Potassium content strongly depends on sodium concentration in the blood and our organism controls the potassium-sodium balance very rigidly. Sodium prevails in the extracellular fluid, while potassium can be found mostly inside the cells. Normal metabolism depends on the balance of these two ions to a big extent.
Among the main providers of potassium are vegetables, fruits and grains. Dried apricots, melons, parsley leaves, beans, dates, strawberry, bananas, cottage cheese and cheese are especially rich in potassium.
In our organism potassium relates to carbohydrate metabolism. Obese people always lack it. Deficiency of potassium also leads to heart and nerve conduction disorders. Excess of sodium can also become a reason for such diseases, as the balance of these two elements is disturbed in both cases.
It is thought that a person needs around 3 grams of potassium per day. You do not need to count these grams every day, of course, as natural products contain much more potassium than sodium. Because of that, nature created a way of its effective removal. Excess of potassium causes intensified urinary flow and easily leaves your body with the urine. Unnecessary sodium is removed at the same time. If there is not enough sodium in the organism, it is absorbed again in the kidneys and just potassium is released. Therefore, you can eat products rich in potassium without any worries, they will only do you good. Their consumption is even prescribed during edemas, obesity and heart and blood vessel diseases.
