Saliva

People call saliva the liquid that we secrete while chewing food. It is not water as some may think because saliva contains 98 to 99% water. It also contains salts, proteins, lipids, carbohydrates and some vitamins. Saliva has important functions:

It liquefies food - it is thanks to the presence of amylase that salivary fluid is able to transform complex carbohydrates into easily digestible ones. Reduces temperature - thanks to the enzymes contained in the composition, the digestion process improves and the proliferation of bacteria is suppressed
