This study examined the association between fruit, vegetable, and fruit juice intake and development of type 2 diabetes mellitus (DM). 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 food frequency questionnaire every 4 years. 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, while the same increase in whole fruit consumption was associated with a lower hazard of DM. An increase of 1 serving/day in green leafy vegetable consumption was associated with a modestly lower hazard of DM, whereas the same change in fruit juice intake was associated with an increased hazard of DM.
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.
"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," the study authors write. "These associations were independent of known risk factors for type 2 DM, including BMI [body mass index], physical activity, age, postmenopausal hormone use, family history, smoking, alcohol intake, total energy intake and consumption of whole grains, nuts, processed meats, coffee and potatoes."
