Decoding a food label is its own little nightmare — a wall of additives and numbers most shoppers can’t parse. An app called Yuka collapses all of it into a single number. Scan a barcode and you get a health score from 0 to 100, color-coded from red “Bad” to dark-green “Excellent.” It’s simple, fast, and increasingly powerful.
How the score works
Each product’s score is built from three inputs: 60% from nutritional value, 30% from the presence of additives, and a 10% bonus if it’s organic. The verdict comes with a color — red (0-24), orange (25-49), light green (50-74) or dark green (75-100) — so the judgment lands in a glance, no nutrition degree required.
The scale
Yuka now serves more than 80 million users across 12 countries, and the United States is its biggest and fastest-growing market with around 22 million users. That reach is what turns a personal habit into market pressure: when tens of millions of people consult an app before they buy, the score starts to move sales.
It’s changing what’s on shelves
The behavior change is real. The app reports that 94% of U.S. users will put a product back if it scores “bad,” and 92% say they buy fewer ultra-processed foods since using it. Yuka also lets users message brands directly to ask them to drop a high-risk additive — pressure that’s working. Chobani, for one, removed an additive from its oat milk after such requests.
The caveat
Nutrition scientists urge a grain of salt. Compressing a complex food into one number involves judgment calls, the additive penalties can be debated, and a high score doesn’t make a food a health food (or a low one poison). Food makers also complain the system is opaque. Yuka is a useful nudge toward less ultra-processed eating — not a substitute for nutritional context or professional advice.
Why it matters
Ultra-processed food is at the center of a global health debate, and shoppers have long been outmatched by labels designed to confuse. By turning that label into an instant, AI-assisted verdict, Yuka shifts a little power back to the consumer — and, increasingly, reaches back up the supply chain to change what companies put in the box.
