Objective: We aimed to investigate the association of fruit and vegetable consumption with nonalcoholic fatty liver disease (NAFLD) in Chinese patients with type 2 diabetes mellitus (T2DM).

Methods: This cross-sectional study included 2667 Chinese patients with T2DM aged 18 to 76 years. Dietary intake was assessed by food frequency questionnaire, and prevalent NAFLD was diagnosed with abdominal ultrasonography. The primary outcome measurement was multivariate-adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for the prevalence of NAFLD in relation to the highest fruit and (or) vegetable intake compared with the lowest. Secondary analyses were conducted to assess the effects of either fruit or vegetable intake on the fatty liver index (FLI) using multivariable linear regressions.

Results: There were 1445 (54.06%) participants had prevalent NAFLD in this study. Patients with high fruit-vegetable intake (≥500 g/day) had a lower prevalence of NAFLD (52.04% vs. 56.48%), but this difference was not statistically significant (p = 0.065). Vegetable intake had a significantly inverse association with NAFLD (OR: 0.68, 95% CI: 0.52-0.90), but this association was not pronounced with fruit intake (OR: 1.23, 95% CI: 0.89-1.69) or fruit-vegetable intake (OR: 0.90, 95% CI: 0.73-1.10). Additional analyses showed that an increase in vegetable intake was linearly associated with a significant reduction in FLI (β: −1.028, 95% CI: −1.836, −0.219).

Conclusions: Higher vegetable consumption was associated with lower odds of NAFLD in Chinese patients with T2DM, which suggested that increased vegetable intake might protect patients with diabetes against NAFLD.
