While we're having this conversation, I'd like to remind everyone of that time George Q. Canon added "hot soups" to the WoW (1868).
But vegetables are not grown among us as they should be; there is not that attention paid to them that, it seems to me, they should receive. My theory is, that if we wish to raise a healthy, noble looking, intellectual and perfect race of men and women we must feed our children properly. We must prevent the use by them of every article that is hurtful or noxious in its nature. We must not permit them to drink liquor or hot drinks, or hot soups or to use tobacco or other articles that are injurious. I do not believe that you could ever make as great and noble race of men, if you feed them on one article of food alone, as if you gave them a variety of diet. We have illustrations of this in India, where the chief diet is rice -- of itself a very good article of food. We have other illustrations in the case of other races.
I bring this up because maybe rather than trying to list the items not explicitly denied by the WoW, we accept the WoW as a failed and frequently altered theory of the 1800s, and move on with life.
