Consumption of fruit fiber reduces the risk of type 2 diabetes, but this effect is only statistically significant in high-quality studies (Newcastle-Ottawa Scale score ≥ 7).
Ensure your fruit fiber intake comes from whole, high-quality dietary sources. The protective effect of fruit fiber on diabetes risk is evident in rigorous studies. Focus on getting fiber from whole fruits rather than supplements, and maintain a diet rich in these foods.

However, subgroup analysis results showed that a significant reduction in the risk of type 2 diabetes incidence for consumption of fruit fiber in these high-quality studies in which scores were 7 or greater
Why this rating
Subgroup analysis of a meta-analysis; the overall effect was null (RR 1.00), requiring high-quality studies to see the benefit.
