4. It lowers iron absorption

This can be particularly dangerous for people with an iron deficiency. When an individual with an iron deficiency consumes bananas on an empty stomach, it can cause significant harm. Bananas are filled with potassium, which can prevent the absorption of iron.

5. It causes acidity

If you have GERD or heartburn and haven’t eaten anything else, avoid eating bananas! Consuming bananas without any other food can cause your body to become acidic, as bananas are naturally acidic. While they might initially boost your energy, they can leave you feeling fatigued and lead to stomach issues.
