Sugary Soda and OJ Raise Gout Risk
Researchers tracked gout development and consumption of fructose-rich beverages among 78,906 women in the Nurses’ Health Study. During 22 years of follow-up, 778 women developed gout, and increasing intake of sugar-sweetened drinks was linked to increased gout risk.
Women who had one serving of sugar-sweetened soft drinks a day were 74% more likely to develop gout than women who drank less than one serving per month. Women who had two or more servings per day were at a 2.4-fold increased risk for developing gout, compared to women who drank less than one sugary soda a month.
Drinking orange juice also increased gout risk in women. Participants who had one serving of orange juice a day were 41% more likely to develop gout, and people who had two or more servings per day were at a 2.4-fold increased risk, compared with women who drank less than 6 ounces of orange juice per month.
Diet soft drinks did not increase gout risk among women in the new study.
Fructose May Also Trigger Gout Recurrence
Although the study looked at risk for developing gout, Choi says that women with gout should also cut back on sugary soda and juice to lower their risk of a gout attack. "People who already have gout have a more exaggerated response to fructose, so these findings are even more applicable in gout patients," he says.
"The evidence is strong that these types of drinks are strongly associated with a somewhat increased risk of gout," says Eric Matteson, MD, chair of the department of rheumatology at the Mayo Clinic in Rochester, Minn. "We know too that the risk of obesity, which is also associated with gout, is increased by consumption of soft drinks or 'empty calories,'" he says in an email. "I will tell my patients to limit their consumption of caloric, sugar-containing drinks for their general health and quite possibly reduce their risk of gout."
Industry Takes Issue With Study Conclusions
"This study fails to be meaningful when it comes to informing Americans about the real cause of gout," says Richard Adamson, PhD, a scientific consultant to the American Beverage Association, a trade group based in Washington, D.C.
"The compendium of research conducted on gout shows foods and beverages high in purines such as alcohol, beer, and certain meats are strongly linked to uric acid metabolism and therefore gout," he says in a written statement.
Soft drinks and orange juice do not contain purines.
Moreover, the fructose content of fruit juice and fruit is identical, yet the authors say that eating fruit does not increase gout risk, he says. "This clearly suggests that is not the fructose content that is leading to the increased risk for gout,” Adamson says.
