Geez are you serious?
You are confusing digestion with absortion in many of those points (while some are just incorrect). Primary digetsion is breaking down solids into chyme then breaking down chyme to be absorbed into the bloodstrem through various pathways. The makeup of a meal and its individual properties determine how digestion/absortion takes place. Stating protein digests this way and carbs digest this way is incorrect becasue even within those macronturients there are varitions that determine how much and how fast gets digested and absorbed. There are simply too many variables to make blanket statements about macronutrient digestion.
Example: A steak will take much longer to digest because of its fat content even though its an extremely high protein source. The protein portion has little to do with the intial stages of breaking down fats into lipids and until that is accomplished the protein portion won't be absorbed.
Too many variables.
The majority of delay when it comes to fats is either
a) When they are in a solid state and it delays the breakdown of bolus (solid like state) into chyme (semi-liquid) state. With a shake, this process is already complete so that delay is almost nonexistant....Think of red meat and the difference in fats vs. oils.
b) The emulsification of saturated or transfatty acids within the small intestine. At this point the absortion of amino's is already taking place.
So in general when your fat amount is about 1-2tblsp within a liquid state already (thanks to your blender) the delay in amino absortion is almost non-existant.
Whole foods are where fats delay digestion the most. Even then the actual absortion of nutrients (amino's specifically) isn't altered that much. The process of breaking down whole foods and trasnfering them to the lower part of the stomach and into the small intestine is just a much slower process because of its makeup.
For the record the stomach only goes through 2 steps of protein assimilation whereas the small intestine has 8. But I am sure you knew that.
