First of all, we should treat bird's nest rationally and not make accusations. We should neither brag it as a panacea that can cure all diseases, nor deny its nutritional value as a food itself. Bird's nest is rich in sugars, organic acids, free amino acids and characteristic substances - sialic acid, which has nutritional value. It has the functions of yin, moisturizing and replenishing qi.

The reason why bird's nest has always been controversial, I personally think, is that it is too expensive, which leads to people's high expectations for its positioning. They think that if it is expensive, it must have miraculous effects. In many cases, We have all overlooked the fact that bird's nest is just a kind of food (identified by the State Food and Drug Administration). Bird's nest has been severely demonized just because of its high price and bottomless publicity by some businesses. Depends on the purpose

If you eat it for the purpose of nourishing and beautifying the skin, then yes.

If you just think it tastes good, or show that you are rich by making others unable to eat the food, then no.

Bird's nest is formed by the condensation of saliva and down of some swifts and swiftlets, which contains proteins, amino acids, sialic acid, etc.

The protein and amino acids in bird's nest have nutritional value, but they are not irreplaceable. These proteins and amino acids can be well supplemented by eggs, meat, and fish, and they are much cheaper.

There is sialic acid in the human body and it plays an important physiological role, but it does not mean that eating sialic acid will also have an effect or be better for the body. Just like calcium ions are present in the human body and play an important role, but It does not mean that eating limestone with high calcium content will make your body better.

What we need to know is that only a few people in the human race regard bird's nest as food. No matter how expensive it is, bird's nest is essentially food, not medicine. None of the special effects it promotes have been confirmed. Taking expensive "supplements" can not only give yourself some psychological hints, but also remind outsiders: I am rich. Celebrities who endorse bird's nests become celebrities because they are celebrities, not because they eat bird's nests.
