Although seafood is rich in vitamins, trace elements, minerals, high quality amino acids and proteins, which can provide the body with rich nutrition and energy, seafood is a hairy substance from the perspective of Chinese medicine. Seafood can aggravate the decline in immunity when one’s immunity decreases during a cold, thus making the symptoms more pronounced. And especially for special types of colds, such as gastrointestinal colds, there will be nausea, vomiting, diarrhea and other symptoms, when eating seafood will increase the burden on the gastrointestinal tract and aggravate the symptoms. Especially for patients with chronic diseases, such as gout and very high uric acid in the blood, seafood contains very high purines, which will increase the uric acid in the blood and aggravate the symptoms of gout, and also aggravate the symptoms of cold, so do not eat seafood when you have a cold.
