Zesty ingredient with a punch was initially thought to boost the sexual desire of women; today indulging is seen as a form of social bonding

It is not an exaggeration to say that chilli peppers and spicy food are available on pretty much every street in China.

The pungent, heat-infused foodstuff is so ubiquitous people joke that if a person does not indulge, they will starve, or at best lose friends, because eating spicy things fosters social bonding.

However, the popular ingredient has only been around in China for a relatively short time.

It first entered the country 400 years ago and people have been eating it for about three centuries.

This is revealed in a book titledThe History of Chinese People Eating Chili Peppers, written by Cao Yu, a researcher from Sun Yat-sen University in southern Guangdong province.
