Thermal energy is the heat source of life activities. Without heat energy, the blood sugar in the human body will drop, which will affect the efficiency of work and study. But too much heat energy storage will make people fat and cause many diseases.
Protein is one of the most needed nutrients for human body. All organs and cells of the human body are made of protein, and the protein of the human body is updated by half every 80 days on average. Therefore, protein's intake is not only the needs of children and adolescents' physical growth, but also the needs of adults.
A balanced diet must first meet the human body's demand for calories. The percentage of three thermogenic nutrients in total calories should be: protein 10% ~ 15%, fat 20% ~ 30%, carbohydrate 55% ~ 65%.
A balanced diet also includes intake of various vitamins and minerals. Only when the nutritional structure is reasonable can the body be healthy. In order to carry out nutritional catering, we must first understand the nutritional components and contents of various foods, and then choose foods to match and cook reasonably according to the human body's needs for heat energy, protein, minerals and vitamins. Secondly, the distribution of three meals a day is reasonable according to the ratio of 3: 4: 3, that is, breakfast accounts for 30%, lunch accounts for 40% and dinner accounts for 30%.
