Nutritional supplementation for stable chronic obstructive pulmonary disease (COPD) shows mixed results. While some dietary changes may help, long-term benefits on weight and exercise capacity are inconsistent, with further research needed.

Area of Science:

  • Respiratory Medicine
  • Clinical Nutrition
  • Evidence-Based Medicine

Background:

  • Chronic obstructive pulmonary disease (COPD) management often involves addressing nutritional status.
  • Nutritional supplementation is explored as an adjunct therapy for patients with stable COPD.

Purpose of the Study:

  • To systematically review randomized controlled trials (RCTs) on nutritional supplementation in stable COPD.
  • To clarify the impact of different nutritional strategies on relevant patient outcomes.

Main Methods:

  • Systematic overview of RCTs sourced from multiple databases and expert consultation.
  • Independent selection, quality assessment, and data extraction by two reviewers.

Main Results:

  • High carbohydrate intake negatively impacted exercise capacity and ventilatory function.
  • Longer-term supplementation (>2 weeks) showed variable effects on weight and anthropometry.
  • Anabolic steroids increased body mass but had minimal effect on exercise capacity; growth hormone was ineffective.

    • Conclusions:

    • Patients with COPD and marginal ventilatory reserve may benefit from high-fat diets.
    • Consistent benefits of nutritional repletion on body weight were not demonstrated in trials exceeding two weeks.
    • Further research is required to optimize nutritional support, exercise, and anabolic agents for COPD patients.
