Can you eat healthy for a dollar a day?

Is it possible to eat for a dollar a day? Sure, with a little creativity and a lot of planning. But here's a more important question -- is it possible to eat healthy on a dollar a day?

You've probably noticed that the cheapest things in the grocery store or mall food court are the unhealthiest things -- items like potato chips, candy bars and deep-fried whatevers will run you far less at the till than things like fresh organic produce, salads and lean cuts of meat. One couple, trying to live on the dollar-a-day diet, is finding that out the hard way.

"We're used to eating some type of vegetable with every meal and fruit every day. Finding out there was very little way to fit that into our budget, that was a huge struggle," says Kerri Leondard of One Dollar Diet Project in the New York Times. You can read more about her struggle here.

What do you think? Is it possible to eat well on a really tight budget?
