We eat 20 percent fewer salads than we did twenty-five years ago, and only one in four meals contain an unprocessed vegetable. (That statistic would be even more dire if the lettuce on a hamburger were not counted as an unprocessed vegetable.) Only 49 percent of Americans ate a salad (just one!) in the last two weeks. Maybe 10 percent of our calories come from the unprocessed fruits and vegetables that should be the source of most of our calories.
