How much food did they have in the searcrt annex? was if enough?

The members of the annex didn't starve, but they did have a number of different food shortages. Because of the shortages, they go through "food cycles" where they only eat one type of food. In Section Eight, they are in the midst of a "bean cycle" and there are no vegetables available. The shortage began when the people who sold them illegal food coupons were caught.
