no, total con.
esp not for children.
quacks often give children a long list of foods to avoid, without a careful dietary plan ............and there have been cases of children getting rickets from following such alternative practices.
has been calls from nhs immunologists to get these banned from this country, as they are in other countries.....
so, no , would not advise you to go to see one.
also, has been proved , countless times to be totally unreliable, and often such huge lists of food to avoid, is going to hit on some of the problem foods.
if you think you have food intolerance, go and buy a decent medical book on it, and follow a exclusion diet (if you are a adult) or if you suspect intolerance related to your child, get your gp to reffer you to a state registered dietian , and perhaps a allergy clinic/immunologist.
