One of the common money myths I hear from people all of the time is, "It costs more to eat healthy." The reality, though, is just the opposite.

Sure, you can spend a lot to eat healthy, but you can also spend a ton of money on a very unhealthy diet. I've always noticed that the food we should be eating the most of (according to the good old USDA) — things like grains, legumes, fruits and veggies — happen to cost less on a per-pound basis than the food that's bad for us, at least in large quantities (red meat, fatty dairy products, processed foods, etc.).

Of course there are exceptions, but as a general rule, when you eat lower on the food chain, you have a healthier and more affordable diet.

With that in mind, I started keeping a running list of healthy foods I've found for under $1 per pound at supermarkets near where I live, in the Washington, D.C., area, which happens to be one of the most expensive places to live and shop in the U.S. Now, before you accuse me of being a "cheap-fake" rather than a "cheapskate," let me be clear: Not all of the foods on this list can be found everywhere, at all times, for under $1 per pound (although some nearly always can).

Quite a few items on this list were special sale items (aka "loss leaders"), and scoring many of the fruits and vegetables on this list for under a buck a pound means buying them when they're in season. And, no, you're not likely to find any organically raised foods costing under $1 a pound — but most Americans would have a dramatically improved diet simply by eating more of the foods on this list, organic or not.

So forget this crazy talk about it costing more to eat healthy and adopt my motto instead: "For a healthy diet year round, shop for foods at under $1 a pound."

51 Healthy Foods That Cost Less Than a Buck a Pound

1. Apples

Not such a forbidden fruit after all, when you can find them on sale — particularly in the fall.

When they start to turn brown, peel and freeze them, then thaw slightly and mash them up to make a delicious, healthy mock ice cream.

This superfood is the perfect nutty substitute for rice or risottos in any dish. Plus, it barley costs anything.

Dried beans are always the best value, but canned beans are still a great deal.
