That doesn't surprise me whatsoever. I've been on the same regiment of 3 meds controlling my BP (beta blockers yadayada etc) for the past ten years with zero problems experienced whenever eating pineapple. All of sudden, last year, one of my prescriptions came with a strict warning to avoid eating....OMG!!!!!! I just realized that the warning I received was about combining one of my BP meds with Grapefruit...not pineapple. I'm so embarrassed, but it's a real good thing that I've never liked Grapefuit.
I suspect I'm in need of new reading glasses!
Glazed ham with pineapple and upside down pineapple cake are now back on the menu!
