Eatwell Clinical Trial (R01)

Cancer is a leading cause of death and will affect many people in their lifetimes. Organizations such as the American Cancer Society and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) have noted that dietary quality is a key factor influencing cancer risk, but most Americans do not meet these dietary guidelines for cancer prevention. The proposed study will enroll adults from the community (n=236 index participants, 236 household members; N = 472) who have low adherence to WCRF/AICR's four dietary guidelines. Participants will be randomized to either nutrition education or the Eatwell intervention. The Eatwell intervention content is focused on helping participants make healthier grocery shopping decisions, eat at home more often to take advantage of the optimal defaults present there, and learn how to navigate temptation when eating away from home. The findings will be relevant not only to the field of cancer prevention, but to the prevention of other diseases for which dietary quality is important.
