Telawaa: No Such Word As "Junks"

On TELAWAA(The English Language Academy With Ayo Alonge).

Right under my nose, an instructor said:

"You should eat more of fruits than junks".

So, what's wrong with her expression?

Caution:
In English, there is no such word as "junks". What you call "junks" is actually "junk".

Even when you refer to a lot of chocolates, candies, cake and the rest, it is still called "junk", please take note.
