Well, it's... what we've been told to do (at least in the rest of the world) for more than a century? Packaged as some "app-like" / "tech-like" website?
Pathetic
If the old wisdom is correct then there is no issue in regurgitating it in a format suitable for a modern audience. We departed from it for a very long time, especially in regards to fat and processed foods. America has been been on a sharp decline in diet-related health.
The deeper problem is that you can feed a family with a few bucks at a fast food joint. Eating correctly costs money, money that Americans don't have.
I don't think there was guidance to avoid ultra processed foods 100 years ago anywhere in the world. I don't believe that concept even existed, let alone was promulgated by health authorities. But I'd lkvd to be proven wrong.
