Abstract

Background There is no epidemiological study on the association between dietary nitrate (NO 3) and nitrite (NO 2) and intakes and the risk of type 2 diabetes (T2D). Objective The aim of this study was therefore to examine the potential effect of dietary NO 3 and NO 2 on the occurrence of T2D. Design This longitudinal study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS) on 2139 T2D-free adults, aged 20-70 years, followed for a median of 5.8 y. Dietary intakes of NO 3 and NO 2 were estimated using a 168-food items validate semi-quantitative food frequency questionnaire, at baseline. Multivariate Hazard Ratios (HR) and 95% confidence intervals (CI), adjusted for diabetes risk score (DRS), and dietary intakes of fat, fiber and vitamin C, were calculated for residual energy-adjusted NO 3 and NO 2 intakes. Since significant interaction (P = 0.024) was found between NO 2 and vitamin C intakes in the multivariable model, stratified analyses were done for < and ≥ median vitamin C intakes. Results Median (inter quartile range; IQR) daily intake of NO 3 and NO 2 were 410 mg/d (343-499) and 8.77 mg/d (7.53-10.2). An increased risk of T2D was observed among participants who had higher intake of total and animal-based NO 2 in participants who had low vitamin C intake (HR = 2.43, 95% CI = 1.45-4.05, HR = 1.88, 95% CI = 1.12-3.15, respectively). We found no significant association between NO 3 in overall, and plant- and animal sources as well, with the risk of T2D. Plant-derived NO 2 was also unrelated to incidence of T2D. Conclusion Our findings indicated that higher intakes of total and animal-based NO 2 may be an independent dietary risk factor for development of T2D in subjects with lower vitamin C intakes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
