Dietary fibre intake in eastern Croatia as determined by an enzymatic-gravimetric method in duplicated portions

The aim of this study was to estimate the intake of dietary fibre (DF) in an urban adult sample in eastern Croatia. Forty five people (28 women and 17 men) took part in the investigation based on duplicate diet study. An enzymatic-gravimetric method was used to determine the content of total, as well as soluble and insoluble DF in duplicated portions. The mean total dietary fibre (TDF) intake for all subjects was 30.0 g/day, which is quite adequate with regard to recommendations and intakes reported from other countries. A relationship of DF intake with certain physical and socio-economic parameters (age, body mass index, education level, income per household member) of those taking part was examined. TDF intake was also found to be significantly influenced by season in this group of people, as the mean intake for the summer period was 21% higher than the winter period.
