the nutrition iq program is a joint venture of the joslin clinic and the supermarket operator supervalu. the labeling system consists of color-coded tags denoting a food product's status. this is based on attributes such as vitamin and mineral content, fiber content, 100%-juice content, omega-3 or low saturated-fat content, whole-grain content, calcium content, protein content, low- or reduced-sodium content and low- or reduced-calorie content. the first phase of the program began in 2009, covering center-store food products; coverage of fresh-food departments followed in 2011.
