High fructose intake in the form of added sugar is independently associated with higher blood pressure (BP), according to the results of a cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES 2003 to 2006), reported online ahead of print July 1 in the Journal of the American Society of Nephrology.

“The recent increase in fructose consumption in industrialized nations mirrors the rise in the prevalence of hypertension, but epidemiologic studies have inconsistently linked these observations,” write Diana I. Jalal, from University of Colorado Denver Health Sciences Center in Aurora, and colleagues. “We investigated whether increased fructose intake from added sugars associates with an increased risk for higher BP levels in US adults without a history of hypertension.”

In the study sample of 4528 adults without a history of hypertension, median fructose intake was 74 g/day, which is approximately equivalent to 2.5 sugary soft drinks each day. Increased fructose intake of at least 74 g/day was independently and significantly associated with higher odds of elevated BP levels.

“These results suggest that high fructose intake, in the form of added sugar, independently associates with higher BP levels among US adults without a history of hypertension,” the study authors write.

“These findings support the hypothesis that increased intake of fructose may result in hypertension through a variety of mechanisms,” the study authors conclude. “Limiting fructose intake is readily feasible, and, in light of our results, prospective studies are needed to assess whether decreased intake of fructose from added sugars will reduce the incidence of hypertension and the burden of cardiovascular disease in the US adult population.”
