DM: Fiber (2014)

  • Intervention
    In adults with type 1 and type 2 diabetes, what is the relationship of differing amounts of fiber in the diet (no supplements or fiber-added foods), independent of weight loss, on CVD risk factors (lipids and blood pressure)?
    • Conclusion
      One study regarding the relationship of differing amounts of dietary fiber in the diet, independent of weight loss, on CVD risk factors reported no significant effect on total cholesterol, HDL-cholesterol or LDL-cholesterol levels in adults with type 2 diabetes. However, reported dietary fiber intake (approximately 20g per day) did not differ among the groups. The high carbohydrate/fiber group reported significantly higher soluble fiber intake compared to the weight management group. The study reported that triglyceride levels were lower among subjects consuming less soluble fiber.

      Subjects did not have or were not described as having any disorders of lipid metabolism or hypertension and none of the studies reported on blood pressure or adults with type 1 diabetes. Additional long-term studies are needed to ascertain the relationship of differing amounts of fiber in the diet, independent of weight loss, on lipid profile in adults with diabetes, especially those with disorders of lipid metabolism and hypertension.
    • Grade: III
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    • Evidence Summary: In adults with type 1 and type 2 diabetes, what is the relationship of differing amounts of fiber in the diet (no supplements or fiber-added foods), independent of weight loss, on CVD risk factors (lipids and blood pressure)?
