It’s a matter of what you are used to. I cut out most processed foods a decade ago and work hard at making good food from scratch. Now if I eat something made with bullion instead of homemade broth it tastes bad to me. Likewise store bought or baked goods from a mix are something I just can’t eat. We don’t eat much cereal as I usually make breakfast, but even my kids prefer kashi to fruit loops ;-). It’s what your taste buds are accustomed to eating.
My foods aren’t flavorless, just less flavors from esters (organic chemistry lab on that is what started the process to eliminate artificial ingredients).
I cut out processed foods too, mainly because of the high nitrate and sodium content.
