Cold patients can generally eat seafood unless they are allergic to it. The common cold is the most frequently seen acute upper respiratory tract infection in clinical settings, and it is a contagious disease. It can cause a variety of clinical symptoms such as fever, cough, nasal congestion, runny nose, and sore throat. Therefore, patients with a cold will experience certain consumption, including nutritional and fluid loss. Seafood is the most common marine product food, and it does not affect the common cold. This means that eating seafood does not worsen the clinical symptoms of a cold. Moreover, seafood contains rich nutrients, which can beneficially supplement the losses caused by the cold. Of course, a very small number of cold patients may have an allergic constitution and be allergic to seafood, in which case it is not suitable for them, but this situation is very rare.
