Adhering to a Mediterranean diet may significantly extend lifespan, according to a new study. The diet, which emphasizes consumption of fruits, vegetables, nuts, olive oil, whole grains, and legumes, is associated with a nearly 25% reduction in the risk of death over a 25-year period.
The study, led by researchers at Harvard and published online on May 31, 2024, in JAMA Network Open, followed 25,315 women with an average age of 55 at the study’s onset. Participants completed dietary questionnaires and provided blood samples for analysis. Researchers examined dietary patterns and measured blood markers related to metabolism, inflammation, insulin resistance, and cardiovascular health. Over the course of the study, nearly 3,900 participants passed away. The causes of death were determined through medical records.
This long-term analysis underscores the potential benefits of the Mediterranean diet in promoting longevity and reducing mortality risk.
