Adherence

SNAP participants exhibit significantly lower diet quality and fail to meet American Heart Association (AHA) ideal diet goals compared to higher-income individuals, with disparities persisting or worsening for processed meats, added sugars, and nuts/seeds between 1999 and 2014.

For adults on SNAP, simply having access to food assistance does not guarantee adherence to heart-healthy dietary guidelines. Data shows that despite overall modest improvements in US diet quality, SNAP participants have not seen similar gains, with disparities worsening in key areas like processed meat and added sugar intake. Policy and individual interventions must address specific barriers to meeting AHA goals (fruits, vegetables, whole grains, limiting sodium/SSBs) rather than assuming income eligibility alone resolves diet quality issues.

Dietary disparities persisted or worsened for most dietary components among US adults. Despite improvement in some dietary components, SNAP participants still do not meet the AHA goals for a healthful diet.
