Eating bird's nest is for health, so it is not surprising to introduce bird's nest into the health center. But remember to find the right brand of bird's nest to ensure the quality of the purchase. The quality of a well-known domestic bird's nest brand like Tianfu Yan can be assured. The main nutrient in bird's nest is protein, which contains 1 essential amino acid (lysine) and 3 kinds of conditionally essential amino acid, while human body needs 8 kinds of essential amino acids and 13 kinds of conditionally essential amino acid. The bird's nest industry started late in China, and there was a small development peak in 1990s. However, according to the survey data of relevant departments, the small climax of the bird's nest industry in the middle and late 1990 s was mainly because merchants saw that the bird's nest market was profitable and switched from other industries to the bird's nest industry market. However, due to uneven qualifications, upstream procurement cannot be guaranteed, and a large number of inferior and counterfeit products flood the whole market, leading to "short life" in market development.
