Galactooligosaccharides (GOS), prebiotic nondigestible oligosaccharides derived from lactose, have the potential for improving mineral balance and bone properties. This study examined the dose-response effect of GOS supplementation on calcium and magnesium absorption, mineral retention, bone properties, and gut microbiota in growing rats. Seventy-five(More)
The aim of this study was to investigate whether a product rich in transgalactooligosaccharides (TOS, Elix'or) stimulates true Ca absorption in postmenopausal women. The study was a double-blind, randomized crossover study, consisting of two 9-d treatment periods separated by a 19-d washout period. During the treatment periods, 12 subjects drank 200 mL(More)
AIM To evaluate the ability of specific carbohydrates, including commercially available products, to support the growth of representatives of two well-known groups of gut commensals, namely lactobacilli and bifidobacteria. METHODS AND RESULTS Sixty-eight bacterial strains, representing 29 human-derived lactobacilli and 39 bifidobacteria (both human- and(More)
Galacto-oligosaccharides (GOS) are carbohydrates that are fermented by colonic microbiota. The present study examined effects of a 3-week dietary enrichment with 6 % (w/w) GOS on parameters of energy balance in forty-three male Wistar rats. GOS was tested with two doses of calcium phosphate (30 and 100 mmol/kg), known to differently affect colonic(More)
The effectiveness was examined of inactivity and weight loss as criteria to identify a frail subgroup within independently living elderly persons participating in the SENECA study (Survey in Europe on Nutrition and the Elderly, a Concerted Action). Eight-hundred-forty-nine participants (aged 75 to 80) from nine countries were classified in four subgroups:(More)
Necrotising enterocolitis (NEC) is one of the most frequent and fatal intestinal disorders in preterm infants and has very limited treatment options. Breast-fed infants are at a 6-10-fold lower NEC risk than formula-fed infants, and we have previously shown that human milk oligosaccharides (HMO) improved survival and reduced pathology in a rat NEC model.(More)
Prebiotics are considered to have potential to reduce disturbances in the gut microbiota induced by antibiotics. Results in literature are, however, not consistent. The current in vitro study conducted in a fermentation screening platform allowed to unambiguously compare the impact of galacto-oligosaccharides (GOS) on adult gut microbiota composition and(More)
BACKGROUND The integrity of the epithelial layer in the gastrointestinal tract protects organisms from exposure to luminal antigens, which are considered the primary cause of chronic intestinal inflammation and allergic responses. The common wheat-associated fungal toxin deoxynivalenol acts as a specific disruptor of the intestinal tight junction network(More)
Adolescence is a time for rapid growth that represents an opportunity to influence peak bone mass. Prebiotic agents, such as galacto-oligosaccharides (GOS), increase Ca absorption in animal models and postmenopausal women. The objectives of the present study were to investigate the dose-response relationship of GOS supplementation on Ca absorption during(More)
Human milk is a rich source of oligosaccharides. Acidic oligosaccharides, such as sialyllactose (SL), contain sialic acid (SA) residues. In human milk, approximately 73% of SA is bound to oligosaccharides, whereas only 3% is present in free form. Oligosaccharides are highly resistant to hydrolysis in the gastrointestinal tract. Only a small portion of the(More)
