For studies of a similar design and which assessed the same outcomes in similar population groups , we report the potential for the combining of data across studies in systematic review s. CONCLUSIONS This scoping review has revealed the extensive evidence base for many outcomes which could be the focus of systematic review s exploring the health effects of conventional yogurt consumption
BACKGROUND The health effects of conventional yogurt have been investigated for over a century ; however , few systematic review s have been conducted to assess the extent of the health benefits of yogurt .
OBJECTIVE The aim of this scoping review was to assess the volume of available evidence on the health effects of conventional yogurt .
Consumption of yogurts fortified in vitamin D and calcium reduces serum parathyroid hormone and markers of bone resorption: a double-blind randomized controlled trial in institutionalized elderly women.
CONTEXT Nutritional prevention of bone deterioration with fortified foods seems particularly suitable in institutionalized elderly women at risk of vitamin D deficiency , secondary hyperparathyroidism , increased bone resorption , and osteoporotic fracture . OBJECTIVE The objective was to evaluate whether fortification of yogurts with vitamin D and calcium exerts an additional lowering effect on serum PTH and bone resorption markers as compared with isocaloric and isoprotein dairy products in elderly women . DESIGN A r and omized double-blind controlled-trial , 56-day intervention was conducted in institutionalized women ( mean age 85.5 years ) consuming 2 125-g servings of either vitamin D- and calcium-fortified yogurt ( FY ) at supplemental levels of 10 μg/d vitamin D₃ and 800 mg/d calcium or nonfortified control yogurt ( CY ) providing 280 mg/d calcium . MAIN OUTCOMES The endpoints were serum changes from baseline ( day 0 ) to day 28 and day 56 in 25-hydroxyvitamin-D ( 25OHD ) , PTH , and bone resorption markers tartrate-resistant acid phosphatase isoform-5b ( TRAP5b ) , the primary outcome , and carboxyl-terminal cross-linked telopeptide of type I collagen ( CTX ) . RESULTS At day 56 , serum 25OHD increased ( mean ± SEM ) by 25.3 ± 1.8 vs 5.2 ± 2.5 nmol/L in FY ( n = 29 ) and CY ( n = 27 ) , respectively ( P < .0001 ) . The corresponding changes in PTH were -28.6 % ± 7.2 % vs -8.0 % ± 4.3 % ( P = .0003 ) ; in TRAP5b , -21.9 % ± 4.3 % vs 3.0 % ± 3.2 % ( P < .0001 ) ; and in CTX , -11.0 % ± 9.7 % vs -3.0 % ± 4.1 % ( P = .0146 ) , in FY and CY , respectively . At day 28 , these differences were less pronounced but already significant for 25OHD , PTH , and TRAP5b . CONCLUSIONS This study in institutionalized elderly at high risk for osteoporotic fracture suggests that fortification of dairy products with vitamin D₃ and calcium provides a greater prevention of accelerated bone resorption as compared with nonfortified equivalent foods
