Tracking your food purchases can significantly improve health, as demonstrated by the rising popularity of the Yuka app. Launched in 2015, Yuka has gained 85 million users across 12 countries, including 28 million in the United States alone. This trend was highlighted by technology reporter John Laurenson on July 14, 2026, as consumers increasingly seek healthier shopping options.
How the Yuka App Works
The Yuka app allows users to scan barcodes of over six million products to receive immediate health ratings. Products are scored using a traffic light system: green for healthy, yellow for moderate, and red for unhealthy. Users can also access detailed information on additives, which often indicate ultra-processed foods.
Nathalie, a Parisian mother, illustrates this experience as she evaluates her son Malo's favorite biscuits. While she finds alternatives that are organic and nutritious, she notes, "You end up buying a lot more organic stuff so it’s more expensive." This reflects a common sentiment among Yuka users who prioritize health but face higher costs.
The Impact of Food Tracking on Consumer Behavior
Yuka's success is part of a broader food-tracking movement in France. In 2012, Stéphane Gigandet launched Open Food Facts, a crowdsourced database providing information on over four million food products. Additionally, the French government introduced the Nutri-Score labeling system, which offers a simple scoring method for food items.
According to Serge Hercberg, the creator of Nutri-Score, the system provides a straightforward way for consumers to assess food quality. He stated, "The Nutri-Score gives a global score. You can tell at a glance whether a product is going to be good or bad for your health." This simplicity has encouraged many manufacturers, including Danone and Nestlé, to adopt the label.
