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 and lifestyle variables in relation to incidence of Parkinson’s disease in Greece
Identification of dietary and lifestyle variables associated with the development of Parkinson ’s disease ( PD ) may offer pathogenetic clues and prevention opportunities . In a population -based prospect i ve cohort study , 26,173 participants in the EPIC – Greece cohort had sociodemographic , anthropometric  ,  medical , dietary  and  lifestyle variables  ascertained at enrolment and periodically reassessed with follow-up contacts . Based on these data , subjects were screened as possible PD cases if they ( 1 ) reported either a medical diagnosis of PD or use of anti-PD drugs and ( 2 ) did not report preceding causes of secondary parkinsonism . For diagnostic validation , possible incident PD cases were assessed by a focused 3-item telephone question naire . Cox proportional hazards regression was used to evaluate associations between potential predictors and incident PD . The main multivariate model included gender , age , marital status , schooling years , farming occupation , smoking status , caffeinated coffee , body mass index , physical activity and energy intake . Additional models included all above variables plus one dietary item at a time . Incidence rate adjusted to the European population was 16.9 per 100,000 person-years . In multivariate models , incident PD exhibited strong positive association with consumption of milk , but not cheese or yoghurt . This finding may help narrow down the search for potential dairy product components with a facilitatory role in PD . Concerning other dietary components , inverse association was found between polyunsaturated fat intake and incident PD . Also , inverse association was found with tobacco smoking , in line with previous studies , but not with caffeine
