Macro partitioning
High dietary glycemic load combined with low cereal fiber intake significantly increases the risk of developing type 2 diabetes, whereas high cereal fiber intake is inversely associated with diabetes incidence.
Focus on the quality and fiber content of your carbohydrates rather than just cutting them out. Choose foods with a low glycemic load and high cereal fiber (like whole grains, vegetables, and legumes) to significantly lower your risk of type 2 diabetes. Avoid high glycemic load foods, especially if your fiber intake is low.
In this study the relative risk of type 2 diabetes was 2.50 (95 % CI 1.14, 5.51) for women with the combination of high GL and low-fibre intake (GL > 165 and cereal fibre < 2.5 g/d v. GL < 143 and cereal fibre > 5.8 g/d)
Why this rating
Based on large prospective cohort studies (Nurses' Health, Health Professionals) with consistent inverse associations for fiber, though intervention trials are lacking.
