Banana

Fact: Bananas are high in potassium. If you’re on medications that raise potassium (e.g., potassium-sparing diuretics, ACE inhibitors, ARBs) or you have reduced kidney function, eating high-potassium foods like bananas can lead to hyperkalemia (too much potassium in the blood). For example, potassium-sparing drugs + a banana binge = elevated risk.
