BOSTON — This year the Whole Grains Council is offering a kit designed specifically for retailers to help them promote whole grain products throughout the store during Whole Grains Month this September, or at any other time of the year, officials said. The kit, which includes in-store signage, handouts, an aisle-by-aisle shopping list, ideas for sampling whole grains, a recipe pack and a PowerPoint presentation, can be downloaded by retailers from the Council's website, wholegrainscouncil.org, by clicking on the Resources section. Retailers also can request that the materials be sent to them on a CD. The Whole Grains Council first proclaimed September to be Whole Grains Month last year. “We chose this time of year because it's both harvest and back-to-school time,” said Cynthia Harriman, the Council's director of food and nutrition strategies. By now, more than 2,000 packaged products carry the Whole Grains Council's stamp, and increasingly retailers are promoting fresh-made deli and bakery products that qualify to carry the identification. Similarly, in January the Whole Grains Council launched a menu symbol that has since helped more than 50 restaurant chains and independent eateries highlight whole grain options for their customers. The Store Tour Kit includes a new retailer logo that shows the Whole Grains stamp superimposed on a grocery cart.
