Blueberries are the second most popular in the berry bunch, behind strawberries.

This mildly sweet berry tops 60 fruits and vegetables in antioxidants, says Poletti. Blueberries are also jam-packed with vitamin C and fiber.

Average weekly blueberry sales per store were $747 in 2010, compared with $531 in 2006.

There are more than 200 million pounds of blueberries grown in North America every year, according to the Agricultural Council of America. Michigan and New Jersey produce 66 percent of all the blueberries in the U.S., followed by North Carolina, Oregon and Washington.

Total acreage increased from 52,002 in 2002 to 60,353 in 2007, according to the U.S. Department of Agriculture.
