According to the Bible, which I firmly believe is the truth, we were originally fruits and vegetarians.
Genesis 1:29 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."
It also says in verse 30 that all animals were given every green plant for food. No carnivores yet.
When Adam and Eve failed God's command and ate from the tree of knowledge or good an evil God added another twist to the human diet. In Genesis 3:17-18 God says. "17....cursed is the ground because of you: through painful turmoil you will eat of it all the days of your life. 18 It will produce thorns and thistles for you, and you will eat the plants of the field."
It seems at this point in time man would have to work the fields for his food. He would have to deal with weeds and earn his food. The plants of the field included vegetables and grains. No longer could he just go and pick fruit, eat, and be happy.
When God flooded the earth and only Noah and his family was spared another twist was added. This was the 2nd major downfall of man. Genesis 9:3 God says, "Everything that lives and moves will be food for you. Just as I gave you the green plants, I now give you everything."
At this point in time animals also began to fear man. The whole predator-prey food chain started as well. If you think about it there would have been no vegetation or fruit to choose from if the earth had been flooded. Protein was now added into the mix. There were some stipulations about which types of meats and such since the sacrifice of animals would come into play
Since a friend from church brought up that I hadn't posted in a while today I posted on my Crave The Word blogsite about signs from God. Tomorrow I am going to post a passage from Daniel pertaining to the Daniel diet which I am going to do for 10 days. I'll tell you about it Monday night.
