19% of Flours at Supermarkets in Sydney are Whole Grain

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.

Whole Grains Linked with Lower Risk of Type 2 Diabetes

In a large study of nearly 200,000 US adults, those eating whole grains most frequently had a 29% lower risk of developing type 2 diabetes across the approximately 30-year study period than those rarely or never eating whole grains, even after adjusting for other lifestyle factors. When looking at specific whole grain foods, common foods like whole grain breakfast cereal, oatmeal, whole grain bread, and brown rice were all linked with a lower risk of type 2 diabetes. The exception was popcorn, which was linked with a higher risk of type 2 diabetes when eaten more than once per day, perhaps due to its association with butter sauces or sugary flavorings.
