Rationale: Chronic Kidney Disease (CKD) patients often have hypertension, which in turn can worsen the rate of progression of CKD. Salt restriction is important for controlling hypertension and fluid overload. Hence, a low salt diet (LSD) is often advised in the treatment of hypertension in CKD. We assessed the impact of this advise in our patient of chronic kidney diseases.

Methods: CKD patients were advised to avoid high salt food (pickles, papad, chutney commonly used in India with food). Further they were advised to prepare food without salt and to use only one tsp (5 gm) in the whole day. To assess their compliance they are advised to check 24 hour urinary sodium when they follow up in the outpatient clinic. We further compared their salt intake with that of healthy subjects. These healthy subjects were those who were accepted as kidney donors. In healthy subjects also 24 hour urinary sodium was estimated.

Results: There were 211 CKD patients (Mean Age 57.7+15.01) of which 144 were males and 67 females. There 65 healthy subjects (Mean Age 50.63+12.13) of which 23 were males and 42 females. The mean 24 hour urinary sodium in CKD patients was 132.4 mmol (Salt 7.7 gm) and in healthy subjects it was 168.93 mmol (Salt 9.9 gm)

Conclusion: The study showed that salt intake in healthy Indian subjects is much higher (~ 10 g) than that recommended by WHO. The advise to CKD patients to restrict salt does achieve reduction in salt intake but not to the extent desired. To our knowledge, this is the first Indian study comparing salt intake in healthy and CKD subjects.
