Salt and Diet
The sodium element regulates the body's fluid balance which helps maintain normal pressure and keeps our nerves and muscles working properly. While chloride, aids digestion and enhances the flow of carbon dioxide to the lungs.
Each of us needs about 2 grams of sodium per day. This is obtained from natural levels present in fish, fruit, meat and vegetables; however large amounts are also added to processed foods, so our intake can easily increase to as much as five times the amount we actually need.
It is estimated that between 20 and 25% of the British population is susceptible to high blood pressure due too much salt in the diet. Because of this, they may increase the risk of suffering a stroke as well as developing kidney problems or coronary heart disease.
As it's difficult to tell who is at risk, it makes sense to reduce the amount of salt we eat in order to maintain a balanced, healthy diet. See 'Salt'
