There is no food that can add to our salvation or make us holy. There is no food that can save or condemn. This includes those things which might not be considered pure food. None-the-less God has ordained a diet for the human race. There are foods that "God has created to be gratefully shared in by those who believe and know the truth." And this diet does not consist of rocks, rubber, wood, poison, or any other non-food substance.
