Fortified yogurt with vitamin D as a cost-effective food to prevent diabetes: A randomized double-blind clinical trial

This study was conducted on 90 subjects with pre-diabetes in three groups: those given fortified yogurt with vitamin D, those given plain yogurt and those given oral vitamin D supplements. The study variables were evaluated at the beginning and end of the intervention period. Results from the participants’ oral glucose tolerance tests (OGTT) decreased significantly in only the fortified-yogurt group. The mean fasting serum insulin and the insulin-resistance index (HOMA-IR) in the fortified-yogurt (p < .01) and oral-supplement (p < .03, p < .04) groups decreased significantly. Waist-to-hip ratio (WHR) and percentage of body fat (PBF) decreased significantly in the fortified-yogurt (p < .02, p < .006) and oral-supplement (p = .015, p < .001) groups. These findings show that yogurt fortified with vitamin D improves glycemic and anthropometric indices in pre-diabetic individuals. Graphical abstract
