"le / la / les" v "du / de la / des" when the noun has no article in English

In the question Aurélie mange ___________ , with the translation Aurélie eats bread, the answer Aurélie mange le pain is marked as wrong in favour of Aurélie mange du pain. But surely Aurélie mange du pain means Aurélie is eating some bread, and Aurélie eats bread means that she eats bread in general, so should therefore be translated as Aurélie mange le pain.
