According to the article:
[T]he fruitcake makers maintain that the current serving size -- a wedge about two inches high and two inches thick -- is "overindulgent and probably unhealthy." Adds Bob McNutt, president of Collin Street Bakery in Corsicana, Texas, "Our fruitcake is like a fine wine. You take a taste, it kind of leaves you with this long, nice finish."The urban legend debunked?--There are really only a few fruitcakes in existence at any one time. Those fruitcakes are never eaten, merely passed as "gifts" from one family to another.
The bakers' 13-page petition calls on the FDA to "describe fruitcake as the food commonly known as fruitcake." It underscores the product's uniqueness ("Gertrude Stein would say 'A fruitcake is a fruitcake is a fruitcake!' "). It also clarifies who eats the concoction ("Fruitcake is consumed by all populations, but rarely by infants."), and it distinguishes fruitcake from other high-density cakes. ("No products are 'closely related' to fruitcakes. They are sui generis and for decades have been recognized by all population groups in the U.S.")
