Background: The safety of high egg intake in view of its impact on glucose metabolism remains inconclusive. The aim of the study was to assess the relationship between egg intake, dietary patterns and elevated fasting glucose (FG) level in a selected group of Polish adults.Methods: The study group consisted of 1630 adults who participated in the Polish arm of the Prospective Urban Rural Epidemiological Study. Dietary intake, including egg intake, was assessed based on the data from the Additional file 2 Food Frequency Questionnaire previously validated for the population of Lower Silesia. DPs were derived using principal component analysis. FG levels ≥100 mg/dl were considered elevated. Subjects who used antidiabetic drugs were included in the group with elevated FG levels.Results: Egg consumption increased in higher quartiles of "Western" and "traditional" DPs in both men and women (p < 0.0001). In a crude model each 10 g of eggs consumed per day was associated with 7% increased risk (OR 1.07; 95% CI: 1.01-1.15) of elevated glucose level in the overall group and 10% increased risk (OR 1.10; 95% CI: 1.01-1.21) of elevated glucose level in the group of men. Men who consumed at least five eggs per week had higher risk for elevated FG level compared to men who consumed at most one egg per week (OR 1.79; 95% CI 1.13-2.84), but this relationship became insignificant when the data were adjusted for DPs. In the group of women no association between egg intake and elevated FG level was observed.Conclusions: Higher egg intake may be associated with the overall unhealthy dietary habits, which is why the number of eggs consumed daily should not be considered an independent risk factor for elevated fasting glucose level.
