Current government-mandated nutrition labeling is ineffective in improving nutrition, but there is a better system available, according to a study by McGill University researchers published in the December issue of the Annals of the New York Academy of Sciences.
The researchers compared four different labeling systems and found that the Nutrition Facts label currently required on most food products in the US and Canada was least useable. That label, which lists the percent daily value of several nutrients, took more time to understand and led to nutrition choices hardly different from chance. Another label type, NuVal, enabled quick and nutritious choices. NuVal is a shelf sticker used in some American food markets, which indicates the overall nutritional value of each food item with a number from 1-100.
NuVal scores are calculated by nutrition experts at several universities, including Yale, Harvard, and Northwestern, and emphasize both the positive and negative aspects of each food. By reducing nutritional content to a single number, NuVal labels resolve nutrition conflicts.
