Chewing food properly is not just good for digestion, but can improve mouth's immune system protecting you against illness, according to a study released Thursday by The University of Manchester.

Scientists have known that food nutrients can contribute to a healthy immune system in the mouth, but the study, led by researchers from The University of Manchester and National Institutes of Health in the United States, shows that chewing food also plays an important role.

The team found that when you are chewing, the action will stimulate a specific type of immune cell -- the "Th17" cell.

In their experiment, the team changed the hardness of the food fed to mice, which caused more mastication. That stimulated the increases in Th17 cells in mice.

"The immune system performs a remarkable balancing act at barrier sites such as the skin, mouth and gut by fighting off harmful pathogens while tolerating the presence of normal friendly bacteria," says one of the study authors Joanne Konkel from The University of Manchester.

"Our research shows that, unlike at other barriers, the mouth has a different way of stimulating Th17 cells: not by bacteria but by mastication. Therefore mastication can induce a protective immune response in our gums," says Konkel.

However, it is not always good to have too many Th17 cells, which can lead to periodontitis.

Nontheless, "because inflammation in the mouth is linked to development of diseases all around the body, understanding the tissue-specific factors that regulate immunity at the oral barrier could eventually lead to new ways to treat multiple inflammatory conditions," adds Konkel.

maybe not in China.
they have a history of only 5000 years, while most Europeans have a history of 8000+ years.

they are only re-learning much that is taken for common sense after the death and suppression of intellectuals and scholars in the 1960's, and are very-much hampered for such information due to the censorship of the internet.

It is not wrong to let your body play its natural role including chewing!
Chewinng without food as soon as you wake up in early morning is useful for the teeth!
The most useful knowledge and skill that we are lack of is that of about human!
