350⁰ - 410⁰ F while olive oil and light-tasting olive oil have a smoke point that ranges from 390⁰ - 470⁰ F. Canola, Sunflower, Soybean, Corn and Peanut oils have smoke points that range from 350⁰ - 450⁰ F. Solid at room temperature fats such as butter, coconut oil and lard have smoke points of 300⁰ - 350⁰. Any heating of olive oil destroys all the good, so your extra virgin oil will transform into normal oil similar in properties with other vegetable products. Coconut oil is having a bit of a moment, despite being in the much hated ‘saturated fat’ camp, but actually has a LOWER smoke point than olive oil so is still only suitable for low heat cooking. A group whose report was published in the Journal of Agricultural Food Chemistry heated olive oil … Olive oil contains tiny amount of water so it takes a lot of … Does olive oil lose its health benefits when heated?

Overheating also creates harmful free radicals. On the other hand, oleic acid, sterols, squalene, and triterpenic alcohols (erythrodiol and uvaol) and acids (oleanolic and maslinic) were quite constant, exhibiting a high stability against oxidation. Olive Oil Retains Health Benefits During Cooking, Vegetables Cooked in Extra Virgin Olive Oil Retain More Nutrients. The claims range from the heat producing everything from carcinogens contained in the smoke created by heating, to conversion to trans-fats. (Source:  https://www.ncbi.nlm.nih.gov/pubmed/17935291), A similar study was published in 2012 in Food Chemistry. The study found that extra virgin olive oil performed better than sunflower oil. It is interesting to note that no one ever says not to cook with butter or coconut oil due to their low smoke points.
