Adequacy of nutritional intake in a Canadian population of patients with Crohn's disease

Crohn's disease is frequently associated with nutritional deficiencies, often a result of disease activity and poor oral intake. This study investigated the adequacy of dietary intake, based on the Canadian Dietary Reference Intake, in ambulatory patients with Crohn's disease and a normal body mass index (BMI; calculated as kg/m(2)). This was a cross-sectional study of 74 patients with mean age of 35.7 +/- 1.4 years and BMI of 23.05 +/- 0.45. All patients completed a 7-day food record and a diary for the Crohn's Disease Activity Index. Mean Crohn's Disease Activity Index was 138.99 +/- 11.38. Energy and protein intakes were within the recommended levels of intake, but total carbohydrates, fat, and saturated fat intake exceeded the recommended levels of < 55%, < 35%, and < 10% in 39.2%, 27%, and 59.5% of the patients, respectively. Micronutrient intakes were suboptimal most notably for folate, vitamins C, E, and calcium. There were no substantial differences between patients with active and inactive disease in terms of failure to meet the Dietary Reference Intake. In conclusion, in this population sample, a large number of ambulatory patients with Crohn's disease have suboptimal dietary patterns despite a normal BMI and inactive disease. Dietary counseling and supplementation may be warranted in this patient population.
