Takadi, I think it's a personal change (regardless of country) more than a generational one. I'm Japanese but living in the US and it took a while to like black coffee. Just a year ago, the UCC canned coffee (which, looking back, doesn't taste like coffee ) was the only think I could drink too! The great thing about living in a country like the US is that you can always find food that isn't "milder, sweeter, saltier, fattier" without much trouble. I'm sure your tastebuds aren't stunted if you try to taste other foods Out of curiosity, grass jelly, durian, bitter melon... , what do all of these taste like?
