I'm not exactly sure what your question is, but I'm sure food stamps are separate from housing. The amount you get is dependent on income and how many people there are in your family.

I received food stamps for three months back in 1982 when I lost my job to the recession then, and it wasn't very much. I took a list and a calculator to try to get the most food value for the price. Then I would get behind a large woman with a bunch of kids and an overflowing basket full of junk food and soda and frozen prepared meals.

There are also Food Banks, that collect food and give it away to people who get food stamps (and maybe others, too), but I think you can only go there a few times a month. But the way things are now (not as good as the news media reports), the food banks are in dire straits due to more demand than they can supply.
