In a BBC story about a woman left with brain damage from a detox diet not based on any medical mechanism balances the two sides of the story:

Side one:
* the nutritionist (training unregulated) who recommended the detox and said that vomiting was a normal part of the process.
* the reflexologist (training unregulated) who mentions that you can tell that it’s working when you feel like crap.

Side two, the “critics” in the story:
* the head dietician at a hospital (training regulated) who mentions that she often has to deal with the medical consequences of people following the advice of nutritionists.
* a doctor (training regulated) at the national Food Standards Agency who points out the actually testable point that your liver is what detoxifies you.

Wow! Two people on each side! I guess that means the issue is not yet settled! How could we possibly find out how the human body eliminates toxic substances?
