Olive Oil: Key Nutrients and Health Benefits

Nutritional Value & Composition

Olive oil, primarily extracted from pressed olives, is a rich source of healthy fats. "Extra Virgin" olive oil, the most sought-after version of olive oil, is the least processed among edible oil variants. Olive oil is renowned for its health benefits and nutritional value. Here’s a breakdown for this:

• Mono-unsaturated Fats:

These predominant fats in olive oil help reduce inflammation and oxidative stress, potentially decreasing the risk of chronic diseases. Additionally, mono-unsaturated fats are known for their heat resistance, making olive oil a healthy choice for cooking.

• Antioxidants:

Olive oil, especially extra virgin olive oil, is among the richest sources of powerful antioxidants. These natural compounds help protect cells from damage caused by free radicals that lead to the development of chronic diseases. Antioxidants also help lower the risk of heart disease by safeguarding blood cholesterol from oxidation.

• Vitamins:

While not its defining characteristic, olive oil offers a good amount of vitamins, including vitamin E and vitamin K in the diet. Vitamin E contributes to overall health by acting as an antioxidant, while vitamin K plays a vital role in blood clotting and improving bone health.

• Omega-3 and Omega-6 Fatty Acids:

While olive oil is not rich in essential fatty acids, it does contain small amounts of these acids which are important for brain functioon and inflammation regulation.

• Phytosterols:

Olive oil contains phytosterols ( a plant compound that have a structure similar to cholesterol) that can help lower cholesterol absorpotion in the gut thereby contributing to heart health.
