Digestive function: Saliva can "bundle" chewed food into "food balls", which facilitates swallowing. At the same time, saliva contains amylase, which can break down the starch in food into maltose, which not only makes people feel sweetness but also allows food to enter the digestion process in the mouth. Anti-inflammatory effect: Saliva contains antibacterial components such as lysozyme and secretory immunoglobulin A, which can inhibit or eliminate hemolytic streptococci, typhoid bacilli, Escherichia coli and Staphylococcus aureus, thereby preventing inflammation of the gums, mouth and throat. Cleansing effect: The average daily saliva secretion per person can reach 1000-1500 ml. Food residues accumulate in the human mouth, creating conditions for bacterial growth. The constant flow of saliva in the mouth is equivalent to timely cleaning of the teeth, thus keeping the mouth clean and healthy.
Tooth protection function: The nutrients contained in saliva, such as sodium, potassium, phosphate, calcium, protein, glucose, etc., can maintain the acidity and alkalinity of the oral cavity and regulate the pH value. The dissolution and deposition of enamel on the tooth surface is a dynamic process. Calcium ions, phosphate ions and fluoride ions in saliva play an important role in protecting enamel. Healing effect: Dutch researchers found that histones rich in human saliva can significantly shorten wound healing time. Therefore, if you are suddenly injured and it is inconvenient to clean the wound, you can apply some saliva on the wound. Anti-cancer effect: Japanese researchers have found that saliva can eliminate superoxide free radicals produced by carcinogens. The disinfection process of saliva not only takes place in the mouth, but also lasts for 30 minutes in the stomach. Chewing each mouthful of food 30 times can allow saliva and food to be fully mixed, clearing free radicals to the greatest extent, achieving the best anti-cancer effect. Detection: Scientists can use saliva samples to check the level of drugs in patients. Using saliva instead of blood samples to test for HIV has also begun to be applied in practice. Currently, scientists are also studying ways to detect diseases such as diabetes, heart disease, and cancer through saliva. Saliva sampling is simple and easy to operate, and will become a trend in medical development.
Anti-aging effect: Saliva contains a "parotid hormone" that can keep people young, make people smart, have strong teeth and strong muscles, so that even in old age, people will have rosy complexion and remain youthful and energetic. It can be seen that "saliva" is precious and cannot be wasted or discarded at will. We should be good at promoting the secretion of saliva to achieve the purpose of strengthening the body, maintaining health and prolonging life. |
