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;
