Let me clarify some fundamental facts.
There are many regional preferences for cooking oils and their use in different parts of the world. The most consumed cooking oils in the world are palm oils (65.15 Million metric tons), Soybean oil (54.59 MMT), rapeseed oil (28.65 MMT), and sunflower seed oil (17.63MMT).
Oils contain saturated fats, polyunsaturated, and monounsaturated fats. Monounsaturated fats are the healthiest. These are cardio-protective, regulate blood sugar, and aid in weight loss.
Saturated fatty acids are mostly solid at room temperature. In contrast, fats that stay liquid at room temperature are full of unsaturated fatty acids. Common examples of cooking fats rich in saturated fatty acids are butter, cheese, dairy products made from whole or reduced-fat milk, cream, beef fat, fatty beef, etc. Vegetable oil examples of saturated fat-rich oil are coconut oil palm oil.
On the other hand, Olive oil is rich in unsaturated fatty acids. Eating foods that contain saturated fats raises the level of cholesterol in your blood. High levels of LDL cholesterol increase the risk of heart disease and stroke.
In food, exclusive olive oil seems to offer significant protection against cardiac health diseases, irrespective of various clinical, lifestyle, and other characteristics. (Kontogianni et al., 2007)
Virgin olive oil is associated with higher antioxidant capacity levels in the plasma. A Mediterranean-style diet rich in virgin olive oil showed a reduction of cardiovascular disease risk and weight reduction. (Razquin et al., 2009)
After reviewing existing data, the European Food Safety Authority released a claim concerning the benefits of ingestion of virgin olive oil-rich food. (Covas et al., 2015) Canola and olive oil were oils used in this 4-week study. Obesity is associated with high blood lipids, fatty liver, and low-grade inflammation. Both MUFA and PUFA have beneficial effects on blood lipids and the inflammatory state. (Kruse et al., 2015)
My research on oils and other nutritional components was done when I was writing my various books, that it is a combination of oils that are best for our health. Olive and canola oils are some of the healthiest options available.
