Results for All Students. Overall, vegetables had the lowest median percentage consumed of
any of the food groups, at 68 percent, whereas the median percentage consumed for each of the
other four food groups was 100 percent (see Table V.1). Fully 58 percent of participants who had a
vegetable at lunch consumed less than 90 percent of it, and 25 percent of participants consumed less
than 45 percent. The distribution of the percentage consumed of the other food groups was much
more concentrated in the range of 90 to 110 percent.
