So the doctor asked him to recall his usual eating habits, and it happened. It turns out that Li Shu usually has a heavy taste when eating, and usually puts a lot of salt when cooking. Doctors suspect that eating high-salt food for a long time may be an important reason for Li Shu's hypertension.
Eating habits are related to human health. Modern medical research shows that people's health and longevity are affected by many factors, and diet is one of the important factors.
So what is the relationship between diet and healthy life? How does diet affect health? Next, I will give you a detailed introduction. I believe you will have a deeper understanding after reading this article.
Recently, the University of Sydney published a new study, in which researchers investigated the relationship between nutrition supply in different countries and the risk of death at different ages. The researchers said: "In the case of relatively high supply of fat and protein, the risk of death in early life can be minimized. Moreover, reducing the energy supply in fat and replacing it with carbohydrates can reduce the mortality rate. On the other hand, this study also confirmed that there is a certain relationship between nutrition obtained from diet and human life expectancy.
In addition, the "life triangle" theory put forward by Japanese scholar Ichiro Nakagawa also explains the relationship between diet and healthy life. He compared human life span to the size of a triangle area. The larger the area, the longer the life. The smaller the area, the shorter the life. The base of an isosceles triangle represents genetic factors, and the two waists represent mental health and eating habits respectively.
Even if a person has no genetic advantage, that is, the base of the triangle is not long enough, as long as he pays attention to the balanced diet and nutrition, strengthens physical exercise and consciously increases the extension of the two waists of the triangle, then the area of the triangle, that is, the life span, can still be increased. A balanced diet is the basis of people's health and longevity. Appetite and diet nutrition will affect people's health and longevity. Eating too much and having too much nutrition may also lead to diseases, thus shortening life expectancy.
As we all know, Japan is called the country of longevity. In the investigation, Dr. Baboia Lola found that the incidence of cardiovascular diseases in Japan is low, and the secret of its longevity lies in a reasonable diet. It is reported that in recent years, China people's experience of longevity has been summed up, and Japanese people have made great efforts to reform the diet structure, surpassing the advantages of Chinese and western diets, and advocated designing and planning new dietary viewpoints and measures on the basis of plant and animal foods.
The survey found that in these longevity towns, people's eating habits and nutritional structure are closely related to the length of life. In addition, the diet structure of centenarians in Changshou area of Chinese mainland is mostly low in calories, fat, animal protein and vegetables. The quality of dietary nutrition directly affects people's health, disease resistance and longevity.
Therefore, we should pay more attention to our usual eating habits, cultivate healthy and good eating habits, and stay away from the wrong eating habits that are harmful to our health. The doctor will introduce you to several bad eating habits, so you must pay more attention.
The Lancet published a large-scale study on global diet, investigating the dietary burden and related diseases in 195 countries and regions. Among the 15 dietary factors ranging from 190 to 20 17, four dietary problems are particularly prominent in China. Let's have a look.
Excessive intake of pickled food.
Nowadays, many people like to eat pickled food, such as pickles and bacon. But it contains a lot of nitrate, which will be converted into nitrite in the stomach. Nitrate will react with amines in food to produce ammonium nitrite, which is carcinogenic to some extent, thus increasing the chances of suffering from gastric cancer, intestinal cancer and laryngeal cancer. Often eating some processed salt products, such as bacon, can cause intestinal cancer such as rectal cancer. So try to eat fresh vegetables and meat and control the intake of pickled food.
Eat too little whole wheat.
Whole grain refers to the grain that retains endosperm, germ and original nutrients without fine processing such as grinding and crushing. The staple food we usually eat is mostly flour and rice, such as rice and white flour. Fine processing will make the grain lose a lot of nutrition, because after fine processing, almost only starch is left, and dietary fiber is relatively lacking, which leads to too fast digestion, which is not conducive to controlling blood sugar and weight.
Compared with flour and rice, whole grains contain more vitamins, dietary fiber and minerals. Eating more whole grains can reduce the incidence of chronic diseases such as type 2 diabetes, colorectal cancer and cardiovascular disease. So dietary fiber can be supplemented by increasing the consumption of whole grains.
