"Taking a pharmaceutical probiotic while continuing to drink coffee and eat doughnuts is like throwing a Tic Tac at a charging elephant."
I need to borrow this line from the Clean book---partly because it is just a really good comparison, and also because I laughed out loud when I read it.
In this section of the book, Dr. Junger was specifically talking about addressing intestinal problems by taking probiotics...but I think you could substitute any one action into where it mentions taking probiotics....
The point is that we too often address one of our symptoms of a health issue without getting to the root of the problem. Dr. Junger also talks about plants, and how when a gardner notices his plants doing poorly, he pulls them up to examine the roots. The condition of the leaves (surface) are the symptoms of a problem that is going on at a deeper level.
What are your symptoms? This is very important to identify, but once you do, make sure you look deeper and try to address the problems. This will lead to a really exciting discussion about how the condition of our intestines are indicative of our health!
