An assessment of dietary intake, food avoidance and food beliefs in patients with ulcerative colitis of different disease status

ABSTRACT

Background/Aims@#Ulcerative colitis (UC) is a chronic, relapsing and remitting inflammation of the gastrointestinal tract. Little is known about the link between dietary intake, food avoidance, and beliefs among UC patients of different disease severity. Therefore, this study aimed to assess the dietary intake, food avoidance, and beliefs among active and inactive UC patients. @*Methods@#A cross-sectional study was conducted among UC patients from a tertiary medical center in Kuala Lumpur, Malaysia. Demographic, anthropometric, dietary intake, food avoidance and beliefs were assessed. Disease activity of UC patients was evaluated using the Powell Tuck Index. @*Results@#UC patients were recruited (64.1% inactive UC and 35.9% active UC). As compared to inactive UC patients, active UC patients were likely to lose weight (75.0% vs. 0%), possess certain food beliefs (95.7% vs. 39.0%), and frequently practiced dietary avoidance (95.7% vs. 43.9%). The dietary intake among inactive UC patients was higher than active UC patients. However, neither of them met the standard nutrients recommendation for protein, calcium, iron, folate, zinc, vitamin D, vitamin B12, and vitamin E. @*Conclusions@#Active UC patients had poorer dietary intake, were more prone to practicing food avoidance and exhibited certain food beliefs as compared to inactive UC patients. Both macro- and micronutrients intakes were inadequate regardless of patient’s disease status. These findings emphasized the importance for patients to be provided with the nutrition-related knowledge as part of strategies to avoid nutritional inadequacies.
