Partial eclipse doesn't necessarily mean that you only eat one kind of food, and you won't be short of vitamin A. For example, he loves meat, and he is unlikely to eat only meat all his life, but he still wants to eat bean noodles, vegetables, fruits, melons and vegetables. If this person must only eat rice or noodles, this situation may not happen. Take the biological world for example. Lions, tigers, cats, wolves and other carnivores also eat grass moderately to promote digestion. Only some kinds of insects eat only one kind of plant, and there is no lack of nutrition. People are extremely complex and high-end microorganisms, of course, the diet is more complicated. If you only eat a single food crop, it is definitely not good.
First of all, we should establish and correct the cause of nutritional deficiency, actively supplement the lack of nutritional elements when nutritional deficiency occurs, and control the caloric value of dietary intake according to the doctor's advice when nutritional overflow occurs. The actual and reasonable diet is based on the cause of the disease. If the disease leads to nutritional deficiency, it is very likely that drug treatment and nutritional supplement must be carried out according to the doctor's advice on the premise of a balanced diet. People who lack nutrition due to weight loss should ensure that the various nutrients they consume every day meet their physical needs.
Diet collocation is one of the most important things in the process of malnutrition. Because children who are already in a long physical link need protein, whether it is the growth of bone cells or the growth and development of muscle tissues and internal organs, protein should be supplemented for malnourished children. Eating milk, peanuts, lean meat, shrimp, eggs, beans and other foods rich in protein, soybean lecithin and calcium hydrogen phosphate is beneficial to brain development and physical growth.
