Summary
Brief summary (as posted)
The purpose of the study is to evaluate the feasibility and acceptability of a dietary intervention (FEED-FF) that includes fermented foods (FF), among locally advanced rectal cancer patients and non-small cell lung cancer (NSCLC) patients, and to explore whether this diet can improve outcomes in rectal cancer patients receiving chemoradiation and NSCLC patients receiving immunotherapy.

- description
- Participants will be asked to pick up the fermented foods at the Research Kitchen at Moffitt. Participants will be asked to eat 3-6 servings of FFs per day, from 1 week prior to treatment start through 12 weeks after treatment start/until the restaging scope is completed. At baseline, the end of week 6.5 and again at week 12.5, participants will be asked to provide biospecimens including a stool sample collected at home and a blood specimen collected in clinic. Participants will be asked to complete a food frequency questionnaire, a quality-of-life survey, two symptom related surveys, and a stool collection questionnaire at these same timepoints. After the dietary intervention, participants will be asked to complete an exit survey to provide feedback on the study and intervention.

- description
- Participants will receive general healthy eating handouts similar to current usual care documents provided in clinic. These handouts will detail typical healthy foods and the suggested level of intake, or servings per day. At baseline, the end of week 6.5 and again at week 12.5, participants will be asked to provide biospecimens including a stool sample collected at home and a blood specimen collected in clinic. Participants will be asked to complete a food frequency questionnaire, a quality-of-life survey, two symptom related surveys, and a stool collection questionnaire at these same timepoints.
