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 .
Milk, dairy products, and coronary heart disease
Milk has been considered a risk factor for atherosclerosis and coronary heart disease ( CHD ) because of its content in cholesterol , saturated fatty acids , and possibly lactose . However , epidemiological data are scanty and inconclusive . A Scottish prospect i ve study found a relative risk of 0.92 for  CHD  in men with higher milk intake  , and the preliminary analyses of the Caerphilly study found a protective association.1 No significant relation with CHD was found in other prospect i ve studies , including the British Regional Heart study conducted in men ( relative risk , RR , 0.88 for drinkers compared with non-drinkers),2 a British study on vegetarians ( increased risk in high milk consumers and reduced in moderate consumers),3 and the Iowa study in postmenopausal women ( RR 0.94 for the highest tertile of intake compared with the lowest),4 although absolute numbers of events were limited . An Italian case-control study of acute myocardial infa rct ion ( AMI ) in women found
