Everything about whether or not a food is Paleo really comes down to 2 questions…
1. Is it nutritious?
2. Is it potentially toxic?
Unless we’re talking about a specific person’s reaction to a food, those are really the only 2 questions that matter.
Healthiness is a Spectrum
Asking these 2 questions doesn’t mean that any particular food needs to be the most nutritious food that you could eat or that it needs to be 100% non-toxic. It’s really more of a spectrum.
