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 .
Does eating yogurt prevent antibiotic-associated diarrhoea? A placebo-controlled randomised controlled trial in general practice.
BACKGROUND Probiotic capsules have been shown to reduce the incidence of  antibiotic-associated diarrhoea  in a number of setting s. If probiotic yogurt were equally efficacious then it would provide a simple and cost-effective means of preventing antibiotic-associated diarrhoea . AIM To investigate whether eating live bio yogurt at the time of taking oral antibiotics can prevent antibiotic-associated diarrhoea . DESIGN OF STUDY This study was a three-arm ( bio yogurt , commercial yogurt , no yogurt ) r and omised controlled trial with double blinding between the two yogurt arms . SETTING A single primary care general practice surgery in Hingham , Norfolk . The study population included all ages except babies . METHOD Patients aged over 1 year who required a 1-week course of antibiotics were included in the study . There was complete follow up for 369 patients . The intervention was the consumption of 150 ml of live strawberry-flavoured yogurt for 12 days , starting on the first day of taking the antibiotic .  Diarrhoea was defined as ' three or more loose stools per day over at least 2 consecutive days ' within 12 days of starting the antibiotics . RESULTS Of the 120 patients in the no-yogurt group , 17 ( 14 % , 95 % confidence interval [ CI ] = 9.0 to 21.5 ) developed diarrhoea . Of the 118 given commercial yogurt , 13 ( 11 % , 95 % CI = 6.6 to 17.9 ) developed diarrhoea ; nine of the 131 patients ( 7 % ; 95 % CI = 3.7 to 12.5 ) given bio yogurt developed diarrhoea ( P = 0.17 ) . CONCLUSION Overall , this study failed to demonstrate that yogurt has any effect on antibiotic-associated diarrhoea
