The fundamental principle of nutritional and environmental medicine is to provide the body with the building blocks it needs to carry out growth, repair and detoxification of metabolic wastes. Secondly to minimize or eliminates anything hindering this process. In practice this often means making changes to diet, exercise, lifestyle, the use of supplements etc. This all occurs in line with well established protocols, including a low-reactive diet regime, supplemental nutrient support, heavy metal elimination etc. This approach to medicine can be used in combination with conventional medicine, or in isolation.
