Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a crossover trial. Participants will consume 3 marshmallows, 3 times per day (9 marshmallows in total) for 5 days and complete another 5 days with a marshmallow free diet. There will be a 2 day washout period.

Outcomes
Primary outcome [1] 289710 0
Mean daily stoma output as measured in millilitres per day and recorded by participants on record sheets provided.
Timepoint [1] 289710 0
The outcome will be measured at 2 time points. Measurements will be self recorded by patients on a record sheet provided which will be sent back to researchers in reply paid envelopes after the 5 days of intervention and again after the 5 days of control.
Secondary outcome [1] 303070 0
Mean frequency of stoma bag changes per day. The daily number of stoma bag changes will be self recorded by patients on a record sheet provided which will be sent back to researchers in reply paid envelopes after the 5 days of intervention and again after the 5 days of control to determine the mean frequency of stoma bag changes per day.
Timepoint [1] 303070 0
After 5 days of intervention and after 5 days of control

Statistical methods / analysis
Power calculation: The mean output from an established ileostomy is 465ml (S.D 219). We regard a clinically relevant reduction in output to be 150ml.
For an alpha level of 0.05 and beta of 0.1, we would require 23 patients (calculated for paired samples). Calculation done using Medcalc (R) software.
We will aim to recruit 40 patients to account for drop out.

Student t-test will be used for statistical analysis.
