An aversion of unfamiliar tastes: Somehow Tim, suffering from geumaphobia, always avoided anything new to eat, fearing that the food would be unpleasant or even bad, and therefore there were only a very few restaurants he would go to.

With an inability to smell, such phobics may fear that since they can no longer smell previous items, they might be eating or drinking something that formerly caused them anxieties.
