What is the point to eating delicious food? The function of food is to nourish the body, not taste good.
what's the point of proper grammar or song? the purpose of language is to get a point across, not to be beautiful.
what's the point of nice cars? the purpose of a car is to go from A to B.
what's the purpose of nice looking clothes? the purpose of clothes is to protect from the elements.
what's the purpose of etc. etc.
stop being a fag and enjoy life, anon. nice things are nice.
Somewhere around the Enlightenment the idea of taste explicitly became associated with not just the actual taste of something, which had always been considered an indicator of whether food was good or bad (nourishing foods generally tasted good, spoiled/poison foods tasted bad), but a general discrimination against bad things while supporting an inclination toward good.
Of course taste has always been subjective, a matter of culture and socioeconomic status. It's entirely for one to have a sense of taste accepted by his peers, yet looked down upon by those above him while simultaneously being considered effete and pretentious by those beneath him.
In recent times two competing sensibilities of taste have become dominant: European bourgeois and American pop culture. When it comes to food, or just about anything else you could apply the term taste to some synthesis of the two is what's in play.
What's the point of delicious food? For most of history delicious meant nourishing. With the advent of artificial flavorings we can make anything delicious, the same way pop culture can make the inane seem profound. So perhaps it's time for a reevaluation of the meaning of taste.
tl;dr legit question.
Then why do the longest lived peoples (Okinawans, Mediterranean islanders, etc) also have some of the most flavourful food? "Healthy" isn't about eating boatloads of faddish bullshit like eggwhites, turkey mince and plain brocolli. Try portion control and nutritional variety.
Because not everybody is as autistic as you are.
Considering that fat, salt, and sugar are 80%+ of what makes food taste good and there are unhealthy I'm about ready to give up on food too.
