Diet is one of the factors most strongly related to cardiovascular disease, which is the leading cause of death globally and entails large costs on healthcare systems worldwide. Dietary interventions based on a Mediterranean dietary pattern are known to reduce the incidence and mortality from cardiovascular disease(1), but the financial benefits of those interventions are unclear.
Increasing the percentage of population adhering to a Mediterranean diet would produce important annual cost savings to healthcare systems, according to a recent study which applies a relatively new technique that allows greater precision in estimating the monetary value of healthy eating habits(2). Specifically, the authors calculated that increasing by 20% the percentage of people adhering a Mediterranean dietary pattern would produce annual savings in cardiovascular-related cost by $8.2 billion in the U.S. and $0.32 billion in Canada. As expected, if the percentage of the population adhering to a Mediterranean dietary pattern increased further, for example, to 80%, the savings would also be greater ($31 billion in the U.S. and $1.2 billion in Canada).
