E.G: most people never tasted balsamic vinegar, only a mix of regular vinegar with a bit of grapes dust, plus some caramel and flour added to it. Real balsamic vinegar is hard to find and bloody expensive, because the process of making it reduces an entire barel of wine to a bottle.
But we don't need to go that far. I regularly meet children that have never tasted a vegetable or fruit that tasted very good.
It's not their fault they prefer the kit kat. The kit kat taste WAY better than the red plastic clown nose people told them are tomatoes.
But good fruits and vegetable taste awesome. A proper tomatoes can even be eater as-is, like an apple, with nothing on it. A quality olive oil is a feast in itself with some bread and pepper. A nice pomelo has no need to get added sugar to compensate for excess bitterness.
Generally, as more people have access to more food, we also managed to diminush the taste and nutriment it provides.
P.S: this slider format is terrible. I didn't get to the end of the article because of it.
