Aquatic products are not only delicious, but also the source of high-quality food protein, with high amino acid content and delicious taste. Excluding water and dry matter, the protein content in aquatic products is as high as 80% ~ 90%, with low fat content, high unsaturated fatty acid content and few connective tissues, which is easy to digest and absorb, and is especially suitable for the elderly and children.
Aquatic products are rich in multivalent unsaturated fatty acids, which can improve intelligence and strengthen brain. Among various nutrients in aquatic products, EPA, DHA and arachidonic acid are the most important components, among which DHA is the famous "brain gold" and EPA is called "vascular scavenger". These nutrients have great benefits for improving human memory function, lowering cholesterol and protecting cardiovascular and cerebrovascular diseases, and are rich in fish, especially marine fish, shellfish and soft-shelled turtles.
Aquatic products are also good food for human beings to supplement minerals, vitamins and other trace elements. Marine fish liver is an important source of vitamin A in medicinal fish liver oil. Oysters are rich in zinc and copper, Monopterus albus and crabs are rich in riboflavin, algae are rich in carotene and iodine, and the calcium content of shrimp skin per 100 grams is 20 times that of milk, and so on. Research and practice have proved that aquatic products are one of the natural foods with the best nutritional balance for human beings and can play a positive role in health and longevity.
