A friend recently told me that someone asked her how it’s possible for a person to become able to eat only a handful of foods. And I can totally see where that question’s coming from. Because now that I can eat anything again, even I find it hard to believe that there was a point when I could only eat 8 foods. But having learned about the brain’s ability to adapt and change itself – both for the better or for the worse – how I suddenly became able to eat only 8 foods actually makes “perfect sense”. Here’s how it happened.
