Tag: Phloem bundles

Those little stringy bits on a banana are scientifically known as phloem bundles, the plant's vascular tissue for transporting nutrients and water during growth. If you've ever wondered why does my banana have a hard string in the middle, you're not alone, and the simple explanation is rooted in the fruit's biology.

According to a 2019 study, banana peels consist of 71% to 83% fiber, suggesting a significant portion of the fruit is often discarded. This fact raises a crucial question for eco-conscious and health-minded individuals: are you supposed to eat a whole banana, peel and all?

The stringy bits on a banana, officially known as phloem bundles, are completely safe and edible. Many people peel them away out of habit, believing them to be unappetizing or useless, but they serve an important biological function and contain nutritional value similar to the fruit's flesh.
