Yuka App Evaluate: Scan or Rip-off?


I’ve been requested many instances over the previous few years to do a assessment of the Yuka app. It’s at all times fascinating seeing apps that purport to assist individuals make higher selections with their meals, as a result of inevitably these apps cut back these selections to some arbitrary class of ‘good’ and ‘unhealthy.’

How does Yuka decide if a meals is ‘good’ or ‘unhealthy’? And what’s the profit or hurt of utilizing an app like this? Let’s get into it.

What’s the Yuka App?

The Yuka app was initially launched in France in 2017 and later launched in Canada and the US in 2022. In line with their web site, they’ve over 55 million customers. 

The app permits customers to scan barcodes of meals and beauty merchandise and provides them a ranking of how “wholesome” or not they’re. For merchandise with a decrease rating, the app suggests another option that they deem to be ‘higher’.

For this Yuka app assessment, we’ll persist with the meals and diet facet of the Yuka app.

If you scan a product, it provides you an total rating and ranking after which breaks down the optimistic and unfavorable attributes of a product primarily based on the Yuka app scoring system, which we are going to get to. 

The app additionally classifies meals as “good” or “unhealthy” primarily based on the general rating.

Yuka additionally prides itself on being impartial and never influenced by meals firms. There’s a premium, paid model of the app and that’s how they make cash.

How does the Yuka app rating merchandise?

The Yuka app scores merchandise primarily based on three elements: dietary high quality is 60% of the rating, the presence of components is 30%, and a product being natural or not is 10%. In line with the Yuka app’s web site, this 10% is a “bonus” that’s robotically given to natural merchandise. 

The scoring system for dietary high quality is predicated on a technique adopted by a number of European international locations referred to as Nutri-Rating. Nutri-Rating grades the dietary high quality of meals merchandise primarily based on power (energy), sugars, saturated fat, sodium, fibre, and protein and of fruit, greens, legumes and nuts. A front-of-package labeling system is then used, which breaks down meals into 5 classes primarily based on diet high quality. The system charges meals from ategory A to E, the place A signifies larger dietary high quality and E is decrease.

The classes are given a colour primarily based on a site visitors mild, the place the upper classes are inexperienced, descending to yellow after which crimson, relying on the general rating.

There may be analysis on Nutri-Rating however as I’ve mentioned many instances, simply because analysis exists, doesn’t imply it’s good analysis. This examine discovered associations (not causations) that utilizing this technique has advantages on well being and lowered mortality, however these findings have been weak total, and lots of elements equivalent to genetics and environmental elements weren’t considered. The examine used meals frequency questionnaires, that are notoriously inaccurate, to evaluate dietary patterns. They solely assessed diets at baseline, after which adopted up a number of years later. We all know that folks can change their consuming habits and way of life habits over time, so making conclusions primarily based on one survey at one cut-off date doesn’t inform us a lot.

I’ve written about find out how to interpret diet analysis right here.

If you use the Yuka app to scan a meals merchandise, it provides you a numerical rating out of 100 and a ranking of both “glorious,” “good”, “poor,” or “unhealthy.” For instance, the goldfish crackers I scanned got a rating of seven/100 (unhealthy) as a result of they’d components that Yuka says needs to be averted, and an excessive amount of sodium and energy in line with the app. Among the optimistic attributes given have been that the crackers had 3g of protein, and have been low in saturated fats. 

The pure peanut butter I scanned was given 69/100 (good), however misplaced factors for being too excessive in energy and saturated fats.

Categorizing meals as “good” or “unhealthy” is a horrible apply. It will possibly create guilt and disgrace round meals and consuming, and it’s fully arbitrary. There are not any good or unhealthy meals. Any meals can match right into a different food regimen, and meals ought to by no means be related to morality-based labels.

This type of narrative doesn’t assist anybody be more healthy (particularly emotionally – and that issues simply as a lot as bodily well being), and it tends to create extra confusion round diet. Peanut butter has a number of wholesome fat, nutritional vitamins and minerals. This isn’t the 80’s after we have been all avoiding fats. 

I can’t even think about anybody giving peanut butter factors off for being excessive in energy – it’s a NUT BUTTER. It’s additionally full of diet (and low in saturated fats!). High quality of energy issues!

Labeling meals pretty much as good or unhealthy may also create worry and nervousness round meals, and lead individuals to develop orthorexic kind habits the place they turn into overly targeted on making wholesome selections. That is horrible for our psychological well being and takes away from the truth that we don’t eat meals in isolation. It’s the totality of our diets that matter.

In case you’re consuming a food regimen filled with entire and minimally processed meals, you shouldn’t should care in regards to the ‘rating’ of your crackers or peanut butter or no matter.

The Yuka app ranks meals with larger quantities of saturated fat as “unhealthy,” or at the least lowers their rating. Dairy merchandise are notably affected by this ranking system as a result of they’re naturally larger in saturated fats. Tips for saturated fats consumption are to maintain it at lower than 10% of our whole calorie consumption. Once I scanned cheese, it received a low ranking as a result of it was too excessive in saturated fats and in addition misplaced factors for being too excessive in energy and sodium.

