Avocado and Banana: Which Is Better for Potassium and Heart Health?

Power up your nutrition by discovering how “avocado and banana” compare, especially for heart healthy diets and electrolyte balance.

What Makes Potassium So Important?

Potassium is an essential mineral and electrolyte that:

• Regulates fluid balance and blood pressure
• Supports muscle contractions and nerve transmission
• Lowers risk of cardiovascular disease by offsetting sodium’s effects

Most adults need 2,600–3,400mg potassium daily, but many fall short due to low intake of fresh fruits and vegetables.

The American Heart Association recommends a potassium-rich diet to lower blood pressure and reduce stroke risk.

A study published in the Journal of the American College of Cardiology found that diets rich in potassium-laden foods like bananas were associated with a 27% lower risk of stroke.

Nutritional Showdown: Avocado vs. Banana

Let’s compare the nutritional profiles of avocado and banana, focusing on potassium:

Avocado (1 cup, 150g)

• Potassium: 708mg (~20% DV)
• Healthy fats: 21g (mostly monounsaturated oleic acid)
• Fiber: 10g
• Key vitamins: K, E, B5, B6
• Antioxidants: Lutein (beneficial for eye health)
• Carbohydrates/Sugar: Low

Banana (medium, 118g)

• Potassium: 422mg (~12% DV)
• Carbohydrates: 27g (14g natural sugar, 3g fiber)
• Key vitamins: C, B6, folate
• Antioxidants: Dopamine, catechins
• Magnesium: 8% DV

Potassium Content: Head-to-Head

Winner: Avocado, with nearly 65% more potassium per serving and higher potassium per 100g.

Heart-Healthy Benefits

Both avocado and banana support a heart-healthy diet:

• Avocado: The strong combination of potassium, fiber, and healthy fats lowers LDL cholesterol and triglycerides. It also increases HDL cholesterol.

• Banana: Eating bananas regularly can reduce the risk of stroke due to their potassium content. They can also help manage blood pressure. Magnesium and B6 assist with muscle and nervous system function.

Pro tip: Potassium helps relax blood vessels. This supports healthy blood pressure and lessens the impact of sodium intake.

Electrolyte Balance & Active Lifestyles

• Bananas are a popular choice for athletes who need quick electrolytes and energy during workouts.

• Avocados provide more potassium per serving and extra magnesium for sustained energy, making them a great option for post-exercise recovery.
