If we look to the Bible, we can find out what the diet was that God intended for humans ... fruit and seeds. This lines up with what science shows us when we study the human body. That our body is designed and does best on a fruitarian diet. Isn't that incredible?
Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food." - Genesis 1:29
