Children are in a period of rapid growth and development, and the nutrition they need should be comprehensive. Protein, fat, carbohydrates, vitamins, minerals and other nutrients exist in whole grains, chicken, fish, eggs, fruits and vegetables. Long-term picky eaters will inevitably lead to the lack of certain nutrients and make people sick. If you get into the habit of eating whatever you want from an early age, you can make the nutritional components of various foods complement each other, learn from each other's strong points and play a higher nutritional value. This is what nutrition calls "complementary role". If meat and vegetables are eaten together, the absorption rate of iron and vitamin C can be improved. Long-term picky eaters can lead to short stature.
You can't be picky about food if you want to grow up.
Some students are often stunted and short stature. Once investigated, most of them didn't have a good breakfast, mainly because the breakfast was insufficient in quantity and poor in quality. Children are an important period for growth and learning, and they also need calories most in their lives. They have to have four classes in a row all morning, and most of the main classes are arranged in the morning, so their mental and physical consumption is particularly high. A few hours after dinner the day before and the next morning, the blood sugar in the body has been consumed almost. If you don't make up the calories from breakfast, the blood sugar concentration will continue to drop, resulting in hypoglycemia, which is not conducive to growth and development. In order to maintain the high blood sugar level throughout the day, breakfast must be regarded as the most important meal of three meals a day.
In order to pursue physical beauty, some girls diet inappropriately and restrict their diet excessively, and their nutritional needs are not guaranteed, which will seriously affect their physical development and hinder their growth.
The child is in a long physical period and needs more nutrition. Because the child's organs are not mature, there are not many sugar sources stored in the liver and muscles, and they usually have a large amount of activity and consume more calories. Excessive dieting will inevitably lead to insufficient nutrition and calories, which will easily lead to hunger and fatigue. Over time, it will inevitably affect physical development and lead to slow growth.
Children who diet for a long time will also make the organs and tissues of the digestive system degenerate and shrink, and the digestive juice secreted by the digestive glands will decrease, causing serious indigestion and malabsorption. Over time, it will form a vicious circle of anorexia ~ indigestion ~ malabsorption ~ anorexia. Severe patients will be life-threatening due to acidosis. How can it not affect the increase?
Studies have shown that the most common short stature caused by endocrine diseases is the direct or indirect lack of growth hormone. Nutritional disorders, such as zinc deficiency, iodine deficiency, calcium deficiency and iron deficiency. , zinc deficiency dwarfism, cretinism-like dwarfism, calcium deficiency syndrome, etc. , is one of the reasons for short stature.
All the nutrients people need come from food and food. As the saying goes, "a good figure is edible." As we all know, food is the material basis for ensuring life and health. The ancients once concluded: "Five grains are the supplement, five fruits are the help, five livestock are the benefit, five vegetables are the filling, and the smell is combined into essence." Neijing said: "All fruits and vegetables in the grain can be eaten and nourished." It is said that five grains, five fruits, five animals and five dishes should be eaten alternately. More than 2,000 years ago, it was still so real and useful. It can be seen that the increase of diet therapy is achievable. As far as the current dietary structure is concerned, it is difficult for pregnant women and children to meet their physical needs from the general diet. About 30% pregnant women and 40% children are in the marginal state of zinc deficiency and iodine deficiency is more serious.
The increase of dietotherapy should grasp four periods: fetus, infancy, childhood and adolescence (including pre-adolescence). Three meals a day, coarse and fine, animal food and plant food should have a certain proportion, it is best to eat some beans, potatoes and fresh vegetables every day. Eat foods and foods rich in zinc, iodine, calcium, iron, manganese, selenium and vitamins, such as animal liver, meat, fish, clams, oysters, kelp, seaweed, mussels and animal bones, especially cereals and beans. For children, we should pay more attention to the supply of nutrition, and don't restrict it too much. Children should eat not only staple food, but also non-staple food. The staple food should not be too fine. We should eat coarse grains and miscellaneous foods, such as tofu, mashed vegetables, minced meat, eggs, fish soup, cereal, rice oil and bran cakes.
Not long ago, the Nutrition Society of China officially published the Dietary Guide for China Residents and recommended it to the society. This is a great event and great merit. It will help China's population of 654.38+0.2 billion to put three meals a day into the scientific track, and play an important role in developing China's food civilization and improving the physical fitness of the Chinese nation.
