Very long. Vegetarianism has been popular in western developed countries for many years. Long-term research in the scientific and medical fields has confirmed that vegetarianism 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 always been thought that carnivores are fierce and strong, so it is beneficial to infer that people eat more meat. In fact, this is a big misunderstanding. The ancients said: if you want to live forever, your intestines should be clear. Experts point out that the intestines of animals are very short, and the absorption and excretion cycle after eating meat is also very short. However, the human intestine is much longer than that of animals, and the waste after eating meat cannot be discharged in a short time, which may pollute the internal organs and cause diseases. Eating more meat will cause blood acidity. According to clinical observation, 70% of human diseases occur in acidic constitution, such as hypertension, heart disease and stroke. After studying the food composition of seven countries, scientists found that the countries with the highest meat consumption had the highest coronary heart disease and mortality, while vegetarians had 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 paste beam for a long time are enough to have big boils on their bodies. It's as easy as taking an empty container to accept something. Experts generally believe that vegetarian food is nutritious, delicious, clean and hygienic, which helps to reduce the blood lipid content of human body and avoid pathological changes caused by improper meat cooking. Vegetarians live longer and have fewer diseases, which is the inevitable result. A survey report shows that 100 vegetarians and 100 meat eaters in Shanghai and Suzhou were examined by three departments of Shanghai Eighth Five-Year Hospital in September 1985. As a result, the blood viscosity of meat eaters is much higher than that of vegetarians. 100 vegetarians, only 18 people suffer from cardiovascular diseases, but there are 67 vegetarians and 57 vegetarians are disease-free. As we all know, high blood viscosity is the cause of coronary heart disease and various chronic diseases.
Therefore, vegetarianism 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 is the lowest. Harvard Medical School once did an experiment about vegetarianism. If vegetarians eat half a pound of beef every day, their cholesterol will increase by 19% and their pulse will accelerate. When the experiment ends and they return to vegetarian diet, their cholesterol will return to its original state within 10 to 14 days. After a follow-up survey of 1 100 subjects, the British medical community found that heart disease can be effectively prevented if cholesterol and blood pressure are properly controlled, and the incidence of heart disease in vegetarians is much lower than that in 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 can 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, and vegetables and fruits contain inexhaustible anti-cancer factors. Scientists have found that the number of people suffering from cancer in Shanghai is four to seven times higher than that in China, which is probably directly related to the high-fat diet of Americans. Fourth, being a vegetarian is not easy to suffer from gallstones. Medical experts from Oxford University in England conducted experiments on 700 vegetarian women, and the conclusions are as follows: their probability of suffering from gallstones is only half that of the general population; Fifth, vegetarians are not prone to diabetes. Relevant research reports point out that meat or fat can interfere with insulin metabolism, so vegetarians are not easy to get diabetes. A survey of 25,000 experimenters for 2 1 year 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.
For the benefits of light diet, Sun Yat-sen, a pioneer of modern revolution, has played a very good role in the article "China people should observe China's diet law". He said: "China has not only rich food inventions, but also beautiful cooking methods, which are beyond the reach of all countries, while China people's eating habits coincide with scientific hygiene, which is beyond the reach of ordinary people in all countries. People in China often drink green tea and eat light rice with vegetables and tofu. These foods are tested by today's hygienists as the most beneficial to health. Therefore, people in the hinterland of China eat less wine and meat and often live long. " 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, which is the meat in real plants. This thing has the power of meat, but it is not poisonous. Therefore, China has become accustomed to being a vegetarian all over the country, instead of 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: "Europeans and Americans drink turbid wine, and people who eat it smell fishy and learn from each other." Therefore, although science was advocated in the past, it was later strictly prohibited by law. For example, modern countries such as Russia and the United States strictly banned alcohol, which could not be turned around 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 achieve nature. "
The benefits of vegetarianism are shown in the following aspects: First, vegetarianism helps people feel refreshed and calm. Especially for people who practice martial arts and qigong, they can enter silence faster and better, so as to achieve the purpose of benefiting body and mind and prolonging life. Second, vegetarianism can enhance patients' resilience as soon as possible. Relevant data show that vegetables are not only rich in vitamins, but also contain essential minerals, which have the functions of disease prevention and medical care.
