In spite of what Mother taught you about the benefits of eating broccoli, data collected by the U.S. government show that the nutritional content of America's vegetables and fruits has declined during the past 50 years -- in some cases dramatically.
Donald Davis, a biochemist at the University of Texas, said that of 13 major nutrients in fruits and vegetables tracked by the Agriculture Department from 1950 to 1999, six showed noticeable declines -- protein, calcium, phosphorus, iron, riboflavin and vitamin C. The declines ranged from 6 percent for protein, 15 percent for iron, 20 percent for vitamin C, and 38 percent for riboflavin.
