We always use olive oil for cooking, we use it for curries and stirfrying instead of clarified butter or other oils.
But recently I read it has a low smoking point which means the good stuff in it is destroyed at a lower temperature and lots of toxic free radicals are released. I read it’s only good for you uncooked or at a lower temp.
Is this true? What are other healthy cooking oils?
to get the benefits out of olive oil, you have to eat it uncooked, as a salad dressing or bread dip. once it warms up, it loses all of the good stuff and you might as well save some money and use sunflower or canola oil.
Heating an oil changes its characteristics. Oils that are healthy at room temperature can become unhealthy when heated above certain temperatures. When choosing a cooking oil, it is important to match the oil’s heat tolerance with the cooking method.[24]](Cooking oil - Wikipedia).
A 2001 parallel review of 20-year dietary fat studies in the United Kingdom, the United States of America and Spain[25]](Cooking oil - Wikipedia) concluded that polyunsaturated oils like soya, canola, sunflower and corn degrade easily to toxic compounds when heated up. Prolonged consumption of burnt oils lead to atherosclerosis, inflammatory joint disease and development of birth defects. The scientists also questioned global health authories’ wilful recommendation of large amounts of polyunsaturated fats into the human diet without accompanying measures to ensure the protection of these fatty acids against heat-and oxidative-degradation.
Palm oil contains more saturated fats then canola oil, corn oil, linseed oil, soybean oil, safflower oil, and sunflower oil. Therefore, palm oil can withstand extreme deepfry heat and resistant to oxidation compared to vegetable oils of high unsaturated fats.[26]](Cooking oil - Wikipedia) Since the turn of the century, palm oil is increasingly incorporated into the global commercial food industry because it remains stable when deepfried or baked in extreme high heat[27]](Cooking oil - Wikipedia)[28]](Cooking oil - Wikipedia) and for its high levels of natural antioxidants.[29]](Cooking oil - Wikipedia)
Oils that are suitable for high-temperature frying (above 230°C/445°F) because of their high smoke point include:
