Our youngest son is working through the process of "heal-thy" self. He is at present on a vegan diet with the exception of a couple of pastured eggs from our girls weekly. We have a food allergy test run on him last week to be told he can't eat fish or shellfish and we need to minimize dust in our home. Saturday he ate vegan shrimp from Sophie's Kitchen and we watch him break out in hive with itching inside his mouth and along the outside of his throat. He took a benadryl to sleep it off. The next morning we muscle tested him to find seaweed causes weakness in his body. We used the second technique at this link http://www.ehow.com/way_5234610_muscle-testing-techniques.html .
I have been adding kelp and dulse seasonings to our food for some time know for the "heal-thy" iodine source.
