FOODS
Traditional New Year foods are also thought to bring luck. Many cultures believe that anything in the shape of a ring is good luck, because it symbolizes "coming full circle," completing a year's cycle. For that reason, the Dutch believe that eating donuts on New Year's Day will bring good fortune.
Many parts of the U.S. celebrate the new year by consuming black-eyed peas. These legumes are typically accompanied by either hog jowls or ham. Black-eyed peas and other legumes have been considered good luck in many cultures. The hog, and thus its meat, is considered lucky because it symbolizes prosperity. Cabbage is another "good luck" vegetable that is consumed on New Year's Day by many. Cabbage leaves are also considered a sign of prosperity, being representative of paper currency. In some regions, rice is a lucky food that is eaten on New Year's Day.
