You have it backwards. No food is inherently “good” for you. Most people are better off skipping meals until they absolutely need nutrients. There’s toxins in all food.
Another note: there is no such thing as “toxins” in food. Barring things like heavy metals, and actual poison. You won’t see any research about nutrition and food talk about “toxins” in a context like this.
There's toxins in all air, but we don't hold our breath until we need to breathe...
I mean we kind of do. If everyone breathed like they ate(in the US) there would be people fainting all over the place.
