Importance of Potassium

Potassium is a mineral that helps regulate fluid balance, muscle contractions, and nerve function. It also plays a role in maintaining a healthy heart and blood pressure. Adequate potassium intake can help prevent high blood pressure, stroke, and kidney stones.

Recommended Potassium Intake

The recommended daily intake of potassium for adults is 2,500-3,000 mg. However, this can vary depending on age, sex, and health status. People with kidney disease, for example, may need to limit their potassium intake to avoid complications.

High Potassium Foods to Avoid

Foods that are high in potassium include bananas, oranges, tomatoes, potatoes, avocados, spinach, and beans. While these foods are nutritious, they should be limited or avoided on a low potassium diet.

Low Potassium Foods to Eat

On a low potassium diet, it's important to focus on foods that are low in potassium but still provide necessary nutrients. Some examples of low potassium foods include apples, berries, pineapple, cauliflower, broccoli, chicken, and fish.
