While searching for the cause of an edema? internal oral swelling of tongue and cheeks, I seem to have "landed" on soy and products with soy. Example, first thought it was Teriyaki then further rooted to soy. Then find that "soft gels" regardless of internal ingredients, seem to be made with soy in some manner. Am I correct, that soft gels are composed of soy products? Has anyone experienced or heard of such?View Thread
