Patients with cold and runny nose can eat some fish in moderation. Fish contains a large amount of amino acids, proteins and minerals, which can help patients recover their strength, replenish nutrition and strengthen their constitution, which is conducive to the recovery of the disease as soon as possible. The practice of fish should be steamed or stewed, and try not to add spicy and stimulating seasonings to avoid gastrointestinal discomfort. In addition, a small amount of fish can be eaten, but not too much, because too much protein is difficult to digest and may cause digestive symptoms, which is not conducive to health. Patients should pay attention to a light diet when they have a cold, eat foods that are easy to digest and rich in vitamins. It is usually recommended to eat mainly liquid or semi-liquid foods, such as rice porridge, thin rice, noodles, etc., and eat with fresh vegetables and fruits. At the later stage of recovery, you can eat more lean meat, fish or tofu and other high protein foods to help your body recover as soon as possible. Most of the common cold is caused by adenovirus, rhinovirus, parainfluenza virus and other infections, the main clinical manifestations are fever, headache, cough, nasal congestion, runny nose, etc. Most of the symptoms are mild and self-limiting, and can be cured by themselves in about a week.
