By completely cleaning out your system with a colon cleanse you will really be giving your body a clean slate to work with. In this way you will be able to get an accurate assessment of what is impacting your body.
While you are cleaning out your body, why not help it recover from the damage the food intolerance has been doing? In this case you should look at an oxygen based colon cleanse.
An oxygen based colon cleanse uses a natural chemical reaction to clean your digestive tract. The byproduct of this reaction is oxygen. Oxygen is fantastic for your body and gives it a boost of energy. That means not only will you be able to get rid of the backed up food that is causing problems, but you will also give you body a nice healing bump to get back to normal before you try to sort out the problem foods in your diet.
