Julie says, “If it’s your health, and it’s going to make you feel better, it’s worth it.” She uses the zero conditional.
The zero conditional is used to talk about general truths, or things that are almost always true under certain conditions. For example, it’s pretty much always true that if it rains, stuff gets wet.
The zero conditional is easy to form because all the verbs are in present tense. You just use two clauses, one with If + simple present verb and the other with another simple present verb, as in, “If students miss an exam, the professor fails them.” Or you can reverse the order of the clauses. You can say, “The professor fails students if they miss an exam.”
