In an IOM report entitled School Meals: Building Blocks for Healthy Children, the institute said: "The Food and Drug Administration should take action to require labeling for the whole grain content of food." It went on to recommend that products with eight grams or more whole grain per serving should be designated ‘whole grain-rich products’, a level that the Whole Grains Stamp has been using since the program began in 2005.

Director of food and nutrition strategies for the non-profit Whole Grains Council Cynthia Harriman said: “At a time when front of pack labeling is under close scrutiny, it's clear that the Whole Grains Council chose a responsible, scientifically-grounded path with the Whole Grain Stamp.”
