"People with 'bad' food taste..." you do realize is entirely subjective? 'Bad' according to who? No food is 'bad'. Certainly health impact can vary depending on what you eat, but I would say different strokes applies very much to food.
Further, people's tastes do change over time. Some of the stuff I enjoyed as a kid, I can barely touch now, and other things I swore off, I eat regularly now.
