Try not to eat fish during your child’s cold and cough. Among the fishy foods, fish foods such as carp, scallops, tuna, etc., can potentially aggravate a cough. Some children with coughs continue to get worse after eating fish food, which is usually related to the fishy taste that irritates the respiratory tract and the body’s allergy to fish and shrimp food proteins. Moreover, the body’s gastrointestinal function decreases during a cold, and the digestive capacity is reduced, so it is not easy to absorb fat. If you eat a lot of fish, these fats are easily distributed in the esophagus and throat area, affecting the discharge of secretions. Eating a lot of fish can also affect the effect of cough medicine, so you should eat less fish, shrimp and meat during the cough period to avoid fire and phlegm. You can eat more snow pear, apple, loquat fruit, white radish, lily, honey and winter melon, which have the effect of removing phlegm and clearing the lungs. It is better to keep your diet as light and easy to digest as possible during a cold and cough, as this will help you recover from the disease.
