Whole Foods emerged as a health-food store almost 30 years ago. Today, the chain is as synonymous with luxury chocolate truffles as it is with organic produce, a problem that will soon be solved, according to CEO and co-founder John Mackey. This week, Mackey announced that next year Whole Foods will be the first grocery chain to provide nutrient-density labeling on products, providing consumers with nutrient-per-volume information. Mackey also emphasized the overall image and mission of Whole Foods will change from high-end indulgence to health. The company will focus on healthy eating and education by organizing classes, books, and supper clubs.
