“As dietary modification is a low-cost, simple intervention, it offers the potential to significantly reduce the burden from chronic kidney disease, while also protecting from cardiovascular disease,” Smyth added in the study involving 544,635 participants.
These findings were confirmed by a separate study that found that reducing salt intake reduces albuminuria, or excess protein in the urine, which is a hallmark of kidney dysfunction.
In the study involving 120 rural villages in China, researchers analysed the results of an 18-month sodium reduction programme.
The findings of the study led by Meg Jardine from The George Institute for International Health, in Australia and her colleagues revealed that individuals who underwent sodium reduction had a 33 percent decreased likelihood of having albuminuria compared with individuals in the control villages.
Both the studies were presented at ASN (American Society of Nephrology) Kidney Week Nov 11-16, 2014 in Philadelphia, Pennsylvania.
