This is actually very true. Your palate does change once you cut out a lot of over processed, sugary/salty stuff. Every time my brother (for example) takes my SO and I anywhere, or recommends somewhere to us and we try it, it's always some grease bomb with "the best fries" or "the best burgers" and they're really just loaded with salt. And no, this isn't food hate, but that stuff doesn't taste nearly as good as fresh veggies TO ME because of the way my palate has adjusted. The more you eat fresh vegetables and fruits, the more your palate adjusts to like them (I think).
