Yep, it's exactly the same thing here! If I eat something salty, I want something sweet to balance it out. Add to that the fact that I've always had a sweet tooth, and have always satisfied that urge to have something sweet after something salty. I found that having a measured portion (1/4 cup to 1/2 cup) of sliced strawberries with cool whip satisfied my sweet tooth. I also indulge VERY occasionally in a frankenfood. (Namely, ice cream!)
But it is definitely an interesting subject. I wonder if there IS actually some type of......something.....that makes your body want both....
