Subject: question about protease and amylase

I have read several books lately that suggest that combining proteins with 
starches puts stress on
the digestive system because of the extra work load placed on the body to 
break
down both carbohydrates and proteins.

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?

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?

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?

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?

5) Is eating a big meal the reason people feel miserable for hours, or does
food combining play a big role in it?


Thanks in advance for all of your help!!
