Connection Between Potassium Deficiency and High Blood Pressure


Most people know that high sodium contributes to high blood pressure (hypertension), but did you know that low potassium can also contribute to high pressure? Potassium blunts the effects of sodium and helps the body to normalize blood pressure.

"Scientists began studying the effects of potassium on high pressure as early as 1928. Now a major study of 300 nurses shows that potassium can lower your pressure even if it's in the normal range. Good sources of potassium are dried apricots, avocados, dried figs, acorn squash, baked potatoes, kidney beans, cantaloupe, citrus fruits, and bananas. You can also buy potassium supplements. If you're taking a diuretic, your body is getting rid of potassium along with fluid." Frank K. Wood says "When it comes to lowering blood pressure, potassium packs a powerful punch," in Natural Cures and Gentle Medicines That Work Better Than Dangerous Drugs or Risky Surgery.

"Low potassium is a major cause of cardiac arrhythmia; diuretics for the treatment of high pressure or congestive heart failure may interfere with potassium absorption and excretion. Although potassium supplementation is usually not necessary, individuals on diuretics or laxatives or who have excessive diarrhea may require extra potassium." Dr. Stephen T. Sinatra, MD, in A Cardiologist's Prescription for Optimum Health explains "Since potassium is necessary to the healthy functioning of nerves, cells, and membranes, it is an important electrolyte to monitor,"

In the New Encyclopedia of Vitamins, Minerals, Supplements and Herbs, Nicola Reavley also points out the important role of potassium in controlling high blood pressure: "Many population studies have found links between low potassium intakes and an increased risk of high pressure and death from stroke. Increasing the amount of potassium-rich foods in the diet can lead to a reduction in high blood pressure. The ratio of sodium to potassium in the diet appears to play an important role in the development of high blood pressure. The typical Western diet is low in potassium relative to sodium."

The best way to get more potassium in your diet is to eat more potassium-rich foods such as apples, apricots, bananas, broccoli, carrots, lima beans, oranges, potatoes, prunes, spinach, squash, and watermelon.

It is always better to avoid processed food that are rich in sodium while eating fruits and vegetables. It seems foods that contain high potassium is suppose to be vegetables and fruits. A large amount of sodium can be found in a can of soup. It is always advised to read food labels.

Blood pressure can be lowered naturally by eating more fruits and vegetables and less processed food. Increasing the intake of fiber and reducing the food based on fat and cholesterol will also lower your pressure.

People who have high pressure should follow a regular exercise routine. Alternatively you can start a simple exercise program in your home. You need not to hit gym. This will actually lower pressure.

Foods That Fight Iron Deficiency


Anemia is one of the most common disorders in young people and children today.  Anemia, in common terms, iron deficiency, is caused by a lack of red blood cells or hemoglobin, in the blood.  When these hemoglobin cells are lacking oxygen, fatigue, dizziness and a lack of stamina might be the result.  In cases of severe anemia you might suffer from shortness of breath, or even heart problems.  This is why it is vital for young people to have a sufficient amount of iron in their bodies at all times.

The most common type of anemia is iron-deficiency anemia.  One of its main causes is a reduced production of red blood cells which often leads to a deficiency in nutrients and oxygen to the blood.  The problem with iron deficiency is that our bodies take a long time to replenish iron, and if it is not a staple in our regular diet it may take years to reach healthy iron levels.  Having low iron levels may lead to more serious problems like malnutrition because of a poor diet, and lack of vital nutrients and minerals.  Children are far more susceptible to iron deficiency because of their growing bodies, and sometimes their poor diets.  This is why feeding your children foods which are rich in iron is as important as ever.

To counteract iron deficiency a diet of more iron rich foods is absolutely necessary.  Iron rich foods will increase iron in the blood, which will lead to better absorption in the tissues.  The most common forms of iron we digest are iron from meat sources and iron absorbed from plant sources.  Meats have an excellent amount of available iron, and provide the necessary amount to sustain proper iron levels.  Iron from meat sources is more easily absorbed than that obtained from plants.  Also calcium and vitamin C can increase your iron levels, as they help the body absorb iron better.

