Nutritional Therapist Elizabeth Hartland explains: “Many people will have heard about the benefits of healthy bacteria and the pro-biotic drinks you can now buy, but symptoms of an unhealthy digestive system, such as constipation, are less talked about. Charles de Coti-Marsh believed that a constipated state creates toxins which stay in the bowel, enter the blood stream and poison the body, the long term effects of which can be diseases such as arthritis. Drinking plenty of water can help avoid constipation.”
