The root purpose behind all dietetic judgments can be found in 1 Corinthians 10:31. To start from the very beginning, I suppose we have no reason to assume that there was any chemical pollution (per se) in the fruit that came from the tree of the knowledge of good evil. God had said, "Don't eat it!" – that was ultimately the only thing that mattered. Going one step further, I don't know that any argument can be made that Jesus' body (and certainly not the bread which we eat representing it) would have had any physical peculiarities to it… if samples of it had been examined under a microscope (Isaiah 53:2 & Romans 8:3). God's judgment on anything is the quintessential determinate of its wholesomeness or repulsiveness. There is no intrinsic beauty in anything apart from the reflection of God's character that can be seen in it. Hence, spiritual realities are more significant than material ones. In fact, material matters only serve to illustrate, demonstrate and indicate spiritual conditions (II Corinthians 4:18).
