Spring is a high season for allergic asthma, especially for young children who have low body resistance and immunity and are not fully developed, and are the largest group of people affected. This has caused many young moms and dads to start worrying about whether their babies will get asthma. Here are some of the principles of prevention and treatment of pediatric asthma that young parents should pay more attention to in their daily lives, the “three preferences” and “three taboos”. The three main nutrients, namely protein, carbohydrates and fat, should be matched appropriately. Children with asthma are often in a state of oxygen deprivation during wheezing episodes, resulting in a weakened gastrointestinal digestive and absorption function, a loss of appetite and reduced feeding, which affects their normal growth and development. Therefore, children with asthma should be supplemented with sufficient high-quality protein such as milk and eggs, which accounts for about 35% of their nutritional intake. Carbohydrates, such as rice and flour, are the main source of energy 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. The second advisable: it is advisable to eat more food rich in vitamin a, b, c and iron, calcium Vitamin a has the function of maintaining the normal development of the body and enhance the body’s ability to resist disease. Vitamins b and c are important substances involved in various metabolisms, and have the role of increasing appetite and promoting the absorption of inflammation in the lungs. In addition to the function of promoting growth and development, calcium also has anti-allergy and other functions. In addition, the body in order to improve the uptake of oxygen from asthma hypoxia , to reduce tissue hypoxia, there will be compensatory iron deficiency, supplementation must be increased accordingly. Three desirable: it is desirable to drink more water Especially when the acute attack of asthma, the unmanifest water loss through the respiratory tract increases, the child is prone to dehydration, and the airway sputum will become sticky and not easy to discharge, so it is desirable for children 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 the carbon dioxide gas they contain is not good for the lungs. Second avoid: irritating foods and gas-producing foods There are chili peppers, 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, diaphragm upward, limiting lung ventilation, and can also induce asthma, so children with asthma should try to avoid such food intake. Three taboos: diet too sweet, too salty Sweet, salty food can produce phlegm heat, too sweet, too salty food may induce asthma attacks, so the diet of children with asthma should be relatively light.
