The potential health benefits of olive oil consumption, particularly within the context of the Mediterranean diet, have been extensively investigated. However, its specific health benefits remain to be confirmed. The aim of the present work is to review the scientific evidence regarding the specific impact of olive oil consumption on human health, including the prevention of cardiovascular disease, cancers, and diabetes mellitus. Ten related meta-analyses were reviewed to this effect. Olive oil consumption was found to be beneficial for several chronic non-communicable diseases (e.g. including cardiovascular disease, breast cancer and type 2 diabetes), whereas there were contradictory findings regarding its impact on several biomarkers. In conclusion, the aggregated evidence supports the assertion that olive oil consumption is beneficial for human health, and particularly for the prevention of cardiovascular diseases, breast cancer, and type 2 diabetes mellitus.
