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 .
Dietary effect of lactoferrin-enriched fermented milk on skin surface lipid and clinical improvement of acne vulgaris.
OBJECTIVE Lactoferrin , a whey milk protein after removing precipitated casein , has a prominent activity against inflammation in vitro and systemic effects on various inflammatory diseases have been suggested . The objective was to determine dietary effects of lactoferrin-enriched fermented milk on patients with acne vulgaris , an inflammatory skin condition . METHODS Patients 18 to 30 y of age were r and omly assigned to ingest fermented milk with 200 mg of lactoferrin daily ( n = 18 , lactoferrin group ) or fermented milk only ( n = 18 , placebo group ) in a 12-wk , double-blind , placebo-controlled study . Acne lesion counts and grade were assessed at monthly visits . The condition of the skin by hydration , sebum and pH , and skin surface lipids was assessed at baseline and 12 wk . RESULTS Acne showed improvement in the lactoferrin group by significant decreases in inflammatory lesion count by 38.6 % , total lesion count by 23.1 % , and acne grade by 20.3 % compared with the placebo group at 12 wk . Furthermore , sebum content in the lactoferrin group was decreased by 31.1 % compared with the placebo group . The amount of total skin surface lipids decreased in both groups . However , of the major lipids , amounts of triacylglycerols and free fatty acids decreased in the lactoferrin group , whereas the amount of free fatty acids decreased only in the placebo group . The decreased amount of triacylglycerols in the lactoferrin group was significantly correlated with decreases in serum content , acne lesion counts , and acne grade . No alterations in skin hydration or pH were noted in either group . CONCLUSION Lactoferrin-enriched fermented milk ameliorates acne vulgaris with a selective decrease of triacylglycerols in skin surface lipids
