The federal Supplemental Nutrition Assistance Program—known as SNAP nationally and CalFresh in California—provides food benefits to over 22 million low-income families in the US to supplement their grocery budget. New Nutrition Policy Institute (NPI) research demonstrates that sending encouraging text messages to SNAP participants helps promote nutrition resources and stimulate positive feelings about the program. NPI researchers collaborated with the University of California, San Diego, Center for Community Health, to partner with the San Diego County Health and Human Services Agency to send 5 monthly behavioral science-informed nutrition text messages to approximately 170,000 CalFresh participants. The text messages were sent in English and Spanish and provided information about the benefits of buying and consuming California-grown fruits and vegetables. Each text-message included a link to a  website which provided information about selecting, storing, and preparing fruits and vegetables, and budget-friendly recipes. Results highlighted that participants gained better knowledge on these subjects, as well as feeling good about participating in CalFresh and appreciating the program's efforts to help participants eat healthfully. Survey results demonstrated that 90%  of respondents appreciated the text-messages. This research brief demonstrates that further communication efforts through text-messages from SNAP agencies can help program participants eat more healthfully and improve their views on SNAP. The brief was developed by NPI researchers Celeste Felix, Ron Strochlic and Wendi Gosliner and Sena Karvas from the University of California, Berkeley School of Public Health.
