4. Colds are very common, and both adults and children may encounter colds. Severe colds may be accompanied by fever, which should be noted. In addition to routine medication, it is also necessary to adjust the diet when you have a cold and fever. So, can you eat fish when you have a cold and fever?

1. There is a saying in traditional Chinese medicine that ‘fish generates fire, and meat generates phlegm’. When you have a cough or bronchitis, you should eat less fish, shrimp, crab, fatty meat, and others to avoid aiding fire and generating phlegm. In addition, greasy food tends to worsen coughing, which is not conducive to the recovery of colds and tracheitis. Therefore, a light and easy-to-digest diet is better for colds and coughs. Among all fishy-tasting foods, white crucian carp and hairtail fish are the most likely to worsen coughing symptoms, so patients should pay special attention to avoid eating these two types of fish. Some children with coughs may have worse coughing after eating fish, which is related to the stimulating effect of the fishy smell on the respiratory tract and protein allergy to fish and shrimp. Especially for children who are allergic to certain fish and eggs, it is necessary to avoid such foods.

2. Whether it’s a child’s common cold or bronchitis cough, it is not advisable to eat overly greasy foods. Greasy foods increase the burden on the intestines and stomach. For children who are sick, poor digestion also affects the recovery of the illness. Generally speaking, even a normal person may feel uncomfortable for three or two days after eating a greasy meal, let alone a sick child. Heavy meats and fish are absolutely not good for a child’s health. Therefore, parents should not think that their children need to be strengthened with chicken, duck, fish, and meat when they are sick. In general, the digestive function of cold patients has decreased, and it is not easy to digest and absorb fats. A large amount of oil and fat distributed in the esophagus and throat is also not conducive to the excretion of secretions. When the gastrointestinal function is out of order, undigested high-protein macromolecular substances such as eggs, lean meat, and fish can pass through the damaged gastrointestinal mucosa into the body, triggering certain allergic diseases. In summary, it is best not to eat fish when you have a cough and cold.

3. Common coughs in winter may cause symptoms such as skin redness, conjunctival congestion, dizziness, increased heart rate, urticaria, and others after taking cough medicine. This may be due to the patient eating deep-sea fish at the same time, with histamine being the culprit. Tuna, sardines, carp, and other fish contain a lot of histidine, and the bacteria remaining in the fish meat can convert it into histamine. This substance, when entering the bloodstream in large quantities, may cause an allergic reaction. Cough syrup contains codeine, which can promote the release of histamine, making it more likely to cause an allergic reaction.
