There was a day last week that I could taste. It's pretty rare and seems to happen maybe when general inflammation is down, my allergies are more at bay, and the barometric pressure or whatever it is aligns and then, behold, I can REALLY taste things despite a nine-times-broken nose, and all the allergy and sinus problems. It is kind of glorious, and it helps me understand why people like eating food.
Normally, food is something I eat because there are nutrients and stuff in it, and it fuels me. If it tastes like blah all the time, that's actually kind of convenient. I can eat healthier food that may not taste great (and might thus be cheaper). If I could taste well, maybe I wouldn't go near it.
On that most recent tasting day, I was in the big cafeteria at work (not the mini version we have in our building), and I had some food that was amazing. (Those green beans! That chicken fajita wrap full of peppers and onions! Droooool.) So sometimes food tastes amazing. Thanks be to God.
