Americans have grown broccoli in their gardens for about 200 years, but it was not popular until the 1920s. The first commercially-grown broccoli was grown and harvested in New York, then planted in the 1920s in California.
  • The name "broccoli" comes for the Latin word brachium, which means "branch," or "arm." Roman farmers called broccoli "the five green fingers of Jupiter."
  • Broccoli was first grown in the Italian province of Calabria and was given the name Calabrese.
  • Broccoli consumption has increased over 940 percent over the last 25 years.
  • Ounce for ounce, broccoli has as much calcium as a glass of milk and more vitamin C than an orange. A 1/3 pound stalk of broccoli has more vitamin C than 2 1/2 pounds of oranges or 204 apples.It is one of the best sources of vitamin A and has more fiber than a slice of wheat bran bread. Broccoli is also a good source of potassium, folacin, iron and fiber. It contains a few important phytochemicals: beta-carotene, indoles and isothiocyanates. Phytochemicals prevent carcinogens (cancer causing substances) from forming. They also stop carcinogens from getting to target cells and help boost enzymes that detoxify carcinogens.
