COPD: Macronutrient Composition (2019)
Does the macronutrient composition (percentage distribution) of the diet have an effect on outcomes in adults with COPD?
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 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.
