“Anti-hunger experts have long argued that the Thrifty Food Plan’s metrics are out of date with the economic realities most struggling households face. They say the plan, formulated in the 1960s, was designed when many American families still had only one working parent, allowing the other parent more time for labor-intensive, but cheap, cooking from scratch. In the past two decades, more working families are made up of two wage earners or a single parent, leaving less time for soaking beans and simmering stews,” The Post’s Laura Reiley reports.
