Tagging food choices with zero to three stars based on how healthy the items are is making a difference at Hannaford Bros. supermarkets in New England. The chain reports that items with at least one star are outpacing sales of items with no stars. Hannaford is looking to patent the rating system, but in general, USA Today reports that "vitamins, minerals, fiber and whole grains earn more stars. Added sodium, trans fats, saturated fats and cholesterol mean fewer, or no, stars."

Customers like the system because it saves them time when comparing food choices and it helps simplify nutritional choices for young children. Many restaurants use a similar concept, marking heart-healthy, carb-conscious or low-cal meals with special symbols. And with all the news surrounding trans fats, obesity rates and junk food regulations, it might pay off for your business to provide customers with the information they need to make an informed nutrition decision.--Francine Kizner
