SCARBOROUGH, Maine (AP) – A gold star rating system for nutrition has been revised for the first time since being launched three years ago by the Hannaford supermarket chain.

Guiding Stars shelf tags already reflect the tweaks, which include removing the penalty for small amounts of trans fat that appear naturally in some meat and dairy products.

Maine-based Hannaford says its data indicates consumers have been buying more of the higher-rated items since the debut of Guiding Stars in 2006. Since then, Guiding Stars has been spun off into a separate licensing company. It’s advised by a scientific panel.

Guiding Stars appear in more than 1,400 Food Lion, Hannaford and Sweetbay supermarkets from Maine to Florida. They’re also used at Bates College and a public school district in Maine.
