Question

a key concept to cover with new clients is:
the neurologic tracts of the body
the enzymes in the gastrointestinal tract
the power of the body to heal itself
reasons why the medical industry is making billions of dollars off of pharmaceuticals

Explanation:

When working with new clients, especially in a medical or health - related context, emphasizing the body's inherent ability to heal itself (the power of the body to heal itself) is a fundamental concept. It can be a basis for various treatment plans and patient education. The neurologic tracts and gastrointestinal enzymes are more specialized and technical details that may not be a key starting - point for new clients. Discussing the medical industry's pharmaceutical profits is not a key concept for client education in terms of their own health and well - being.

Answer:

The power of the body to heal itself
