The Keystone Approach is based on a profound shift in our understanding of the causes of autoimmune arthritis and psoriasis, elucidated by the latest medical research. Specifically, a series of groundbreaking new clinical studies have found that these conditions are often driven by the immune system overreacting to certain gut bacteria. This overreaction is caused by a more permeable gut barrier, the overgrowth of pathogenic gut bacteria or yeasts, and the lack of beneficial immune-calming microbes.

This innovative new book provides a systematic, evidence-based plan to address each of these elements, from the perspective of an acclaimed science writer who successfully treated her own debilitating psoriatic arthritis. This easy-to-follow plan, based on an in-depth analysis of more than 400 scientific studies, will likely help a wide variety of autoimmune conditions, but it is most specifically tailored to address the underlying causes of diseases in the spondyloarthropathy family, which includes psoriasis, psoriatic arthritis, juvenile arthritis, ankylosing spondylitis, uveitis, Crohn's and ulcerative colitis.

"It's rare to find an alternative health book so thoroughly backed by scientific studies, but The Keystone Approach is not only a specific, authoritative recommendation, but represents a satisfying intersection of traditional and alternative approaches to healing. It should be in any health collection where autoimmune diseases are of interest." - Midwest Book Reviews
