As soon as I see the stringy substance appear in my banana, I try to avoid it at all costs! However, this unidentified object has been identified as "phloem bundles". WHAT?
This fibrous, icky growth is necessary for us and eating it will add more nutrients to our diet including sugar and other metabolic products. That's okay, I'll still avoid it at all costs! Similar to the end pieces from a loaf of bread!
