                                According to a study published in *Proceedings of the National Academy of Sciences*, certain sweet taste cells on the tongue are activated by salt, highlighting our deeply intertwined sensory responses. This reveals just one of many reasons why are humans wired to crave sugar, fat, and salt, a phenomenon rooted in our ancient past.
