The Mediterranean diet
The Mediterranean diet stands as a renowned model of healthy eating, citing numerous health benefits. An abundance of fresh fruit and vegetables, whole grains, nuts, and seeds characterizes the diet. It also includes moderate fish and poultry consumption and low to average intake of dairy products.
A central part of a Mediterranean diet is olive oil, the consumption of which has been recognized for its health benefits for many years. The golden oil contains antioxidants and monounsaturated fats, particularly heart-healthy oleic acid and polyphenols, associated with reduced risk of chronic diseases.
Its use in cooking, dressings, and even drizzled-over finished dishes helps explain the low rates of heart disease and extended lifespans observed in Mediterranean regions.
The role of olive oil
Olive oil is considered a healthy fat due to its rich content of monounsaturated fats, primarily oleic acid, and antioxidants, notably vitamin E and phenolic compounds.
Monounsaturated fats help improve cholesterol profiles, lowering “bad” LDL cholesterol and supporting “good” HDL cholesterol. The antioxidants combat oxidative stress and inflammation, reducing the risk of chronic diseases like heart disease, cancer, diabetes, and neurodegenerative conditions.
Extra virgin olive oil, with the highest antioxidant and monounsaturated fat levels, is the healthiest option. This unique composition makes olive oil a valuable choice for a heart-healthy and overall health-conscious diet.
Nutrients in olive oil
Olive oil is rich in essential nutrients, notably vitamin E and polyphenols. Vitamin E is a potent antioxidant that protects cells from oxidative damage, reducing the risk of chronic diseases and supporting skin health.
Polyphenols, on the other hand, have various health benefits. They possess anti-inflammatory and antioxidant properties, helping to combat oxidative stress and inflammation.
These compounds are linked to improved heart health, better brain function, and a decreased risk of certain cancers. You can access these key nutrients by incorporating olive oil into your diet and potentially enjoy their protective effects against various health issues.

Heart-healthy benefits
Numerous studies have indicated an inverse relationship between olive oil consumption and cardiovascular disease (CVD) risk. For instance, research in Spain and Italy has demonstrated that regular olive oil intake is linked to a decreased risk of coronary heart disease, cardiovascular mortality, and all-cause mortality.

In Italian populations, survivors of myocardial infarction and elderly individuals who consumed olive oil regularly exhibited a lower risk of mortality. While there is consistent evidence supporting the association between olive oil consumption and a reduced risk of stroke, findings related to coronary heart disease have been somewhat inconsistent.
It’s worth noting that the type of olive oil matters, with extra virgin olive oil (EVOO) having higher polyphenol levels, potentially offering additional cardiovascular benefits beyond its impact on lipid profiles.
Some studies have also suggested a potential role for olive oil in cancer prevention, notably regarding breast cancer, although the evidence remains less conclusive.
Fighting inflammation
The anti-inflammatory properties of olive oil, particularly its phenolic compound oleocanthal, have piqued scientific interest and offer the potential to prevent chronic diseases.
Oleocanthal, found in virgin olive oil, mimics the anti-inflammatory actions of Ibuprofen. Recent studies have indicated that it could play a role in mitigating diseases such as joint degeneration, neurodegenerative disorders, and specific types of cancer.
