Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. Determine the intervention's feasibility and acceptability.
SECONDARY OBJECTIVES:
I. Estimate the effect of the intervention on the percent of grains consumed that are whole.
II. Estimate the effect of the intervention on total fiber intake (grams per day \[g/d\]).
EXPLORATORY OBJECTIVE:
I. Assess convergence of the reinforcement learning (RL) algorithm.
OUTLINE:
Patients receive nutrition education materials and then receive the adaptive text message intervention for 12 weeks on study. Patients who are food insecure also receive resources for food banks, information about meal delivery programs, and support for applying for Supplemental Nutrition Assistance Program (SNAP) benefits.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Text message intervention
Adaptive 12-week text message intervention using reinforcement learning to increase whole grain and reduce refined grain intake. Participants will also complete semi-structured follow-up interviews and study related questionnaires.
Dietary intervention via Text Messaging
Text messages will be sent to participants cell phones using the HealthySMS platform
Survey Administration
Various questionnaires evaluating participants dietary habits and use of study intervention will be administered
Nutrition Education
Participants will receive nutrition education materials
