For years.....I've been waiting on this to occur.
The British Daily Mail (one of my favorite newspapers) wrote up this piece on a new disorder affecting people.....Orthorexia Nervosa. It's basically a healthy food disorder.
Yeah......it's when a person has zapped themselves mentally enough....that they crave only fruit and vegetables....no bread....no dairy products....no meats. So when they get to some stage....they feel all negative and frustrated when they slip up need a piece of bread....negativity goes up in a massive sense.
Has Orthorexia Nervosa made it into the DSM-5.....the handbook/manual that mental health folks use to identify disorders? The simple answer is no. This would require a fair amount of surveys, polls and analysis....which is probably several years away from establishing absolute facts. So, it's a discussed item around mental health experts who have started to see folks who complain about this nervous condition or frustrations surrounding their diet agenda.
Here in Germany, I'd take a guess that one in a hundred folks are already slipping into this disorder. If you survey the dozen-odd state-run networks....there's probably twenty hours a week of nutritional news or shows. Some simply key in on how to eat healthy.....cutting out some grease or fat. But you could see after a while some efforts to maximize on eating healthy. It'd only take a year or two for someone to repeat their daily habits over and over....reaching the point where it's a food disorder.
The curious thing....no one has said how you treat the disorder. Teaching people how to eat an unhealthy menu of food? Forcing people to eat two slices of bacon? It's hard to say how you'd find some way of treating such a person.
Bottom line? You might be so successful in life at extending yourself and making yourself believe in good nutrition....that you might harm yourself with frustrations and negativity over such a diet.
