I would tend to agree but I have heard reliable people in the carnivore/nutrition/regenerative agriculture space who say that grass fed is not critical, just potentially a little more beneficial. I’m making up numbers here but just getting off the standard American diet and onto a seed oil free, whole foods diet gets you like 80% of the way there. I personally went carnivore to get the rest of the way but I have not prioritized grass fed so maybe I still have a few percentage points I could improve
