In French, nouns are seldom used without a determiner. You need a determiner most of the time, unlike in English for example. The question is then to choose the right article: definite, indefinite or partitive.
to eat camembert ↔ manger du camembert
to drink milk ↔ boire du lait
to love chocolate ↔ aimer le chocolat
to have children ↔ avoir des enfants
