Scott Hildenbrand expounded:
No, pollen is most definitely a source of food, lipids, vitamins, sterols, minerals, micronutrients and most importantly protein, some within the worker bees' bodies in the form of vitellogenin and some of which is stored as beebread. Honey comes from nectar gathered and processed in the workers' honey stomaches and is also used as food, mainly carbohydrates they burn over the winter to keep themselves and the all-important queen warm until spring. There's more involved, but books have been written on bee nutrition, I'm not going to bore you all with the rest of it
