BACKGROUND AND AIMS
The relationship between juice consumption and type 2 diabetes (T2D) has not been widely evidenced. Our aims were to prospectively evaluate the associations with T2D incidence of: 1) isovolumetric substitution of a water serving/day for one of fruit juice (different types), and of fresh fruit juice for its bottled version; 2) consumption of total, fresh or bottled juice; 3) energy intake from juices.

METHODS AND RESULTS
We followed 17,518 adults without T2D at baseline. Beverage consumption was assessed at baseline through a validated food-frequency questionnaire. The outcome was T2D incidence, according to American Diabetes Association's criteria. During a median follow-up of 10.2 years, 142 incident cases of T2D were identified. In substitution models, the substitution of water for bottled juice was associated with a lower T2D incidence, and also if the replacement was done by fresh juice, or especially fresh orange juice [HR 0.75 (95% CI 0.57-0.99), 0.65 (95% CI 0.43-0.98) and 0.56 (95% CI 0.34-0.92); respectively]. Each additional serving/day of bottled juice was directly associated with T2D incidence [HR 1.33 (95% CI 1.01-1.75)]. No significant association was observed for energy coming for bottled juice [HR 1.74 (95% CI 0.94-3.20)].

CONCLUSION
Our results suggest that isovolumetric substitution of water or fresh juice for bottled juice was inversely associated with T2D incidence in a long-term prospective study. Thus, these substitutions could be useful to tackle the diabetes epidemic.
