I am reading up on all of this. Pineapple has Bromelain primarily and Papain additionally as enzymes.
Papaya has Papain primarily (and more concentrated in skin than fruit inside).
Bromelain and Papain are protein digesting enzymes.
I am certainly not any expert at all.
Because these enzymes digest protein, I am thinking that it is possible parasites would be killed, and dissolved in digestion possibly to the point they are not seen as a bodily unit.
Of course, I'm not saying it's impossible they would be seen.
I am just thinking it's possible that these 2 protein dissolving/digesting enzymes may kill and process parasites at times.
And that not seeing parasites expelled in their bodily form wouldn't mean to me they weren't being killed and expelled necessarily.
Just a thought for what it is worth.
Maybe wishful thinking... but I'd prefer annihilation to the point of DUBAR. Digested Up Beyond All Recognition.
