The answer to that question is this; when the body remains under stress for significant amounts of time from your day-to-day lifestyle and contact with toxicity (like from unhealthy food, substances, the environment, chemical based products, etc.), it becomes unable to cleanse itself naturally because the body is overwhelmed and distressed. Unfortunately, the byproduct of a toxic body leads to unwanted health challenges, such as: obesity, premature aging, poor skin and even cancer.
