That's not uncommon at all, It's kind of like the smoker who after quitting is amazed at how much better food taste & smells. When you quit or really cut back on all the fatty, salty & processed foods your taste will improve. I went through a similar thing 3 years ago when I made a concerted effort to eat better. Now I eat foods that I never would have thought to eat & always seek out new, healthier foods to try.
