DeepSummary
The podcast episode discusses the emerging trend of doctors prescribing healthy foods like vegetables and entire meals to patients as a form of preventive medicine. Marin McKenna, a science journalist, explains how programs like the one in Flint, Michigan, provide vouchers for produce to families with the goal of improving nutrition and reducing disease risk factors like high cholesterol and diabetes.
While the enthusiasm for food as medicine is growing rapidly, McKenna notes that there is limited evidence so far on its effectiveness in measurable health outcomes. However, some studies have shown positive effects like reduced hemoglobin A1C levels, lower blood pressure, and decreased body mass index with food prescription programs.
More rigorous research is planned, with organizations like the American Heart Association funding new projects to evaluate the impact of prescribing healthy food. The goal is to transition from merely advising patients to eat better to providing specific interventions that facilitate access to nutritious meals and groceries.
