The galactooligosaccharides (GOS) are bioactive carbohydrates present in human milk. GOS could incorporated in dairy products, such as yogurt, from enzymatic action of beta-galactosidase on the milk lactose. Its consumption changes the gut microbiota composition which release several metabolites that could improve calcium absorption (CaAbs) and bone health. We evaluated the prebiotic effect on CaAbs of a yogurt containing GOS during normal growth. Male weaning Wistar rats (n=10 per group) received during 30 days AIN´93-G control diet (CD) or diet based on the yogurt containing GOS (ED), and calcium (Ca) and protein according to AIN´93-G.
