New Study Links Regular Olive Oil Consumption With Key Cognitive Health Benefit.
Summary
- Regular (daily) consumption of a quality extra virgin olive oil has been linked to 28 percent lower risk of dying from dementia, new study says.
- Replacing about one teaspoon of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8 to 14 percent lower risk of dying from dementia.
- Olive Oil contains oleocanthal, a compound known for its ability to clear the brain of beta-amyloid plaques and tau tangles—hallmarks of Alzheimer’s disease.

New Study Links Daily Olive Oil Intake With Reduced Risk Of Dying From Dementia
Regular consumption of quality extra virgin olive oil has been linked to a significantly reduced risk of dying from dementia, according to a new study.
A study published in JAMA Network Open found that consuming at least a half tablespoon of olive oil every day was associated with a 28 percent lower risk of dying from dementia, as compared with those who never or rarely consumed olive oil.
The observational study led by researchers at the Harvard T.H. Chan School of Public Health examined two groups of U.S. health professionals and found daily olive oil consumption is associated with a lower risk of dying from dementia.
Other highlights from the study, as reported in The Washington Post include:
- Participants who reported more olive oil consumption had a lower risk of dying from dementia, regardless of the quality of their diet or their adherence to the Mediterranean diet, which consists of plenty of fresh fruit, vegetables, whole grains, nuts and moderate amounts of fish and poultry.
- Researchers found replacing about one teaspoon of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8 to 14 percent lower risk of dying from dementia.
- The study observed two cohorts of more than 92,000 male and female U.S. health professionals over 28 years. Roughly 65 percent of the participants were women. And 4,751 of the participants died of dementia during the study period.
The Science Behind Extra Virgin Olive Oil and Brain Health
Olive oil, a staple of the Mediterranean diet, has long been celebrated for its heart-healthy benefits. Its rich content of monounsaturated fats, antioxidants, and anti-inflammatory properties make it a superfood. However, it’s the link to cognitive health that’s currently captivating the scientific community.
Research suggests that regular consumption of olive oil could significantly reduce the risk of dying from dementia. This connection is primarily attributed to oleocanthal, a compound found in extra virgin olive oil, known for its ability to clear the brain of beta-amyloid plaques and tau tangles—hallmarks of Alzheimer’s disease.
Furthermore, the phenolic compounds present in olive oil have shown promise in protecting the nervous system and enhancing the autophagy process, where cells break down and remove toxins and debris. This mechanism is vital for preventing the accumulation of harmful substances in the brain, which can lead to cognitive decline.
Incorporating Extra Virgin Olive Oil into Your Daily Regimen
Adopting a lifestyle that includes daily olive oil consumption doesn’t require a complete dietary overhaul. Here are simple yet effective ways to make olive oil a constant in your nutrition plan:
- Switch to Olive Oil for Cooking: Replace other fats like butter or vegetable oil with olive oil for a healthier alternative.
- Salad Dressings: Olive oil makes an excellent base for dressings. Mix it with vinegar and your choice of herbs for a nutritious and tasty salad dressing.
- Drizzle Over Prepared Foods: A drizzle of olive oil can enhance the flavor profile of both hot and cold dishes, adding a rich texture and depth.
- Mindful Consumption: While olive oil is beneficial, it’s also high in calories. Moderation is key to reaping its health benefits without unwanted weight gain.
Combining Mediterranean Diet With Exercise For Cognitive Health
The growing body of evidence supporting the health benefits of olive oil echoes a larger truth—the potential of traditional diets in combating modern diseases. The Mediterranean diet, in particular, emphasizes whole foods, lean proteins, and healthy fats, offering a blueprint for a balanced and nutritious eating pattern that supports long-term health and cognitive function.
While the prospect of reducing dementia risk through dietary choices is encouraging, it’s essential to approach this information as part of a broader lifestyle strategy. Regular physical activity, mental exercises, and a balanced diet all play critical roles in maintaining cognitive health.
The conversation around olive oil and its protective effects against dementia is far from over, but it’s an exciting development in the ongoing exploration of nutrition and brain health. By making informed dietary choices today, we can take proactive steps towards preserving our cognitive function and overall well-being for years to come. Health enthusiasts, aging individuals, and nutrition seekers are encouraged to stay tuned to emerging research in this field. After all, the key to unlocking a healthier, more vibrant future may very well lie in the simplicity of our daily dietary choices.
