Dark spots on an overripe banana are more than just a sign of age; they indicate a significant boost in nutritional defense. Research has shown that as bananas ripen, they develop higher levels of a substance called Tumor Necrosis Factor (TNF). TNF is a cytokine, a type of protein that helps the immune system communicate and direct its efforts. This specific compound has the ability to combat abnormal cells and has been studied for its potential anti-cancer properties. While not a cure, the presence of this potent antioxidant and immune-boosting agent, along with heightened antioxidant levels, suggests that consuming very ripe bananas may contribute to a diet that supports the body's natural defenses against cellular damage and the development of diseases like cancer.
