If warning labels became mandatory, as public health advocates propose, the pressure on manufacturers would increase to change certain products to improve their nutritional quality.
This is the section of a food label consumers see first, which within seconds can influence their purchase. This has made it a battleground between public health advocates and food manufacturers. Food manufacturers can choose to display FOP symbols or graphics that highlight nutritional aspects of the product if they are favorable to health, such as being lower in calories or added sugar, but may leave out less favorable information such as being high in sodium or saturated fat. These graphics promote a perception of healthfulness, which can be misleading if consumers rely only on these images without reading the Nutrition Facts panel for complete information. The FDA does not closely monitor these FOP graphics. Because research has shown that “positive” FOP labels like health stamps or checkmarks can overrate a food’s healthfulness, public health advocates have supported initiatives for FOP “warning” labels (e.g., traffic lights or stop signs) to highlight nutrients that are harmful to health in excess, such as sugars and fats in sweetened beverages and ultra-processed snacks. All FOP labels in the U.S. are voluntary, which allows food manufacturers to highlight or hide the nutrition information they choose to help promote or preserve sales. If warning labels became mandatory, as public health advocates propose, the pressure on manufacturers would increase to change certain products to improve their nutritional quality.
