So what is detoxification, anyway? It’s any process that removes a substance that is injurious to your body or that changes a toxic substance so it’s no longer injurious. Dozens of different detoxification methods exist, and I cover the most useful and important ones — including diet, which is the most critical of all — throughout this book. Broadly speaking, though, you can split detoxification up into two categories: internal and external.
Our bodies have an extraordinarily complex array of systems that change, break down, attack and destroy, or eliminate threats to our internal environment and health. For thousands of years these systems have helped humans to enjoy relatively good basic health, but for most of those years the exposure to toxins was very low and rarely caused a problem. That’s not so today. The primary internal systems for detoxification are the stomach, intestines, liver, immune system, kidneys, and lungs. Each one works in a different way to keep us as clean as possible, and you can enhance the detox power of each system.
When it comes to external detoxification, your skin is second to none. Your skin serves as an important barrier that keeps many toxins from entering your body. Your sweat glands, which are extremely important sites for detoxification, are also housed in your skin.
