Although there are no special “taboos” in food intake for children with congenital heart disease, it is important to properly control the intake of certain foods for the rehabilitation of children after surgery. 1, strictly control the intake of salt. The main components of salt are sodium and chloride, and sodium in the body has the role of “hydration” tissue, most of the sodium and chloride in the body are excreted from the urine. The high concentration of sodium ions in the blood will cause a large amount of water retention in the body, resulting in edema, liver enlargement, increased burden on the heart, and in severe cases, heart failure. At the same time, excessive salty diet is also one of the important causes of hypertension. Therefore, the diet of children with congenital heart disease after surgery must be lighter, pickled products, salted eggs, salted fish and other foods containing too much salt should not be eaten as much as possible. 2, should not eat more chocolate and other sweet food. After heart surgery, when children do not want to eat, many parents like to stuff chocolate to children to eat, thinking that this can ensure nutrition. The main components of chocolate are fat and sugar, which are high in calories, but the ratio of protein and fat contained in it differs greatly from the normal needs of children. Eating more chocolate is likely to cause indigestion, constipation and loss of appetite in children. At the same time, chocolate contains caffeine and other ingredients, consuming too much will not only make children overexcited, affecting the rest, but also on the brain development of children bring certain adverse effects. 3, should not eat more canned beverages and cold drinks. At present, the market is sold in a wide variety of canned beverages, many drinks are mainly composed of sugar or saccharin, spices, coloring and water, but often insufficient nutrition. Cold drinks are also popular among children, but the digestive organs of children after major surgery are still in the recovery and adjustment stage, and the digestive function of children is often weak at this time. Too cold food into the stomach will stimulate the gastric mucosa vasoconstriction, gastric juice secretion is reduced, affecting the digestive process of food in the gastrointestinal tract; at the same time will also weaken the gastrointestinal tract’s bactericidal ability, resulting in infectious diseases of the gastrointestinal tract. 4, should not be blindly tonic. Some parents believe that ginseng has a tonic effect, so they give their post-operative children ginseng soup. Ginseng does have the function of strengthening the heart and body, replenishing qi and generating fluid, but different ginsengs have different properties, and improper consumption may cause symptoms such as loss of appetite, nose bleeding and restlessness. There are also some supplements that are not suitable for children during their growth and development. The best post-operative “tonic” is natural food. Parents just need to follow the above-mentioned principles, pay attention to the meat and vegetables in the child’s daily diet, coarse and fine balance, pay attention to prevent the loss and destruction of nutrients when cooking, to ensure that the three meals a day to eat enough, eat well, the child will certainly recover strength as soon as possible.
