Since ancient times, Chinese people have paid attention to "food supplements", that is, they believe that they eat what they eat. Therefore, things such as bird's nest and shark's fin are considered to be great supplements. I think there is no need to think so. From the advertisements of some experts and bird's nest manufacturers, we learned that bird's nest refers to the fact that swallows secrete saliva when they build nests to make the nests sticky, and the saliva secreted by swallows is the active ingredient of bird's nest products on the market. Bird's nest has been regarded as one of the traditional precious foods since ancient times. Bird's nest is rich in sugars, organic acids, free amino acids, sialic acid and other ingredients that are beneficial to the human body. It is said to have the effects of nourishing yin, moisturizing dryness, and replenishing qi. Under the advertisements of some brand bird's nest manufacturers, the endorsement of some so-called "experts", and the affirmation of some ill-intentioned researchers, bird's nest has become a beautifying effect. I think some of the effects of bird's nest are questionable.

Because ordinary bird's nests need to be cooked before eating, which is troublesome, some manufacturers have withdrawn from ready-to-eat bird's nests to solve the problem of some consumers eating bird's nests anytime and anywhere. But does the active ingredient of ready-to-eat bird's nest contain the active ingredient of bird's nest? Is ready-to-eat bird's nest effective?

Recently, professional anti-counterfeiters revealed on Weibo that the test report of a well-known bird's nest brand's ready-to-eat bird's nest showed that the ingredients in the brand's bird's nest were approximately equal to sugar water. This made the majority of netizens sigh. And those consumers who firmly believe that ready-to-eat bird's nest can beautify the skin and even extend life have undoubtedly paid the IQ tax.

Judging from some facts stated by some conscientious doctors and experts, it is not that eating these so-called "big tonics" will lead to beauty and good health. The method that more people mention to beautify and maintain good health is to maintain scientific and healthy eating habits, maintain a scientific work and rest, exercise appropriately, and maintain a happy mood. These are the most effective ways to keep us healthy. Don’t easily believe in things that can bring you health and beauty just by eating and using them.
