Yeah I know I'm actually considering trying that! I have had chronically low potassium so I thought what the heck!?
it was pretty funny, after I originally answered it I walked past a television that was on for noise and heard a commercial about a birth control pill that increases potassium. Yaz.
I'm not sure what to tell ya on this. I guess if it were me I would just stay away from bananas. Do you notice this with other high potassium foods/drinks such as orange juice or tomato juice? I have certain foods and drinks that agitate my IST and I've just learned to stay away from them even though I would LOVE to devour some chocolate from time to time! :-)
banana = potassium
google a search on the affects of potassium in the heart.
It is always wise to study the foods you eat. Check the vitamin contents and you can learn to balance them to benefit your system
