I'm a former athlete, used to play basketball, ate a lot of bananas.
They keep you feeling strong, healthy, invigorated, etc and we all
used to eat a lot of them before practices and games. Now, I was
always told that a big reason for this pick-me-up was because they
contain potassium. But recently, this triathlete I know was telling me
that that's a myth, that bananas actually contain absolutely no
potassium whatsoever by the time you buy them from a store. Only if
you pluck them straight off a tree do you get any potassium. So, is
she right? Is the notion of bananas containing potassium a myth?
