Treatment ID:TR001609
Treatment Summary:The 10 vegan participants continued to follow their usual diet as outpatients. All participants completed the Diet History Questionnaire II (DHQ II), a food frequency questionnaire developed by the Risk Factor Monitoring and Methods Branch of the National Cancer Institute. The vegan participants also completed three 24 hour diet recalls with a dietitian in the week prior to starting antibiotics. 20 omnivores were randomly assigned to receive an omnivore diet or EEN (Modulen® IBD) while residing in an inpatient research unit. The macronutrient composition of Modulen® is protein 36g, fat 47g, and carbohydrate 110g per 1000 Kcal. The two omnivore diets were engineered to have a similar composition to EEN. All the subjects consumed the menu A on day 11 and menu B on days 4 and 14. Diets for omnivores were constructed to provide the expected total calories required per day for the participant to maintain their current weight and were adjusted if there was weight gain or loss of more than 2.5 pounds. On days 6, 7, and 8, inpatients participants received vancomycin 500mg orally every 6 hours and neomycin 1000mg orally every 6 hours. On day 7, participants consumed 4L of polyethylene glycol (PEG) based bowel purgative (GoLytely®). Participants in the omnivore and EEN arms left the inpatient research unit only under the direct supervision of a research staff member. The vegan outpatients reported to the hospital twice on days 6,7 and 8 to receive antibiotics and to consume PEG on day 7.
