Eating from too many different food groups at one time

When early humans ceased being hunter/gatherers that would eat from just one food source at a time as the food was discovered, we started to develop many of our modern diseases. Buying our food from supermarkets today also just adds to our insatiable desire for mixing too many food groups together in one meal. For instance, a few things that digest terribly when consumed together are: meat and carbs such as bread; meat and starches such as potatoes; or fruits and nuts. But the best thing to eat with meat is raw vegetables, because the enzymes in the vegetables can actually aid in digestion and help the meat to not get stuck in our colons too long. If we are not having at least one good bowel movement every day the end result will be constipation; this should be a loud signal that our body is becoming more toxic. 

For optimum digestion, certain foods need to be eaten separately from other food groups. For example, if a person consumes proteins, starches, carbohydrates, vegetables, some fruit - then perhaps a sugary desert of some kind; the stomach may release many different digestive enzymes causing fermenting and putrefying of that meal. So, when possible, we should eat different food groups separately - or wait at least half an hour between eating different food groups.
 
It is both the over-abundance of food and the mixing of too many different food groups (fruits, vegetables, meats, carbs, starches, etc) that makes us sick because they all require different stomach acids for proper digestion. And it is such a condition that also ultimately causes the final state of waste in our colon to become very putrefied and fermented.  This final state of degradation inside our colons is what ultimately leads to increased toxicity of our whole body.
