Studies show that genes play a major role in determining who becomes a picky eater, including recent research on a group of 4- to 7-year-old twins. Part of the pickiness can be attributed to specific genes that govern taste.

Picky eating habits are more likely to develop when parents punish, bribe or reward their childrens eating behaviors. The goal for feeding a picky eater should be to try new foods and to keep food from starting a battle.
