Over 28 years of research involving more than 90,000 adults in the U.S., a study published in the JAMA Network Open has found that consuming just a spoonful of olive oil a day may lower the risk of dying from dementia by 28%. The study, which assessed olive oil intake and dementia-related deaths, suggests that incorporating olive oil into your diet could improve vascular health, reduce inflammation, and enhance cognitive function. This blog post probes into the findings of the study, highlighting the potential benefits of olive oil in preventing dementia-related mortality.
So let’s dive into this intriguing new information, shall we?
The Study: Understanding the Research
Methodology: Assessing Intake of Olive Oil Intake and Dementia Risk
A study published in the JAMA Network Open observed over 90,000 adults in the U.S. for 28 years to analyze the relationship between olive oil consumption and dementia risk. Olive oil intake was assessed every four years using food frequency questionnaires.
Participants: Demographics and Health Status
Assessing the demographics and health status of the participants, the study included 65% females, with a mean age of 56 at the beginning. They were all free of cardiovascular disease and cancer. The research involved female participants from the Nurses’ Health Study and male participants from the Health Professionals Follow-Up Study from 1990 to 2018.
Findings: The Link Between Olive Oil and Dementia Risk
Reduced Risk: The Impact of Daily Olive Oil Consumption
Any intake of olive oil can significantly lower the risk of dying from dementia, as shown in a study observing over 90,000 adults. Consuming more than seven grams of olive oil a day was linked to a 28% lower risk of dementia-related death compared to those who rarely consumed olive oil.

Mechanisms: How Olive Oil May Protect Against Dementia
Vascular Health: The Role of Olive Oil in Cognitive Function
The study suggests that olive oil may lower the risk of dementia mortality by improving vascular health. Olive oil is believed to help attenuate inflammation, oxidative stress, and restore blood-brain barrier function, thus potentially enhancing cognitive function. Consuming more than seven grams of olive oil a day was associated with a 28 per cent lower risk of dying from dementia compared to those who rarely consumed olive oil.
Anti-Inflammatory Effects: Attenuating Oxidative Stress and Restoring Blood-Brain Barrier Function
One of the key mechanisms through which olive oil could protect against dementia is its anti-inflammatory effects. Olive oil is believed to attenuate oxidative stress and restore blood-brain barrier function, which are crucial factors in maintaining cognitive health. By substituting margarine and mayonnaise with olive oil, individuals could potentially reduce their risk of dementia-related mortality by 8 to 14 per cent.
Vascular health plays a significant role in cognitive function, and the consumption of olive oil may contribute to maintaining optimal vascular health and potentially reducing the risk of dementia-related mortality. The study highlighted that the anti-inflammatory effects of olive oil, including attenuating oxidative stress and restoring blood-brain barrier function, may have a positive impact on cognitive function. By choosing olive oil and other vegetable oils as dietary options, individuals may enhance their overall health and potentially lower their risk of dementia mortality. It seems, however, that olive oil is the most protective so don’t go crazy with the other oils.
Final Words
On the whole, the findings of the study suggesting that consuming olive oil could lower the risk of dying from dementia are significant. While the study acknowledges that more research is needed to establish a causal relationship, the potential benefits of olive oil in improving vascular health and cognitive function are promising. Incorporating olive oil and other vegetable oils into one’s diet may be a simple yet impactful way to support overall health and potentially reduce the risk of dementia-related mortality.
