Digital food ordering usage through mobile applications is increasing at dramatic rates. These platforms may influence the ordering decisions of consumers, yet little is known about their impact on the diet quality of foods and beverages ordered. To compare the sales and nutrient composition of caffeinated beverages ordered using a mobile ordering application (app) versus a traditional walk-up ordering method. This was a cross-sectional study conducted over a one-month period at a southeastern university in Miami. Itemized-sales data were collected from the on-campus Starbucks outlet, for customers who ordered drinks either via a traditional walk-up method or an online ordering system using the app Tapingo. The average drink order per customer was analyzed and sales, calories, saturated fat, and sugar was compared between the Tapingo group and the non-Tapingo group. Independent t-tests were conducted using SPSS v.21.0. Over the month examined, Tapingo app sales were $14,427.91 for n = 3,451 drink orders. Non-Tapingo sales were $79,396.73 for n = 21,839 drink orders. Sale prices, calories, saturated fat and sugar were all standardized by number of drinks ordered per platform for comparison. Tapingo app orders were higher in price (t =-8.187, P <.001), calories (t = -2.98, P =.003), saturated fat (t = -1.99, P =.048) and sugar (t = -2.10, P =.036). These findings suggest that consumers who use mobile food ordering applications are more likely to order less nutrient dense options and caffeinated beverages higher in calories, saturated fat, and sugar compared to a consumer using the traditional walk-up ordering method. Future research should focus on understanding the health implications of online ordering, and nutrition education opportunities need to be provided for consumers using these platforms to help them make better food choices.
