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 Dairy Products and Cancer Risks
BACKGROUND Relationships between consumption of dairy products and death from various types of cancer are largely unknown . METHODS Between April 1992 and July 1995 , a baseline survey was conducted for 11,349 residents in 12 communities in Japan , which included collection of demographic data and a self-administered food-frequency question naire inquiring about three dairy products : milk , butter and yogurt . The subjects were followed prospect ively until 2002 . Causes of death were identified using death certificates . Hazard ratios ( HRs ) and their 95 % confidence intervals ( CIs ) for each dairy product were calculated using Cox s proportional hazard models . RESULTS Among eight common cancers , only deaths from hematopoietic neoplasm ( n=14 ) were significantly associated with consumption of butter ( HR=5.11 , 95 % Cl : 1.40 - 18.62 ) , though they exhibited a nearly-significant association with  milk  consumption ( HR=3.17 , 95 % Cl : 0.99 - 10.17 ) , independent of age and sex . Consumption of milk and butter was significantly associated with non-lymphoma deaths ( n=9 ) when adjusted for age and sex ( HR=9.86 , 95 % Cl : 1.23 - 79.19 for milk : and HR=10.04 , 95 % Cl 2.39 - 42.18 for butter ) . CONCLUSION The frequencies of butter consumption , and probably that of milk , were correlated with death from hematopoietic neoplasm , particularly from non-lymphomas
