Is Yuka Accurate for Food? How Its Score Is Built

Yuka says it cannot guarantee absolute accuracy: its scores are only as reliable as the product data behind them. Its help center describes its food score as three weighted parts: nutrition at 60% (calculated with Nutri-Score), additives at 30%, and an organic bonus at 10%. Yuka also says it does not claim to be a public health authority and that the app does not replace the information on product packaging. This guide lays out how the score is built, where the data comes from, and what Yuka itself says its limits are.

Key takeaways

• Yuka's food score has three weighted parts: nutrition at 60% (via Nutri-Score), additives at 30%, and an organic bonus at 10%.
• A high-risk additive sets the maximum food score at 49/100.
• Yuka's help center says its database grows through user contributions and brand-supplied data, after an early reliance on Open Food Facts.
• Yuka does not rate products with no nutritional values, which covers many single-ingredient, unprocessed, and non-prepackaged foods.
• Yuka states it cannot guarantee absolute accuracy and that its scores do not replace packaging information.

Is Yuka accurate for food? Yuka says its scores are only as reliable as its packaging data

Yuka says it cannot guarantee absolute accuracy, because its food scores depend on the product data it holds. That data is built from label information, user contributions, and brand submissions, so an outdated entry can produce an outdated score.

Yuka's limitations page says it 'strives to provide the most reliable data possible but cannot guarantee absolute accuracy.' It names one common failure mode: errors may occur 'particularly if a product's composition changes and has not been updated.' A reformulated product can keep an older score until its entry is corrected.

Yuka's help pages do not cite an independent validation study of its food scores, so the accuracy answer here rests on Yuka's own documentation.

How does Yuka score food? The 60% nutrition, 30% additive, and 10% organic split

Yuka's food score is a weighted total of three parts: nutritional quality at 60%, additives at 30%, and an organic bonus at 10%. The weights are stated on Yuka's help page for food scoring.

The nutrition part is calculated with Nutri-Score. The additive part assigns each additive a color from risk-free to high-risk. The organic part adds credit when a product carries an official organic label.

Because the additive section can cap the total, the three parts do not simply average out. A strong nutrition profile does not cancel a high-risk additive under Yuka's stated rules.

What does the Nutri-Score part of Yuka's food score measure?

The Nutri-Score part measures nutritional quality, which Yuka says is 60% of the food score. Yuka describes Nutri-Score as 'a science-based nutrition label adopted by 7 European countries.'

According to Yuka, the system accounts for sugar, sodium, saturated fat, calories, protein, fiber, and fruit and vegetable content. Yuka's page does not say whether it uses the original or the updated Nutri-Score algorithm, so that detail is not disclosed here.

Nutri-Score is a European system, not a US label. The US Nutrition Facts panel lists nutrients per serving, and the FDA describes 5% Daily Value or less as low and 20% Daily Value or more as high for a nutrient. The FDA's front-of-package page describes a proposed 'Nutrition Info box' that would show saturated fat, sodium, and added sugar. That is a proposed rule, not a final requirement.

How does Yuka's additive penalty work, and why can one additive cap a score at 49/100?

Additives make up 30% of Yuka's food score, and one high-risk additive caps the whole product at 49/100. Yuka assigns each additive one of four colors: risk-free (green), limited (yellow), moderate (orange), or high-risk (red).

Yuka's help page states: 'If an additive we consider to be high-risk is present, the maximum score for the product is set at 49/100.' The cap applies to the product total, not only to the additive section.

Yuka's scoring page does not publish its per-additive risk list or the sources behind individual additive ratings. This article cannot tell you which color a specific additive receives, so check the ingredient list on the package and the app's breakdown for each item.

What does the 10% organic bonus add to a Yuka food score?

The organic dimension is 10% of the food score and works as a bonus for products with an official organic label. Yuka's help page describes it as a bonus, not as a separate penalty for products without the label.

The bonus applies only when the package carries an official organic certification. A product without that label does not receive the 10% credit, so label wording matters when you compare two items.

Where does Yuka's food data come from, given the Open Food Facts and own-database history?

Yuka says it 'relied on Open Food Facts' at first, then created its own database in January 2018. That database grows through user contributions and brands that give direct access to product data.

Yuka's App Store listing says the database 'contains 4 million food products and 2 million cosmetic products.'

Other apps score the same label with different methods; see Yuka vs Fooducate: 0-100 Score vs A-D Grade and Yuka vs EWG App: How Each One Rates Your Food for side-by-side method comparisons.

How does Yuka verify label data, and when does it refuse to rate a product?

Yuka's verification page says it uses automatic image and text recognition, and that a team reviews contributions. Users can edit product pages, except pages verified by the team or supplied by brands.

If a label photo has 'more than 20% of text not recognized as ingredients,' Yuka says the list is manually transcribed by an external service. The product is not rated in the meantime.

Yuka also says it 'cannot guarantee the absolute reliability of the data.' Verification reduces errors but does not remove the need to check the package.

Which foods does Yuka not rate because nutrition labeling is not mandatory?

Yuka cannot rate products with no nutritional values, and many foods without mandatory nutrition labeling fall into that group. Yuka's help page lists the following examples:

• Single-ingredient unprocessed products
• Herbs and spices
• Coffees and teas
• Vinegars, flavorings, and yeasts
• Non-prepackaged items such as fruits, vegetables, cheese, and deli meats

Yuka's page does not describe another rating method for these items. Check whether a Nutrition Facts panel is printed before you expect a score. For a broader view of how one-number ratings handle this, see Myth: One Health Score Tells You If a Food Is Good for You.

What limits does Yuka state about its own food scores and medical advice?

Yuka states that it does not claim to be a public health authority, that it takes a precautionary approach, and that it does not provide medical advice. It also says its app 'does not replace the information on product packaging.'

Yuka also says errors may occur when a recipe changes and the entry is not updated.

The evidence available here cannot establish how well Yuka scores match health outcomes for any individual, for children, for pregnant people, or for people managing medical conditions. Questions about allergies, medications, or specific conditions belong with a qualified clinician.

How much does Yuka cost, and what does Premium change for food shoppers?

Yuka's app is free to download, with in-app purchases, and its Premium tier starts at $15/year with what Yuka describes as open pricing and no commitment. Yuka's pages do not disclose Premium prices in other currencies or the exact price tiers.

Free features include food analysis, cosmetic analysis, recommendations for poorly scored items, and scan history. Premium adds offline mode, search, food-preference alerts such as palm oil, gluten, and vegetarian, and unlimited history.

Yuka says its app is ad-free and that 'brands cannot pay Yuka to advertise their products.' It also says its revenue comes 'from users, never from brands.'
