Can black fish be consumed as a tonic for a prolonged period?

Generally speaking, snakehead fish can be consumed long-term as a tonic, but it should be done in moderation. The detailed explanation is as follows:

Snakehead fish is rich in high-quality protein, whose amino acid composition closely matches the body's requirements, making it easily absorbed and utilized. Long-term consumption can supply the body's protein needs, maintaining normal muscle and tissue repair and growth. Additionally, snakehead fish contains various minerals such as calcium, phosphorus, and iron, as well as nutrients like B-complex vitamins. Calcium and phosphorus contribute to bone health, iron participates in hemoglobin synthesis, and B-complex vitamins help regulate metabolic processes. Together, these nutrients provide continuous nutritional support to the body, making snakehead fish suitable for long-term consumption as a healthful food.

When consuming snakehead fish regularly, ensure the freshness of the ingredients. Cooking methods should primarily be light, such as steaming or making soup, avoiding excessive frying or braising. Eating it 2-3 times per week is sufficient. Combine it with vegetables, coarse grains, and other foods to ensure a diverse diet. It is not recommended for individuals allergic to fish. If symptoms such as skin itching or diarrhea occur after consumption, stop eating it immediately and monitor your physical condition. When purchasing snakehead fish, choose reputable sources to ensure product safety.
