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 .
Calcium, vitamin D and dairy intake in relation to type 2 diabetes risk in a Japanese cohort
Aims /hypothesisCalcium and vitamin D have been implicated in the development of type 2 diabetes , but epidemiological evidence is limited . We examined prospect ively the relation of calcium and vitamin D intake to type 2 diabetes risk in a Japanese cohort . Methods Participants were 59,796 middle-aged and older men and women , who participated in the Japan Public Health Center-based Prospect i ve Study and had no history of type 2 diabetes or other serious diseases .  Dietary intake of calcium and vitamin D  were estimated using a vali date d food frequency question naire . Logistic regression was used to assess the association between intake of these nutrients and self-reported newly diagnosed type 2 diabetes . Results During a 5 year follow-up , 1,114 cases of type 2 diabetes were documented . Overall , calcium intake was not associated with a significantly lower risk of type 2 diabetes ; the multivariable odds ratio for the highest vs lowest quartiles was 0.93 ( 95 % CI 0.71–1.22 ) in men and 0.76 ( 95 % CI 0.56–1.03 ) in women . However , among participants with a higher vitamin D  intake  , calcium intake was inversely associated with diabetes risk ; the odds ratio for the highest vs lowest intake categories was 0.62 ( 95 % CI 0.41–0.94 ) in men and 0.59 ( 95 % CI 0.38–0.91 ) in women . Dairy food intake was significantly associated with a lower risk of type 2 diabetes in women only . Conclusions /interpretationCalcium and vitamin D may not be independently associated with type 2 diabetes risk . Our finding suggesting a joint action of these nutrients against type 2 diabetes warrants further investigation
