Olive Oil Composition & Analysis

Olive oil is the most studied edible oil due to its numerous health benefits and unique chemical composition. (Extra) Virgin olive oil is made through solely mechanical means, without high temperature or solvents, resulting in a product that is rich in antioxidants and flavors. Many studies have shown the consumption of olive oil improves cardiovascular health (Olive oil as medicine 1; PDF 112 KB), (Olive oil as medicine 2; PDF 104 KB), cancer prevention and inflammation reduction.
