after reading Redwagon's other two posts, but then I remembered my nephew - and his acidly burned mouth due to his allergy (sensitivity) to oranges.
I could then see, where his head could have been skewed from this type of information and re-thought things through.
Also, my niece was told she's "allergic" to calcium!
I figure, if people are "told" by a medical official they are allergic to Iodine (like I was told back in the day), then, perhaps today, some are told the same thing about other things the body actually needs.
I decided to give Redwagon (and others reading her posts) the benefit of the doubt - especially when she said that kelp (which has Iodine in it) helped her.
