The black dots or "balls" in bananas are usually undeveloped, sterile seeds or remnants of the vascular bundles (phloem) that transport nutrients, while the black nub at the end is the withered banana flower, all generally harmless but sometimes indicate over-ripeness or spoilage if mushy or smelly.
Banana seed remnants blacken first
Wild bananas have black seeds, about the size of a bean, Brecht said. While our supermarket bananas are, of course, seedless, tiny bits of would-be seeds remain. In a stressed banana like this, those areas where the seeds would have been tend to turn brown and black first.
7. Antioxidant Powerhouse Ripe bananas with black spots are rich in antioxidants, including dopamine and catechins. These compounds play a significant role in reducing oxidative stress, which can damage cells and accelerate aging.
Yes! As long as there's no mold and they aren't fully black or mushy, they're completely safe and even healthier than underripe bananas. Are they too sugary? They're sweeter—but with natural sugars balanced by fiber.
That little black nub, on the other hand, well that's always there. That's because it's not a seed, but the flower from which your giant banana berry grew. Bananas grow on trees in bunches, and the stubby end is actually the “top” of the fruit while the hard stalk is the “bottom”.
Why Fruit Flies Are On Banana Skins. Apparently, fruit flies lay their eggs on the skins of bananas, so we ultimately end up bringing them home with us from the grocery store.
If they smell off, that's another good indicator that they are no longer okay to use. Rotten bananas will often have a fermented or alcohol-like smell. While it's okay if the banana peel is dark brown or even black, if the inside is too, then the fruit is beyond ripe and now on its way to rotten.
Those big black seeds were the original seed of the banana. They're the seed that the tree would spread.
The roots and leaves of the banana plants are the only parts that are not consumed as food by humans. - The banana plants belong to the genus Musa, having a large herbaceous habit.
Even if bananas have a few brown spots on the skin or the flesh, they are still definitely edible. The brown parts can simply be cut off. Alternatively, very ripe bananas also make great smoothies or homemade banana ice cream.
There are no reports suggesting the harmful effect of eating bananas infected by Nigrospora spp.

Signs of Spoilage in Bananas
If your bananas have any of these signs of spoilage, it's time to toss them: A strong fermented or sour smell. Liquid leaking from the peel. Large dark brown or black patches.
You can just take a bite and then spit out the seeds if desired. They aren't typically eaten raw like the common banana, but you certainly can if you wish. Lots of times they are used in smoothies, ice cream, baked goods like banana bread, and in Java, they are used in a popular dish called Rujak.
Digestive health
Bananas contain a type of fiber called pectin, which can play a part in controlling how quickly you digest carbohydrates. Bananas may be good for your tummy, too. They have probiotics, which are the good bacteria found in your gut, and prebiotics, carbs that feed these good bacteria.
Generally, experts don't recommend that you eat a banana on an empty stomach because it might mess with your blood sugar levels.
Banana seeds and strings
In commercial bananas, you will see small black specks. These are ovules, the vestiges of seeds that would have developed, had the banana plants not been sterile. Wild bananas left to their own devices develop larger and harder seeds with less flesh around them.
The black skin itself is not mold. Mold on bananas is fuzzy white, gray, or greenish—it looks a lot like mold on bread. If a banana smells rotten or fermented or is leaking fluid, it's time to say goodbye. If the fruit inside, not just the peel, is black, that's a sign that your banana is too far gone to safely eat.
You're Sensitive to FODMAPs
Ripe bananas contain FODMAPs, rapidly fermented sugars that can cause excess gas and lead to symptoms like bloating, cramping, and diarrhea or constipation for some people with conditions like irritable bowel syndrome (IBS).
The Wrap-Up. Overripe bananas may not be the prettiest fruits, but they're still full of nutrition. The ripening process increases their natural sugars, making them ideal for banana-flavored desserts, and their extra antioxidants may help reduce inflammation. So don't toss those browning 'nanners!
Eating these flies or their eggs is not dangerous for human health. Fruit flies are not disease vectors. They do not transmit infectious agents by bites or stings. However, they can transmit bacteria by the wounds their ovipositors open in fruits, which can cause disease when humans eat the infected fruit.
Bananas should be stored on the kitchen counter until they ripen, then refrigerated to keep them fresh for longer. Putting bananas in the fridge too soon can cause chilling injury, leading to bitterness and discoloration. Separating bananas and covering their stems with plastic wrap can help keep them fresh longer.
