What is vegetarian health? What food does vegetarian food mean?

At present, more and more people in the world choose to be vegetarian. It seems fashionable to tell others that you are a vegetarian. According to statistics, about 5%-9% of American adults are vegetarians. In addition, the retail sales of vegetarian food in the United States is also growing at a rate of 20%-40% every year. Besides religion, environmental protection and weight loss, the most respected reason for vegetarianism is health preservation. Vegetarian food looks clear and light, and it will definitely be good for your health, which has become the knowledge of many people. Is this understanding reasonable? There are many ways to be vegetarian. What is a vegetarian? The reporter learned from nutritionists that vegetarianism mainly refers to the eating habits based on plant foods such as fruits, vegetables, beans, grains, seeds and nuts. Strict vegetarians don't eat meat, including fish, shrimp and poultry, and don't eat any animal by-products such as eggs and milk. For example, there is an American-made Washington brand red apple, which looks shiny and attractive, but some vegetarians give up eating it because its luster comes from shellac extracted by insects. However, such a strict vegetarian is, after all, a minority in life. Most people will choose to be a dairy vegetarian who can eat dairy products, or a dairy vegetarian who can accept egg and milk foods. There is also a vegetarian who usually chooses to eat vegetarian food several times a week. This is the case with Ms. Sharon, a yoga instructor known to the reporter. She chooses a vegetarian diet based on vegetable salad and fruit for dinner every day. According to statistics, most people with vegetarian preferences in the United States will choose to be vegetarian more than four times a week. Better than meat eaters, the American Dietetic Association once expressed their view that vegetarian food is good for health. Because a large number of studies on vegetarians in the United States show that their mortality from some chronic diseases, such as obesity, diabetes, colon cancer and hypertension, is indeed lower than that of meat eaters. The main reason for this result is that vegetarianism increases the intake of plant fiber and carbohydrate, reduces the intake of whole fat, saturated fat and cholesterol, and improves the metabolic process of vegetarians. In addition, being a vegetarian does not mean being thin. Many studies have confirmed that vegetarians are stronger, more agile and more persistent than meat eaters. Dr Irving Fisher of Yale University once called 32 vegetarians and 15 non-vegetarians to carry out the arm-lifting test, and found that only 2 non-vegetarians held their arms for more than 15 minutes, while 22 vegetarians exceeded this standard. Vegetarians tend not to feel tired easily. This is because the body fluids of normal people are weakly alkaline, and the fat and protein in meat will produce acidic substances after decomposition, which will stimulate human tissues and organs and make people feel tired. However, vegetables and fruits are mostly alkaline foods, which is conducive to maintaining the balance of pH in the body and eliminating fatigue. However, nutritionists also remind you not to think that you can lose weight by being vegetarian. Many fruits in vegetarian diet have high sugar content, but nuts are high-fat foods, which still make people fat. Vegetarianism should be gradual. The most important thing for vegetarians is a balanced diet. American medical experts point out that vegan diet can't get vitamin B 12 which can only be obtained from meat food, which will lead to bad consequences such as memory loss. On the other hand, Ms. Sharon said that her doctor did not support her completely rejecting meat and poultry, and thought that only by adhering to the dietary principle of combining meat and vegetables would the nutrition be more comprehensive. If you choose vegetarian food completely, you should have regular physical nutrition tests and take some necessary dietary supplements. In addition, nutritionists also remind that vegetarians should eat as much unprocessed or unprocessed grains as possible. For newcomers who want to join the vegetarian team, the transformation process should be gradual, gradually reducing meat and preventing malnutrition.
