There is a halacha about not sipping your wine, since it is seen as haughty. Perhaps this implies one should not be a connoisseur, at least not ostentatiously.
According to the definition above, anyone who appreciates the differences in taste (or “smoothness” or whatever) between different kinds of scotch is by definition a foodie. Same with wine, micro-brews, etc. I’m not saying it’s wrong–though it may be less healthy than being a connoisseur regarding actual food–just pointing out that “foodism” is more common than people might think (even if people don’t use that label.)
Watching and caring about sports is another thing that’s analogous — a “hobby” or source of pleasure that’s common and hard to justify, though it may not be inherently wrong.
