Why eat more vegetarian food and less meat? (From the aspects of body, ecological environment and so on)

Eating more vegetarian food and less meat will help reduce the risk of death.

For human health, plant protein is superior to animal protein, and chicken and fish are superior to red meat, milk and eggs in animal protein. From the point of view of diet, most nutrients come from food, and there are many kinds of nutrients in each food. Therefore, researchers believe that it is equally important to study the impact of food sources on health in protein, and therefore analyzed the data of two large-scale follow-up studies in the United States.

In these two studies, researchers collected information on diet, lifestyle, health status and disease diagnosis of more than 654.38+million nurses and health professionals through questionnaires, and collected death information of these subjects by using family reports and national death database.

In the latest research, Song Mingyang and others used statistical models to analyze the relationship between animal protein and plant protein intake and mortality. The results show that the food sources in protein have an important impact on health. Intake of high animal protein, especially animal protein from red meat, is positively correlated with death risk, while intake of high plant protein is negatively correlated with death risk.

2. Being vegetarian and eating less meat can protect the environment.

A report warns that we need to do more to protect the environment.

The number of mammals, birds, reptiles, amphibians and fish has decreased sharply. In the past forty years, the number of these animals has decreased by 60%.

"Nowadays, destroying nature is regarded as the price of development, but we can't go on like this," said Tony Juniper, executive director of the World Wildlife Fund.

During the period from 1970 to 20 14, the number of exotic species such as elephants, rhinoceroses and polar bears decreased greatly, and so did the puffins and hedgehogs familiar to the British.

The number of animals living in tropical areas and freshwater habitats is particularly decreasing. Only a quarter of the earth's surface can be protected from human activities, and by 2050, this area will be reduced by one tenth.

Habitat loss, poaching, pollution and climate change will all lead to the crisis of animal population decline, and experts believe that traditional strategies can no longer solve this crisis.

Overfishing, deforestation, the use of pesticides and other human activities are the key to the decline of many species.

Mr Juniper pointed out that individual actions can play a role in protecting animals. He said that changing the attitude towards food is an important strategy.

"The biggest thing most of us can do is to eat less meat," he said.

Extended data:

Benefits of becoming a vegetarian:

1, lose weight A five-year follow-up survey published in Journal of American Nutrition and Dietetic Association 20 13 shows that the average height and body mass index of people who don't eat meat are lower than those who eat meat, and the obesity rate of vegetarians is significantly lower than that of omnivores (9.4% vs. 33.3%). In addition, people who eat less meat are slimmer even if they consume the same amount of calories.

2, it is not easy to get cardiovascular disease. Eating too much meat and dairy products will increase the cholesterol content in the blood. Too high cholesterol content in the blood will increase people's risk of heart disease.

3, blood pressure is reduced. A study published in the Journal of Health Nutrition shows that the prevalence of hypertension in vegetarians is lower than that in meat eaters. This is because the former has a lighter average weight and eats a lot of fruits and vegetables.

4. Reduce the risk of diabetes. A study conducted by the American Diabetes Association shows that eating less meat will reduce people's risk of metabolic syndrome, which is a group of risk factors related to type 2 diabetes, stroke and heart disease.

5. Improve digestive function. Eating more vegetables and beans means increasing the intake of dietary fiber, which can improve the overall digestive function and reduce constipation.

The medical profession has done such a study, comparing the intestines of carnivores with those of people. Take the tiger as an example. Its intestines look short and straight without many wrinkles. We know that meat is perishable, so God gave the tiger a short intestine, so that the digestive residue of meat would not stay in the intestine for too long. People's intestines are always about 30 feet long, and the large intestine alone is five feet long, which is nearly three times that of tigers, so people should not eat meat; Because meat is perishable, it is more prone to decay and fermentation at the temperature of the intestines. We can imagine that the feces of herbivores do not smell like carnivores. It is conceivable that carrion will produce many pathogenic bacteria and toxins in the human intestine.

Another point is that people's molars are developed and suitable for grinding food, that is, eating whole grains and beans; Carnivores, with sharp front teeth and serrated teeth, are obviously used to grab life and crush the body ... Knowing this, people may understand why human beings are riddled with diseases, because people eat things that should not be eaten against the will of nature.

People often worry that vegetarian food is not nutritious enough. For this kind of worry, the most common response of vegetarians is to laugh without answering. They may be happy to compete with meat eaters for health. There is no doubt that vegetarians are healthier from all angles: their bodies are lighter, their reactions are more agile, their brains are richer, they are easier to fall asleep, and they need less sleep time and are more cheerful, so they are less depressed, less cold, less prone to calcium deficiency once they get better, and even better, they are less prone to cancer, hypertension, diabetes and Alzheimer's disease. An important cause of Alzheimer's disease is vascular distortion caused by fat. This year, a set of national data shows that the proportion in the north is higher than that in the south, and there are more women than men. The most dangerous people are the elderly women in the north. They happen to be frequent customers of fat meat stuffing. ...

Theoretically, vegetarian food can get better nutrition than meat. First of all, we should break the stereotype that meat is higher than vegetarian protein. In fact, the protein content of many vegetarians is higher than that of meat: for example, the protein content in nuts and melon seeds is 30%, and the grain content is about 10%. The protein content in beans is higher, nearly 40%, which is twice that of meat. The protein content in bean skin is as high as 50%, while the protein in soybeans is completely protein, which is more easily absorbed by the human body.

People joke that Cantonese people are not as strong as a northern man who eats steamed buns. People often use meat as a tonic. In fact, meat is not only less than beans in protein, but also the most deficient in vitamins and minerals in various foods.

Pea, wheat and oats contain twice as much iron as beef, and almost every plant contains more iron than meat. The calcium content of meat is not as much as that of vegetarian food: per100g of food, the calcium content of chicken is 5 (mg), beef is 8, pork is 12, fish is 30, pea is 7 1, mushroom is 125, auricularia is 207 and laver is 850.

Even the fat that meat is good at is always covered by vegetarianism. For example, the oil content of walnuts is as high as 66.9%; Peanut accounts for 48.7%, sesame 48.23%, soybean 20.20%, fatty acid 13 and animal fat 6, but all kinds of plant fats exist. Animal fat is saturated fat with high cholesterol content, which is easy to cause arteriosclerosis, hypertension and heart disease, and is beneficial to the proliferation of cancer cells. Vegetable fat is unsaturated fat, which can promote bile acid excretion, lower cholesterol and avoid heart disease and various cardiovascular diseases.

A vegetarian is not short of nutrition, and a long-lived vegetarian is the best proof.

There is an American medical organization that makes a comparative study of vegetarianism. Meatballs are extremely easy to find, but it is not easy to find a vegetarian. So they went to temples in China, remote temples in Sichuan and Hunan, and it didn't matter if they asked, which startled them. What are the ages of these old monks and the control group? The average age is 80. Vegetarian diet makes the body strong.
