1. How much salt should I eat to maintain normal sodium levels?
Most sodium comes from table salt. In the UK, we take in an average of 3-4 grams (3000–4000 mg) of sodium per day. However, you need far less than this to meet the needs of the body. According to the Food Standards Agency, total daily sodium intake should not exceed 2500 mg.
2. Is anyone at particular risk for low or high sodium levels?
Yes. People who have diarrhoea, vomiting, profuse sweating, kidney disease, or congestive heart failure may have low sodium levels. The frail elderly and those with diabetes or high blood pressure may have elevated sodium levels.
3. Should athletes pay particular attention to re-hydrating after playing sports to keep their sodium levels up?
Yes. It is very important to drink plenty of fluids—particularly water—during and after any strenuous exercise.
