Abstract We surveyed shoppers in one cooperative food store and one commercial supermarket in each of three cities to determine whether shoppers' food intake differed according to the market in which they shopped. The cities were Corvallis, Oregon; Davis, California; and Ithaca, New York. Shoppers completed questionnaires indicating how often they consumed each of 28 foods. In all locations, co-op shoppers showed less frequent consumption of meat products and refined grain products but more frequent consumption of certain produce items and specialty foods such as tofu and alfalfa sprouts. These practices are in keeping with the orientation of the nutrition education programs usually found in this type of cooperative store.
