The Journal reported Sunday that policy makers are trying to determine whether “food as medicine” programs can enhance health and also save money, the outlet said:

A growing body of research suggests that addressing food insecurity can improve health as well as deliver savings by reducing medical visits, the need for medication, or by helping control serious illness. The programs have also appealed to some GOP lawmakers who believe states should have more control over their Medicaid programs.

…

Tapping medical funds for food programs has raised objections from some who say it is an unnecessary expansion of Medicaid. The Supplemental Nutrition Assistance Program, or SNAP, already helps people on lower incomes pay for food, these people say.

According to the American Society for Nutrition (ASN), the concept of “food as medicine” is between nutrition and healthcare.

“It may take many forms, including medically tailored meals, medically tailored groceries, and produce prescription programs,” the society’s website read, adding, “Evidence suggests food as medicine can work.”
