Selective eating disorder (SED) (also known as perseverative feeding disorder) is an eating disorder that prevents the consumption of certain foods. It is often viewed as a phase of childhood that is generally overcome with age. Children may not grow out of the disorder, however, and may continue to be afflicted with SED throughout their adult lives.

SED Defined
Selective eating disorder lacks formal diagnostic criteria and classification and is not currently listed in the Diagnostic and Statistical Manual of Mental Disorders. The current section "Feeding Disorder of Infancy and Early Childhood" in the DSM-IV requires that the child fails to maintain weight, develops symptoms before age 6 and is not caused by another mental disorder or medical condition. With these criteria, children that selectively choose their foods or experience anxiety when trying new foods but maintain a healthy weight, are excluded from this diagnosis. SED is currently up for consideration to be added to the DSM-V.

Symptoms
Sufferers of SED have an inability to eat certain foods based on texture or aroma. "Safe" foods may be limited to certain food types and even specific brands. In some cases, afflicted individuals will exclude whole food groups, such as fruits or vegetables. Sometimes excluded foods can be refused based on color. Some may only like very hot or very cold food, or only very crunchy or hard-to-chew food.
