Abstract

OBJECTIVES
Mushrooms, known for their nutritious and functional components, are considered healthy and medicinal. This study investigated the prospective association between dietary mushroom consumption and the incidence of type 2 diabetes among Korean adults aged ≥40 years.

METHODS

In total, 16,666 participants who were not taking anti-diabetic medication or insulin and had normal fasting blood glucose (FBG; <126 mg/dL) were included. We used the cumulative average dietary consumption of mushrooms as an exposure metric, calculated from food frequency questionnaires at every follow-up, along with covariates collected during a baseline survey. To estimate incidence rate ratios (IRRs) for type 2 diabetes, a modified Poisson regression model with a robust error estimator was applied.

RESULTS

In multivariable models, dietary mushroom consumption was inversely associated with type 2 diabetes incidence in both genders (men: IRR, 0.65; 95% confidence interval [CI], 0.47 to 0.90; p<sub>linearity</sub>=0.043 in the highest quartile (Q4) vs. the lowest quartile (Q1); women: IRR, 0.70; 95% CI, 0.54 to 0.93; p<sub>linearity</sub>=0.114 in Q4 vs. Q1). The inverse association remained after adjustment for dietary factors instead of dietary quality index, the baseline FBG, and the exclusion of incidence within the first year. Additionally, no significant interaction was found regarding the risk of type 2 diabetes between dietary mushroom consumption and participants’ gender or other factors.

CONCLUSIONS

Dietary mushroom consumption was inversely linked with the risk of type 2 diabetes incidence in both genders, indicating the beneficial role of mushrooms in preventing the disease.

Summary

Korean summary
- 흔히 사용하는 버섯의 식이 섭취량이 증가함에 따라 한국 40세 이상 성인에서 제2형 당뇨병 발생 위험이 낮았다. - 이러한 역관계는 성별과 다양한 식이 배경에서도 일관성을 유지하였고, 이는 버섯이 제2형 당뇨병 예방에 있어 잠재적인 식이요소로서의 가능성을 보여주는성을 보여주는 보여주는 결과이다.

Key Message
• Increased dietary consumption of commonly used mushrooms is associated with a lower risk of type 2 diabetes incidence among adults aged 40 years or older in Korea. • This inverse relationship remains consistent across genders and various dietary backgrounds, underscoring the potential of mushrooms as a preventive dietary component against.
