Food shoppers are becoming more vigilant about health-related aspects of food labeling, according to results of a survey released by the National Grocers Association and SupermarketGuru.com. The survey showed that 51% of food shoppers “almost always” look at the type of preservatives or additives, up nine percentage points from last year, and 43% “almost always” look at health claims, up seven points. SupermarketGuru also cited a survey, done in 2008 and recently released by the Food and Drug Administration, stating that 54% of consumers read the label of a product the first time they buy it (up from 10% in 2002), and of those, 66% “often” use the label to check for aspects like calories, salt and fat.
