Optimal health refers to an individual's physical, emotional, and mental well-being and their ability to achieve personal health goals. Chronic conditions are long-lasting medical issues that can be managed but not cured, and they are the leading cause of death and disability in the U.S. Maintaining optimal health through good nutrition, physical activity, and lifestyle habits can help prevent chronic conditions and allow those with chronic conditions to experience fewer symptoms and a lower risk of additional health issues. However, adapting new health behaviors requires commitment over the long-term.
