UNDER EMBARGO UNTIL OCTOBER 7, 2020, 12:01 AM ET Research Brief How Online Grocery Stores Support Consumer Nutrition Information Needs Kelly Olzenak, MPH, RD1; Simone French, PhD1; Nancy Sherwood, PhD1; Joseph P. Redden, PhD2; Lisa Harnack, DrPH, RD1 ABSTRACT Objective: To evaluate the availability of nutrition-related information and features on leading online gro- cery store Web sites. Methods: Twelve US grocery Web sites were assessed to determine (1) if Nutrition Facts panel or ingredi- ent statements were available for 26 food items; and (2) if options to filter or sort search results by nutrition- related food attributes were available. Results: Nutrition Facts panel and ingredient statement information were available for most foods for which this information is required on product packaging (85% of foods). Most stores offered the ability to filter food search results by a nutrition-related food attribute. The ability to sort search results by a nutrition attribute was not an option at any of the stores. Conclusions and Implications: Online grocery stores include a variety of nutrition-related features. However, the Nutrition Facts panel and ingredient statement information are not universally available for foods for which this information is required on product packaging. Key Words: Internet, food, consumer behavior, Internet shopping, nutrition labeling (J Nutr Educ Behav. 2020; 52:952−957.) Accepted July 18, 2020.
