I regularly combine red meat and fat, as bacon and as tallow-cooked steaks with fat on them. My iron has never come back high, yet. But I also often take a few days off red meat here and there, when I eat my chicken and fish after the steak and bacon is gone. Maybe the rest period lets my garbage men balance things out. Oh, and daily fasts probably help, too!
Perhaps for people with iron problems this is important.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
