Introduction
Eating fish may promote phlegm production. Fish is considered a “pungent and rich” food, containing abundant protein and fat. Excessive consumption can lead to nutritional excess in the body, triggering symptoms of “excess heat” (a traditional Chinese medicine concept). This is especially true for individuals with weak spleen and stomach function—whose digestive capacity is already compromised—since consuming fish may impair water metabolism, resulting in increased salivation and subsequent phlegm formation.

Fish is classified as a “pungent and rich” food in traditional Chinese medicine, containing abundant protein and fat. Excessive consumption can lead to nutritional excess and internal heat (“fire”) symptoms—particularly in individuals with spleen- and stomach-qi deficiency. Due to their weakened digestive capacity, such individuals may experience impaired water metabolism after eating fish, resulting in increased salivation and subsequent phlegm formation. Therefore, people with spleen- and stomach-qi deficiency should avoid excessive intake of pungent, rich, greasy, or sweet foods, and instead opt for light, easily digestible meals. Additionally, individuals with allergic constitutions may develop allergic reactions after consuming fish, leading to increased airway secretions and symptoms such as phlegm in the throat, sore throat, and pharyngeal swelling. If one experiences phlegm sensation in the throat after eating fish, digestive-supportive medications—such as Compound Chicken Gizzard Powder (Fufang Jineijin San) or Qingjin Huatan Tang—may be used under medical supervision to help resolve phlegm.
Although fish is highly nutritious, moderate consumption during periods of good health can enhance physical constitution and immunity. However, caution is advised when consuming fish during illness or when experiencing any discomfort.
