Purpose Few studies have evaluated the association of fruit and vegetable (FV) intake and pre-diabetes. However, these studies are very limited and incomplete. Therefore, the aim of our study was to compare FV consumption and their subgroups between pre-diabetic and control subjects. Methods This case-control study included 300 individuals, 150 subjects with normal fasting blood glucose (FBG), and 150 pre-diabetic subjects who were matched for sex and age. We collected the participants' anthropometric and physical activity data and measured their blood glucose level. A 168 items semi-quantitative food frequency questionnaire (FFQ) was used for estimating the FV intake. Results After adjustment for confounding variables, participants in the lower quartiles of FV and total fruit intake were more likely to experience pre-diabetes compared with those in the higher quartiles (p trend < 0.007). In addition, cruciferous vegetables, other vegetables, and berries were inversely associated with pre-diabetes (p < 0.05), although a distinct dose-response relationship was not found. Unexpectedly, higher intake of dark yellow vegetables was significantly associated with a higher chance of pre-diabetes (p trend = 0.006). Other vegetable and fruit subgroups did not show any significant relationship with this disorder. Conclusion Our findings suggest that higher intake of total FV and total fruits might be associated with lower odds ratio of pre-diabetes.
