Sodium intake affects urinary albumin excretion especially in overweight subjects
I have to admit, that I have usually told patients that sodium intake is really not as important as most believe it is (with the exception of processed foods–which are generally higher in sodium). There seems to be only a small percentage of the population that is salt sensitive. The rest don’t experience much effect from salt intake.
However, this article suggest an alternative opinion, that salt intake in overweight patients adversely effects the kidney’s excretion of albumin. Remember that the kidney should not lose any proteins–protein in the urine can be a sign of renal problems. Microalbuminuria has shown to be related to the degree of insulin resistance. So, might the salt in this study be affecting insulin resistance in a negative way somehow?
