For the record, tomatoes do not need bees for pollination. Tomato flowers are self-fertile, the wind is enough to pollinate the tomatoes. The pollen, however, may be attractive to the bees, same as corn, another plant that doesn't need bees for pollination. I have no idea what the nutritional value of tomato pollen is, but I do know that corn pollen isn't the best for the bees, but they don't seem to care, they gather it anyways.
