Humans are humans, we taste generally the same as each other.
I about burst into laughter at one single thought: Cannibalism!
I know that's not what you meant, but still.
It's true that people have some of the general same tastes when it comes to food and drink, but then there are many differences - and these differences arise from something different than just a person's mental stance (the difference in culture and what is acceptable to eat for a person's society). I mean, how do you explain how some people hate certain foods (peas, green beans, asparagus, watermelons, cherries) that other people love? But then, I guess a counter for that would be that taste buds are different for each person, so it might actually be more biological than mental/preferential.
.....And stuff.
