Holistic health counseling
I met Holly Hilton a few years ago, and here's a quick link to her Wings of Life website on "holistic health counseling". I like everything she writes on her website about health, stress, diet, and nutrition.
Speaking for myself, I know I've had a number of problems with my health that were stress-related, and my stomach in particular has really changed over the years. In my twenties and early thirties I used to be able to eat anything I wanted (and often did), but over the last five years or so I've learned that I have to be really careful about what I eat if I want to stay healthy.
Although the DofNA website is currently being remodeled, I think their philosophy is also interesting. This phrase in particular really caught my eye: "Where thought goes, energy follows." I've heard a very similar phrase in Tai Chi training, and similar thoughts from people who specialize in yoga or meditation.
