Iodine status and thyroid function in children with multiple food allergy: a prospective cross-sectional study.

Children with multiple food allergies (multiple food allergies) often follow elimination diets that restrict major dietary sources of iodine, thereby increasing the risk of iodine deficiency.

This study aimed to evaluate urinary iodine concentration (urinary iodine concentration) and thyroid function parameters in children with multiple food allergies and to compare these findings with those of age- and sex-matched healthy controls.
