## What is Yllo?

Yllo is a food intolerance scanner for lactose, oxalate, histamine, low FODMAP and gluten. Scan a barcode and know in seconds whether a food fits your diet.

No more squinting at tiny ingredient lists: Yllo reads a product's barcode or label and checks it against YOUR intolerances, color-coded for your own sensitivities. Free, no account needed.

Lactose intolerance, histamine intolerance, gluten sensitivity, IBS, a low FODMAP diet or a low oxalate diet: Yllo turns confusing labels into a clear, visual answer.

WHAT YLLO DOES

- SCAN any barcode with your phone camera: a personal food scanner that covers US products too
- EXPLORE the food library without scanning: search any food, additive or E-number, filter by category and intolerance level, before you shop or plan meals
- COVER 12 intolerances: FODMAPs, lactose, histamine, gluten, fructose, oligosaccharides, sorbitol, sucrose, tyramine, salicylates, nickel, oxalates
- SEE each ingredient in green, yellow, orange or red for YOUR profile
- DECODE additives: an E-number checker that recognizes E202, E322, E500, E503… in any language, with their other names (e.g. "E322" = "lecithin", from soy or sunflower)
- VIEW Nutri-Score, NOVA group, Eco-Score, allergens, vegan status and nutrients per 100 g

FREE WELLNESS PATH

Beyond intolerances, the Wellness Path rates every product on four criteria: sugar, salt, ultra-processing (NOVA) and risky additives. Then, when you're ready, it helps you bring fiber back gradually.

SOURCED, NOT GUESSED

Every intolerance level in Yllo rests on published research: scientific studies, food composition tables and EU regulations. The full reference list is in the app.
