Some important elements in the body called electrolytes or ions take part in many vital processes. They play key roles in nerve signals, keeping the body hydrated, and regulating pH balance.
Because of this, the body needs enough electrolytes from daily food to keep working well. This article will explain electrolytes in detail, their importance, and where to get them.
What are electrolytes?
Electrolytes or ions are elements that carry positive or negative electric charges. They are also known as dissolved ions.
In nutrition, electrolytes refer to essential minerals found in body fluids like blood, sweat, and urine. When these minerals dissolve, they become positively or negatively charged ions, called electrolytes, which help many vital body functions.
Electrolytes in the body include the following:-
The importance of electrolytes
The body needs electrolytes urgently and importantly for many different vital processes. They are necessary for these functions:
1. Nervous system function
The brain sends electrical signals through nerve cells to communicate with all other cells in the body. This is called nerve impulses, and these impulses happen because of changes in the electrical charges of the nerve cell membranes.
These changes happen because sodium electrolytes move through the nerve cell membrane. When this happens, it triggers a chain of reactions making more sodium ions move along the nerve cell's axis.
2. Muscle function
The body needs calcium electrolytes for muscle contraction. These electrolytes let muscle fibers slide and move over each other when muscles contract.
On the other hand, the body needs magnesium electrolytes so the muscle fibers can slide outward, helping the muscles to relax (stretch) after contracting.
3. Body hydration function
You need to keep the right amounts of water inside and outside your body cells. Electrolytes maintain fluid balance through something called osmotic pressure.
Osmotic pressure is when water moves through the cell wall from a diluted area with lots of water and fewer electrolytes to a dense area with less water and more electrolytes.
This process helps keep cells from getting too full of fluid or from drying out.
4. pH regulation function
The body needs to keep its internal pH balanced to work well. pH is a measure of how acidic or alkaline something is, and electrolytes help control it. This reduces big changes inside the body.
For example, blood pH is kept between 7.35 and 7.45. If it changes, the body can't function properly. So electrolytes are key to managing blood pH.
Food sources of electrolytes
The best way to get enough electrolytes is through a balanced, healthy diet. This helps keep your electrolytes balanced in your body.
Food sources to get electrolytes can include:-
-
Sodium:- from pickled foods andcheeses and table salt.
-
Chloride:- table salt.
-
Potassium:- fruits and vegetablesLike Bananas andAvocado andSweet potatoes.
-
Magnesium:- Seeds and nuts.
-
Calcium:- Dairy products and Dairy alternatives fortified and dark leafy vegetables.
-
Bicarbonate:- It is naturally produced in the body.
Electrolyte imbalance in the body
Sometimes electrolyte levels in the blood can be too low or too high, causing imbalance. This leads to many health problems and damage, and can even be fatal.
Electrolyte imbalance usually happens because Dehydration Caused by high temperatures, or in some cases severe vomiting or chronic diarrhea. So, it's important to replace lost fluids in these situations.
Also, some diseases can cause it, like kidney diseases andeating disorders and injuries like severe burns can cause electrolyte imbalance.
Mild electrolyte imbalance with no symptoms can be fixed by replacing lost minerals through diet. But more serious imbalance shows some symptoms, which include:-
-
Fatigue.
-
Fast or irregular heartbeat.
-
Numbness or tingling.
-
Muscle weakness and cramps.
-
Headache.
-
Seizures.
So, if you have these symptoms and suspect electrolyte imbalance, talk to a doctor right away.
Loss of electrolytes from the body
The body loses electrolytes, especially sodium and chloride, through sweating. Long workouts or physical activity, especially in hot weather, can cause this loss.
The amount of electrolytes lost in sweat varies from person to person, but estimates show sweat can contain between 40-60 mmol of sodium lost per 1 liter on average.
Since most adults consume way more electrolytes than they lose, they usually don't need to replace them. But some might want to, like those who exercise over two hours or work out in hot weather, by drinking electrolyte-rich sports drinks.
In the end, electrolytes are important for body health and vital functions. The best way to get them is a balanced diet plus staying hydrated, and replenishing losses regularly, especially in hot weather.
