When provided information about the nutritional content of supermarket foods, more consumers will choose healthier items.
That’s the finding of a new study that investigated Hannaford Supermarkets’ gold star food rating system. The study, whose results were published in Food Policy, compared data from 134 Hannaford stores in Northeastern states against a control group of non-Hannaford supermarkets that did not have a food rating system, the Associated Press notes.
Researchers found that sales of cereals that received a no-star rating were 2.58% lower at Hannaford stores. Cereals with a higher star rating saw modestly higher sales at Hannaford stores, compared to the control group.
Hannaford, a subsidiary of Delhaize Group (DEG), operates 1,800 stores across North America. It implemented its gold star system in 2006.
