Changing "Hates fruit" to "Fructose intolerance"

I think this would fit better. Fructose intolerance/malabsorption seems to be common in the real world and this would explain better why you are unable to digest fruit properly (you obtain less nutrition from eating fruit).
In real life it appears that very few people actually outright hate fruit, especially because there is a huge variety of fruit and it tends to be sweet, so many people like it.

Since I have firsthand experience with this, it is unobtrusive enough to not outright kill you but it is indeed annoying and comes with a morale penalty, so I think a rename would improve this.
