Scientists at Duke University in North Carolina are compiling the first global registry of “picky eaters” in the hope of discovering why some people have trouble with food. They believe it may help find a genetic reason for some eaters’ intense dislike of certain foods, like broccoli, or beans with a “fuzzy” texture. They note some eaters’ pickiness is so deep-seated it interferes with their jobs, their relationships and their social lives. – Hate fish? Can’t eat veg? Doctors study picky eaters from BBC.
Empathy through evolutionary psychology: Picky eaters may survive better in some circumstances and omnivores in other, which is why we as humans have both possibilities, and why we as individuals are genetically predisposed to one or the other, and our environment brings one or the other out more prominently. It’s all natural.
