PDM: Prediabetes (2013)

• Assessment
  In individuals with prediabetes, what is the impact of total fiber intake, independent of weight loss, on glycemic-related outcomes (such as fasting blood glucose, random blood glucose, two-hour post-prandial blood glucose, A1C)?

  • Conclusion

    Limited research reports no significant impact of total fiber intake, independent of weight loss, on fasting blood glucose, two-hour post-prandial blood glucose or A1C in individuals with prediabetes.

    Additional intervention studies are needed to ascertain the effect of total fiber intake on glycemic-related outcomes in individuals with prediabetes.

  • 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.

  In individuals with prediabetes, what is the impact of total fiber intake, independent of weight loss, on lipid outcomes (TG, HDL)?

  • Conclusion

    Limited research reports no significant impact of total fiber intake, independent of weight loss, on triglycerides or HDL cholesterol in individuals with prediabetes.

    Additional intervention studies are needed to ascertain the effect of total fiber intake on lipid outcomes in individuals with prediabetes.

  In individuals with prediabetes, what is the impact of total fiber intake, independent of weight loss, on anthropometric outcomes (WC)?

  • Conclusion

    Limited research reports mixed results regarding the impact of total fiber intake, independent of weight loss, on waist circumference in individuals with prediabetes.

    Additional longer-term intervention studies are needed to ascertain the effect of total fiber intake on anthropometric outcomes in individuals with prediabetes.
