Many dietary guidelines recommend that people make at least half their grains whole, yet little has been published on the availability of whole grain options at supermarkets. In a February 2020 audit of the ﬂour aisle at four major supermarkets in metropolitan Sydney, researchers identiﬁed 130 diﬀerent ﬂour products. Of those, only 19% were whole grain ﬂour. The majority of products were reﬁned wheat ﬂour. Not surprisingly, the whole grain ﬂours contained signiﬁcantly more ﬁber and protein.
