A food scanner for spotting hidden sugar

Sugar hides under dozens of names and turns up in food that does not taste sweet. Yuzu makes it a barcode scan: spot the hidden sugar, and see it priced into the score, so you can compare products quickly. This is a general food scanner, not medical advice.

Not medical advice. Yuzu is not a medical device and cannot manage diabetes for you. It does not count carbs for insulin dosing or replace blood-glucose monitoring. Talk to your doctor or dietitian about your own targets.

How the sugar checker works

Scan a barcode and Yuzu reads the ingredients and nutrition. Sugar feeds into a 0–100 health score alongside salt and saturated fat, so a high-sugar product scores lower. Sugar that hides under other names, such as glucose-fructose syrup, dextrose or maltose, still appears in the ingredient list in plain English, so it is harder to slip past you.

Why sugar is not flagged like a chemical

Yuzu deliberately keeps additive risk separate from bulk-nutrient quantity. Sugar is a quantity question, so it is priced through the nutrition part of the score by how much is in the product, rather than getting a hazardous-chemical warning. A gram of sugar in a yoghurt and a gram in a cola are the same molecule; what matters is how much. How Yuzu works.

Frequently asked questions

Is there a sugar checker app for diabetics?
Yuzu Health scans a barcode and helps you spot sugar in a product, including the many names it hides under, and prices it into a 0–100 health score. It is a general food scanner, not a medical device, so use it to compare products and talk to your doctor about your own targets.
How does the sugar checker work?
Scan the barcode. Yuzu reads the ingredients and nutrition, then reflects sugar in the score alongside salt and saturated fat. Sugar going by other names, such as glucose-fructose syrup, dextrose or maltose, still shows up in the ingredient list in plain English, so it is harder to miss.
Is this app medical advice for diabetes?
No. Yuzu is not medical advice and not a substitute for your doctor, dietitian or blood-glucose monitoring. It does not count carbs for insulin dosing or set personal targets. It helps you see and compare the sugar in products. Always talk to your healthcare team about managing diabetes.
Does it flag sugar as dangerous?
No, and that is deliberate. Yuzu keeps additive risk separate from bulk-nutrient quantity. Sugar is a quantity question, not a hazardous chemical, so it is priced through the nutrition part of the score by how much is there, rather than getting a scary red chemical warning. High sugar simply pulls the score down.
Is the sugar scanner free?
Yuzu is free to download and scan, with a subscription for unlimited scanning. You can start checking products for sugar without paying.
