That's true. I remember when I stayed in Japan for a while, initially I found the food underwhelming. It turns out that good 'ol Japanese homecooking isn't designed for the American palate, which is accustomed to lots of sugar, fat, and calories. After a month, though, I loved the food and tasted all sorts of subtle flavors in the vegetables.

Once I came back to America, I found that food here was overwhelming my tastebuds. In particular, I remember trying to drink some Pepsi. It tasted like I was drinking pure sugar (well, I guess that's what it really is). I couldn't even finish it or any other kind of soda. Now I'm able to drink stuff like that again, but that's probably not an improvement. :)
