Potassium, an essential element, is primarily responsible for regulating fluid balance . It is through the action of the kidneys that excess potassium consumed is eliminated via urine . ( 1 )
Note : This mineral also plays a key role in the functioning of our cells, in particular thanks to the sodium-potassium ATPase pump present in each cell. ( 2 )
When it comes to cardiovascular health , potassium has been observed to play a determining role. An increase in potassium intake is associated with a decrease in blood pressure , which, therefore, reduces the risk of stroke and heart pathologies . ( 3 )
In addition to its essential functions at the cellular level, potassium also offers other benefits for the overall health of the body.
It protects against age-related bone loss
Adequate potassium intake may offer protection against bone breakdown and osteoporosis (brittle bone disease) . Potassium, found naturally in many foods, including fruits and vegetables , contributes to bone health by neutralizing acids that can pull calcium from the bone and eliminate it through urine.
So, by maintaining an acid-base balance in the body, potassium helps preserve bone density and reduce the risk of fractures . Additionally, a diet rich in potassium may also promote the absorption of calcium , another essential mineral for bone health. ( 3 )
It reduces the risk of kidney stones
By incorporating a diet rich in potassium, we can potentially reduce the risk of developing kidney stones. One study showed that sodium restriction combined with increased potassium, magnesium, and citrate intake is beneficial in reducing risk factors for stone formation .
This dietary approach not only minimizes the risk factors associated with kidney stone formation, but also contributes to an overall balance of kidney health . ( 4 )
It improves muscle health
Potassium plays an essential role in the well-being and functioning of our muscles . It actively intervenes in the process of muscle contraction , ensuring that our muscles function optimally . In addition to this, an appropriate intake of potassium can be the key to avoiding discomforts like muscle cramps , which can occur when there is an imbalance of this mineral in the body.
Unfortunately, with current dietary trends favoring processed foods over fresh fruits and vegetables , many people are not getting enough potassium . This reduction in potassium intake can have direct consequences on the health and performance of our muscles . So make sure you eat a balanced diet to maintain healthy muscle function . ( 5 )
It regulates body pH
Also, it actively intervenes in the regulation of blood pH , thus guaranteeing the proper functioning of our cells and our metabolism . The delicate balance between potassium and blood pH is crucial to ensuring optimal health.
Research has shed light on the interplay between these two elements , revealing their joint importance in maintaining robust overall health. You must, therefore, ensure that you obtain a sufficient intake of potassium in order to benefit from its benefits on pH regulation and, by extension, on the health of the entire body . ( 6 )
