New England grocery chain Hannaford Brothers has developed a system called Guiding Stars that rates the nutritional value of nearly all the food and drinks at its stores from zero to three stars.

Of the 27,000 products plugged into Hannaford’s formula since September, 77% received no stars, including many, if not most, of the processed foods that advertise themselves as good for you.

These included V8 vegetable juice, because of its sodium content and nearly all yogurt with fruit, because of its sugar. Whole milk got no stars, too, due to its fat. Most fruits and vegetables did earn three stars, as did things like salmon and Post Grape-Nuts cereal.

The company says that even no-star items have a place in a balanced diet, and that the consumers should read the system as good-better-best
