Food neophobia is the fear of eating new or unfamiliar foods. It differs from selective eating disorder.
Food neophobia is particularly common in toddlers and young children. It is often related to an individual's level of sensation-seeking, meaning a person's willingness to try new things and take risks.
Food neophobia is a new field of study for researchers. They have no idea how many people suffer from it. It hasn't even been officially classified a disorder by the medical field, but it's starting to more serious than previously thought.
Those high in food neophobia appear to associate many avoided foods with a sense of disgust.
