As stated above, grain's plan is to be eaten whole and pooped out somewhere else. Not digested, for the most part. Granted, some animals have broken the code (rodents, for example) and beaten the plant's plan. But not this human. I eat grains and fart, get gut and joint pain, etc. A little rice does seem to be okay on occasion.
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.
