It’s hard to argue with a $1 double cheeseburger. Perhaps that’s why so many believe that eating healthy is expensive.

The myth has become so pervasive that everyone from the U.S. Department of Agriculture to health care providers is attempting to dispel it. Now the Environmental Working Group is joining in.

The EWG has combined forces with anti-hunger group Share Our Strength to create a healthy shopping guide for low-income households: “Good Food on a Tight Budget.”

The guide contains lists of “best buys” – those that pack the most nutrition for the lowest cost – in each food group, cooking/shopping tips, recipes, a meal planner and a price tracker.
