Can black fish enhance immunity?
Generally, snakehead fish can play a supportive role in maintaining the basic functions of the immune system, but it does not directly enhance immunity. When consuming snakehead fish, attention should be paid to appropriate portion sizes and cooking methods. Specific details are as follows:

Snakehead fish is a common aquatic food ingredient containing high-quality protein, B-complex vitamins, and minerals such as selenium and zinc. Eating moderate amounts of snakehead fish, prepared using light methods such as steaming or making soup, can help supplement these nutrients and typically does not cause adverse reactions. However, excessive consumption may burden the gastrointestinal system due to its high protein content, potentially causing discomfort such as bloating and indigestion. Moreover, snakehead fish does not contain any specific components that directly enhance immune function, so immunity cannot be improved simply by consuming it.
The snakehead fish must be thoroughly cooked to avoid parasitic or bacterial infection. Patients with gout should also consume it cautiously, as it contains certain levels of purines. In daily life, enhancing immunity should rely on a balanced diet, regular sleep patterns, moderate exercise, and a variety of fruits and vegetables combined with high-quality protein, which better supports immune system health.
