Asthma is a common chronic respiratory disease that seriously endangers children’s health. It has a high incidence, often manifests with throat sounds, and is a chronic course of recurrent attacks, which seriously affects the learning, life and activities of the affected children and the growth and development of children and adolescents. Many parents appear to be confused after their children develop asthma disease. Here are some dietary considerations about asthma in children. One appropriate: the three main nutrients, protein, carbohydrates and fat, should be properly matched. Children with asthma are often in a state of oxygen deprivation during wheezing episodes, resulting in a weakened gastrointestinal tract digestion and absorption function, loss of appetite and reduced feeding, which affects the normal growth and development of children. Therefore, children with asthma should be supplemented with sufficient high-quality protein such as milk and eggs, accounting for about 35% of their nutritional intake. Carbohydrates such as rice and noodles are the main source of energy for the body and should account for about 50% of the nutritional intake, but avoid over-eating gas-producing foods such as pasta, beans and potatoes. Fat intake should be small, accounting for about 15% of the nutritional intake. Because eating too much fat, affect appetite and gastrointestinal tract digestion and absorption, to the detriment of the disease, mainly by eating vegetable oils. Two appropriate: it is advisable to eat more food rich in vitamin A, B, C and iron, calcium. Vitamin A has the function of maintaining normal development and enhancing the body’s ability to resist disease. Vitamins B and C are important substances involved in various metabolisms and have the function of increasing appetite and promoting the absorption of inflammation in the lungs. Calcium has functions such as anti-allergy, in addition to the function of promoting growth and development. In addition, the body in order to improve the uptake of oxygen from asthma hypoxia to reduce tissue hypoxia, there will be a compensatory iron deficiency, and the supplement must be increased accordingly. Three desirable: it is advisable to drink more water. Especially when the acute attack of asthma, the water loss through the respiratory tract is not obvious, the child is prone to dehydration, and the airway sputum will become sticky and not easy to discharge, so it is advisable for the child with asthma to drink more water. A contraindication: cold drinks and carbonated beverages. The airways of children with asthma are in a highly reactive state, and cold stimulation can often induce airway spasm and cause asthma attacks, while carbonated beverages are often added with ingredients such as flavors and colors, which are harmful to the human body and contain carbon dioxide gas, which is also detrimental to the lungs. Second avoid: irritating food and gas-producing food. There are chili pepper, pepper, mustard, curry powder, coffee and other irritating foods, may induce airway spasm, so should try not to eat. Gas-producing foods such as groundnuts, potatoes, leeks, soybeans, pasta, etc., they tend to produce a lot of gas, resulting in bloating, diaphragmatic uplift, limiting the ventilation of the lungs, and can also induce asthma, so children with asthma should try to avoid such food intake. Three taboos: diet too sweet, too salty. Sweet and salty food can produce phlegm heat, too sweet and salty food may trigger asthma attacks, so the diet of children with asthma should be relatively light.
