Meal
Diet, Dining
noun, verbal noun
A regular eating occurrence is also known as a meal.
食事 can refer to a specific meal, like breakfast, lunch, or dinner. It can also mean your overall diet, like the kinds of foods you usually eat. 食事 can even be a verbal noun for the act of dining, so 食事する can be used to talk about having a meal.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.

Three meals a day is not enough.
今食事中なので、後でまた電話しますね。
I'm having a meal now, so I'll call again later.
