Well, here's a good visual. If you leave a stick of butter and a stick on non-butter on the counter...bugs will eat the butter immediately. The non-butter will sit forever and nothing will eat it. Why? Because, no other life besides humans, thinks it's food. Animals, organisms, bacterias, insects (not even mold!!)...can't even compute it is "food." Margarine has bad cholesterol, and bad fats in it. It increases heart diseases, decreases the immune system, and has all kinds of other bad affects in your system. When margarine is made, it actually comes out as a gray, sloppy substance. They then have to coloring and deodorizing agents, to cover up the look and smell. (It smells awful and rancid.) Margarine is ONE molecule away, from being considered plastic. The margarine industry came out and said, while it is one molecule away from plastic, it's because the molecules are "arranged differently," so it's really not. Uh-huh. Right. Basically, your daughter is dining on a gray slop engineered "food" substance, that's molecules are rearranged to appear like food and not plastic, and no other organism on earth but humans will touch it...and that's only because our brains can convince our mouths, that it's something we can call food.
Yum??
