Book excerpt: This step-by-step guide to nutritional therapy and colon cleansing includes important self-help strategies for people who want to take responsibility for their own health and well-being. Author Kristina Amelong is a colon hydrotherapist and nutritional counselor who describes her own five-year battle with Irritable Bowel Syndrome and the tools she used to recover. The program that Kristina has designed includes the nutritional research work of Dr. Weston A. Price who studied the diets of fourteen traditional societies during the 1930s and 1940s. His goal was to understand what made human beings healthy and what allowed them to have perfect teeth. The food Kristina recommends to readers are the traditional foods that gave health to the populations that Price researched. When people remove accumulated waste material in their bowel, the body can regenerate with the nutrients available in the Weston A. Price diet. Detoxification and simple, nourishing foods cause people to thrive much like the disease-free native cultures that Price studied.
