There are so many great benefits to honey, but quality is the key. Definitely do your research and pay the extra money for organic, local, quality honey, as mentioned by others in this thread.
As honey bees die off, production is still rising of honey. The only way that makes sense is the fact that honey is cut with other products/syrups, etc. There is a great episode of Rotten on Netflix that sheds a lot of light on this topic! http://www.imdb.com/title/tt7830582/
