DM: Protein Amount (2014)

DM: Protein Amount (2014)

• Intervention
  In adults with type 1 and type 2 diabetes, what is the relationship of differing amounts of protein, independent of weight loss, on diabetic kidney disease (GFR and/or proteinuria)?

  • Conclusion
    Research reports that the amount of protein (ranging from 0.7g to 2.0g per kg per day) had no effect on glomerular filtration rate (GFR), independent of weight loss, in adults with type 1 and type 2 diabetes and diabetic kidney disease (DKD). No studies reported on proteinuria.
  • Grade: I
    • 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.

  In adults with type 1 and type 2 diabetes, what is the relationship of differing amounts of protein, independent of weight loss, on glycemia (A1C or glucose)?

  • Conclusion
    Research reports mixed results regarding the effects of the amount of protein (ranging from 0.8g to 2.0g per kg per day) on fasting glucose levels and A1C, independent of weight loss, in adults with type 1 and type 2 diabetes and diabetic kidney disease (DKD).

  In adults with type 1 and type 2 diabetes, what is the relationship of differing amounts of protein, independent of weight loss, on insulin levels (exogenous/endogenous)?

  • Conclusion

    There were no studies identified regarding the relationship of differing amounts of protein, independent of weight loss, on insulin levels (exogenous or endogenous) in adults with type 1 and type 2 diabetes.

    Intervention studies are needed regarding the impact of differing amounts of protein on insulin levels in adults with diabetes.
