I've had açaí berries, being one of those Americans who longs to be healthier, especially if I can do it by plopping a few berries into a smoothie.
Açaí, which to me taste a little like dull blueberries, reportedly brim with antioxidants, vitamins and fiber. They are said to promote energy, healthy digestion, and even a dewier complexion.
But how do açaí berries get from the tops of trees in Brazil's Amazon into the açaí bowls that sell in San Francisco, Austin and West Des Moines?
Many are picked by children.
