Potato Chip (American English) or Crisp (British English) is a thin slice of potato that has been deep fried or baked until crunchy. Potato chips are commonly served as a snack, side dish, or appetizer. Potato chips are a predominant part of the snack food market in Nigeria. A baked potato is more nourishing choice than a fried potato given that starch subjected to high heat cooking forms acrylamide, a potent carcinogen. Potatoes as a world food are second in human consumption only to rice.
