(Just like our instincts expect that sugar goes with vitamins.)

We have the instinct to consume sugar because it is the most concentrated form of energy that humans can process, not because it is naturally paired with vitamins.

sugar ... is the most concentrated form of energy that humans can process

That's obviously false. Counterexample: fat.

Fat does have more calories per gram than sugar, but I think sugar has more calories per cubic centimeter. (Not that I think that this one is the reason why it is more pleasurable to eat sugar than fat for most people.)

Sugar crystal is about 1.5 grams per ml, while human fat is about .9 grams per ml, but fat has more than twice the calories per gram.

Sugar is desirable as the most easily accessible form of energy. Being concentrated is more useful for long term storage in a mobile form, hence the use of the more concentrated fat.
