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

1. 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.

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.
