While the human body is designed to rid itself of harmful substances, the battle is often a losing one. The simple act of digesting food every day, for example, takes a tremendous amount of energy, which the body could otherwise use to repair itself. Fasting is a time-honored way to give your innards a healthy rest . Its also been shown to have therapeutic effects on a number of chronic illnesses like arthritis.
Some purists choose to fast by drinking only water.
If you choose this method, its important to drink the cleanest kind available. Distilled is a good choice. To vary the monotony, try drinking it with a slice of fresh lemon. If this seems too extreme, another option is to drink only fresh juices. While health food stores stock bottled juices, its much better to make your own from fresh fruits and veggies.
