Hi, Paul- no, I wouldn't go so far, as I don't "test" lectins..but I do test body stress response to all things. Yes, in a particular case, onions neutralized the stress response to potatoes- other foods and nutrients have responded in similar ways. As the testing has addressed the body as a whole, I have not at this point broken it down to systems, tissues, organs, etc..(for this purpose) but it is easy to do, and I will since being made aware of this ER4YT works! The testing can also be quantified on a scale of negative- positive, toxic- beneficial. This is why I would like to see if there is or will be, any direct blood research! It could be liberating, to say the least! It was pointed out as a result of the same query, that potatoes are pro-fungal, and onions anti-fungal, which explains a bit. Thanks for your response!