Eat too salty
The Dietary Guidelines for China Residents suggest that normal people should consume less than 6 grams of salt every day. However, according to the investigation in China in recent years, the average daily salt intake of China people is around10g, which far exceeds the normal consumption. Eating too much salt is very harmful to health. The main source of sodium in our daily diet is salt. A large number of studies have found that excessive intake of sodium will increase the risk of hypertension, gastric cancer, stroke and other diseases.
Eat too sweetly
In daily life, a small or moderate amount of sweets is basically harmless to the human body. However, if you eat a lot of sweets for a long time, it will increase the burden of islet secretion during digestion and increase the risk of diabetes. In addition, sweets contain a lot of sugar. After long-term consumption, the sugar in the body will accumulate and turn into fat, leading to weight gain. Moreover, sugar is an acidic substance, which will make the alkaline environment in the body neutral or weakly alkaline after a large amount of intake, leading to the increase of free radicals in the body, thus accelerating aging.
Since the above eating habits are harmful to people's healthy life, what should people do in their daily diet? The following doctors will introduce some good eating habits for your reference.
What should a reasonable dietary structure look like? It is a food pyramid, which was put forward by American nutritionists in 198 1. Its basal layer is grains, potatoes and beans, so you should eat more. The second layer is vegetables and fruits, which should be supplemented in daily life. The consumption of meat, eggs, milk, poultry, fish and tofu on the third floor should be moderate, the spire is energy food, and fat and sugar food should be eaten less. Keeping the balance of the food pyramid is an important way to keep healthy.
So how to maintain a healthy diet?
First of all, the diet should be balanced. In fact, a person's daily diet needs four categories: staple food, protein complementary food, vitamins and minerals, and energy food. Maintaining balanced nutrition can promote the normal growth and physiological activities of the human body to the greatest extent, and can reduce the risk of many diseases, including hypertension and cardiovascular diseases. Try not to be picky about food and eat more vegetables when eating. Picky food will lead to unbalanced nutrition and affect the growth and development of the body.
In addition, don't eat dessert after eating greasy things to prevent human adipose tissue from absorbing excess glucose and making people fat. You can have some coffee or tea after eating greasy things. Tea and coffee are rich in caffeine, which can stimulate plant nerve activity and promote fat metabolism.
Dinner should be moderate, so that you can have an appetite for breakfast the next day. Moreover, it is not appropriate to eat cold drinks after meals, and the human metabolism is not active at night. If you eat cold drinks after 7: 00 pm, due to the slow metabolism of water, it will accumulate in the body, lowering the body temperature and leading to poor sleep quality. And don't eat before going to bed, eat before going to bed, the stomach can't get enough rest, which may easily lead to stomach trouble and affect sleep, but it is ok to drink a cup of hot milk before going to bed.
You can have some tea after dinner. The main component of tea is tannic acid, which has the function of sterilization and disinfection. It can clean food residues in the mouth, prevent oral bacteria from breeding and cause oral diseases. In addition, proper exercise should be carried out after meals to promote digestion. The food began to digest about half an hour after the meal. At this time, you can do some low-intensity exercise such as walking and tai chi. An hour after a meal, food begins to enter the intestine, and the burden on the stomach will be reduced. At this time, you can do some slightly strenuous exercise, such as jogging.
You can eat some fruit before and after meals, which helps intestinal digestion and enhances immunity. Fruit is rich in dietary fiber and vitamins, and also contains a variety of natural plant compounds, which have many physiological functions such as enhancing immunity, delaying aging, and helping to prevent chronic diseases such as cardiovascular and cerebrovascular diseases. As early as 2002, the World Health Report issued by the World Health Organization listed too little fruit intake as one of the top ten high-risk factors for death. Therefore, the intake of fruit should be increased in daily life to maintain a balanced nutrition.
Diet has a great relationship with healthy life span, and healthy eating habits can effectively prolong life span to some extent.
Therefore, we should strive to put an end to unhealthy eating habits in our daily life. Avoid eating too much sweet and salty food, and eat a balanced diet of cereals and preserved foods. Avoid drinking cold drinks after meals. You can exercise after meals to promote digestion and make yourself healthier.
In a word, diet has a great influence on human body. Everyone should pay attention to eating habits, and don't suffer from incurable diseases in the future because of gluttony. Develop correct eating habits, from now on!
