    Number of grams of solid fat and percent of intake from solid fat consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

    2003-2014

  • Added sugar

    Number of grams of added sugar and percent of intake from added sugar consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

    Cup-equivalent servings of non-starchy vegetables consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

    2003-2014

  • Whole fruit

    Cup-equivalent servings of whole fruits consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

    2003-2014

    Ounce-equivalents of whole grains consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources).
