Effects of a high fat diet on bone of growing rats. Correlations between visceral fat, adiponectin and bone mass density

In this study, we investigated some bone parameters ( bone mineral content, bone mineral density, skeleton area) in growing rats fed with a high fat diet. Correlations between bone and body composition parameters are reported. Two groups of Wistar male rats ( 35 days old, body mass 80 +/- 6 g) were used. Water and food were given "ad libitum" during 10 weeks. Sixteen rats ( L) were given a lipid enriched diet and were compared to 16 rats ( S) fed with a standard diet. Body composition and bone parameters were assessed using DXA. Results indicated that L rats had lower body mass, lean body mass; fat mass was not different between the two groups. Bone mineral content, bone mineral density, skeleton area of L rats were lower compared with S rats. Significant correlations were noted between body composition, adiponectin and bone parameters. High fat diet intake during the growing period has deleterious effects on bone parameters in rats. This study confirms in growing rats that a high fat diet is pathogenic, including bone metabolism.
