China people, who always pay attention to food, pay more attention to vegetarian food, fruit and light food with the improvement of their living standards. Many big cities, such as Beijing, Chengdu, Guangzhou, Harbin, Shanghai, Xi 'an and Hangzhou, have already established vegetarian restaurants and restaurants, and their business is booming. Vegetarianism has been popular in western developed countries for many years. Long-term research in scientific and medical circles has confirmed that vegetarian diet is of great benefit to human health. Some experts pointed out that this century is a vegetarian era that advocates nature, health and practices human environmental protection.
A light and simple diet can reduce the incidence of diseases. It has been thought that carnivores are fierce and strong, so it is inferred that it is good for people to eat more meat. In fact, this is a big misunderstanding. The ancients said: if you want to live forever, you should be clear in your intestines. Experts pointed out that the intestines of animals are very short, and the absorption and excretion cycle after eating meat is also very short. However, human intestines are much longer than animals, so it is impossible to discharge the waste after eating meat in a short time, which may pollute the internal organs and cause diseases. Eating more meat will cause acidic blood. According to clinical observation, 7% of human diseases occur in acidic constitution, such as hypertension, heart disease, stroke and so on. After studying the food composition of seven countries, scientists found that the countries with the highest meat consumption have the highest coronary heart disease and mortality, while vegetarians have relatively low coronary heart disease and mortality.
Huangdi Neijing said: "The change of paste beam is full of boils, which means that people who eat fishy fish and paste beam with thick taste for a long time can give out big boils on their bodies, and the possibility of getting sick is as easy as holding an empty container to accept things. Experts generally believe that vegetarian food is rich in nutrition, delicious, clean and hygienic, which helps to reduce the blood fat content of human body and avoid the pathological changes caused by improper cooking of meat. It is an inevitable result that vegetarians will live longer with less diseases. According to an investigation report, in 1985, three departments of Shanghai Eighth Five-Year Hospital conducted a comprehensive physical examination on 1 vegetarians and 1 meat eaters in Shanghai and Suzhou. As a result, the blood viscosity of meat eaters was much higher than that of vegetarians. Among the 1 vegetarians, only 18 people suffered from cardiovascular diseases, while 67 vegetarians, 57 vegetarians without diseases, and only 8 vegetarians without diseases. As we all know, high blood viscosity is the cause of coronary heart disease and various chronic diseases.
Therefore, vegetarian diet has the following effects on human health: First, it can prevent hypertension. Some people have checked the blood pressure of most vegetarian Mormons and found that their blood pressure is 4-5 degrees lower than that of meat eaters. After some people stop eating meat for a few months, their blood pressure will drop slightly by 3 degrees, but if they resume eating meat, their blood pressure will return to its original state within a few weeks. Second, it can lower cholesterol. Vegetarian food contains less cholesterol than meat food, while vegan food contains no cholesterol at all. The blood cholesterol content of vegetarians is lower than that of ordinary people, while vegan food is the lowest. Harvard Medical School once conducted an experiment on vegetarianism. If vegetarians eat half a pound of beef a day, their cholesterol will soon increase by 19%, and their pulse will also accelerate. When the experiment is terminated and they return to vegetarian diet, their cholesterol will return to its original state within 1 to 14 days. After a follow-up survey of 1,1 subjects by the British medical community, it was found that if cholesterol and blood pressure were properly controlled, heart disease could be effectively prevented, and the rate of heart disease among vegetarians was much lower than that of meat eaters. Third, vegetarians are not prone to cancer. Scientists have confirmed that all kinds of cancers are related to diet structure. Long-term high-fat diet will promote thymus atrophy and inhibit the immune function of lymphocytes. People's continuous intake of high-fat food will only increase the incidence and mortality of breast cancer, intestinal cancer and prostate cancer, while vegetables and fruits contain inexhaustible anti-cancer factors. A survey by scientists found that the number of people suffering from cancer in Shanghai in the United States is four to seven times higher than that in China, which is probably directly related to the American high-fat diet. Fourth, vegetarianism is not easy to suffer from gallstones. Medical experts from Oxford University in the United Kingdom have experimented with 7 vegetarian women, and the conclusions are as follows: their probability of suffering from gallstones is only half that of the average person; Fifth, vegetarians are not prone to diabetes. Relevant research reports point out that meat or fat will interfere with insulin metabolism, so vegetarians are not easy to get diabetes, and a survey of 25, experimenters for 21 years has completely confirmed this point. Sixth, vegetarians are not easy to suffer from osteoporosis. After menopause, the function of bone remodeling will lead to osteoporosis due to obvious degradation, but research shows that the speed of mineral loss in bones of vegetarians is only half that of meat eaters.
