For those who instinctively reach for extra virgin olive oil (EVOO) in the kitchen, they’re already making a smart choice. Whether drizzled over a fresh salad, used in cooking, or paired with a warm piece of bread, olive oil has been a cornerstone of Mediterranean diets—long associated with promoting health and longevity. Now, new research from Harvard provides even more evidence to support this tradition.
A recent study from Harvard’s Department of Nutrition highlights the significant role olive oil plays in extending lifespan. By substituting other fats and oils with EVOO, individuals may reduce their risk of chronic disease and support overall well-being.
For nearly three decades, Harvard researchers tracked more than 90,000 participants—60,582 women and 31,801 men—who had no prior history of cardiovascular disease or cancer. Every two years, these individuals completed surveys detailing their eating habits, including their consumption of red meat, whole grains, vegetables, nuts, and fats such as margarine, butter, and mayonnaise.
The results were clear: those who consumed more olive oil had a lower risk of death from cardiovascular disease, cancer, neurodegenerative conditions, and respiratory illnesses. Over time, EVOO consumption increased while margarine intake declined, marking a shift toward healthier fat choices.
One particularly compelling statistic from the study revealed that consuming just half a tablespoon of olive oil per day was linked to a 16% lower risk of cancer-related mortality compared to those who consumed little or no olive oil.
Switching from butter or refined oils to EVOO offers a range of health benefits, primarily due to its high concentration of polyphenols—natural compounds with powerful antioxidant and anti-inflammatory properties. However, choosing the right olive oil is key. Authentic, cold-pressed extra virgin olive oil ensures maximum nutritional value and potency.
Here’s how EVOO supports long-term health:
Incorporating EVOO into daily meals is an easy and flavorful way to promote longevity. Whether used in salad dressings, for roasting vegetables, or as a finishing touch on favorite dishes, it’s a simple yet impactful change.
