"A food allergy test would provide some information about sensitivities which otherwise we would probably not be aware of..lots of people are walking about oblivious of their sensitivities...so in essence it would be quicker..but somehow by walking through this i'm learning alot about food and particulary as food as your medicine along the way and getting to familiarise myself with whats what..but sure a mineral anyalysis and food allergy test makes alot of sense...now!"
Not sure if this gives much conclusive information, but I have done an allergy test at the dermatologist to confirm any food intolerances I might have. It appeared that not any of the frequently used, potential allergens (ie garlic, sugar, lactose, bell pepper, cinnamon and several others (If really interested, I could request more specific information from my doctor)), induced an allergic skin reaction to me. This was done by a validated "back-sticker" test: a systematic intolerance to any of these allergens would pose a trigger for an eczematic patch on my well-vasculated back. As said, none of the common food-constituents appeared to be allergenic to me.
I'm not sure if this gives reason not to suspect any sensitivities to any of those at all... I guess testing hypersensitivities is a challenge in itself.
