What was the mainstay of the annex diet in Anne frank?

Yes , but there was little food and she had many of the same dishes repeatedly.

Victor Kugler, Johannes Kleiman, Miep Gies, Jan Gies, Johannes Hendrik Voskuijl, and Bep Voskuijl were the only people who knew of the people in hiding, and were their "helpers" for the duration of their confinement, bringing food, news of the war, and other things they needed.
