Instances where certain foods are consumed frequently for reasons other than for providing needed nutrients.
A food fad refers to an intense preference or aversion towards specific foods, which is amplified to an extreme level. Such fads can result in an excessive dependence on or avoidance of certain foods. They are often observed in toddlers, teenagers, and individuals undergoing stress. However, if such a fad becomes an obsession or continues for an extended period, it might signify a severe eating disorder.
