1. Bananas: Everyday Heart Support

Bananas are one of the most accessible potassium-rich fruits. Potassium helps relax blood vessel walls, improving blood flow and reducing high blood pressure—one of the leading risk factors for heart disease. Bananas are also gentle on digestion and easy to include daily.
How to eat: As a snack, in smoothies, or with oatmeal.

2. Sweet Potatoes: Blood Pressure Friendly

Sweet potatoes are packed with potassium, fibre, and antioxidants. Potassium helps flush excess sodium from the body, easing pressure on the heart and kidneys. The fibre also supports stable blood sugar levels, which indirectly benefits kidney health.
How to eat: Boiled, roasted, or mashed with minimal salt.

3. Spinach: Mineral-Rich Leafy Green

Spinach provides potassium along with magnesium and nitrates, which support healthy blood vessels and circulation. It also helps reduce oxidative stress that can affect kidney function over time.
How to eat: Lightly sautéed, added to dal, soups, or smoothies.

4. Avocado: Healthy Fats + Potassium

Avocados combine potassium with heart-healthy monounsaturated fats. This combination supports cholesterol balance and helps reduce inflammation in blood vessels. Potassium in avocado also supports fluid balance, easing kidney workload.
How to eat: Sliced on toast, in salads, or blended into dips.

5. White Beans: Kidney-Friendly Protein Source

White beans are rich in potassium, plant protein, and fibre. They support heart health by helping lower LDL cholesterol and stabilise blood pressure. When consumed in moderate portions, they are also beneficial for kidney health due to their slow-digesting carbohydrates.
How to eat: In soups, curries, or salads.

6. Coconut Water: Natural Electrolyte Booster

Coconut water is a natural source of potassium and electrolytes that support hydration and heart rhythm. Proper hydration helps kidneys flush toxins efficiently while potassium supports healthy blood pressure levels.
How to drink: Plain, unsweetened, in moderation.

How Much Potassium Is Enough?

Most adults need around 2,600–3,400 mg of potassium daily, depending on age and gender. The best way to meet this need is through whole foods rather than supplements, unless advised by a doctor.
