Precious Sialic Acid

Nowadays, bird’s nest is the gift of choice when it comes to giving to the elderly. What makes bird’s nests so beneficial to the elderly? Why are they so expensive? Let us explore the contents of bird’s nests.

Bird’s nests contain three different types of nutrients, namely, Sialic acid (N-acetylneuramic acid, Epidermal Growth Factor (EGF) and Colony Stimulating Factor (CSF).

Main Nutrient Contents in Bird’s Nests

According to the research of medical professionals, the main contents in bird’s nests are soluble proteins and carbohydrates. Moreover, bird’s nests contain other trace elements required by the human body, such as calcium, phosphorus, iron, sodium, potassium, amino acid and more. Amino acid could boost digestion in the human body. 1,000 gram of dry bird’s nest contains 50% protein, 30% carbohydrates, 10% moisture and approximately 10% of trace elements. Such rich nutrient contents could not be found in other supplements.

Main Functions of Bird’s Nest Nutrients

1. Protein

Bird’s nests contain high levels of protein, which is vital for the regeneration of human tissues and has a magical effect on the human body’s growth and recovery. The 30% carbohydrate could provide calorific capacity to the human body, promoting fat metabolism and detoxification.

Besides that, the soluble protein would stimulate cell division and regeneration. This is very helpful in the body’s recovery. This is why bird’s nests are usually presented as gifts when a person falls sick or after he/she has undergone surgery.

2. Trace elements

  • Calcium can increase the blood coagulation rate after skin damage. It can also help the body to absorb Vitamin B12.
  • Rich mineral elements – sodium, iron and potassium can work together with protein for the division and regeneration of human cells and tissue reconstruction.

3. Sialic Acid

  • Sialic Acid has an antiviral function. Generally, flu viruses have a structural protein called HA acting as a bridge, causing virus particles and the Sialic Acid in glycoproteins on the surface of the host to react and bringing the virus into the human cells. Sialic Acid could prevent virus particles from reacting with the Sialic Acid in glycoproteins and thus effectively preventing the human body from the invasion of viruses.
  • Sialic Acid can also boost the body’s immunity. Since the human body’s immunity is based on the structure of polysaccharides in Sialic Acid, consummation of a certain amount of bird’s nest would increase the stability of the structure of polysaccharides in Sialic Acid and hence, produce immunity toward more familiar antigens.
  • As we increase our understanding towards bird’s nest, we discover its benefits to the human body. A good example is Sialic Acid. This is also why the price of bird’s nest is higher.

4.   Other functions of bird’s nest

Research found that bird’s nest is also helpful for colds, as Sialic Acid could prevent the cold virus from invading the body further. Furthermore, Sialic Acid could not be broken down by digestive enzymes in the body and could resist viruses for a longer term. Based on this, we can develop a new cold medicine with our knowledge of Sialic Acid. Besides this, Sialic Acid can also resist the invasion of influenza viruses, respiratory viruses and other viruses. As such, it is very beneficial to the human body.

Due to the beneficial effects of bird’s nest, there are more and more pharmaceutical researches done on bird’s nests. Nowadays, bird’s nest is not only consumed as a tonic but also applied in various food and drugs.
