Below, we summarize Dariush Mozaffarian’s presentation:

The concept of food as medicine is not new, but it has gained new momentum in recent years under the leadership of Professor Dariush Mozaffarian. According to the professor, food can become a fundamental pillar for the treatment and prevention of chronic diseases worldwide.

The health and food crisis

Mozaffarian begins his presentation by highlighting the irony of how, usually, we only think about the negative aspects of food – such as salt, sugar and fats – when in reality, the insufficiency in the consumption of healthy foods is what contributes most to the burden of disease in the world. In the United States, tens of billions of dollars are being invested in state, government, and private programs to fund food for patients in need.

Professor Mozaffarian points out that the food groups that are most deficient in our diets are precisely those that we should consume the most: fruits, vegetables, nuts, seeds, legumes and whole grains. These foods are essential for preventing chronic diseases such as diabetes, obesity, and cardiovascular disease. On the other hand, they also represent a higher risk for distributors and farmers, due to their higher cost, greater susceptibility to spoilage and lack of stable markets to sell them regularly, compared to raw materials to make processed foods.

Delving into the interaction between agriculture and health, Mozaffarian points out the importance of creating consistent and reliable markets for these healthy agricultural products. He argues that, without a stable market, farmers have little reason to grow these crops, thus perpetuating the cycle of poor nutrition and its consequences on public health. This integrative approach aims to improve individual nutrition while supporting the agricultural economy, closing the loop between food production and consumer health.

This approach reflects a vision where the solution to the global health crisis requires a fundamental change in how we perceive and structure our food and health systems, focusing more on prevention through nutrition and less on intervention through medication.

Innovations in the Health System

Dariush Mozaffarian’s presentation highlights the increasing integration of diet as part of medical treatment into the U.S. health care system, an initiative he describes as one of the most promising innovations in modern health care. The concept behind “Food as Medicine” is relatively straightforward, but profoundly transformative: doctors and other health care providers can prescribe food, similar to drugs, which are then funded by the health system for periods that can extend several months or more, depending on the patient’s health conditions and socioeconomic situation.

This approach is being implemented on a large scale through significant investments from state, government, private insurance, and corporate health systems. Mozaffarian indicates that tens of billions of dollars are being allocated to finance these food programs, evidencing a serious and expansive commitment to the concept.

Beyond the mere prescription of food, the movement towards food as medicine also contemplates the delivery of fully prepared and medically adapted meals, which are designed to meet specific nutritional needs based on particular health conditions such as kidney function or sodium needs, for example. This modality facilitates access to healthy food for the sickest patients, eliminating additional barriers such as transportation and access, since this food is delivered directly to the patients’ homes.

The impact of these innovations is tangible, with studies underway across the country examining their efficacy in populations with specific conditions such as type 2 diabetes and high-risk pregnancies. This research seeks to improve the health of individuals and reduce overall health care costs, proposing a model in which improved health and reduced health expenditure go hand in hand.

This progressive, evidence-based approach is positioning the United States at the forefront of integrating nutrition into health care, offering a model that could be replicated globally, with the potential to radically transform how societies address chronic disease through diet.

Global Expansion and Education

The expansion of the concept of “Food as Medicine” is not limited to the United States. During his presentation, Dariush Mozaffarian highlights how this initiative has begun to capture the attention and interest of other countries, pointing to a global movement towards the integration of nutrition into health systems. In Australia, for example, Mozaffarian mentions that they have established collaborations with The George Institute for Global Health, where they are implementing similar programs of nutrition as medicine. In addition, groups in Canada have shown interest and are beginning to explore the implementation of these programs. Even the UK Treasury has contacted the Food is Medicine Institute to discuss the possibility of adopting these practices in its own healthcare system.

Education also plays a crucial role in this expansion. Although currently only a few medical schools in the United States have integrated culinary medicine and nutrition programs into their curricula, the movement is gaining traction. Mozaffarian points to two significant developments in this area. First, a resolution from the U.S. Congress urging that all medical training programs, from medical school to residency and continuing medical education programs, integrate nutrition education into their curricula. Although not a law, this resolution sets forth a strong recommendation supported by potential financial consequences for institutions that do not comply with it. In line with this resolution, major accrediting agencies in the United States have begun to take concrete action. At a recent summit hosted by these agencies, the importance of nutrition education was discussed, resulting in a commitment by one of the leading agencies to make nutrition education mandatory in all residency and fellowship programs starting with its next major update in 2026. This decision marks a significant shift in medical education and promises to prepare future doctors with the tools needed to integrate nutrition into their patients’ care.

This educational approach also extends to specific culinary and nutritional intervention programs, including cooking workshops and patient education videos. These teach patients about the importance of a healthy diet, and give them the practical skills to prepare nutritious meals, thereby increasing adherence to healthy diets and improving long-term health outcomes.

Challenges and future prospects

One of the most significant challenges is the potential resistance of the pharmaceutical industry. Mozaffarian notes that while pharmaceutical companies have so far remained relatively quiet, they are likely to oppose it if nutrition and lifestyle programs start to keep patients away from expensive drugs, especially new weight-loss drugs that are gaining global popularity.

In addition, Mozaffarian points out the importance of continuing to promote the adoption of food as medicine at the level of health policies and systems. Although there is a strong movement in the United States, with states such as New York, Massachusetts, and California leading the implementation of these programs, the real challenge lies in ensuring that these initiatives are sustainable and expand to other states and countries. This effort requires a concerted approach in research, education, and policy translation to demonstrate the long-term benefits and return on investment that these interventions can offer.

Another important future perspective is the need to address health equity. Mozaffarian emphasizes that poor nutrition is one of the main causes of health disparities globally. Communities with lower incomes and less education, which have suffered structural oppression and prejudice for decades, tend to have the worst access to healthy food. The focus on food as medicine has the potential to reverse these disparities by specifically targeting the social needs of these vulnerable groups. This involves providing healthy food and ensuring that these foods are accessible and affordable, and that patients receive the education they need to get the most out of it.

Mozaffarian also stresses the importance of long-term prevention. Although the current focus is on treating chronic diseases such as type 2 diabetes and hypertension, there is a growing recognition that a preventative approach is needed from an early age. This implies policies at the population level that promote the availability and consumption of healthy foods from childhood, through school programs and other means. However, this kind of change requires significant commitment from governments and society, as the benefits of prevention can take decades to manifest.

Finally, Mozaffarian notes that the long-term success of food as medicine will depend on collaboration between diverse sectors, including governments, the private sector, nonprofits, and local communities. This collaboration is crucial to overcoming the financial, logistical and cultural obstacles that can arise when trying to implement these programs on a large scale.
