The Everyday Staple That Could Help You Live Longer
As we age, the quest for longevity and youthful vitality becomes increasingly important, with scientific evidence pointing to a simple kitchen staple as a potential key: olive oil. Renowned for its place in the heart-healthy Mediterranean diet, this common ingredient is now linked to a significantly longer lifespan and improved skin health, according to comprehensive research.
Scientific Evidence for a Longer Life
A major 2020 study published in the Journal of the American College of Cardiology provided compelling evidence for olive oil's life-extending properties. The research, which analysed the diets of approximately 90,000 people over 28 years, discovered that consuming just half a tablespoon of olive oil daily led to a 14% reduced risk for heart disease.
The findings were even more striking for mortality rates. The study concluded that participants who consumed the most olive oil had a 19% lower risk of dying from cardiovascular causes compared to those who consumed the least. The research paper stated, "Higher olive oil intake was associated with lower risk of total and cause-specific mortality."
Furthermore, the study highlighted that replacing less healthy fats like margarine, butter, mayonnaise, and dairy fat with olive oil was associated with a lower overall risk of death.
Why Olive Oil is a Nutritional Powerhouse
Healthline has described extra virgin olive oil as "one of the healthiest oils on earth," and for good reason. It is rich in healthy monounsaturated fats, particularly oleic acid, and contains valuable minor components like vitamin E and polyphenols.
These compounds contribute to its potent anti-inflammatory and antioxidant properties, which help reduce inflammation and oxidative damage caused by an imbalance of free radicals in the body. A diet rich in olive oil has been consistently linked to a lower risk of chronic diseases, including heart disease, type 2 diabetes, metabolic syndrome, and certain types of cancer.
Radiant Skin and a Stronger Barrier
The benefits of olive oil extend beyond internal health to visible external effects. The nutrients we consume can directly impact our skin's appearance, and olive oil, with its high content of omega-3, omega-6, and omega-9 fatty acids, is particularly beneficial.
These essential fatty acids help to moisturise the skin and strengthen its protective barrier, potentially leading to a more radiant, youthful complexion. The antioxidants present not only boost skin health but also contribute to the well-documented cardiovascular advantages.
While the British Heart Foundation praised the large-scale study for its long duration and participant number, it noted that the lifestyles of the participants—all American nurses and health professionals—might not be fully representative of the wider population. Nonetheless, the evidence strongly positions olive oil as a simple, powerful addition to a health-conscious diet.