Meals comprise a wide range of vitamins, and whereas cheese could have extra saturated fats (in comparison with lower-fat milk or yogurt for instance), it’s a good supply of protein, calcium and different nutritional vitamins and minerals. Analysis additionally means that the saturated fats in dairy merchandise is just not a threat issue for irritation or coronary heart illness.

Lowering the rating due to one side is problematic, and letting that decide the general dietary worth of the meals, simply leads individuals to be confused about making wholesome selections. 

The calorie ranking system additionally appears a bit off to me. Cheese had 120 energy per serving and was deemed “a bit too caloric,” however 2% milk was thought-about “low energy” at 130 per cup. One meals could also be larger in energy than one other, however that meals may be extra satiating. As soon as once more, this categorization can result in obsessive behaviours round meals and counting energy. Not wholesome.

Yuka app and components

Earlier than I say something, let me share that I discovered this a part of their ranking system to be fully ludicrous.

It advised me that the monocalcium phosphate in Goldfish Crackers was “hazardous,” however the clarification they gave doesn’t show something. It solely states that getting an excessive amount of phosphorous can result in issues. An excessive amount of of something generally is a unhealthy factor, however in case you’re going to touch upon the risks of random components, it’s a must to qualify these feedback with the precise quantity of this additive within the product, and the way a lot of the product you would need to ingest to trigger hurt.

Extremely, the app additionally categorized the monosodium glutamate (MSG) in my daughter’s Takis as ‘hazardous,’ when science constantly refutes that. The 14 research that Yuka cites to again up their claims will not be convincing and seem like cherrypicked to go well with their narrative. Rodent research, cell research, outdated research, horribly completed research, even a examine that discovered no hostile results of MSG on people.

Perhaps Yuka thinks the common particular person isn’t going to verify their citations, however I positive as heck am.

I reviewed the analysis round MSG. Learn my publish about whether or not MSG is secure, right here.

This complete factor can result in chemophobia round meals, making individuals assume that what they’re consuming is poisonous. In actuality, all meals are completely secure. Meals components are nicely regulated in Canada and the US, and there are limits on how a lot can be utilized.

Ought to your food regimen be comprised fully of Froot Loops? After all not. However let’s method our diets with some nuance and science right here.

PS: Froot Loops received the next rating than Multigrain Cheerios and Goldfish crackers.

Natural meals and Yuka app

After the entire Yuka app ‘additive’ state of affairs, I’m unhappy to say that I’m not shocked within the least by what they are saying about natural meals.

The web site cites the well being advantages of an natural food regimen and states that natural meals are larger in antioxidants. Yuka states that individuals who eat extra natural meals have a lowered threat of most cancers, diabetes, and of being chubby or overweight. They cite research to again up these claims, however these research solely present associations and never causation.

That’s as a result of there are not any direct hyperlinks between natural meals and improved markers of well being. None.

I’ve really written in regards to the examine they cited that exhibits that individuals who devour extra natural meals have a decrease threat of most cancers. There was a media frenzy when this examine got here out, however what they don’t say is that individuals who eat extra natural meals are likely to have more healthy diets and life total in addition to higher entry to medical care, larger socioeconomic standing, and extra time for bodily exercise. These are all elements that may affect illness threat excess of simply consuming natural meals over standard.

When the Yuka app suggests a “more healthy” different to a product, it’s often an natural model that’s going to be dearer and this may lead individuals to really feel unhealthy about their meals selections, and we don’t want any extra of that going round.

Natural meals will not be nutritionally superior to traditional meals. With costs of meals already being so excessive, most individuals can’t afford to eat natural meals. As a dietitian, I don’t suggest natural over standard, and I don’t purchase natural meals myself.

There are many natural meals which might be ultra-processed, equivalent to cookies, crackers or frozen entrees. Whether or not natural or not, we needs to be consuming much less of those.

There may be completely no justification for Yuka to present an computerized 10% level bonus to natural meals, and it is a useless giveaway that the app is principally non-evidence primarily based rubbish.

Yuka app assessment: can Yuka assist us make higher meals selections?

In relation to processed or packaged snack meals that rating low on Yuka, the app will recommend “more healthy” alternate options. The alternate options could also be decrease in sodium or sugar, however are they actually going to be an acceptable different for the particular person primarily based on their preferences, finances, and many others?

For instance, the Goldish cracker’s top-rated different was an natural, gluten-free cracker that in my view, tastes like demise and in addition prices much more. What number of youngsters need Mary’s crackers? Significantly, even I don’t need these issues. Can we must be guilting dad and mom into shopping for dearer alternate options when the unique is completely secure?

If the app suggests, for instance, selecting an natural cookie that’s made with natural sugar, it might have the next rating, but it surely isn’t a more sensible choice. Your physique goes to digest that sugar the identical method as standard sugar, and scoring issues this fashion is deceptive. Sugar is sugar, and natural sugar is just not more healthy.

Most of us know what meals are nutritious and that make us really feel good. Probably the most nutritious meals don’t usually include a barcode that may be scanned, however not all the things we eat must be bodily nourishing. A nutritious diet has a wide range of meals….and no guilt connected.

Consuming extra entire meals and fewer ultra-processed ones is at all times superb, and we don’t want the app to inform us that. 

The dearth of science on this app’s scoring system, plus the worry, disgrace, and nervousness it might probably create round meals, outweigh any profit it might have. 

I wouldn’t suggest the Yuka app to anybody.
