are multiple food allergies leaky gut symptom

My daughter is VERY limited in her food choices, b/c she is allergic to so may foods, even things like apples, peas, green beans, rice...is this typical with leaky gut, we have been avoiding these foods for some time now, is there any hope that in the future she will be able to eat more things...at the moment her naturopath is chelating her with dmsa for mercury and lead. thanks again..jennifer Tweet
