" In evolutionary terms, these explanations of course have it back to front. We do not like sugar because it tastes good and abhor vomit because it is foul smelling. Rather, one is delicious and the other repulsive because we were designed to seek the former and avoid the latter. We evolved in environments in which sugar was rare enough that taking all you could was a good strategy, and vomit was certainly full of toxins and pathogens. Individuals who showed these preferences, a bit more than others, would extract more calories and fewer dangerous substances from their environments. On average, these individuals would have an ever so slightly better chance of having offspring than those others. "
