If anything could disarm a nuclear bomb, it would be kimchi — at least that’s what Koreans like to say. They eat kimchi several times a day, believing that the superfood can prevent and heal any kind of ailment, supposedly even broken bones. This may sound far-fetched, but Koreans swear by it.

Every culture has its own beliefs surrounding food and dining etiquette — often having to do with the healing powers of a certain food, whether it will bring good or bad fortune, or just a tradition that has lived on for centuries.

In Chinese culture, long noodles symbolize a long life. If you cut noodles before serving them to someone, you’re cutting short the life of that person. In Yoro, Honduras, it’s said that fish literally fall from the sky on one night of the year, called “lluvia de peces,” meaning “rain of fish.” 

And in France, hunger and misfortune will come to anyone who handles a loaf of bread upside-down or places it on the table upside-down.

They can seem like myths. But whether or not you believe them, many cultures live (and eat) according to these beliefs.
