COPD: Macronutrient Composition (2019)

• Intervention
  Does the macronutrient composition (percentage distribution) of the diet have an effect on outcomes in adults with COPD?

  • Conclusion

    Limited evidence showed improvement in lung function (forced vital capacity, tidal volume), but not forced expiratory value in 1 second or vital capacity when adult men with COPD consumed a higher fat (50%), lower carbohydrate (28%) diet. 

  • 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.
