Food is medicine: clinical trials show the health benefits of dietary interventions

Authors: Priya Venkatesan (2024)


Growing evidence shows that dietary interventions can be effective at treating or delaying some diseases, but further trials are needed for wider adoption.

The concept that diet and nutrition can directly affect human health and disease is undergoing a renaissance. A suboptimal, unhealthy diet is known to substantially increase the risk of obesity and non-communicable diseases, such as coronary heart disease and type 2 diabetes, but unhealthy diets can also increase the risk of other health conditions, such as cancer, osteoporosis and cognitive disorders. As Jordi Salas-Salvadó, professor of nutrition and bromatology at the Rovira i Virgili University in Reus, Spain, emphasizes, “Equitable access to healthy foods is one aspect of disease management that I believe is needed.”
