meats are processed by strong acids in the stomach and starches are processed by salivas/alkalines(usually in the mouth or small intestine as stated above). Search the internet and you will find that this is true that this really is how the two are processed differently, and if so, you're logic should tell you then if you ate the two in the same meal, then the meal will no be digested thoroughly, leaving undigested food in your intestines and therefore causing rotting food in your stomach, toxins being released, and body fat to cushion the toxins.  The constant repetition of heavy protein-starch meals taxes their digestion to the limit and, sooner or later, results in discomforts and diseases
