Only 38% of Americans consume the recommended daily servings of vegetables, and poor households buy less produce than others, according to a US Department of Agriculture report.

Some 19% of low-income households (versus 10% with higher incomes) bought no fruits and vegetables over a two-week period, with significant disparities in weekly fruit and vegetable purchases - US$3.59 per person for low-income households versus $5.02 for higher incomes - for both fresh and processed produce.

The most positive influence on expenditures is having a college-educated head of household, regardless of income. These households bought the most fruit and vegetables weekly, $5.99 per person.
