The USDA uses national food intake data and grocery price information to calculate different costs for a healthy diet at home. The latest numbers for a four-member family: a thrifty food plan, $146 a week; a low-cost food plan, $191 a week; a moderate-cost plan, $239; a liberal plan, $289 a week. Some food waste is built into these costs.
"We constantly hear the claim that you can't eat healthy on a budget, and to us that's a myth because a family can eat a healthy diet with fruits and vegetables that meets the Dietary Guidelines for Americans," says Robert Post, associate executive director of the USDA's Center for Nutrition Policy and Promotion.
$146 to $289 a week for a family of four. Does that sound right to you?
