4 scientific benefits of extra virgin olive oil

Extra virgin olive oil (EVOO) has been a staple of Mediterranean cuisine for centuries, and its health benefits have been well-documented in scientific literature. Recent studies have shown that EVOO has various health benefits, including reducing the risk of heart disease, improving cognitive function, and preventing certain types of cancer. In this article, we will explore the scientific benefits of extra virgin olive oil, backed by scientific sources.

  1. Reduces the risk of heart disease

Heart disease is the leading cause of death globally, and a healthy diet plays a vital role in preventing it. Research suggests that consuming EVOO can reduce the risk of heart disease. A study published in the New England Journal of Medicine showed that a Mediterranean diet supplemented with EVOO reduced the incidence of major cardiovascular events by 30% compared to a low-fat diet. Moreover, EVOO has anti-inflammatory and antioxidant properties that help to reduce the oxidative stress that contributes to heart disease.

  1. Improves cognitive function

Cognitive decline is a natural part of aging, and it can lead to dementia and Alzheimer's disease. However, some studies have shown that consuming EVOO can help to improve cognitive function. A study published in the Journal of Alzheimer's Disease showed that consuming EVOO as part of a Mediterranean diet was associated with improved cognitive function in older adults. EVOO contains oleocanthal, a compound that has been shown to reduce the buildup of amyloid plaques in the brain, which are associated with Alzheimer's disease.

  1. Prevents certain types of cancer

Cancer is a complex disease that can have multiple causes. However, research has shown that EVOO can help to prevent certain types of cancer. A study published in the Annals of Oncology showed that consuming a Mediterranean diet supplemented with EVOO reduced the risk of breast cancer by 68% compared to a low-fat diet. EVOO contains polyphenols, which have been shown to have anti-cancer properties. Moreover, EVOO has been shown to induce apoptosis (programmed cell death) in cancer cells, which can prevent their proliferation.

  1. Reduces inflammation

Inflammation is a natural response of the immune system to injury or infection. However, chronic inflammation can contribute to the development of many chronic diseases. EVOO has anti-inflammatory properties that can help to reduce inflammation. A study published in the Journal of Nutrition showed that consuming EVOO reduced the levels of inflammatory markers in the blood of healthy adults.


Extra virgin olive oil is a nutritious and healthy food that has been used for centuries in Mediterranean cuisine. Its health benefits have been scientifically proven, and it can help to reduce the risk of heart disease, improve cognitive function, prevent certain types of cancer, and reduce inflammation. If you want to enjoy the health benefits of EVOO, make sure to choose a high-quality product from a trusted source.
