From a nutritional point of view, shark fin has no special nutritional value. Every100g shark fin (dry product) contains 83.5g of protein, 0.3g of fat, 0.46mg of calcium/kloc-0, 5.2mg of iron/kloc-0 and 0.94mg of phosphorus/kloc-0. It is a food with high protein and low fat, and is also rich in calcium and iron.

Although shark fin has a high content of protein, the quality of protein is not high. Because the protein of shark fin is mainly collagen, which belongs to an incomplete protein, its absorption and utilization rate is low, and its nutritional value is far less than that of protein from eggs, milk and meat. Many users think that this kind of collagen can beautify the face, but it is not necessarily, because all protein will be decomposed into amino acids after entering the human body, and many people don't understand that eating collagen can supplement collagen.
