If you don't pay attention to your diet, there will be four situations.
① Insufficient diet can not meet the needs of the body, which can lead to malnutrition;
② Excessive food will lead to overnutrition and obesity;
③ Unreasonable diet can lead to partial malnutrition;
4 unclean and improper diet can lead to pathogenic factors.
Although eating is human instinct, not everyone drinks reasonably and eats scientifically. Therefore, in order to live a long and healthy life, we must seriously study the methods and knowledge of diet.
(1) Reasonable diet: With the continuous improvement of living standards, people are increasingly concerned about what kind of food to eat and how to eat it. Scientific nutrition is good for health. Scientific nutrition is an adequate and balanced diet, which ensures all the nutrients needed by the human body, and the nutrition ratio is appropriate and beneficial to health. For people, following the principle of reasonable dietary nutrition is the basis of scientific nutrition.
(2) Rational allocation: pay attention to the diversification of staple foods and mix coarse grains with flour and rice. Non-staple food should pay attention to the mutual collocation of meat and vegetables, and try to avoid the repeated collocation of similar foods. Nutritionists recommend the following five types of food: ① cereals; ② Meat and eggs; ③ Dairy products; ④ beans and bean products; 5 vegetables and fruits; (5) salt, oil and other condiments and drinks.
(3) The principle of reasonable diet: Because everyone's environment and physical condition are different, the principle of reasonable diet is also different. The purpose of a reasonable diet is to keep healthy, reduce diseases and prolong life.
① Diversity. Because different foods contain different kinds, different qualities and different amounts of nutrients, we should try to have six basic foods in our daily diet. This is because no food is perfect. The disadvantage of cereal is the poor quality of protein, which contains no vitamins A, P, C and B 12. There are few protein, fat and carbohydrate in vegetables and fruits, but there are many kinds of vitamins and minerals. Dairy products with high nutritional value also lack inorganic salts such as iron, dietary fiber and vitamin C. Therefore, it is impossible for any food to contain all the nutrients needed by the human body, nor can it maintain the health and life of the human body alone. Mixing these different kinds of foods together can make up for the shortcomings of various foods and reduce the unfavorable factors of food (for example, phytic acid in food hinders the absorption of minerals, and dietary fiber can be reduced accordingly).
2 Eat properly: eat less, too much is harmful. For example, too much energy and fat will increase the incidence of many diseases and make people fat. Therefore, the intake should be determined according to years of practical experience.
③ Control the intake of sugar, fat, salt and dietary fiber: Excessive intake of sugar and fat will lead to obesity and increase the incidence of some diseases; Eating too much salt can lead to high blood pressure.
④ Cooking methods should be appropriate: to prevent the nutrients from being destroyed.
⑤ Adhere to a good diet system: Three meals a day is a good diet system, and pay attention to the nutrition of each meal.
6. Moderate drinking: Alcohol can be drunk, but not excessive. Excessive drinking will do great harm to your health.
All landowners food should be non-toxic, harmless and clean.
8 Insist on proper exercise: Proper exercise can increase the absorption of nutrients and help the body's metabolism.
(4) Scientifically arrange three meals a day: The ancients said: "Breakfast is better, lunch is full, and dinner is less" is the motto summarized according to this principle. Eating a good breakfast means eating food with high nutritional value, less but better. It embodies the principle of small quantity, high quality, equal emphasis on lean and lean, and staple food. It is best to match 1-2 kinds of high-protein foods, such as eggs, milk, soybean milk, peanuts and soybeans. In real life, many people are careless about breakfast or even skip breakfast, which seriously violates the law of human physiological needs.
Having a full lunch is to ensure the quality of food. Due to the large amount of activities in the morning and evening, there are many staple foods and diversified non-staple foods. There should be meat, eggs, beans and vegetables on the table. It's best to eat a bowl of vegetable soup with meat and vegetables in it. You can eat fruit half an hour after lunch.
Eat less at dinner, that is to say, eat less food, because there is less activity at night (excluding night shift workers) and the body needs less nutrition. On the other hand, overnutrition will lead to obesity and even induce diseases. The general situation now is that people's lives are tense and their work is busy. They often have a poor breakfast, eat rough at noon, have a big meal when they go home for leisure at night, and then fall asleep. In the long run, it is easy to induce various diseases. Therefore, we must make up our minds to overcome this bad habit.
