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 .
Dairy Product, Saturated Fatty Acid, and Calcium Intake and Prostate Cancer in a Prospective Cohort of Japanese Men
Many epidemiologic studies have reported a positive association between dairy products and prostate cancer .  Calcium or saturated fatty acid in dairy products has been suspected as the causative agent . To investigate the association between dairy products , calcium , and saturated fatty acid and prostate cancer in Japan , where both the intake of these items and the incidence of prostate cancer are low , we conducted a population -based prospect i ve study in 43,435 Japanese men ages 45 to 74 years . Participants responded to a vali date d question naire that included 138 food items . During 7.5 years of follow-up , 329 men were newly diagnosed with prostate cancer .  Dairy products were associated with a dose-dependent increase in the risk of prostate cancer . The relative risks ( 95 % confidence intervals ) comparing the highest with the lowest quartiles of total dairy products , milk , and yogurt were 1.63 ( 1.14 - 2.32 ) , 1.53 ( 1.07 - 2.19 ) , and 1.52 ( 1.10 - 2.12 ) , respectively . A statistically significant increase in risk was observed for both calcium and saturated fatty acid , but the associations for these were attenuated after controlling for potential confounding factors . Some specific saturated fatty acids increased the risk of prostate cancer in a dose-dependent manner . Relative risks ( 95 % confidence intervals ) on comparison of the highest with the lowest quartiles of myristic acid and palmitic acid were 1.62 ( 1.15 - 2.29 ) and 1.53 ( 1.07 - 2.20 ) , respectively . In conclusion , our results suggest that the intake of dairy products may be associated with an increased risk of prostate cancer . ( Cancer Epidemiol Biomarkers Prev 2008;17(4):930–7
