摘要
In meta-analyses of prospective studies,high whole grain(WG)intake has been acknowledged for its potential role in lowering risk of type 2 diabetes,cancer,cardiovascular disease and all cause mortality(1,2).Unlike Refined wheat(RW)flours from which the bran and germ of the wheat kernel have been removed,whole-grain wheat(WGW)products retain these elements and are rich sources not only of dietary fiber,but also of betaine,choline,important minerals and vitamins,components with antioxidant properties,and other phytochemicals(3).They are thus considered nutritionally superior but previous WG interventions in human subjects have reported conflicting results in improvements in health parameters.
