"She eats bread."
Translation:Elle mange du pain.
Whoever works on the French section of DL seems to have very little understanding of the difference in English (and possibly in French) of being willing to eat something and actually eating some of that thing. Je mange la viande (i am willing to eat meat, I eat meat) vs je mange de la viande (I am eating some meat).
As far as I remember (And it's been a little while since I've done much studying, so if anyone sees something wrong feel free to correct me!) du does refer to an indefinite noun. So if I were going to eat some bread in general (AKA "I am eating bread") it would be "Je mange du pain." However, if you were going to eat a specific piece of bread, say your family left a piece of bread and you're telling them you're eating it (AKA "I am eating the bread") you would use the le form, so "Je mange le pain."
