The so-called "comprehensive" means that the intake of various nutrients should be comprehensive, which is the basis of a balanced diet. There are seven categories and more than 40 subcategories of nutrients needed by the human body. One or several foods alone cannot provide all the nutrients needed by the human body. For example, eggs are a kind of nutritious food, which is rich in high-quality protein, lecithin, cholesterol and B vitamins, but contains little vitamin C and dietary fiber. If you eat scrambled eggs with tomatoes, you can supplement these deficiencies and achieve comprehensive nutrition. This is a simple example of a balanced diet. Therefore, people are required to eat as wide a diet as possible, eat as many kinds of food as possible every day, pay attention to the collocation of meat and vegetables, the collocation of thickness, the collocation of main and auxiliary, and give consideration to flowers, fruits, roots and stems, so as to be conducive to comprehensive nutrition.
The so-called "balance" means the relative balance between the intake of various nutrients and the needs of the human body. Men need a lot of protein and calcium to keep their muscles strong, while athletes need a lot of high-energy food. -Some patients can relieve their illness and promote their recovery by supplementing people with a large amount of vitamin C. Men's needs for diet and nutrition are different at different times of the day, different seasons of the year, different life and work rhythms and adaptation needs to different environments. For men, too little nutrition intake can not meet the needs, and malnutrition diseases can occur; Excessive intake is not only a waste, but also a burden on the body, leading to overnutrition diseases. There is weighing scale at home, so it is very meaningful to observe your weight changes frequently as a reference for adjusting your intake.
The so-called "appropriate" means that the proportion of various nutrients should be appropriate, and a reasonable dietary structure should be formulated in a comprehensive and balanced manner. There is a certain proportional relationship between the composition of human elements and the demand for various nutrients under different conditions. Only the combination that meets the needs of the human body is conducive to better absorption and utilization, and too much or too little will affect human health. For example, the diet of the elderly is suitable for low salt, low sugar, low fat, high protein, high cellulose and high vitamins. In addition, it is necessary to take appropriate regulatory health food.
Only by ensuring a balanced diet and reasonable nutrition can we better promote our health.