One of the best sources of iron is raisins.  One cup of raisins alone contains almost 5 milligrams of iron, which is outstanding.  Raisins are also rich in potassium and high in electrolytes as well.  People who live in colder climates like Aspen use a lot of raisins in their food to supplement for the lack of natural iron in their diets.  Spinach is also a great source of iron.  Spinach is filled with high iron levels and vitamin C. It is also an excellent source of potassium.  Other foods that are high in iron are foods like cereals, oatmeal, as well as dried fruits such as apricots and peaches.  Pasta can be a good source of iron as well as carbohydrates. 

It is important to choose the right foods for your diet that are not only desirable, but vital to the body as well.  Feeding your kids in Aspen, LA, or anywhere in the country, high amounts of iron will help their bodies to grow and sustain them well into adulthood.  If you are an adult and have a low iron diet, it is time you rethink what you have been eating and start trying more iron rich foods today.

Potassium Deficiency in the Elderly


If you are suffering from potassium deficiency, it is medically referred to as hypokalemia. This deficiency occurs when the levels of potassium drops in the blood. This deficiency can cause a lot of health problems as potassium is an important element for proper working of the nervous system. In addition, potassium is also required for the working of muscles and proper functioning of the heart.

As a person ages, their food intake decreases. This leads to deficiency of several vitamins and minerals, including potassium. If a senior is suffering from deficiency of potassium the following symptoms will be seen:

• Fatigue

• Weakness of the muscles

• Cramps in the legs

• Skin rash

• Insomnia

• Mood swings

• Depression

• High levels of blood sugar

• Slow and irregular heartbeat

• Arrhythmia

• Weak bones

The main cause of deficiency of potassium in seniors is their diet. Many seniors use diuretics and this leads to salt and water from the blood being eliminated out of the body via urination. Diuretics are usually prescribed to seniors who are suffering from elevated blood pressure, liver diseases, heart failure and kidney diseases. Diuretics like thiazide and furosemide are prescribed to seniors and these two medications can lead to deficiency of potassium. However, seniors can also suffer from low levels of potassium in the body due to gastrointestinal infections that cause diarrhea and vomiting, or using too much laxative.

Usually when a senior is suspected of suffering from hypokalemia, a blood test is done to confirm the diagnosis. At times the urine can also be tested to check the presence of potassium. If a senior is diagnosed with hypokalemia, he or she needs immediate medical help. The doctor will intravenously give the person potassium supplements if the condition is several. Alternatively, the person may be asked to tablets of the supplement if the deficiency is mild to moderate. In addition, the person will be asked to consume a potassium-rich diet. Foods like tomatoes, banana, milk, potatoes and figs are rich source of potassium.

Potassium, Deficiency and Potassium Rich Food


Potassium represents 5% percent of the total mineral content of a human body, even though only about one litre is found in the body at a time. Potassium is found in our bodies both inside and outside cells and is a very important mineral required every day to stay healthy. More than 98% of the body's potassium is intracellular. The body easily absorbs potassium, but nearly 90% of it is excreted through the kidneys and bowels. Thus, potassium is a natural diuretic and is important for the elimination of body wastes, such as water and sodium.

Potassium is a primary electrolyte, it is a great alkalizer, and important for maintaining pH and water balance.

Benefits of potassium:

1. Along with other minerals such as sodium, chloride and calcium, potassium helps in normal cellular function, such as transmission of nerve impulses, digestion, healthy muscle contractions, proper cardiovascular functioning (heartbeat irregularities are normally a sign of potassium deficiency), and helping the body to convert glucose into glycogen (the body's stored form of energy).

2. Potassium helps promote healthy cardiovascular health. It is strongly believed that potassium has the ability to pump sodium out of the body's cells and reduce body fluid.

