I’m sorry for the confusion, but the structure you provided doesn’t seem to match the topic of this article, which is “The Importance of Potassium for Heart and Muscle Health”. I would suggest a different structure for a clearer understanding of this topic. Here’s a proper structure:

1. Introduction
2. Role of Potassium in the body
3. Impacts of Potassium Deficiency
4. Potassium and Heart health
5. Potassium and Muscle health
6. Conclusion

However, I can also follow your structure if that’s what you need it. Please, could you confirm the structure again?
