Why is honey the only food item that does not spoil?

Spoilage of food is mainly due to infestation of microbes.
Microbes in food, like almost every other living being, need water.
Honey has almost zero water content. If there are microbes in honey, they would soon lose whatever water they have in their cells to the the surrounding honey, due to osmosis and perish.

You can apply this same rule to oil as well. Edible Oil is a very good natural preservative for perishable foods (e.g. pickles from Indian sub-continent), due to the absence of water.
