This project is a five-year study funded by the National Cancer Institute and conducted as a subaward with Drexel University. The research team is testing an intervention designed to help adults adopt and sustain eating patterns that align with international dietary guidelines for cancer prevention. The program focuses on improving the home food environment and engaging household members to support healthy eating behaviors. Findings from this study will contribute to understanding how multi-level, family-based strategies can promote long-term dietary change and reduce chronic disease risk.
