Children are allergic in spring, so parents should pay attention to their daily life, eat properly and exercise properly. First, in early spring, the temperature is still cold. Stimulated by cold air, hyperthyroidism consumes calories and weakens human endurance and resistance. Therefore, the diet is still dominated by high calories. In addition to beans, you can also eat glutinous rice products, soybeans, sesame powder, peanuts, walnuts and other foods, and should supplement high-quality protein, such as eggs, shrimp, fish, beef and other foods, which are rich in amino acids and have the effect of increasing human cold tolerance. Besides, we should take in enough vitamins and minerals. For example, vitamin D has antiviral ability, and foods rich in vitamin D include Chinese cabbage, tomato vegetables and fruits such as oranges and lemons. On the other hand, vitamin A can protect and enhance the function of upper respiratory mucosa and respiratory epithelial cells, thus resisting the invasion of various pathogenic factors. Foods rich in vitamin A include carrots. Vitamin E can improve human immunity and enhance disease resistance. Foods rich in vitamin E include cabbage, cauliflower, sesame and so on. In addition, auricularia auricula and mushrooms are also indispensable foods. Then there should be appropriate outdoor activities to improve the body's disease resistance, which is of great benefit to prevent spring allergies. I hope the above answers can help you!
