Why Do We Need Potassium?
Potassium has numerous crucial functions within the body, and it plays an important role in blood pressure regulation. In this regard, numerous large studies have demonstrated that increasing potassium intake and reducing sodium intake lowers blood pressure (31, 32, 33).
Despite the importance of sufficient dietary potassium intake, hypokalemia (low serum potassium levels) is quite prevalent. According to data from the National Health and Examination Survey (NHANES), it was estimated that hypokalemia prevalence in the United States population stood at 11% in 2016 (34).
To learn more about the importance of potassium, see this guide to potassium’s beneficial functions.
Also, for anyone trying to cut down on their sodium intake, see this list of foods high in sodium for more relevant information.
How Much Potassium Do We Need?
The US Food and Drug Administration (FDA) sets a ‘daily value’ for potassium, which is a simple reference value based upon a typical 2000-calorie diet.
The daily value for potassium is 4,700 mg (35).
However, there are also ‘adequate intake’ levels that have been set, which vary by age and sex. You can find out more about adequate intake levels in this guide to potassium’s functions.
Final Thoughts
As this article shows, a diverse range of foods are high in potassium.
Consuming seafood, legumes, and fruit and vegetables like avocados, bananas, and leafy greens is one of the best ways to get more of the mineral.