Sun Yat-sen, a pioneer of modern revolution, once played a very good role in the article "China people should keep China's diet law". He said: "China is not only rich in food inventions, but also beautiful in cooking methods, which is beyond the reach of other countries, while China people's diet is still good, which coincides with scientific hygiene, especially the average person in other countries. China people often drink green tea, eat light rice, and add vegetables and tofu. These foods are tested by today's hygienists as the most beneficial to health. Therefore, people in the hinterland of China, who eat less than wine and meat, often live longer. " Here, Sun Yat-sen has clearly explained the causal relationship between longevity and light diet. Then, he turned his pen to tofu in vegetarian diet, and tofu is the meat in real plants. This thing has the power of meat, but it is not poisonous. Therefore, China is vegetarian all over the country and has become accustomed to it, not waiting for scholars to advocate it. " The most significant thing is that he also compared the advantages and disadvantages of Chinese and western eating habits: "People in Europe and America drink turbid wine, and the people who eat it smell fishy, and they also learn from each other. Therefore, although science was advocated in the past, laws were severely banned in the future, such as the strict prohibition of alcohol in modern countries such as Russia and the United States, which could not be transferred for a while." As far as diet is concerned, China's practice is superior to other countries, which is the most important thing in life. However, it is a great blessing for China people to be able to become natural in Xi Zhi. "
The benefits of vegetarianism to human body are shown in the following aspects: First, vegetarianism is good for people to feel refreshed and calm. Especially for those who practice martial arts and qigong, they can get into silence faster and better, thus achieving the purpose of benefiting body and mind and prolonging life. Second, vegetarianism can enhance the resilience of patients as soon as possible. Relevant data show that vegetables are not only rich in vitamins, but also contain minerals necessary for human body, which have the functions of disease prevention and medical care.
If the frail children can eat more vegetables, beans, fruits, kelp and milk, their health level can be obviously improved. Third, vegetarians have good physique, agility and endurance. Vegetarian's blood is pure, blood viscosity is low, and the blood can circulate freely in the viscera, so that all parts of the viscera will not be diseased due to blockage, the viscera will become strong, and other organ systems will naturally be healthy. Therefore, vegetarians are in good health, are not prone to sudden pathological changes, are easy to be emotionally stable, and have a well-proportioned posture. No meat eaters consume excessive fat, and protein is stored in the body, which makes them appear to be sluggish and faltering. Most people are skeptical about whether vegetarians can achieve excellent results in the sports field. In recent years, a large number of reports show that vegetarian athletes are slightly stronger in physical strength and endurance than meat-eating athletes, such as vegetarian athletes Murray and Maureen Ross, who were once considered as the greatest swimmers, with amazing speed and lasting strength. Weismuller once set 5 world swimming records. Fourth, vegetarianism is good for losing weight and improving body shape. Relevant scholars believe that eating too much meat will increase the accumulation of lactic acid in the human body. When lactic acid increases, the blood will become acidic, and acidic substances will slow down the normal metabolism of the human body and cause obesity. The vegetable food in vegetarian diet can make the blood alkaline, but it can enliven the metabolism of the human body and decompose and burn the fat accumulated in the body to achieve the effect of natural weight loss. Fifth, vegetarianism is the most effective way to keep fit. There are no young stars in Hollywood, and there is always one in their maintenance secret recipe: they abstain from all meat for one to three days a week, and they try to eat as little meat as possible in their food every
day in order to purify their blood. Seeing their shiny skin is enough to prove that the benefits of vegetarianism are obvious. In addition, vegetarianism is fundamentally beneficial to ecological protection. In order to meet the needs of meat eaters, it not only consumes a lot of resources on the earth, but also causes serious pollution. According to experts' investigation, to get a pound of beef, it is necessary to consume 2 pounds of food crops to feed beef cattle. In order to grow crops to feed cattle, sheep, pigs, chickens, etc., a large number of chemical fertilizers and efficient pesticides are used. The final result is that the "health" of the land is destroyed and the productivity is declining year by year. However, in order to improve productivity as soon as possible, people have to use more chemical fertilizers. As a result of such a vicious circle, how can human beings be healthy? Therefore, medical experts and environmentalists have long warned people that personal eating habits and lifestyles are not only related to their physical and mental health, but also have a profound impact on the health of the earth. Therefore, the lines in the American film "The Plague of the Earth" can give more warnings to human beings: "We have no right to complain, but we have the responsibility to restore the world to normal order. What else do we have but to survive? "
John Robbins, the author of The New American Diet, spent nearly three years interviewing large farms and slaughterhouses, and came to the following conclusions: First, more than half of the water in the United States is used to raise animals for people to eat. It takes 5 gallons of water to produce a pound of meat, but only 25 gallons of water to produce a pound of cereal. Second, 26 million acres of forests in the United States have been developed into cultivated land to produce grain and raise livestock. That is, as long as one person becomes a vegetarian, an acre of forest can be preserved. Third, three-quarters of the topsoil in the United States is lost, of which 85% is caused by raising livestock. Therefore, on March 2, 1985, the United States launched the "No Meat Day" for the first time in 26 cities. Aris Hirsch, a wave-born environmentalist, said that the "No Meat Day" was first to solve the serious health problems caused by meat. Every year, 15, people in the United States suffered from coronary artery disease, cerebral thrombosis and cerebral thrombosis. Fourthly, 9% of wastewater pollution is caused by animal husbandry, which produces 2 pounds of excrement every day, 2 times more than the population of the United States, and at least half of it directly flows into water sources. Therefore, to maintain and establish a reasonable ecological environment, it is necessary to actively improve human eating structure and living habits, eat less meat, and eat more fresh and nutritious multi-fiber and low-fat fruits, vegetables, mushrooms and other foods and grains.
