Continuing discussion on food allergies, there is concern amongst dietitians in Australia that people are self-diagnosing themselves as having food allergies and intolerances. While avoiding a food items is not the issues, there is a problem:
The number of adults being diagnosed with food allergies has remained constant, but the number of people incorrectly self-diagnosing food allergies and intolerances has skyrocketed,’ Ms Graham said.

Not mentioned in the article is that fact that if wheat or dairy are being excluded from the diet, the diet could missing essential nutrients and sufficient energy, especially for children.

Good point. I’ve known people who have serious food allergies, and they need to make an effort to be sure of getting proper nutrients to replace those they’d be getting from an allergy item. This is why I went through all the testing in 2003 to be sure I didn’t have celiac, though it seemed highly unlikely. I wanted to KNOW for certain what dietary issues I had, if any, to be able to properly care for myself and to deal with nutritional difficulties.
