The Relationships Between Salt & Potassium | Healthy Eating | SF Gate
The minerals sodium and potassium work together to balance the fluids in your body. of potassium-rich foods can lead to a buildup of sodium levels in your The lower number is advised, in particular, for those who already. Your sodium-potassium balance has major implications for your health. If potassium levels fall too low, the kidneys struggle to hold onto it, which study evaluated the relationship between sodium-potassium ratio and. There is a strong relationship between consuming too much sodium and Consuming high amounts of sodium and low amounts of potassium.
Most excess potassium is eliminated in the urine; some is eliminated in the sweat. When we perspire a great deal, we should replace our fluids with orange juice or vegetable juice containing potassium rather than just taking salt tablets. The kidneys are the chief regulators of our body potassium, keeping the blood levels steady even with wide variation in intake.
The adrenal hormone aldosterone stimulates elimination of potassium by the kidneys. Alcohol, coffee and caffeine drinkssugar, and diuretic drugs, however, cause potassium losses and can contribute to lowering the blood potassium. This mineral is also lost with vomiting and diarrhea. Potassium is found in a wide range of foods. Many fruits and vegetables are high in potassium and low in sodium and, as discussed, help prevent hypertension.

Most of the potassium is lost when processing or canning foods, while less is lost from frozen fruits or vegetables. Leafy green vegetables such as spinach, parsley, and lettuce, as well as broccoli, peas, lima beans, tomatoes, and potatoes, especially the skins, all have significant levels of potassium. Fruits that contain this mineral include oranges and other citrus fruits, bananas, apples, avocados, raisins, and apricots, particularly dried.
Whole grains, wheat germ, seeds, and nuts are high-potassium foods. Fish such as flounder, salmon, sardines, and cod are rich in potassium, and many meat foods contain even more potassium than sodium, although they often have additional sodium added as salt. Potassium may also be obtained from the following herbs: Caffeine and tobacco reduce the absorption of potassium. People at risk for insufficient potassium intake include alcoholics, drug addicts and crash dieters.
Potassium is very important in the human body. Along with sodium, it regulates the water balance and the acid-base balance in the blood and tissues.
Potassium and sodium out of balance - Harvard Health
Potassium enters the cell more readily than does sodium and instigates the brief sodium-potassium exchange across the cell membranes. In the nerve cells, this sodium-potassium flux generates the electrical potential that aids the conduction of nerve impulses.
When potassium leaves the cell, it changes the membrane potential and allows the nerve impulse to progress. This electrical potential gradient, created by the "sodium-potassium pump," helps generate muscle contractions and regulates the heartbeat. Another of the pump's most important functions is preventing the swelling of cells. If sodium is not pumped out, water accumulates within the cell causing it to swell and ultimately burst. Potassium is very important in cellular biochemical reactions and energy metabolism; it participates in the synthesis of protein from amino acids in the cell.
Potassium also functions in carbohydrate metabolism; it is active in glycogen and glucose metabolism, converting glucose to glycogen that can be stored in the liver for future energy. Potassium is important for normal growth and for building muscle.
Though sodium is readily conserved by the body, there is no effective method for potassium conservation. Even when a potassium shortage exists, the kidneys continue to excrete it. Because the human body relies on potassium balance for a regularly contracting heart and a healthy nervous system, it is essential to strive for this electrolyte's balance.
Role of Potassium in Maintaining Health
In medicine, potassium is one of the most commonly prescribed minerals. It is also commonly measured in biochemical testing and is supplemented if it is low.
How to Treat Low Potassium Maintaining your potassium levels is not difficult if you keep an eye on your diet. Foods high in potassium include avocados, beans, dark green leafy vegetables, potatoes and tomatoes. The best way to keep things in balance on a daily basis is to eat a food high in potassium whenever you eat a food that is high in salt.
Pairing potato salad with fried chicken is not only delicious, it is effective in maintaining your electrolyte balance. If you have bacon or sausage for breakfast, also have a few thick tomato slices, either raw or grilled, or toss a healthy handful of spinach into your omelette or scrambled eggs. Preventing Sodium and Potassium Deficiencies The key to keeping your electrolytes in balance is to stay hydrated without overdoing it.
After exercise, while ill, after surgery or when living in or visiting an extremely hot climate, it's best to drink only as much water as you're thirsty for.
When eating water-rich foods such as cucumbers or watermelon, add a scant sprinkle of real sea salt. This not only helps keep your electrolytes in balance, it brings out the natural flavors of the foods. Scatter a bit of chili powder on your cucumber along with the sea salt for an added savory kick. If hypokalemia lasts for an extended time, kidney problems may develop, causing the person to urinate frequently and drink large amounts of water. Diagnosis Measurement of potassium level in the blood Electrocardiography Sometimes measurement of amount of potassium in urine The diagnosis is made by measuring a low potassium level in the blood.
Doctors then try to identify what is causing the potassium level to decrease.
If the cause is not clear, doctors measure how much potassium is excreted in urine to determine whether excess excretion is the cause. Because low potassium levels can cause abnormal heart rhythms, doctors usually do electrocardiography ECG to check for abnormal heart rhythms.
Treatment Potassium supplements If a disorder is causing hypokalemia, it is treated. Usually, potassium can be replaced by taking potassium supplements by mouth.
