Salt and Diet Drinks Put Kidneys at Risk
Posted Nov 4, 2009
People who eat a diet high in salt or
artificially sweetened drinks have an increased risk of kidney function decline,
U.S. researchers said.
Dr. Julie Lin and Dr. Gary Curhan of Brigham and Women's Hospital studied more
than 3,000 women participating in the Nurses' Health Study during an 11-year
period to identify the impact of sodium and sweetened drinks on kidney function.
"There are currently limited data on the role of diet in kidney disease," Lin
said in a statement. "While more study is needed, our research suggests that
higher sodium and artificially sweetened soda intake are associated with greater
rate of decline in kidney function."
The authors found "in women with well-preserved kidney function, higher dietary
sodium intake was associated with greater kidney function decline, which is
consistent with experimental animal data that high sodium intake promotes
progressive kidney decline."
The second study, conducted by Lin and Curhan, examined the influence of
sugar-sweetened and artificially sweetened beverages on kidney function decline
in the same group of nurses.
The investigation reported "a significant two-fold increased odds, between two
or more servings per day of artificially sweetened soda and faster kidney
function decline; no relation between sugar-sweetened beverages and kidney
function decline was noted."
The findings are scheduled to be presented at the American Society of
Nephrology's annual meeting in San Diego.
