Patients and methods: A total of 53 patients with irritable bowel syndrome was enrolled in a non-propabilistic sample. Patiens were diagnose with Roma II criteria. In all patients were determined, weight, height, body mass index, dietary intake of 3 days and a symptoms scoring system. Results: The average age of 53 patients was 45.67±13.6 years with a distribution of sex (22 males/31 females). Caloric intakes was righ in absolut terms and corrected by weight. Distribution of calories was 41.5% of carbohidrates, a 19.8% of proteins, and a 38.7% of lipids, showing a high intake of lipids and low of carbohidrates. A low intake of vitamin A and D was detected. High intake of vitamin B12, vitamin C and niacine was observed. A low intake of calcium, magnesium, yodo and zinc was detected. Intake of soluble fiber was lower than insoluble fiber (1.46±0.74 g/day) (19%) vs 6.21±2.67 g/day (71%). Intake of fiber corrected by calories was low 4.5±1.2 g/1000 calories. In correlation analysis, insoluble fiber (r=0.46; p < 0.05) and soluble fiber (r=0.42; p < 0.05) were inverse correlated with general symptoms. Conclusions: Patients with irritable bowel syndrome showed a desviation of mineral and vitamin dietary . Fiber intake is low, a correlation between fiber intake and general symptoms was detected.
