Calcium (Ca) and vitamin D nutritional status effects on oral health were evaluated in 85 healthy women aged between 20 and 30 years (24.6±0.4). They attended the first year of the Nutrition Carrier at the Private University (ISALUD, Buenos Aires, Argentine). Usual Ca intake (CaI) was determined by a food-frequency questionnaire that included consumption of dairy products and calcium-enriched foods. Blood samples were obtained in a fasting state in winter: the end of Augu...

Dietary Ca insufficiency is a common finding, independently of socio-economic status. A low Ca intake (CaI) increases bone turnover leading to bone loss. This effect becomes more important during estrogen withdrawing. We previously found that a mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) enhances Ca and P absorption (Abs), being a suitable tool to optimize its bioavailability and consequently bone health. The present study evaluated the effect of ...

It has suggested that BGP is inversely related to body fat. BGP appears to regulate energetic metabolism through the insulin receptor signaling pathway in the osteoblast, which affects bone resorption and BGP activity. Fat tissue is an endocrine organ that secretes different hormones and growth factors; several of them affect bone remodeling and insulin secretion. The present report comparatively studied total BGP levels, glucose homeostasis and body fat mass in spontaneous ob...

A mixture of Galacto-oligosaccharides (GOS) and Fructooligosaccharides (FOS) are added to commercial infant formula to promote an intestinal microbiota similar to that prevalent in breast-fed infants to improve Ca bioavailability and general health, but their mechanisms are under debate.Our objective was to evaluate the beneficial effects of the mixture of GOS/FOS added to infant formulae, on the absorption of Ca, Mg and P of a low Ca diet. Changes in in...

During early life undernutrition impairs normal weight and height gain that affects bone health. During recovering it is required an extra-amount of Ca to ensure the high demands of bone mineralization. A mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS) would be a useful tool to increase mineral intestinal absorption to enhancing the amount of Ca to be retained into bone. Our objective was to evaluate, in an experimental model of protein restriction (P...
