Potassium
Potassium is an important nutrient that plays a role in normal body functions. This guide explains what it does, common food sources, what can affect intake, and how tracking your diet can help you understand your overall nutrient intake.
Recommended intake varies by age, sex, and life stage. Tracking what you actually eat can help you understand your overall dietary intake over time.
What Potassium does
Potassium plays a role in:
- supporting normal heart function
- helping muscles contract normally
- supporting nerve transmission
- contributing to normal fluid balance and cell function
Potassium intake
Intake targets vary across life stages. Age, sex, eating patterns, food variety, and day-to-day routines can all influence how much potassium appears in a person’s diet.
Tracking can help you compare your usual food pattern with the foods that commonly provide potassium.
Common food sources of Potassium
Food sources of Potassium may include:
- bananas, oranges, and dried apricots
- potatoes, tomatoes, spinach, and broccoli
- beans, lentils, and soy foods
- milk and yogurt
- fish, meat, and poultry
The amount can vary depending on the food, serving size, preparation method, and brand.
What can affect Potassium intake
A person’s intake may vary due to factors such as:
- food preferences and usual food choices
- restricted diets or low intake of fruit, vegetables, or legumes
- appetite changes or small meal sizes
- digestive tolerance and limited food variety
- lifestyle habits and meal routines
Why intake may be lower in some people
Some people may find it harder to get enough Potassium from food alone because of:
- low intake of fruits, vegetables, legumes, dairy, or fish
- limited meal variety over time
- poor tolerance of some common potassium food sources
- changing appetite or eating patterns
Dietary intake can vary a lot from one person to another. This page is about food intake and tracking, not diagnosis or treatment.
