Trying to find the healthiest cooking oil can be a daunting task. One one hand, you want to cook with an oil that has a high flash (smoke) point, but you also need to use a cooking oil that has a healthy balance of Omega 3 to Omega 6 fatty acids--and even better if the oil is loaded with antioxidants and vitamins! Knowing the smoke point of oils is important because heating oil to the point where the oil begins to smoke produces toxic fumes and harmful free radicals. Check out our healthiest cooking oil comparison chart below to help alleviate the confusion!
Considerations: for high temperature cooking, select cooking oils with a high smoke point. For low temperature cooking, or adding to dishes and salad dressings, chose oils with a higher Omega-3 fatty acids since they promote healthy cells and decrease stroke and heart attack risk. They are also known for their anti-inflammatory action. Although you need Omega-6 fatty acids to maintain cell wall integrity and provide energy for the heart, too much Omega-6 fatty acids can increase inflammation in the body. Also, cooking oils high in Omega 9 is a good way to go. Omega-9 fatty acids are considered to be "conditionally essential," which means that although your body produces them, they aren't produced in meaningful quantities. Consuming omega-9 fatty acids such as oleic acid lowers the risk of heart attacks, arteriosclerosis, and aids in cancer prevention.
The bottom line is that when possible, buy and use organic, unrefined, cold-processed vegetable oils. Use extra virgin olive oil in salads or to add to cooked foods, but not for high temperature cooking. Unrefined walnut oil is also good, but again only for low temperature uses.
You can use virgin coconut oil (high in beneficial saturated fats and medium chain triglycerides) for most mid-temperature cooking. However, coconut oil has a smoke point of about 350 degrees F (171 C), which means it is not suitable for high temperature cooking. Other choices include virgin olive oil and even butter in small amounts.
Use avocado oil for high temperature cooking. Avocado oil has a very high smoke point by comparison to other cooking oils. It will not burn or smoke until it reaches 520 F (271 C), which is ideal for searing meats and frying in a Wok. Another good cooking oil is rice bran oil 495 F(257 C). Again, look for organic, cold-processed oil.
