To make shopping for healthy foods easier, Walmart is unveiling their "Great for You" sticker this spring.
Marion Nestle applauded Walmart's strict standards for labeling the food. Labels will only go on one-fifth of the food carried at the super store, including fresh fruits and vegetables.
However, Nestle argued the stickers were not usually about improving health but pushing products.
Walmart's standards are in line with the USDA, the U.S. Department of Agriculture and the Institute of Medicine.
