Bible Foods - I'll never give up on trying to teach this

What's an example of something that's not food that we eat?
Well according to God, pork, shellfish, lobster, crab, all the scavenger foods. But also artificial sweeteners, margarine, the hydrogenated oils. I don't think white sugar is a food. The Bible talks about pork and shellfish, but obviously not aspertame or hydrogenated oils. But to me that's in the same category. They're not food, they're chemicals.

Deuteronomy 14 (Amplified Bible)

For you are a holy people [set apart] to the Lord your God; and the Lord has chosen you to be a peculiar people to Himself, above all the nations on the earth.

3You shall not eat anything that is abominable [to the Lord and so forbidden by Him].

4These are the beasts which you may eat: the ox, the sheep, and the goat,

5The hart, the gazelle, the roebuck, the wild goat, the ibex, the antelope, and the mountain sheep.

6And every beast that parts the hoof and has it divided into two and brings up and chews the cud among the beasts you may eat.

7Yet these you shall not eat of those that chew the cud or have the hoof split in two: the camel, the hare,and the coney, because they chew the cud but divide not the hoof; they are unclean for you..

Romans 14

3Let not him who eats look down on or despise him who abstains, and let not him who abstains criticize and pass judgment on him who eats; for God has accepted and welcomed him.
