Sandi, I'm going to include your original statements and answer each individually, O.K.? My answers will be in all-CAPS to distinguish them from your questions. Here we go... 1) I am aware that proteases breakdown protein, and amylase breaks down starch. If a person consumes both proteins and starch together, then both will be in the small intestine at the same time with amylase and protease being produced correct? YES, THAT'S CORRECT. 2) Based on above being correct, does amylase and protease counter act each others effectiveness? In other words, is protease more effective without amylase being produced at the same time? And the opposite of that, is amylase more effective when protease is produced? IF THERE WERE NOT ENOUGH AMYLASE PRESENT, THEN PERHAPS THERE WOULD BE A PROBLEM. I SAY THIS BECAUSE ENZYMES ARE PROTEINS, IT MAY BE POSSIBLE FOR PROTEASES TO DEGRADE SOME AMYLASE PROTEIN. THE BODY PRODUCES A LOT MORE OF EACH ENZYME THAN IS NEEDED, HOWEVER, SO THAT THE DEGRADATION OF SOME OF THE AMYLASE, EVEN IF IT DID HAPPEN, WOULD HAVE NO EFFECT ON THE OVERALL DIGESTIVE PROCESS. 3) If they do counter act each others effectiveness, how much longer is the actual digestive process as a result? As compared to a meal of protein and vegetables only, or starch and vegetables only, and not combining the two? AGAIN, THE ENZYMES ARE NOT THE LIMITING FACTOR. THERE ARE A NUMBER OF THINGS WHICH CAN SLOW DOWN DIGESTION, HOWEVER. THESE INCLUDE: EATING A HIGH FAT MEAL EATING POORLY COOKED OR OVERCOOKED FOOD EATING A VERY LARGE MEAL (IT IS POSSIBLE THAT THIS COULD TEMPORARILY DILUTE DIGESTIVE ENZYMES AND THUS SLOW DIGESTION). 4) Does any of this process take longer in the stomach while combining proteins and starches? Does pepsin and HCI work equally as hard on both when they are combined verses eaten alone? PEPSIN ONLY BREAKS DOWN PROTEINS. 5) Is eating a big meal the reason people feel miserable for hours, or does food combining play a big role in it? PLEASE SEE THE ANSWER TO QUESTION 3. I HOPE THIS HELPS. GABRIEL
