Bottled juice consumption may increase the risk for type 2 diabetes in adults, but substituting bottled juice with water or fresh juice may decrease the risk, study data show.

Miguel A. Martínez-Gonzalez, MD, PhD, of the department of preventive medicine and public health at the Medical School of the University of Navarra in Spain, and colleagues evaluated data from the University of Navarra Follow-up prospective cohort study on 17,518 adults to determine the relationships between fresh juice consumption, water consumption, bottled juice consumption and type 2 diabetes.

A validated food-frequency questionnaire was used to assess beverage consumption at baseline. Follow-up was a median 10.2 years.

Through follow-up, there were 142 incident cases of type 2 diabetes. The incidence of type 2 diabetes was lower with substitution of water for bottled juice (HR = 0.75; 95% CI, 0.57-0.99). The risk was also lower if the substitution was made with fresh juice (HR = 0.65; 95% CI, 0.43-0.98) and fresh orange juice (HR = 0.56; 95% CI, 0.34-0.92).

The risk for diabetes was increased by 33% with each additional serving per day of bottled juice (HR = 1.33; 95% CI, 1.01-1.75).

“Our study shows that the substation of one serving per day of water or fresh juice (specifically fresh orange juice) for bottle juice was inversely associated with [type 2 diabetes] incidence, and that each additional serving per day of bottled juice was directly associated with a higher risk of diabetes,” the researchers wrote. “A possible health benefit of reducing bottled juice consumption at the expense of water or fresh fruit juice would be recommendable. This type of replacement could be an affordable measure to tackle the diabetes epidemic. However, further longitudinal studies are necessary to confirm these associations.” – by Amber Cox
