Bird's nest is secreted by swallowing saliva, and the main component is collagen. From the point of view of nutrition, protein contains essential amino acids. Collagen contained in bird's nest is not completely protein, and it is not necessary for life in nutrition. Skin, chicken feet and shark's fin also contain collagen, which can replace bird's nest in effect. After eating bird's nest every time, the amount of protein available to human body is limited, and its nutritional value is not high. Bird's nest is expensive, and it is good for people who lack nutrition to use other substitutes. Low price does not mean poor nutrition.

Bird's nest has no therapeutic effect, only a certain nourishing yin effect. However, we don't use bird's nest when treating patients with yin deficiency, it just plays an auxiliary role.

Bird's nest has the effect of improving skin, nourishing yin and reducing fire, but don't emphasize that bird's nest has great effect. There is a certain gap between the actual effect of bird's nest and the propaganda of many businesses.

It should be noted that we should have a correct concept of nutrition, do not form dependence on bird's nest, and do not eat bird's nest only when we are sick. Treatment is fundamental, eating bird's nest is auxiliary, and the cart before the horse cannot be put.

Many people I see will ask me if I can eat bird's nest, but no one says that eating bird's nest has a very good or very bad reaction.

"The body is not short of nutrition and does not need bird's nest tonic."

The standard of choosing nutritional products should be "adapting to one's own physique"

Comment expert: Mi, director of the Department of Traditional Chinese Medicine, School of Medicine, Xiamen University, and director of the Overseas Education Center of Traditional Chinese Medicine.

Bird's nest contains 57% or 4% nitrogen, as well as minerals, fat and sugar. These substances will indirectly help improve human immunity, especially for the lungs, kidneys and stomach.

For people who lack corresponding nutrition, taking bird's nest for a long time will indeed have certain effects; If the body does not lack nutrition, the effect of eating bird's nest tonic will be greatly weakened. It is best to choose the nutritional products that are most suitable for your physique according to your personal situation.

"Pregnant women eat bird's nest, which has little to do with the skin of mother and baby"

Pregnant women can choose tremella and mung beans. Instead of bird's nest nourishing yin.

Comment expert: Cai Liqian, nutritionist of Maternal and Child Health Hospital.

Nowadays, eating bird's nest is very popular among pregnant women. Many pregnant women think that eating bird's nest during pregnancy will improve the skin of mother and baby after delivery. In fact, there is no scientific basis for this. The spots produced during pregnancy are mostly caused by hormonal changes, and bird's nest is of little help. Many pregnant women will gradually fade after giving birth. The skin of normal fetus is mostly good, so pregnant women don't have to eat it specially.

Bird's nest is really helpful for pregnant women with fetal fever. But every pregnant woman's constitution is different, and pregnant women with cold constitution should not eat bird's nest. In addition, the price of bird's nest is high, which is difficult for many pregnant women to bear economically for a long time. Don't blindly follow the trend. In fact, you can also choose lily, tremella, mung bean and other foods instead of bird's nest, and the effect of nourishing yin is just as good.

Using bird's nest to supplement nutrition has little effect, even worse than eggs, fish, milk, meat, pig's trotters and so on.

In a word, we neither oppose nor advocate bird's nest tonic.

"Nourishing yin through bird's nest can nourish the skin"

Eating bird's nest alone has little effect on treating skin aging.

Comment expert: Weng Lili, director of health care department, director of beauty department and chief physician of Chinese medicine hospital.

The main ingredient of bird's nest is protein. According to the mechanism of TCM, it can be used in yin beauty. But it is not medicine, and it is impossible to cure the disease simply by eating bird's nest.

The indication of bird's nest is mainly yin deficiency constitution. Yin deficiency often manifests as dizziness, backache, dry mouth, and even patients with pulmonary tuberculosis in recovery period. People with tumor yin deficiency also belong to yin deficiency constitution.

Bird's nest can achieve beauty effect by nourishing yin. After eating bird's nest for a period of time, the skin will indeed regain its elasticity and become shiny. This is for skin care. However, drugs for tonifying kidney or qi and blood are generally used to treat skin anti-aging in clinic. When necessary, patients are advised to eat bird's nest to supplement collagen, and the combination effect of the two will appear. Eating bird's nest alone has little effect on skin anti-aging

"Bird's nest has the effect of assisting freckle removal"

Its active factor can inhibit the activity of black cells.

Comment expert: Xiu Zhifu, director of plastic surgery in Zhongshan Hospital, doctor of medicine, chief physician.

Bird's nest contains many digestive enzymes and active factors. On the one hand, digestive enzymes in bird's nest will help the human body digest and absorb. On the other hand, like honey, there are many complex active factors in bird's nest. Except for human placenta, honey and bird's nest, there are few such active factors in general foods.

Bird's nest can help people remove spots, because the active factors in bird's nest can inhibit the activity of black cells and enhance the antioxidant capacity of human body. So the effect of bird's nest in beauty beauty is still very good. It will make people's skin clean, shiny and ruddy.
