Bone Abstracts

Background: Observations in rodents suggest that osteocalcin (OC) participates in glucose metabolism. Data from human studies are inconclusive and it remains unclear whether OC is simply a marker of bone turnover (BTM) or if it also mediates interactions between the skeleton and glucose homeostasis. This study determined the responses of BTMs, including OC, to oral glucose tolerance test (OGTT) in obese and normal-weight subjects.Materials and methods: P...

Phosphorus intake in western countries is high due to abundant consumption of animal protein and also because of the expanding use of highly absorbable food additive phosphate (FAP) salts in food processing. P is essential for hydroxyapatite in bone, but short-term studies have shown that high P, especially FAP, intake has acute negative effects on bone metabolism. In this study, we investigated the associations between dietary P intake and bone turnover markers by using a cro...
