A few weeks ago, my wife told me about an app called Yuka. What it does is scan the barcodes of food products and cosmetics and then give you a health rating out of 100. You can also drill deeper if you'd like to better understand why a particular food item is healthy — or not healthy.
Since then, a few things have happened:
I've told as many people as possible about it. (I have my parents scanning at the grocery store.)
Grocery shopping takes a lot longer. (I have a colleague who has been mistaken for a store employee while using the app.)
We've made meaningful changes to the food we buy.
And it's not like we weren't trying to shop healthy before.
It works a lot like France's Nutri-Score, except you have to do a bit more work. As soon as I see a low score, I no longer want the product and I move on to an alternative or I eschew it altogether. I can only imagine the positive impact that an app like this will have on our health and on the broader food landscape as our individual decisions compound over time.
