Potassium is a vital mineral that supports fluid balance, muscle contractions, and nerve signals.
Sufficient intake is linked to lower blood pressure, reduced stroke risk, and prevention of osteoporosis and kidney stones. Ensuring enough potassium in the diet is key for overall well-being.
Bananas as a Potassium Source
Bananas are well-known for their potassium content—one medium banana offers around 422 mg. They also provide fiber, vitamin C, vitamin B6, and antioxidants, supporting heart health, digestion, and steady energy levels. Their portability makes them a convenient snack choice.
Daily Potassium Needs
For adults, the Adequate Intake (AI) level is 2,600 mg per day for women and 3,400 mg for men. Most people fall short of these targets, making potassium-rich foods important in the diet.
While potassium is essential, too much can cause hyperkalemia—dangerously high potassium levels in the blood. Symptoms include muscle weakness, fatigue, irregular heartbeat, and, in severe cases, can be life-threatening. People with kidney disease, those on certain medications, or individuals with impaired potassium excretion are at higher risk.
