10 Potassium-Rich Foods to Support Healthy Blood Pressure

High blood pressure affects millions of people worldwide. Diet plays a major role in keeping it under control.

Most people focus only on cutting salt. But boosting potassium may matter just as much for healthy blood pressure.

Potassium helps balance sodium levels in the body. It also helps blood vessels relax, which supports lower blood pressure naturally.

This guide covers ten powerful potassium-rich foods. You will also learn how much potassium you need and how to add these foods to your daily meals.

Why Potassium Matters for Blood Pressure

Potassium is a mineral that plays a key role in heart health. It works alongside sodium to control fluid balance in the body.

How Potassium Supports Healthy Blood Pressure

• Helps the body remove excess sodium through urine
• Supports relaxation of blood vessel walls
• Reduces strain on the heart over time
• Balances the sodium-to-potassium ratio in the diet

Research shows the sodium-to-potassium ratio predicts heart health better than sodium alone. This makes potassium an essential part of any blood pressure plan.

How Much Potassium Do You Need?

Most health experts recommend 3,500 to 5,000 mg of potassium daily. Unfortunately, most people fall far short of this target.

Whole foods remain the safest and most effective way to reach this goal. The ten foods below offer some of the richest potassium sources available.

1. Baked Potatoes (With Skin)

Baked potatoes rank among the richest potassium sources in a typical diet. A single medium potato with skin offers around 919 mg of potassium.

Why Baked Potatoes Support Blood Pressure
