Clinical trials

The aim of the study is to validate short questionnaires for assessing dietary intake of selected food components, with a focus on dietary fibre and iron. Two internationally developed short questionnaires (FiberScreen \[for dietary fibre\] and IRONQ-FFQ \[for iron\]) were adapted to the Slovenian context and will be compared with the standard 24-hour dietary recall method.

single-center, randomized, cross over, double-blind, placebo controlled intervention study

The effects of different foods to normal bowel function in adult population will be investigated. A randomised controlled intervention trial will be conducted on about 120 (30 per group) adult (18-70 years) subjects with functional constipation and irritable bowel syndrome with constipation according to the IV. Rome criteria. At least one week before inclusion in the study, patients will stop taking laxatives and other anti-constipation medications. Subjects will be randomly selected to consume one of the test foods (fresh apples, dried apples, sauerkraut) or the active control (psyllium) in the equivalent amount of 3 g of fiber per day for 4 weeks. Subjects will be asked not to change their lifestyle habits, such as diet and physical activity level, and not to take oral laxatives during the period of participation in the study.
