Food for thought

A friend of mine used to frequently say, "salad is not food. Salad feeds food."

This statement is not wholely correct. The human body cannot digest food without assistance... it simply does not have the ability by its lonesome to do so. Salad passes through the stomach, becoming a mash, which further enters the duodenum and intestines, where the mash is ravaged by microorganisms that can digest plant matter. The nutrients we digest aren't used by those organisms, who excrete what we then assimilate.

Symbiosis is a beautiful thing.
