I’ve heard about orthorexia by listening to one of my favorite podcasts: http://www.fat2fitradio.com/
From Wikipedia:
Orthorexia: an eating disorder characterized by excessive focus on eating healthy foods. In rare cases, this focus may turn into a fixation so extreme that it can lead to severe malnutrition or even death.
So, if you’re eating unhealthy and stuffing your face with all the crap you can find you turn obese. You will probably die of one of the many diseases obesity causes (of at least it favors). If you pay attention to what you eat (and you have to do this in a controlled almost obsessive way to be successful in the long term) you might end up with this newly invented discovered disease. In severe cases you die. So the extremes are not very encouraging in either cases.
So I guess that, as with everything in life, the key is moderation. Too much of something can harm you :) Of course, we all die eventually so you should take this piece of information with a grain of salt. But not too much salt, as it’s bad for you :)
You can find a quiz to help you figure out if you have this new trendy disease here: http://skwigg.com/id8.html.
Found out about the quiz in the same episodeof the podcast mentioned above.
