5, reduce cholesterol content. Vegetarians always have less blood cholesterol than meat. If there is too much cholesterol in the blood, it will often cause blood vessel blockage and become the main cause of diseases such as hypertension and heart disease.
6. Reduce the burden on the kidneys. Waste from various higher animals and human bodies is brought to the kidneys through blood. Once the meat used by meat eaters contains animal blood, the burden on the kidneys becomes heavier.
7, easy to store. Plant protein is usually easier to store than animal protein.
8. The price is low. Vegetable protein is cheaper than meat.
9, in line with ecological principles. The land needed to produce one pound can produce ten pounds of plant protein. Many ecologists predict that the population explosion will force the whole world to be vegetarian.
10, with rich changes. Vegetarian housewives often find that using vegetable protein can cook excellent and delicious dishes better than using ordinary meat, and the cooking methods are varied, which can arouse good appetite.
