What are potassium rich foods?
Potassium rich foods are naturally occurring foods that include vegetables, fruits, and drinks, which contain a substantially high amount of this mineral.
Classified both an alkaline mineral and an electrolyte, this essential nutrient plays an important role in maintaining the electrolyte balance in the body. It also helps your heart, nerve cells, and muscle cells to function properly.
To fully understand why you should eat these foods, read about the power of its health benefits.
The daily requirement or the recommended daily allowance (RDA) of dietary potassium for adults is 4,700 milligrams. That is the goal of how much of this mineral an adult must take per day set by the National Academy of Sciences.
But, most men and women do not consume that much of it due to an insufficient dietary intake.
Potassium supplements do help but your preference should be to get your supply of this mineral and electrolyte from foods such as vegetables, fruits, and beverages.
Benefits on blood pressure
The importance of a diet rich in potassium lies in the fact that the foods incorporated are highly recommended dietary inclusions to delay the onset of high blood pressure and also lower elevated blood pressure. At the same time, however, low sodium intake is also necessary.
A potassium-rich diet also negates the effects of salt on blood pressure, reduces the risk of developing kidney stones, and helps to decrease bone loss due to age.
Another reason to recommend natural sources of potassium is that an overdose from natural sources is nearly impossible. You can, therefore, not each too much of this mineral and electrolyte from your diet.
However, people who have a kidney problem or are on dialysis should be careful how much of these foods they consume.
You should know that too much potassium in the body, called hyperkalemia, does have its bad effects.
List of potassium rich foods including vegetables, fruits and drinks and their proportionate content
Here is the list of foods that will give you a good amount of this mineral and which also shows their potassium content. These foods also provide other nutrients such as fiber, which adds to their value.
This list is also useful for those suffering from chronic kidney disease (CKD) and who need to lower their potassium. These are the same foods they should avoid.
Such people with CKD should not consume more than 2000 mg of potassium per day.
It is highly recommended that your supply should come from food sources; fruits and vegetables form the top recommendations.
This is because they favorably promote acid-base metabolism, which reduces the risk of kidney stone formation and loss of bone density.
Some of these foods contain more potassium than the banana, which is so famous for its content of this mineral.
The current daily value for potassium is 3.5 grams
All meats (red meat and chicken)
Certain meat and animal products can help meet your needs of potassium.
However, The American Institute for Cancer Research suggests that you eat no more than 18 ounces of red meat, such as pork, beef, and lamb per week to reduce the risk of cancer.
Another precautionary measure is to eat chicken without skin to limit intake of saturated fat and calorie content.
