How would I say "Unhealthy cafeteria food" in spanish? Would it be "comida de la cafetería no saludable"?

Are you going to write it with in a sentence or by itself?

By itself...it is a title.

in that case if you are referring to a specific cafeteria like the school's cafeteria it would be "la comida de la cafeteria no es saludable" if not then "la comida de cafeteria no es saludable"

Yes, the translation of "Unhealthy cafeteria food" in Spanish would be "comida no saludable de la cafetería".

To arrive at this translation, you can break it down as follows:

1. Start with the word "food," which is "comida" in Spanish.
2. Next, add the adjective "unhealthy," which translates as "no saludable" or "poco saludable."
3. Lastly, specify that this refers to cafeteria food, which becomes "de la cafetería" in Spanish.

Putting it all together, you get "comida no saludable de la cafetería."
