Olive oil has distinct flavor and taste. Unlike many other oils, which are extracted from nuts and seeds, the olive is obtained from the olive berries and hence, carries large amounts of plant-derived anti-oxidants, phyto-sterols, and vitamins.
Olive oil is recognized as one of the healthiest edible oils since it contains less saturated fats. Additionally, it composes linoleic (omega-6) and linolenic acid (omega-3) essential fatty acids at a recommended 8:1 ratio.
The oil is high in calories. Its high-calorie content chiefly comes from its fats. However, it is especially rich in mono-unsaturated fatty acids (MUFA) like oleic acid (18:1) and palmitoleic acid (16:1) that help in lowering LDL or "bad cholesterol" and to increase HDL or "good cholesterol" in the blood. Research studies suggest that Mediterranean diet which is rich in monounsaturated fatty acids help to prevent coronary artery disease and strokes by favoring healthy blood lipid profile.
