Diet in Crohn's disease two studies of current and previous habits in newly diagnosed patients.

Abstract

The consumption of sugar and sugar-containing foods in 32 patients with recently diagnosed Crohn's disease was significantly greater than in matched controls; the assessment was made by a questionnaire and depended upon patients recalling their eating habits. In a further study of 16 patients with Crohn's disease, all food eaten over 5 days was weighed and recorded, and no significant difference was found in the consumption of carbohydrate, protein, fats, or sugars, although the consumption of "added sugars" in patients was greater than controls. Patients who participated in both studies significantly reduced their intake of added sugar, and this was not found to correlate with either total intake of monosaccharides and disaccharides or the total carbohydrate consumption. The increased consumption of added sugar in patients with Crohn's disease does not appear to be related to other dietary abnormalities and may simply reflect a deficiency in perception of sweet taste in patients with this condition.
