I've recently cut out some foods that aggravated stomach distress, I'm feeling better and also receptive to trying new foods, because the foods I did eat, I can't anymore. As there are few foods I will eat, I've had to find others and it's easier this time, something seems to have shifted in my perception. I've suffered stomach ailments since childhood, this is hopeful news. According to a preliminary online survey by researchers at the Duke University Center for Eating Disorders, extremely picky eating may be more common in adults than you think. Theories are often associated with Obsessive Compulsive Disorder or autism. Research indicates Selective eaters may experience food differently than other people: they tend to reject food because of look or smell, YES- rather than taste, and they often have had early negative associations with food, like stomach problems or acid reflux in infancy, reported by LiveScience
