No matter how greasy, no matter how much extra cheese, or how much white sugar, no matter how indigestible a food is, your body will try to break it down by means of enzymes. Some foods are very easy on the body. Turns out, those are the ones which contain within them all the enzymes necessary for complete digestion.
