Our Mission
The mission of the National Health Association is to educate and empower individuals to understand that health results from healthy living. We recognize the integration of all aspects of health: personal, environmental, and social.
We communicate the benefits of a plant-based diet, exercise and rest, a healthy environment, psychological well-being, and when indicated, the use of fasting.