so how should a reasonable vegetarian diet be carried out? Experts at home and abroad who have been engaged in vegetarian research for a long time generally believe that vegetarian food is beneficial to human health. Generally speaking, the following principles should be followed: First, reasonable collocation and proper intake, such as balanced intake of cereals, beans, roots and leafy vegetables, will not lead to a shortage of protein and various substances needed by the human body. Second, we should adjust measures to local conditions, eat vegetarian food according to people and seasons, and supplement nutrients needed by organisms according to our own physical health. For example, people with poor gastrointestinal function can eat more purple broccoli. People with poor bones should eat more apples and spinach and drink more milk; People lacking in protein can eat more nutty foods such as peanuts and almonds. However, for people who mainly eat meat for a long time, they can adopt a diet habit of changing from less meat to more vegetables and gradually develop a vegetarian diet.
To sum up, diet is the main way to maintain human life activities, and it is also a kind of culture. Vegetarianism has become an unchangeable dietary trend and a new trend for human beings to pursue health today and even in the 21st century. According to statistics, there are 2% vegetarians in the United States. In London, England, about 3 million people have decided to give up meat, and the number is still increasing gradually. It is estimated that one-tenth of young women are vegetarians today. In the past three years, one-third of British people have reduced their meat, and more and more restaurants and schools have begun to serve vegetarian food. It is reported that Prince Charles, Princess Diana and the famous pop singer Michael Jackson are all meat-neutral. China's Taiwan Province, Hongkong, Southeast Asia and other countries have a strong vegetarian atmosphere in recent years. There are 1 million vegetarians in Taiwan Province with a population of only 2 million. It is by no means accidental that human beings are infatuated with vegetarianism, but through long-term life practice, personal observation, experience and comparison of a large number of life examples, they gradually understand the profound relationship between vegetarianism and life, and thus have a deep affection for vegetarianism.
Since ancient times, China's food culture is world-famous. The four major cuisines and the Manchu-Chinese banquet are mostly based on the taste. How to eat nutritionally and healthily? Today, we should seriously study, perhaps sometimes it is difficult to achieve the best of both worlds, different people have different opinions, so how should we decide to choose? Good health or delicious food? This paper only puts forward opinions from one angle. In order to better, healthily and freely maintain one's own healthy body and make the body and mind develop healthily in an all-round way, we should take the scientific concept of health preservation as the fundamental guarantee for health and longevity, and at the same time, we should also give priority to correct and reasonable vegetarian health preservation, adapt it to people according to time, place and place, and proceed from reality.
In recent years, with the increasing incidence of "rich diseases" such as hypertension, coronary heart disease, diabetes, hyperlipidemia and obesity caused by overnutrition, and the influence of the weight-loss craze for health and beauty, vegetarianism has gradually become a fashion.
The saying that vegetarianism can lead to a long and healthy life still has a good market among the people. Some people even pointed out that a certain monk lived for more than 1 years, so vegetarianism is good. Actually, this is just an example. As far as the current scientific research is concerned, there is not enough evidence to show that vegetarianism is necessarily related to longevity.
Long-term nutritional imbalance of vegetarian diet
The six nutrients to maintain people's health are protein, fat, sugar, vitamins, minerals and cellulose, each of which is very important to the body and indispensable. Taken together, these nutrients have three main functions: 1. Supply heat energy for human body. 2. Supply human tissues for growth, development or repair. 3. Help the human body adjust its functions.
When vegetarianism almost became a fashion, many experts suggested that vegetarianism would affect health. According to a survey of monks' life span, it is found that monks' life span is lower than that of ordinary people because of their long-term vegetarianism, low physical resistance and more anemia. Some people go on excessive diet or partial eclipse in order to meet the "standard" of modern bodybuilding, which has caused serious harm to health. Scientists have found that long-term abstinence from meat and animal products will make some nutrients needed by the human body not be replenished in time, which will damage some organs in the human body.
Affect sexual desire over time
Long-term vegetarianism affects people's sexual function as well as their whole health. American nutritionist Anna Marie Gerben pointed out that vegetarianism affects sexual desire. One of her surveys shows that vegetarians have a high proportion of apathy, premature ejaculation and even erectile dysfunction.
scientific research has found that animal fat can increase the secretion of sex hormones in the body, while vegetarian food does not contain any meat, which will reduce people's sexual desire. and
