Chewing foods properly before you swallow boosts the mouth’s immune system and protects against illness.
Th17 immune cell is triggered by chewing, it protects against bacterial and fungal infections that are on the tongue and teeth.
Those who chewed each mouthful food for 40 times ate less than those who chewed for just 15 times.
Chewing for longer prevents over-eating by giving the brain signals from the stomach that it is full. It also lowers the levels of ghrelin, the hunger hormone.
