Intervention

Dietary Supplement:
• 1 Serving of broccoli sprouts
Participants will take 1 serving of broccoli sprouts daily for 28 days. The sprouts will be provided by the study team along with instructions on how to prepare the steamed broccoli sprouts (i.e., steamed for 10 minutes). In addition to taking the sprouts, participants will be asked to complete food diaries and surveys, collect blood and stool samples, as well as having 2 in-person visits.
• 3 Servings of broccoli sprouts
Participants will take 3 servings of broccoli a day for 28 days. The sprouts will be provided by the study team along with instructions on how to prepare the steamed broccoli sprouts (i.e., steamed for 10 minutes). In addition to taking the sprouts, participants will be asked to complete food diaries and surveys, collect blood and stool samples, as well as having 2 in-person visits.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility of adopting a steamed broccoli diet in patients with ulcerative colitis as measured by self report of difficulty eating broccoli sprouts.	Self report documented in the end of study questionnaire. The questionnaire has 11 questions with the feasibility specifically linked to question 7, "how difficult was it to eat broccoli sprouts?" The answers range from 'not at all' (1) to 'very hard' (5) on a likert like scale.	Day 28
Primary	Feasibility of adopting a steamed broccoli diet in patients with inflammatory bowel disease ulcerative colitis as measured by participant compliance.	Compliance is collected through self-report of the number of servings consumed.	Day 28
Primary	Levels of sulforaphane in the stool	Level recorded in micrograms/gram.	Day 28
Primary	Levels of sulforaphane in the blood	Level recorded in micrograms/gram.	Day 28
