I'm actually detoxing (or attempting to) right now. My chiro put me on this meal replacement powder called Ultrainflamx. I have it for breakfast blended with almond milk and frozen fruit. Its supposed to help heal the intestinal wall so toxins cannot leak out. The second part of this plan is to avoid eating foods that contribute to the toxicity/allergy. This is the hard part for me as the dietary guidelines say to exclude wheat, oats, corn, tomatoes, peppers, white potatoes, beef, dairy, eggs, coffee, and alcohol (& of course sugar). I am now eating spelt bread and bought some spelt flour for baking. I am also going to try some of the non-wheat varieties of pasta. I am eating cooked vegetable and some salads and good protein (tofu, free range chicken). I am avoided processed foods (even flours). I also take a supplement that is supposed to kill any parasites that are lurking in my intestines. I go back to the chiro today. I've only been doing this since Monday, but already feel a lot better.
Good luck with whatever route you take.
