Yuka classifies Plenny Shake as "Mediocre"


A couple friends have shown me lately a smartphone app called Yuka to evaluate the “healthyness” of the food you buy at the market.
For some reason, it scores Plenny Shake as “Mediocre” with 27 points out of 100, mostly due to use of E917 (Potassium iodate) tagged as High Risk, and E955 and artificial flavoring, both tagged as “Limited risk”.

Aparently it’s also a little bit salty 1,09 per 100gr vs the 0,92 per 100gr.

Just to let you know.

Hi Randur,

Thank you for your message! We are indeed aware that Yuka classifies our products way below standards we would expect. Unfortunately, because of their way of standardising what healthy is and what not we have no influence on this. For the public an app like this is generally a good thing since it simplifies many choices you make while grocery shopping on a daily basis, but it has its flaws (any nutritionist will confirm this). In other words: Our meals are designed to be as healthy as scientifically possible, but apps like Yuka are not designed to dissect fairly complicated formulas like ours.

Here is a little bit more info on the topic: https://www.reddit.com/r/JimmyJoyFood/comments/chbi70/yuka_rated_the_twenny_bar_vanilla_24100_2/

Hahahaha, Yuka…
Nobody knows how they calculate their score. No transparency.
Their estimation on additives is based on rumors, or very few studies. I have found other sources, saying taht E917 is safe, but hey, they choose only the warnings… Fear sells.
They are purely ideological: for them, additive, or created by humans = evil, without any compromise. Nature = good.
Last but not least: they also sell their own nutrition coaching programs. Both judge and judged, it seems legit, right?…


Yuka is based on very few scientific studies and its notation system isn’t clear. Some criteria are purely based on faith (all organics products have a bonus for instance, and all synthetic components have a malus). So no synthetic food can have a good score with this application, because it’s essentially fear mongering and biased data.

Contrary to @otto, I don’t even think Yuka is a good application for the public because it participates to propagate bad science and irrational fear about food products. And this fear can have health consequences (like useless gluten free diet for many people, with low nutritional value).

If you can read french, this is a good article about the Yuka bias: https://www.jim.fr/e-docs/yuka_trop_bio_pour_etre_vrai__181253/document_jim_plus.phtml

Hey, thanks for making us more aware about this! Because Yuka only seems active in France I don’t know all the details about it, but there have been some rumours that the Dutch “voedingscentrum” is working on introducing a similar kind of scale, the Nutri-score (which I think is also French?).

Yes the nutri-score is french, and more scientifically grounded. Their score doesn’t seem to differ between two products with the same nutrional profil.

The app is also well known in Spain aswell.

Nutri-score is science-based, all information about the protocol and algorithm is public and reviewed by peers. And its team does not sell any nutrition coaching programs. It is not a company.

Yuka is totally based on belief and faith ; it all obfuscated ; its team is a company, and sells its own nutrition coaching programs and services.
