The American Dietetic Association has published evidence-based nutrition guidelines for the treatment of heart failure and chronic obstructive pulmonary disease.

Registered dietitians will advise doctors and patients about how to integrate the new practice with a view to improve the quality of care and quality of life of affected patients.

For COPD patients it is now advisable to consume the recommended dietary allowances for antioxidant vitamins A, C, and E as well as the adequate intake for omega-3 fatty acids.

Stable heart failure patients, on the other hand, should be urged to consume the appropriate amount of protein every day, restrict sodium intake to less than 2,000 mg per day, consume folate in the form of food or a combination of B6, B12, and supplementation, and drink 48-64 oz of fluid daily.

ADA experts developed the guidelines based on the examination of existing research, and the results were reviewed by multidisciplinary teams consisting of RDs, physicians, respiratory therapists, pharmacists, registered nurses and faculty from institutions including Harvard Medical School, University of Pittsburgh School of Medicine, University of Texas, University of Tennessee and Oregon Health and Science University.
