Importance of a healthy diet
A major feature of modern life is busyness. People have a fast pace of life and are busy with work. In this case, it is easy for people to ignore healthy eating habits. For example, after getting up every morning, everyone is rushing to work and class, so many people choose breakfast as long as it is convenient and does not necessarily need enough nutrition. Some people don't even have breakfast until noon.

The habit of skipping breakfast is not only bad for your health, but also harmful to your health. Starting a busy day without breakfast will reduce the sugar in the blood and make people feel listless and have no strength to do anything. People who skip breakfast for a long time are also more likely to suffer from gastrointestinal diseases. If you are on an empty stomach for a long time, it may cause gastritis and gastric ulcer.

"The way to keep fit is not before meals". Using food nutrition to prevent and treat diseases can promote health and longevity. By adjusting diet, we can supplement organ function and promote physical health and disease rehabilitation. As the saying goes, "medicine is better than food." The so-called food supplement means that food can play a role that drugs can't. In China, dietary regulation has a long history as a means of keeping fit. For example, Sun Simiao, a famous doctor in the Tang Dynasty, made great contributions to food and health care. He believes that the elderly should first pay attention to diet in treating diseases, because "food can drive away evil spirits and press the five internal organs, which makes people feel relaxed and refreshed and tonify qi and blood. Although the medicine is strong, it is still an enemy, and the medicine is partial to help, making people filthy and vulnerable to foreign enemies. Therefore, if food can be used to alleviate the disease, it is easiest to reap the benefits of health care. "

Diet is the basic condition for human beings to maintain their lives. To make people live a healthy, happy, energetic and intelligent life, we should not only be satisfied with having a full stomach, but also consider reasonable distribution of diet to ensure that all kinds of nutrients needed by the human body are balanced and sufficient, and can be fully absorbed and utilized by the human body.

To balance nutrition, we must first develop good eating habits. Don't be hungry, don't overeat, don't be partial to food, and don't neglect. We should also pay attention to the hygiene of diet, and avoid certain things according to our physical condition, so as to prevent the occurrence of diseases and achieve the goal of healthy and long-lived diet.

The World Health Organization has put forward four cornerstones of health: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance. Therefore, a reasonable diet is an important part of health. But now, more and more scientific research results show that most diseases that endanger human health are caused by improper diet. Most people only pay attention to the taste and convenience of food in their daily diet, but not enough attention to nutrition, hygiene and health. It is particularly important to advocate a healthy diet if you want to have a healthy body.

With the development of society and the continuous improvement of people's living standards, people pay more and more attention to diet health care. Everyone knows that a healthy body comes from a healthy diet. In the past, people thought that only disease was the killer of health. In fact, the bad living habits based on diet and daily life are the biggest threat to health, which has a greater impact on health than diseases. High-fat diet, smoking and drinking, lack of rest, irregular schedule, etc. Will become a health hazard, which will directly lead to the decline of health status.

In modern life, all kinds of pollution have caused different degrees of damage to the human body. If we don't pay attention to diet and cooking methods, this improper diet will increase the risk of illness. Therefore, a scientific diet, combined with good eating habits, can not only prevent cell canceration, but also accelerate the discharge of poisons in the body and maintain good health.

Studies have shown that diet is closely related to cancer. According to statistics, 1/3 cancer cases are related to diet. Possible carcinogenic factors include: carcinogenic foods, carcinogens and cooking methods. It is believed that animal fat may increase the risk of prostate cancer and rectal cancer, and a diet rich in animal fat is also related to the occurrence of female breast cancer. According to the survey, people with the most fat in their diet have the highest proportion of breast cancer and prostate cancer. Foods containing nitrosamines, mildew and high salt all contain carcinogens. In some areas, the content of nitrosamines in drinking water and food is high, and the incidence of esophageal cancer is also high. Food mildew can also cause cancer, such as moldy peanuts and corn containing aflatoxin, which can lead to liver cancer. Eating high-salt and pickled foods often leads to esophageal cancer and gastric cancer. Improper cooking methods, such as frequent direct barbecue of meat with fire, will produce carcinogens. Experts believe that it is better to stew, steam, cook, bake in the oven and use microwave oven to cook meat, rather than barbecue directly with charcoal fire.

So the diet should be scientific. Studies have shown that a good diet structure and good eating habits play a very important role in preventing and treating cancer. In daily life, we should first diversify our diet, eat less animal fat and foods high in sugar and salt, eat more fruits and vegetables, drink milk or soybean milk every day, and appropriately increase fish, eggs and lean meat to make all kinds of nutrition as complete and balanced as possible. At the same time, we should avoid moldy food and eat less smoked, grilled and fried food. It's best not to drink hard liquor. Those who have drinking habits can drink low-alcohol or wine in limited quantities. As long as we pay attention to a reasonable diet, we will definitely reduce the incidence of cancer.

There is no doubt that a scientific and reasonable diet can delay aging and make people look healthy and young. Long-term research by nutritionists shows that human aging and premature death are closely related to long-term satiety, overeating, unreasonable diet structure and unhealthy lifestyle.

In Little Rock, Arkansas, USA, there is the largest animal experimental base in the world. A novel experiment was conducted here: reducing the diet of mice by 70% can prolong their life span by 50%. After transferring this experiment to the study of human life, it is found that most diseases related to aging can be reduced or delayed by properly controlling calorie intake. Moreover, the research results of related laboratories prove that eating less may delay human aging, while eating more will shorten people's life span.

A considerable number of people in our country have transitioned from a subsistence life to a well-off life. A well-fed life can be full in diet, and a well-off life can go further in diet and eat well. Because life is rich and the quality of food has improved, the daily life of some families is: big fish and big meat, polished rice and fine noodles, cakes and drinks, and many people also smoke and drink, and often overeat. This way of life is a catalyst for accelerating human aging and an important cause of "disease of modern civilization".

In its annual report 1997, the World Health Organization pointed out that bad eating habits and lifestyles are the chief culprits of many chronic human diseases, which kill tens of millions of people all over the world every year. According to reports, more than 24 million people worldwide die of diseases such as cancer and heart disease every year. The westernization of life has made more and more people in third world countries develop bad habits peculiar to rich societies, such as smoking, drinking and eating foods with high fat and sugar. Dr. Kingsley Ji, representative of the Beijing Office of the World Health Organization, said: Some diseases that were traditionally thought to be confined to developed countries have now become "routine" in China, such as cancer, cerebrovascular disease, stroke and heart disease with extremely high mortality. In addition, the number of diabetic patients in China is also rising. It is estimated that there are more than150,000 diabetic patients in China, which is three times higher than that of 10 years ago. For this reason, the World Health Organization appeals to and persuades people to reduce the intake of high-fat, high-sugar and high-salt foods, not to smoke, not to drink too much, not to overeat, and to exercise more to protect their health and prolong their lives.
