Researchers from the University of Minnesota (including WGC Scientific Advisor Len Marquart) observed students at 10 schools in Minnesota and 7 schools in Texas, to see whether whole grain pancakes and tortillas can readily be substituted for similar refined products. For the study, foods with varying percentages of whole grain content were used. Using both aggregate plate waste measurements and student taste ratings, the scientists noted no difference in whole grain vs. refined grain pancake consumption at both elementary and middle / high schools, while consumption of whole grain tortillas was lower than refined tortillas. In general, elementary students were pickier than middle and high school students, and the use of whole white wheat boosted acceptance over whole red wheat. The researchers concluded that products such as those in the study would increase consumption of whole grains among children and youth.
