BRAINTREE, MASS. — Price Chopper and Hy-Vee, two supermarket chains in the Northeast and Midwest, are now the first to feature the new NuVal Nutritional Scoring System. The NuVal system evaluates nutritional criteria and assigns products a number from 1 to 100 with higher numbers representing more nutritional products.

The NuVal Nutritional Scoring System was developed by Dr. David Katz of the Yale-Griffin Prevention Research Center along with a 12-member team of nutrition experts.

The NuVal numbers will be displayed on shelf tags at all 116 Price Chopper and 225 Hy-Vee stores, and more grocery chains will follow later this year.

"With NuVal, consumers can now receive reliable, easy-to-understand information on the food they buy at the best possible place and time — in the grocery aisle," Dr. Katz said. "These scores are based on the fundamentals of good nutrition and can be invaluable in eating healthier."

The idea is to be able to compare items side-by-side to determine what product offers better nutritional value.
