> Kirk Andersons work clearly shows there is no beifit or need for bee bread and bees prefer the fresh food.
I think this misrepresents what they found. Bees did prefer fresh pollen, but they did not say there is no benefit nor need for bee bread. They were making the point that bee bread is not improved by microbial fermentation, as some had supposed.

To the contrary, they found that the bees add honey as a preservative and the pollen is not degraded as a result. In plain words, if they can't get fresh, the preserved pollen is just as good -- but not better.
