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 makes many young mothers and fathers start to worry about whether their babies will get asthma. The following experts from Jinan Asthma Hospital will introduce the principles of prevention and treatment of pediatric asthma that young parents should pay more attention to in their daily lives, so that 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 when they have a wheezing attack, 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, 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. Second, it is advisable to eat more food rich in vitamin a, b, c and iron, calcium Vitamin a has the function of maintaining normal human 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. In addition to the function of promoting growth and development, calcium also has functions such as anti-allergy. In addition, the body in order to improve the uptake of oxygen from asthma hypoxic state to reduce tissue hypoxia, there will be compensatory iron deficiency, and the supplement must be increased accordingly. Especially when the acute attack of asthma occurs, the water loss through the respiratory tract does not increase, and the child is prone to dehydration, and the airway sputum will become sticky and not easily discharged. Cold drinks and carbonated beverages The airways of children with asthma are in a highly reactive state, and cold stimulation can often induce airway spasms and cause asthma attacks, while carbonated beverages often have added ingredients such as flavors and colors, which are harmful to the human body, and the carbon dioxide gas they contain is also bad for the lungs. Fifth, 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, diaphragmatic uplift, limiting the ventilation of the lungs, and can also induce asthma, so children with asthma should try to avoid such food intake. Sweet and salty food can produce phlegm heat, and too sweet and salty food may induce asthma attacks, so the diet of children with asthma should be relatively light.
