The Link: Soda and Kidney Disease

You might avoid soda because of the excess sugar and empty calories it contains. Both regular and diet soda can also increase your risk for chronic kidney disease. Excess soda contributes to weight gain and increases your risk of Type-2 diabetes, which also raises your odds for kidney disease. Limit these beverages to avoid the adverse affects on your nutrition and your kidneys.

Effect of Sugar in Soda

Soda beverages are typically sweetened with sugar in the form of high-fructose corn syrup.(2) A study published in 2010 in the journal “Kidney International” reported that the high amounts of HFCS in soda can elevate uric acid levels. Your kidneys must work harder to clear this acid from your blood. The study found that compared to individuals who consumed less, drinking more than one soda per day significantly increased the risk of chronic kidney disease.


Diet Soda Risks

Artificially sweetened soda is also linked to kidney damage. Research published in 2010 in “Clinical Journal of the American Society of Nephrology” found that women who consumed two or more servings of diet soda per day showed at least a 30 percent decline in overall kidney function. The study concluded that consuming two or more servings of artificially sweetened soda may increase the risk of kidney function decline in women by two-fold. Other research shows that artificial sweeteners may be linked to some neurological disorders.

Other Causes

Kidney disease is commonly caused by diabetes or high blood pressure.Drinking soda can contribute to excess weight, which is a risk factor for developing Type-2 — adult-onset — diabetes, and indirectly, kidney disease. The American Kidney Fund notes that you can inherit a type of kidney disease called polycystic kidney disease. Drinking soda may increase the risk of related diseases such as diabetes; consult your doctor or nutritionist about the the best diet plan for you.
