As far as food goes, it's actually this topic in reverse. I now hate sweets - candies, chocolates, etc. are disgusting to me. I do enjoy dark chocolates still, and licorice (especially black licorice)
Beer. As a child, when given my first taste of beer, I thought it was gawd awful. Even in my teen years I detested alcohol in it's many forms. Now I love drinking beer at dinner. Sam Adams is my homie.
My dad's brand of music. Now, the likes of Rush and Black Sabbath are like gods to me.
As with Dorkness, women. Love me some women now, though.
EDIT: How could I forget sports? I used to HATE sports, now American football and baseball are my all-time favorite things outside of music.
