Stomach bloating causes: Apple juice could be to blame - why you should avoid it

A common misconception is that allergies to bread trigger stomach bloating.

“Probably a third of patients in my allergy clinic complain of digestive symptoms such as bloating, diarrhoea, vomiting and stomach pain after eating bread,” said Isabel Skypala PhD, specialist allergy dietitian at the Royal Brompton and Harefield NHS Foundation Trust.

She said that allergies are unlikely to be the culprit, but bread-related symptoms are real, and wheat could be to blame.

“Some people find certain foods are simply hard to digest, and wheat appears to be one of those,” she explained.
