This is a curious article. I have a mix of emotions ranging from all the above posts, which are all valid in my opinion.
Firstly, this is Fox (mainstream, yet controversial) and of course there is a financial interest involved (his book/site). Secondly, the word "cure"--obviously salacious and definitely not warranted for the undisclosed amount of time off drugs, but definitely no more than 5 years. Thirdly, to say food/exercise/stress mgmt have no merit is absurd for anyone in any state of health or lack thereof. Fourthly, supplements wildly range in potency, effectiveness, impurities, purported benefits... Fifthly, everyone here can say there is not a satisfactory drug on the market to handle Crohn's effectively as the side effects are just as real as the benefits and the price tags.
Anyone can include most of the elements of "alternative therapy" with complementary pharmaceuticals or without, to your own degree of fanaticism or diligent adherence or not. Overall, the article equally does great disservice to the alternatives mentioned while at least putting the idea out there as a brief interruption to the continual push of Humira commercials constantly streaming on the television, sometimes commercial break after commercial break (in the states, you know what I'm saying). I think everyone has to decide for themselves, but this article is ridiculous.