Sick children can obviously improve their health if they eat more vegetables, beans, fruits, kelp and milk. Third, vegetarians have good physique, agility and strong endurance. Vegetarians have pure blood, low blood viscosity, and blood can circulate freely in the viscera, so that all parts of the viscera will not get sick due to blockage, the viscera will become strong, and other organ systems will naturally be healthy. Therefore, vegetarians are healthy, not prone to sudden pathological changes, easy to be emotionally stable and well-proportioned. No meat eater consumes too much fat, and protein is stored in the body, which makes them look sluggish and falter. 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. Wes Muller has set 50 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, blood will become acidic, and acidic substances will slow down the normal metabolism of the human body and cause obesity. Plant food in vegetarian diet can make blood alkaline, but it can invigorate the metabolism of human body, decompose and burn the accumulated fat in the body, and achieve the effect of natural weight loss. Fifth, vegetarianism is the most effective way to keep fit. Hollywood is not a girl star, and there is always one in their maintenance secret recipe: fast all meat for one to three days a week and purify the blood.
Japanese food eats as little meat as possible. Seeing their bright 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 takes 20 pounds of food crops to feed beef cattle. In order to grow crops to feed cattle, sheep, pigs, chickens, etc. , a large number of 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 increase 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 far-reaching impact on the health of the earth. Therefore, the lines in the American film "The Plague of the Earth" can better warn mankind: "We have no right to complain, but we have the responsibility to restore the normal order of the world. Besides survival, what else do we have? "
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 human consumption. It takes 500 gallons of water to produce a pound of meat, but only 25 gallons to produce a pound of grain. Second, 260 million acres of forests in the United States have been developed into cultivated land to produce food and raise livestock. That is, as long as one person becomes a vegetarian, one 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. Thus,1On March 20th, 985, the United States launched the "Meat Free Day" for the first time in 26 cities. Aris Hirsch, the wave environmentalist in charge of this activity, said that the "Meat-free Day" was first to solve the serious health problems caused by meat, and there were 65,438 in the United States every year. Fourth, 90% of wastewater pollution is caused by animal husbandry, which produces 200 pounds of feces every day, 20 times more than the population of the United States, and at least half of it flows directly into the water source. Therefore, to maintain and establish a reasonable ecological environment, it is necessary to actively improve human diet structure and living habits and eat less.
Meat, eat more fresh and nutritious multi-fiber and low-fat fruits, vegetables, mushrooms, shavings 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 moderate intake, such as balanced intake of cereals, beans, roots and leafy vegetables, will not lead to the shortage of protein and various substances needed by the human body. Second, we should adjust measures to local conditions, because people eat vegetarian food according to their own physical health and supplement the nutrients needed by the body. 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 who lack protein can eat more nuts such as peanuts and almonds. However, for people who mainly eat meat for a long time, they can adopt a diet habit from eating less meat to eating more vegetables, and gradually develop vegetarian diet.
To sum up, diet is the main way to maintain human life activities, and it is also a culture. Vegetarianism has become an unchangeable dietary trend and a new trend of human pursuit of health at present and even in 2 1 century. According to statistics, there are 20% vegetarians in America. In London, England, about 3 million people decided to give up eating meat, and the number is gradually increasing. It is estimated that one in ten young women today is a vegetarian. In the past three years, one-third of the British people have reduced their meat, and more and more restaurants and schools have started to serve vegetarian food. It is reported that Prince Charles, Princess Diana and the famous pop singer Michael Jackson all don't eat meat. China's Taiwan Province Province, Hongkong, Southeast Asia and other countries have become very vegetarian in recent years. There are only 20 million people in Taiwan Province province, but there are100000 vegetarians. It is no accident that human beings are obsessed 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 feeling for vegetarianism.
Since ancient times, China's food culture has been world-famous. Most of the four major cuisines and Manchu-Chinese banquets are mainly about taste. How to eat nutrition is healthier? Today, we should seriously study, maybe sometimes it is difficult to achieve the best of both worlds, and different people have different opinions, so how should we decide to choose? Good health or good food? This paper only puts forward the views from one angle. In order to maintain our healthy body better, healthily and freely, and make our body and mind develop in an all-round and healthy way, we should take the scientific concept of health preservation as the fundamental guarantee of health and longevity, and at the same time, we should put the correct and reasonable vegetarian health preservation in the first place, and set out from reality.
