Did you know that the little strings on bananas have a specific purpose? Let’s dive into the science behind these often-annoying phloem bundles and discover why they are more than just an inconvenience.
Unveiling Phloem Bundles: When you peel a banana’s yellow skin, these strings are exposed, and they can be a bit pesky to remove. They run vertically along the fruit and are more tenacious on less ripe bananas, while they hang loosely on ripe ones. But what exactly are they? These are known as “phloem bundles,” which serve a crucial role in a plant’s life.
The Role of Phloem: Phloem bundles are responsible for transporting nutrients from the leaves to the fruit, playing a vital role in the plant’s growth and overall health. Therefore, these strings are not just a part of the banana itself – they are fully edible!
They’re Edible and Nutritious: Contrary to their lackluster taste, phloem bundles are surprisingly healthy. While they may not contribute directly to the banana’s flavor, they are packed with essential nutrients such as potassium, fiber, vitamin A, and vitamin B6. Even after the banana is harvested, these vitamins remain in the phloem, making them a valuable part of the fruit.
Benefits of Overripe Bananas: Interestingly, bananas with brown spots, often considered overripe, are even more nutritious. They have been found to offer numerous health benefits:
- Lower your risk of developing cancer, thanks to a component that can combat cancer cells.
- Help control your blood pressure, as overripe bananas are rich in potassium, which promotes stable blood pressure.
So, the next time you encounter those pesky banana strings, remember that they are not just an inconvenience but a part of the banana’s nutrient-rich makeup.
