Ke maʻalili nei ka ʻai. = The food is cooling (getting/becoming cool). Using ke...nei with stative verbs generally means "getting" or "becoming." BTW, "meaʻai" (or mea ʻai) is basically the standard word for "food" rather than just ʻai. Not sure why ʻai has been chosen by DL. If your goal is to actually begin talking to people in Hawaiian, it would be a good idea to get used to saying "meaʻai."
