Studies in humans have shown that large salt intake increases protein leak in urine which is an important risk factor for developing kidney disease and cardiovascular disease. Reducing salt intake from 10 to 5g / day in a double-blind study has shown to decrease urine protein excretion by 19.4%. Similarly, high salt intake increases your risk of kidney stone formation. The minimum salt intake in a healthy adult is 3.8 grams of salt, to replace the amount lost daily through sweat and urine. The maximum salt an adult should consume is no more than 6 gm per day which is equal to 1.25 tablespoon of salt.


It is expected that an average Indian diet can contain about 8 to 11 grams of salt per day. By restricting the daily salt intake to 6 grams per day will guard your kidneys and at the same time provide the required salts your body needs to keep you well.
