For the normal functioning of our organism with necessary micro - and macronutrients we get from food. One of the important macronutrients is potassium. A lack of potassium (hypokalemia) can lead to a rather unpleasant health problems.

Potassium necessary for normal functioning of soft tissue just as calcium is needed for bones and other hard tissues. Potassium is a part of all intracellular liquids. Very important potassium to maintain normal intracellular pressure. and he does it in conjunction with sodium: put simply, the potassium acts on the inner walls of the cells, and sodium — on the outside. Adherence to the sodium-potassium balance is important for maintaining the normal functioning of nerves and muscles (including heart muscle), and also for the normalization of water balance.

Also potassium in the body is associated with magnesium. it supports the concentration of magnesium and helps him to perform a physiological function (magnesium is necessary for normal synthesis of protein). Usually a lack of potassium in the body accompanied by lack of magnesium.

A potassium deficiency is usually manifested in fatigue, weakness in legs, muscle pain. In severe cases may experience more serious symptoms (paresis of the muscles, respiratory disorders). Low potassium levels increases the risk of cardiovascular diseases and other health problems.

Why is there a lack of potassium? The obvious answer: because we are not getting enough of this macronutrient in the diet. But this answer is correct only partly. Usually our body is able to cope with the fact that we do not get enough potassium from food, unless we are not talking about a hard diet. A potassium deficiency may occur if insufficient intake of potassium with food combined with too intense removing it from the body .

Increased body's need for potassium is observed with vomiting, band, heavy sweating, use of diuretics. potassium comes from the body of liquid. Therefore, in hot seasons and in certain diseases the body's need for potassium increases, and if you do not consume enough calcium-rich foods, can develop a potassium deficiency.

A potassium deficiency can be caused physical strain, emotional stress, alcohol, coffee and sweets in large quantities, taking diuretics, debilitating diets, and a number of illnesses, from hypoglycemia to kidney problems.

If you are constantly tired, maybe the cause is not lack of sleep, and lack of potassium in the body. In this case you need to contact the doctor he will determine whether you have hypokalemia, and not some other disease. Perhaps he will advise you to take potassium supplements, but in most instances deficiency of potassium helps to fight the inclusion in the diet of potassium-rich foods.

A lot of potassium in fruits and in green vegetables. Of course, the most famous fruit boasts a high content of potassium is bananas. But this is not the only source of potassium for our body. A lot of potassium in melon, dried fruits, kiwi, avocado, citrus, grapes, broccoli, sweet potatoes, potatoes, beans, spinach, cucumbers, carrots, parsley, asparagus, horseradish, garlic, black currants, cabbage, radishes, tomatoes. Also potassium is in fish, liver, dairy products, chocolate, peanut butter, rye bread, oats and millet cereal.

However, it is not enough to just use these foods: potassium should be absorbed.Potassium promotes the absorption of vitamin B6, but alcohol impedes this process. In any case, not voluntarily, without a doctor's prescription to take potassium supplements: an overabundance of calcium in the body (hyperkalemia) is not less dangerous to health than the lack of it.

Balanced diet and a healthy lifestyle will help prevent a lack of potassium in the body. But if you still suspect that your body is not enough potassium, before eating the bananas, be sure to consult your doctor and give blood for analysis. to make sure that your suspicions are correct.
