Hannaford's Chain concludes nutrition sells

The Hannaford Brothers grocery store chain, based in Maine, has developed a nutritional rating system to help guide customers towards healthier foods.  The system that Hannaford developed, called Guiding Stars, rated the nutritional value of the grocery items in the store on a scale of zero to three stars, with three representing the most nutritious products.  A survey of Hannaford customers found that 81% were aware of the system and half of the customers used it fairly often.
