Alternative Names: Selective Eating Disorder (SED), Picky Eating, Fussy Eating, Perseverative Feeding Disorder
Picky eating is a disorder that prevents the consumption of certain foods. It usually occurs in children and animals, but that is not always the case. Picky eaters may be born that way: the ability to taste sweetness and bitterness may be genetically related to the number of taste buds on a person's tongue. The so-called genetic supertaster, for example, may have as many as 1,100 taste buds per square centimeter of tongue, while a more accepting eater may have as few as 11 taste buds in the same-size area [The Yale Guide to Children's Nutrition edited by William V. Tamborlane, M.D.]. A study from the American Dietetic Association showed that even though 49% of mothers considered their children to be picky eaters, all of the children in the study actually consumed a wide enough variety of foods to meet their nutritional needs.
"Selective eating is the little-studied phenomenon of eating a highly limited range of foods, associated with an unwillingness to try new foods. Common in toddlers, it can persist into middle childhood and adolescence in a small number of children, most commonly boys. When this happens social avoidance, anxiety and conflict can result." [Clinical Child Psychology and Psychiatry, Vol. 6, No. 2, pp. 257-70 (2001)]
Food allergies are sometimes addictive in nature, requiring continued consumption of the allergenic food in order to prevent the appearance of withdrawal symptoms. However, eating the same foods over and over increases the likelihood of eventually becoming allergic to them.
