AMERICANS CAN CORRECTLY CATEGORIZE MOST FOODS AS WHOLE GRAIN OR REFINED GRAIN
In this study, researchers asked 169 low-income adults to look at 11 foods in their original packaging and determine if each was a whole grain or a reﬁned grain. The majority of participants (7 out of 10) correctly identiﬁed 4 out of 5 of the whole grain products as whole grain, and nearly as many (6 out of 10) participants correctly identiﬁed 5 out of the 6 reﬁned grain products. Speciﬁcally, 9/10 people correctly identiﬁed whole grain bread, 8/10 correctly identiﬁed whole grain crackers & whole grain cereal, and 7/10 correctly identiﬁed oatmeal as a whole grain, while popcorn tripped most people up (with only 3/10 people correctly identifying it as a whole grain food). Similarly, 8/10 correctly identiﬁed reﬁned crackers, 7/10 correctly identiﬁed reﬁned macaroni and tortillas, and 6/10 correctly identiﬁed reﬁned bread and cereal, while white rice was tricky for people (with only 4/10 correctly identifying it as a reﬁned grain). Based on interviews with a subset of 60 of the participants, the researchers found that helping people more clearly identify whole grains on the package, and reducing the cost (or perceived cost) of whole grain foods may help increase whole grain consumption in low-income adults.
