Olivol

Also known as: Olive Oil, Oleic Acid, Hydroxytyrosol

Overview

Olive oil is a natural oil derived from olives, known for its high monounsaturated fat content, particularly oleic acid, and antioxidant compounds like hydroxytyrosol. It is widely used in culinary applications and as a dietary supplement due to its potential health benefits. Research indicates that regular consumption of olive oil may reduce the risk of certain cancers and improve cardiovascular health. It is a staple in the Mediterranean diet and is generally considered safe for consumption in moderation. Olive oil is available in various grades, including extra virgin, virgin, and refined, each with different levels of purity and flavor profiles. The quality of available evidence supporting its health benefits is high, with numerous systematic reviews and meta-analyses.

Benefits

Olive oil consumption is associated with a reduced risk of cancer, particularly with high intake compared to low intake (RR = 0.69, 95% CI: 0.62–0.77). This benefit is supported by a systematic review and meta-analysis. Additionally, olive oil may have beneficial effects on cardiovascular health due to its high monounsaturated fat content, which can help lower LDL cholesterol levels. These benefits are most pronounced in adults who follow a Mediterranean diet, which emphasizes olive oil as a primary source of fat. Long-term consumption is likely necessary to observe significant health benefits.

How it works

Olive oil's health benefits are primarily attributed to its antioxidant and anti-inflammatory effects, largely mediated by compounds like hydroxytyrosol. These compounds target oxidative stress pathways, reducing cellular damage and inflammation. Olive oil also influences the cardiovascular and immune systems through its monounsaturated fats, which can improve lipid profiles and reduce the risk of atherosclerosis. The oleic acid in olive oil plays a role in these processes, contributing to overall cardiovascular health.

Side effects

Olive oil is generally considered safe when consumed in moderation as part of a balanced diet. Common side effects are rare at typical dietary levels. However, excessive consumption may lead to gastrointestinal upset in some individuals. Allergic reactions to olive oil are rare but possible. There are no significant drug interactions reported at dietary levels. Olive oil is generally safe for most populations, but individuals with specific health conditions should consult with a healthcare provider. High intake may contribute to weight gain due to its caloric density.

Dosage

Moderate consumption of olive oil, typically 1-2 tablespoons per day, is generally recommended for its health benefits. There is no established minimum effective dose for specific health benefits. Excessive intake may lead to weight gain. Olive oil is best consumed with meals to enhance absorption. It is commonly used in cooking or as a finishing oil. There are no known required cofactors for its absorption or utilization.
