When I was on my Colonix program, I didnt really pay attention to what I ate and the results were still wonderful. However, Im not much of a meat eater. If you drink plenty of water you should be ok. Never use margarine...From what I know margarine was created in order to feed turkeys and make them bigger for sale. When the makers of margarine noticed it was killing the turkeys, they had to figure out how to make money out of it no matter what. Thats when they started selling it to humans. From what I also know, if you put butter and margarine outside for a few days, mold and other life forms would start to grow on the butter, and the margarine would stay untouched. Margarine it seems is one atom property away from being plastic..And eventually it will turn hard. Nothing can live off margarine, stick to butter! Ghee! Colonix is a great program, I want to order it again soon. Just remember to drink 6-8 cups of warm water a day. You will be fine.
