Flavours activate saliva immune defence
Tasty food is “mouth-watering”. However, saliva I so much more than water: It contains mucosal and immune cells as well as a large number of molecules that perform a wide variety of biological functions such as ensuring healthy teeth, gums, and oral mucosa. Moreover, saliva is the first barrier against pathogens. Therefore, it also contains a number of antimicrobial molecules, including the antibacterial lysozyme. These are part of the innate molecular immune system.
