- The objective of the study was to evaluate the intestinal tolerance of a newly developed food containing Lactobacillus plantarum 299v, in children. The effects of consumption of the product on the children's nutrient intake were also followed, in a separate study. The tolerance study was parallel, double-blind, and included 69 children between 6 months and 3 years of age, randomized into two groups. One of the groups consumed a fermented oat product (1×109 cfu L. plantarum 299v/g) for 3 weeks, while the other group consumed a placebo product. We analysed the subjects by intention to treat and also carried out an analysis of subjects who had a mean intake of >100 g study product per day. After consumption for 3 weeks, the content of L. plantarum 299v in faeces increased significantly in the test group compared with the placebo group (p<0.001) and mean log10 cfu/g was 8.7 (intention to treat analysis). Also, the total content of lactobacilli increased and was significantly higher compared with the placebo group (p<0.001). The same result was also obtained when the data for the subjects who had a higher consumption of the study products were analysed. There were no differences in reported gastrointestinal function between the groups. The effects of the fermented oat product on the children's nutrient intake were followed in 12 children aged 1-3 years. Inclusion of the fermented oat product that was enriched with iron and ascorbic acid led to a significantly higher intake of several nutrients like energy, carbohydrates (g, E%), dietary fibre, iron and zinc. In conclusion, the children tolerated the fermented oat product well, the faecal microflora was positively altered and the children's nutritional intake was improved. Keywords: children, microflora, Lactobacillus plantarum 299v, probiotic bacteria, intestinal tolerance, nutrient intake.

- To study the role of selenium compounds for the quality and nutritional value of meat, speciation of selenium compounds was performed in two muscles from each of seven animal species (chicken, turkey, duck, ostrich, lamb, cattle and pig). Soluble selenium compounds were separated by size-exclusion chromatography (SEC) and detected by inductively coupled plasma-mass spectrometry (ICP-MS). Four selenium peaks were found in the muscle extracts by SEC, with partition coefficients (K-av) of 0.02, 0.44, 0.74 and 0.86, respectively. The second and third peaks had a chromatographic mobility approximately corresponding to that of tetrameric glutathione peroxidase and selenoprotein W, respectively, and they contained 68-100% of the recovered selenium in different muscles. The distribution of selenium among the four peaks varied considerably in muscles from different species, the second peak accounting for 28-71% of the recovered selenium and the third peak for 17-72%. These differences in selenium distribution among animal species are discussed in relation to meat quality and nutritional value.

- The aim of the study was to investigate whether a supplement of antioxidants to subjects with a high working pace can influence the antioxidant capacity. The study was parallel and double blind with 98 subjects randomised into two groups. One of the groups was given a test drink with antioxidants for 4 weeks (450 ml/day) while the other group took a corresponding amount of placebo drink. The test drink contained: 2 mg beta-carotene/100 ml, 40 mg alpha-tocopherol/100 ml, 80 mg ascorbic acid/100 ml, 2 mg pyridoxine/100 ml, 15 mg magnesium/100 ml, 0.2 mg manganese/100 ml, 1 mg zinc/100 ml, 0.1 mg copper/100 ml and 10 μg selenium/100 ml. Consumption of the test drink for 4 weeks increased the total plasma antioxidant capacity by 7% (ferric reducing ability of plasma method, P<0.05 compared with the placebo group), and the content of selenium and selenoprotein P in serum was raised by 16-17% (P<0.001 compared with the placebo group). No significant changes were found in the placebo group. The test drink also contained Lactobacillus plantarum 299v (5×107 cfu/ml) and 4 weeks' consumption led to a significant increase of Lb. plantarum 299v in the faeces. In conclusion, consumption of a drink rich in different antioxidants can increase the antioxidant capacity in subjects with a high working pace. This can be valuable since it may increase the protection against reactive oxygen radicals.
