Salivary amylase (starch digesting enzyme) starts things off in the mouth. This stops in the stomach when pepsin (protein digesting enzyme) takes over. Then in the duodenum, bile salts and other enzymes (can't be bothered to look all this up) digest fats. Then, in the small intestines, more carb digestion takes place (I think) and so on. Some enzymes work in acid conditions, some in alkaline and some almost neutral.
Millions of years of evolution or w.h.y. have resulted in us being able to eat animals (protein + fat) and nuts (protein + fat) and legumes (proteins + carbs) and so on. The only thing we have not evolved to eat is junk (carbs + fat).
Where's TCD when you need him? He knows all about this stuff.
