First of all, we need to understand what is bird's nest and what are its main ingredients?
Bird's nest is a nest species secreted by several swiftlets of the swiftlet family and their down feathers, which are mainly distributed in Southeast Asia and coastal areas of Guangdong. Bird's nest is such a thing, but it needs to be processed to pick out the impurities in it in order to become a nutritious product in everyone's mouth.
The main nutrient in bird's nest is protein, of which there is only 1 essential amino acid (lysine), 3 kinds of conditional essential amino acids, while there are 8 kinds of essential amino acids needed by the human body, and there are 13 kinds of conditional essential amino acids. From this point of view, the nutritional value of bird's nest is very limited, and the price is not high. If you usually eat a moderate amount of meat, eggs and milk, plus moderate seafood, it is enough to obtain all the nutritional value that bird's nest can provide.
Wang Fengjun, director of the Department of Nutrition and Food Hygiene at China's Fourth Military Medical University, said that taking protein as an example, bird's nest is not as "high-quality" as eggs and milk. From the perspective of meeting the needs of the human body, the amino acid composition of bird's nest is not good, and the nutrition it can provide is incomplete protein, and the benefits to the human body are not as good as eggs and milk. Bird's nest contains proteins, trace elements and amino acids.
