The child's body develops rapidly and needs to absorb a lot of nutrients, but the gastrointestinal tract is not mature enough and the digestive ability is not strong. For example, the capacity of the stomach is only about 250 ml, and their teeth are growing and their chewing ability is limited.

The daily supply of milk and corresponding dairy products is not less than 350 ml, and attention should also be paid to the supply of eggs and egg products, semi-fat poultry meat, liver, processed beans and chopped vegetables.

The weight can be increased by 4-5 kg every year, and the individual can reach 8- 10 kg. At this time, not only the growth is fast, but also the secondary sexual characteristics gradually appear. In addition, the amount of activity is large, the learning burden is heavy, and the demand for energy and nutrients exceeds that of adults.
Grain is the main source of energy and protein in China's diet. Teenagers need a lot of energy, about 400-500 grams a day, which varies according to the amount of activity. Insufficient intake of protein will affect the growth and development of teenagers, and half of the daily intake of protein by teenagers should be high-quality protein. Therefore, the diet should contain enough animal and soybean foods, and calcium is an important component in building bones.

With the increase of age, the physiological functions of various organs of the human body will decline to varying degrees, especially the digestive and metabolic functions. Xiaojie affects the nutritional status of human body, such as tooth loss, decreased secretion of digestive juice and slow gastrointestinal peristalsis, which makes human body absorb and utilize nutrition.
Therefore, the elderly must get enough nutrients from their diet, especially micronutrients. The gastrointestinal function of the elderly is declining, so we should choose digestible food to facilitate absorption and benefit Sichuan. But the food should not be too delicate, but should pay attention to the thickness. Dietary fiber can increase intestinal peristalsis, prevent senile constipation, improve intestinal flora, and make food easy to digest and absorb, especially soluble fiber can improve blood sugar and blood lipid metabolism (the diet contained in oats and corn)
Eat more fiber than rice and wheat). The elderly have decreased basal metabolism and are prone to overweight or obesity since childhood. Obesity will increase the risk of chronic non-communicable diseases, so the elderly should actively participate in appropriate physical activities or sports, such as walking and Tai Ji Chuan, so as to improve their various physiological functions. However, due to the decrease of vascular elasticity, the increase of blood flow resistance and the decline of cardiovascular and cerebrovascular functions in the elderly, it is not appropriate to exercise excessively, otherwise it will damage the function beyond the endurance of cardiovascular and cerebrovascular diseases and increase the risk of such diseases.
Therefore, the elderly should pay special attention to reasonably adjusting the balance between food intake and physical activity momentum to keep their weight within a suitable range.
