First of all, in foreign countries, people generally don't ask if they eat or not. Because according to the habits of westerners, the question of eating is personal privacy, so it is generally not asked. In the eyes of westerners, if you ask him if he has eaten, the implication is that if you don't eat, I invite you to eat, and they will generally say no (even if you eat, because you can't refuse others' invitation), so I suggest that you generally don't ask. If you must ask, there are several ways to ask.

Did you have breakfast/lunch/dinner?

Have you had breakfast/lunch/dinner?

Do you want something to eat? ? Do you want something to eat?

In fact, this kind of dialogue, as a daily oral communication, does not need to pursue gorgeous words. You should pay attention that most foreigners don't use too flowery words. The ultimate goal of language is communication, so sometimes it may seem inconspicuous, but if you answer it, you will use it properly!
