your protein digest ratio will determine how much you intake at a given time.
chewing takes only few seconds as we try to broken up the food in the mouth, moistened with our saliva, and formed into a ball or bolus for easy swallowing. The amylase in our saliva is responsible now to break down the starches and simple sugars in our food before it travels down to the esophagus then down to the stomach. Please take note that the longer we chew, the faster the digestion would take place because the rate of digestion speeds up as the food is broken down and chewed properly.
Fish and Sea Food would be my pick of be more rapidly absorbed by the body while steak would be the slowest!
Meat may stay in the intestines for 24-72 hours and still depend on its type. Likewise, red meat in particular takes 1-3 days to complete the digestion process because of fat content and high protein,
Even the quick digesting foods have to wait until the slowest digesting food like meat leave the stomach. This process may take up to 6-8 hours. To be more exact on the digestive time of various proteins, egg yolk digestion time is around 30 minutes; the whole egg is approximately 45 minutes; fish which is less fatty like sole seafood, cod, flounder, and scrod takes 30 minutes to digest; while more fatty fish including salmon, herring, salmon trout can take 45-60 minutes to digest; the chicken without skin can take up 1 1/2 – 2 hours before it leaves the stomach (what more for chicken with skin?); the turkey without skin is much longer to digest because it can stay 2-2 1/4 hours of digestion; the most favorite beef and lamb can really stay 3-4 hours; lastly, the pork which is always part of the meal can take 4 1/2- 5 hours to digest.
Now, if the stomach is full, what happens to other foods ingested together with the meat like carbohydrates, starches, vegetables and fruits? While they are waiting for the stomach to be emptied, they undergo fermentation that produces acid, gas, and the most common indigestion problems.
So in Summary it's best to eat the faster ,waterly digesting foods before meat!
