A true carnivore eats very few vegetables, and those are largely predigested in the gut of prey (easily substituted with fermented vegetables if desired). Complete nutrition (and then some!) is easily found in a vegetable-free diet. Eating entire animals, seafood, eggs and a few berries and other fruits completely covers all RDA and usually vastly overshoots them at 3000 calories a day. So a virtually phytate-free diet is easily attainable. And I do find it interesting that the fewer phytates a food has, the more nutritious it tends to be. Coincidence?
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.
