Preachin' to the choir here, but interesting study, nonetheless: Intake of Fruit, Vegetables, and Fruit Juices and Risk of Diabetes in Women. Bazzano LA, Li TY, Joshipura KJ, Hu FB.

OBJECTIVE: To examine the association between fruit, vegetable, and fruit juice intake and development of type 2 diabetes mellitus (DM). RESEARCH DESIGN AND METHODS: A total of 71,346 female nurses ages 38-63 years, who were free of cardiovascular disease, cancer, and DM in 1984 were followed for 18 years and dietary information was collected using a semi-quantitative food frequency questionnaire every 4 years. Diagnosis of DM was self-reported. RESULTS: During follow-up, 4,529 cases of DM were documented and cumulative incidence of DM was 7.4%. An increase of 3 servings/day in total fruit and vegetable consumption was not associated with development of DM (multivariate-adjusted hazard ratio [HR], 0.99; 95% Confidence Interval [CI], 0.94 to 1.05) while the same increase in whole fruit consumption was associated with a lower hazard of DM (HR, 0.82; 95% CI, 0.72 to 0.94). An increase of 1 serving/day in green leafy vegetable consumption was associated with a modestly lower hazard of DM (HR, 0.91; 95% CI, 0.84 to 0.98), whereas the same change in fruit juice intake was associated with an increased hazard of DM (HR, 1.18; 95% CI, 1.10 to 1.26). CONCLUSIONS: Consumption of green leafy vegetables and fruit was associated with a lower hazard of DM, whereas consumption of fruit juices may be associated with an increased hazard among women. Breakdown courtesy of Dr. John Briffa: An increase in whole fruit consumption of 3 servings per day was associated with an 18 per cent reduced risk of diabetes. An increase in green vegetable consumption of 1 serving a day was associated with a 9 per cent reduced risk of diabetes. An increase in fruit juice consumption of one serving a day was associated with an 18 per cent INCREASED risk of diabetes.
