Avoiding highly palatable foods for two days can shift preference back to bland foods.

“those highly savory foods or I think they call them highly palatable foods are making more bland foods, whole foods, meaning foods that aren't processed. It's making those tastes less good at least for a while. And all it takes is a short period of time, even just days, two days or so of not consuming any highly palatable foods and suddenly broccoli with just a little bit of seasoning tastes delicious to you.”
