From the Research
For patients with cardiomyopathy, the recommended sodium intake should not be restricted to less than 3 g/day, as current evidence suggests that moderate sodium intake (3-5 g/day) is associated with the lowest risk of cardiovascular disease and mortality, and restricting sodium intake too much may increase the risk of adverse health outcomes 1, 2, 3. The current evidence does not support the fact that dietary sodium intake restrictions for patients with heart failure have a positive impact on mortality rates, rehospitalization rates, and quality of life 1. Some key points to consider when advising patients with cardiomyopathy about sodium intake include:
- Avoiding processed foods, canned soups, fast food, and deli meats which are high in sodium
- Using herbs, spices, lemon juice, and vinegar for flavoring instead of salt
- Reading nutrition labels carefully to estimate sodium intake
- Cooking at home with fresh ingredients to control sodium intake
- Being aware that sodium restriction may not have a positive impact on clinical outcomes in patients with heart failure, and that more evidence is required to explore the differences in the impact of various levels of dietary sodium restriction on outcomes and symptom management indicators 1, 2, 3. It is essential to consider the individual patient's needs and circumstances when providing guidance on sodium intake, and to prioritize a balanced and moderate approach to sodium consumption, rather than strict restriction 2, 3.
