This may sound simple at first, but think of all the things we consume in this age of technology and food production. Chemicals, dyes & colors, 'natural' and artificial flavors (which are both artificial, by the way), fillers, fat-replacing chemicals, and the list goes on and on. We may not even realize what's in the foods we eat and love until we read the ingredients on the label.
Here's a clue: If you can't pronounce it and don't know what it is, it's probably not a substance created by God for human consumption.
Here's another clue: What you don't know can hurt you. Read those labels.
What did God say?
"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
God thought it all out. He created man and what he would eat. His desire was to please man's palate, but He set boundaries for man's protection. Isn't it interesting that man's first sin was to eat something that was forbidden?
