Hm, no sweet tooth, eh? That's a huge health advantage I suppose!
Honestly i've noticed over time my fondness for the trash food like Chocolate, Cola, etc, has been dying away. In my 20's I could still devour a couple of pizzas with coke, and have a large chocolate bar daily.
Now I go months without drinking much other than water, and a whole pizza kills me. I certainly don't feel healthier, even though I technically am...
I like sweet stuff, but more in a solid than in a liquid state. You know, physics plus the fact that solid are more ordered than liquids ;) But what is true is that with age, tastes change and go further away from the sweet region of the spectrum. I for instance like super-bitter chocolate. I also eat less.
I however do not know whether this is significant. The US would provide super counter-examples I guess.
