I don't know, I found it right away, yes the heating of it can cause less bromelain, but it will not destroy all of it. Also, my OB suggested canned, so I'm going by a medical professionals advice, not just google. Also, walking wasn't what put me into labor, I had been walking for weeks before that and it did nothing, evidently, I was at 0cms that morning, then after I ate canned pineapple, I went into labor, so did my cousin, so, it apparently works for some people!
I'm due in 5 days and have no sign of labor, I will definitely buy pineapples though
I heard eating licorice candy and rubbing your ankles in a circular motion while you eat all those foods pineapple, spicy food and the candy and I even heard doing a few jumping jacks help too
My wife is 19 weeks pregnant and I downloaded this sight to keep informed. She loves pineapple and eats it all the time. It can't effect her being 20 wks could it?
