What I don't get is in my text it says for noncountable food items, we use de la, du, or de l' but only for certain verbs like prendre, boire, manger, etc. For others we use le, la, les. But what if the verb is manger but the food is countable?

Salut, Michelle. Could you give me examples of what you see? What is the name of your textbook, the publisher, author? If I'm familiar with your text, it will be easier to help you.

Do you mean, by countable, un pain (a loaf/piece of bread)?

Il mange de la soupe. = He's eating (some) soup.

Il mange la soupe. = He's eating (the) soup.
