It is known that high salt intake is injurious to health, especially for those with cardiovascular problems but new studies have shown that more sodium affects kidney directly.
New research found that an average intake of 4.7 grams a day is enough to increase the risk of damaging kidney to the extent of needing dialysis, while average is about 2g a day.
"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," said Andrew Smyth from the National University of Ireland, Galway. The study second the findings of another study on Chinese recently.
The second study was conducted on 544,635 participants in 120 Chinese villages over a period of 18 months with high and low salt intakel levels. It has substantiated the previous finding that reducing salt intake reduces albuminuria, or excess protein in the urine leading to kidney dysfunction.
The study on Chinese villagers was led by Meg Jardine from the George Institute for International Health in Australia and her colleagues has shown that those who went for reduced sodium intake had a 33% decrease in the likelihood of having albuminuria compared with those without the reduction in salt intake.
All these findings were made during the presentation of papers at the American Society of Nephrology’s Kidney Week conducted from Nov 11 to 16 in Philadelphia, Pennsylvania.[tags, salt, sodium, intake, harmful, kidney, albuminuria,