3. Potassium, along with sodium, helps to regulate blood pressure. Increasing potassium in the diet may protect against hypertension in people who are sensitive to high levels of sodium.

4. Potassium also affects blood vessel tone as well as the way blood vessels react to the flowing hormones, thus affecting pressure within blood vessels.

5. Potassium therapeutically assists in the treatment of alcoholism, acne, alleviating allergies, promoting the early healing of burns.

6. It also helps with problems such as congestive heart failure, chronic fatigue syndrome or kidney stones.

7. Potassium plays a vital role in cellular integrity by regulating the transfer of nutrients into the cell.

8. Potassium also attracts oxygen to tissues, helps correct positioning of vital organs. Potassium deficiency indicates that probably albumin, sugar, sodium, and chlorine are also in short supply or not being properly absorbed.

9. Potassium helps proper functioning of the adrenal glands. It helps support healthy sugar balance in the body.

Deficiency of potassium -

The kidneys excrete excess potassium from the body, and deficiencies are rarely found in people on a normal balanced diet. A deficiency may result in fatigue, cramping legs, muscle weakness, sluggish reflexes, acne, dry skin, mood swings and irregular heartbeat.

A shortage of potassium in body may cause a fatal condition known as hypokalemia, resulting from diarrhoea, increased diuresis and vomiting. Hypokalemia can occur in people with a chronic disease or due to ageing process. Deficiency symptoms include muscle weakness, ECG abnormalities, decreased reflex response, congestive heart failure, cardiac arrhythmia and respiratory paralysis.

If the fluid and electrolyte balance is not restored, the risk of heart failure increases.

Potassium deficiency increases acid levels in the body, lowers the natural pH balance, causes problems with the formation of connective tissue. Kidney diseases (such as acute renal failure), diabetes can also cause fluctuations in the levels of potassium. Many medications such as diuretics, cortisone, prolonged use of aspirin, and laxatives also cause depletion of potassium.

Dietary sources of potassium:

Eating a variety of foods that contain potassium is the best way to get the required amount. Individuals who eat a balanced diet do not need potassium supplements. Foods, which are rich sources of potassium include turnips, whole grains, molasses, fish, citrus fruit, apple cider vinegar, bananas, avocados, yoghurt, tomatoes, poultry, oranges, apricots, potatoes (especially their skins), leafy green vegetables such as spinach, lettuce; and meat. One large orange will supply one with 250 mg of potassium, one-eighth of a person's daily need. Dried apricots contain more potassium than fresh apricots.

Steaming of foods helps to retain nutrients that are lost through other cooking techniques such as boiling (loss of about 50% of potassium content). Steaming results in only a 6% loss of potassium.

Recommended Daily Allowance of potassium:

There is no recommended daily allowance (RDA) for potassium, but it is advised to get between 2,000-3,000 mg per day. The range of intake for children is 780 to 1,600 mg per day.

This is not difficult, and most people meet this requirement on their own through a normal diet. In general, nutritionists recommend reducing salt intake and ensuring adequate supply by increasing the amount of fresh fruit and vegetables in the diet.

If one is into bodybuilding, he must increase the potassium intake, since potassium is needed to maintain muscles in good form, and also because potassium is lost from excessive sweating and urine.

Symptoms of high intake of potassium:

Excessive potassium can be toxic and will affect the heart. This is a problem especially when one is suffering from some problem such as kidney failure. Irregular heart beat and muscle fatigue is sign of toxic potassium levels. In healthy people, the kidneys in the urine excrete excess potassium.

Who requires extra potassium?

People who require potassium supplements include:

- women on oral contraceptives,

- chronic alcoholics or drug abusers,

- smokers

- people undergoing stress

- athletes

- people doing strenuous exertion,

- anyone suffering from any degree of mal-absorption syndrome

- people with eating disorders, especially bulimia and anorexia..
