Vegetable intake and T2D risk: The role of BMI

What is it about?

This study examined the relationship between vegetable and potato intake and the risk of type 2 diabetes (T2D). It found that higher intake of total vegetables (excluding potatoes) was inversely associated with incident T2D. Participants in the highest versus lowest quintile of vegetable intake had a 21% lower risk of T2D. The association plateaued at a vegetable intake of 150-250 g/day. Higher intake of green leafy and cruciferous vegetables was inversely associated with T2D after accounting for underlying dietary pattern. Total potato intake was not significantly associated with T2D after accounting for underlying dietary pattern. Baseline BMI partially mediated the inverse association of total vegetable and vegetable subgroup intake with incident T2D. The study concluded that a higher vegetable intake might help mitigate T2D risk, partly by reducing BMI.

Why is it important?

This study is important because it provides evidence that a higher intake of vegetables, but not potatoes, may help mitigate the risk of developing type 2 diabetes (T2D). The findings contribute to the understanding of the relationship between dietary factors and the incidence of T2D, which is a leading cause of global morbidity, mortality, and health care system burden. Key Takeaways: 1. A higher intake of total vegetables (excluding potatoes) was inversely associated with incident T2D. 2. Participants in the highest versus lowest quintile of vegetable intake had a 21% lower risk of T2D. 3. Higher intake of green leafy and cruciferous vegetables was inversely associated with T2D. 4. Total potato intake was not significantly associated with T2D after accounting for underlying dietary pattern. 5. Higher vegetable intake was associated with a healthier underlying dietary pattern.
