The current “Food As Medicine” movement harkens back to the adage “Let Food be Thy Medicine,” attributed to Hippocrates, yet maybe even the ancient Greeks sometimes wondered, ‘sure, but which foods?’ Fruits and vegetables, whole grains and lean proteins, aka, the cornerstone of the U.S. Dietary Guidelines, is now the usual answer, yet many experts believe that Americans, especially those of low socio-economic means, don’t have the knowledge or resources to follow this advice. For Food-As-Medicine advocates, one solution is to improve access, mainly to fruits and vegetables, by delivering free food— directly to people, in their homes.

The concept is championed by a powerhouse alliance of top-rank government, public health and industry actors. Rooted in a long history, the current movement started in about 2018, with a “Food As Medicine” working group on Capitol Hill. This led to a 2022 White House conference on Hunger, Nutrition & Health, resulting in a report recommending “food as medicine interventions for people with diet-related diseases.” In that same year, the Aspen Institute published its first “Food is Medicine” action plan, with a heady list of advisors. There’s also been “Food as Medicine” summits occurring nationwide since 2021. I (NT) have written with some skepticism about these efforts since the food industry has been central to virtually all of them.

From a scientific perspective, though, there’s the not-so-small problem that the Food-As-Medicine concept has barely been tested, and the few randomized, controlled clinical trials (RCTs) to date have yielded mixed results. This dearth of evidence was acknowledged in the 2022 Aspen report; An effort to get Congress in 2023 to spend $2 million on a “Food As Medicine” pilot program failed.
