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 .
Yogurt Consumption Does Not Enhance Immune Function in Healthy Premenopausal Women
Fermented milk products may protect against  breast cancer  by stimulating immunologic activity . Twenty- five women [ 24.0 ± 0.7 ( SE ) yr ] were assigned r and omly to two groups : control ( n = 12 ) and  yogurt treatment ( n = 13 ) . Controls refrained from yogurt products for three months , whereas the yogurt treatment group consumed two cups ( 454 g/day ) of commercially produced yogurt for three consecutive months . Prior yogurt consumption did not exceed 4 - 6 cups/mo , and subjects consumed their usual diet during the study . Three-day diet records and fasting midluteal blood sample s were obtained during subjects ' first , second , and fourth menstrual cycles ( baseline , Month 1 , and Month 3 , respectively ) . Macronutrient intakes differed between groups only for carbohydrate . Calcium intake increased for yogurt consumers during intervention . Lymphocyte proliferation induced by concanavalin A , phytohemagglutinin , and pokeweed mitogen , interleukin 2 production , and cytotoxic T lymphocyte-mediated cytotoxicity was assessed after baseline and Months 1 and 3 for both groups . No significant immune differences between the control and yogurt treatment group were observed for concanavalin A , phytohemagglutinin , pokeweed mitogen , interleukin-2 , or cytotoxicity . In conclusion , three months of yogurt consumption did not enhance ex vivo cell-mediated immune function in young women
