Along with chloride sodium helps to maintain the balance of fluids in your body.
Sodium also helps to transmit nerve impulses and influences muscle contractions and relaxation.
Your kidneys naturally balance the amount of sodium which is stored within your body to optimise your health.
If you have too much sodium in your body your kidneys will excrete the excess in your urine and if you have too little or are low your kidneys will hold onto the sodium.
Most people consume well enough sodium in their diet so no worry about sodium deficiency.
Sodium is in many foods that have salt content including prepared foods, cold cuts of bacon, soups, condiments and fast food and most people tend to salt their food at the table also.
