Abstract Groups of 15 male rats were fed ad libitum for 4 weeks with a standard diet containing 0, 2.5, 5.0 or 10.0% dietary fibre (DF) prepared from sugar beet. The highest food consumption was found in the group with 10% DF in the diet. Food efficiency was highest in the control group. Average body weight increased continuously in all groups without significant differences. Enrichment of the diet with the DF preparation did not substantially influence urinary parameters [pH, specific gravity, protein or activities of aspartate aminotransferase (ASAT), alanine aminopeptidase and alkaline phosphatase (AP)]. Haemoglobin concentration and haematocrit, mean corpuscular haemoglobin concentration and mean corpuscular volume as well as total numbers of erythrocytes, thrombocytes and leukocytes counts did not significantly differ between the groups. Lower counts of eosinophils and neutrophils were measured in rats fed DF-enriched diets. Serum parameters (urea-N, protein, glucose, triglycerides and activities of ASAT, alanine aminotransferase, AP and leucine aminopeptidase) did not differ between groups. As the amount of DF preparation in the diet increased, serum cholesterol was reduced in trend. Furthermore, no significant differences were found between the groups with respect to the organ weights of rats. In conclusion, important or critical dose-related differences in the determined parameters were not found. This sub-acute feeding study showed that no toxic effects were related to used doses of DF which was prepared from sugar beet.
