I don't know about that. When I lived in England, my house (rented) was in the middle of a large sugar beet producing area. The farmers said that nearly all of their beets went for sugar. Only the local people and restaurants actually ate their beets as beets.
One local cook at a restaurant I sometimes ate at admitted that he got many of the beets served at his fine establishment off of the side of the road, after falling from a farmers truck. Of course, he served vegetables in the time-hounoured British way, boiled to within an inch of dissolving, so germies were not an issue.
I meant they use cane sugar for soft drinks, but generally speaking beet sugar is perfectly fine too!
