Duck meat is known for its unsaturated fatty acids. Unlike the saturated fatty acids found in beef and pork, duck meat lowers blood cholesterol, which helps prevent lifestyle-related diseases. Furthermore, duck fat melts at 14 degrees, which is lower than body temperature, so it does not accumulate in the body. It is also rich in minerals and vitamins, and is said to have twice the iron of pork and three to five times the retinol (vitamin A) of beef and pork.The alliin released when scallions are cut enhances the glutamic acid and inosinic acid in duck soup, bringing out the umami of the duck meat to the fullest. Duck meat and scallions are a perfect match.
