Healthiest Stir-Fry Oils Both canola oil and olive oil are low in unhealthy saturated fats and high in healthy monounsaturated fats. Scientists believe monounsaturated fats help to lower bad cholesterol (LDL) which can clog arteries and lead to heart disease or strokes.
Olive oil and avocado oil are good choices for deep frying. Peanut and palm oils are less suitable, either for health or environmental reasons.
With a smoking point of 450F, refined sunflower oil is also good for stir-frying. It is light tasting as well. Grapeseed oil is also great, especially if its flavor is neutral; grapeseed oil's smoking point is roughly 420F. Rice bran oil is another wonderful oil to cook with but it is not well distributed.
The bottom line
Some of the healthier cooking oils that can withstand higher cooking temperatures include olive oil, avocado oil, sesame oil, and safflower oil. Plus, they contain various unsaturated fatty acids, antioxidants, and other compounds that may offer health benefits.
The oils which should be avoided for cooking are oils like soybean, corn, canola, sunflower, and safflower. These oils have unstable fats and will decimate the nutritional properties of your food.
Sunflower and canola oil are some the best choices for sautéing and stir-frying. They contain heart-healthy fats, have a mild flavour and are not expensive. Other good choices for high-heat cooking include light olive oil, sesame oil and rice bran oil. Use spray oils as much as possible to limit adding extra calories.
The Winner: Coconut Oil
Coconut oil also has powerful health benefits. It is particularly rich in a fatty acid called Lauric Acid, which can improve cholesterol and help kill bacteria and other pathogens ( 2 , 3, 4).
Choose plant-based oils rich in unsaturated fat.
The heart association suggests the following cooking oils, which meet its health standards: canola, corn, olive, peanut, safflower, soybean and sunflower, as well as specialty oils like avocado, grape-seed and sesame.
Using a wok or large frying pan, heat sesame oil over medium-high.
Steer clear of olive oil, delicate finishing oils (like nut oils), or butter, which will all burn, smoke, and become rancid quickly. This one goes hand-in-hand with the previous mistake. For perfectly cooked meat, tofu, tempeh, and/or vegetables, you want to make sure that the pan is not crowded.
The healthiest type is extra-virgin olive oil (EVOO). It can help lower your blood pressure and fight inflammation. It lowers your risk of heart disease by improving the health of your blood vessels and preventing blood clots. EVOO is also loaded with antioxidants, which ward off cell damage.
Heart-healthy oils like canola, corn, olive, peanut, and sunflower oils contain monounsaturated and polyunsaturated fats. They help to lower harmful low-density lipoprotein (LDL) cholesterol and raise healthy high-density lipoprotein (HDL) cholesterol.
If you are looking for a diet to lose weight, you must pick a cooking oil that has the least amount of saturated fat in it. Coconut and canola oils are your best bets.
Both of them have relatively good levels of vitamin E, which helps defend against free radical damage. However, olive oil is higher in vitamin K, which helps contribute to blood clotting and strengthens bones. Because of this, olive oil has an edge when it comes to nutritional value.
As far as your health is concerned, more evidence supports the benefits of olive oil over canola. Robust research links olive oil — especially extra virgin — to health benefits, including for your heart. It's less refined and boasts more antioxidants than canola oil, which makes it a better choice.
“Fish and chips need to be cooked in an oil with an animal fat base,” said Susman. “Frytol is the number one brand. If you want to use a vegetable oil for health reasons then you might as well go and eat a poke bowl.”
Best oil for pan frying
Since such a small amount of oil is used, any high-heat oil like canola, peanut, sunflower, or safflower oil will work for this application.
Sunflower oil is best when using a deep fryer and will result in crispy chips and batter, which means it's ideal for your ActiFry as well. On top of this, sunflower oil has been found to keep your skin clear, strengthen your immune system and keep your heart healthy, so it's worth adding to your diet.
Monounsaturated Fats
According to MayoClinic.com, consuming MUFAs improves your blood cholesterol levels, reduces your risk of heart disease and may help stabilize blood sugar levels. Foods high in monounsaturated fats include olive, canola, sunflower and sesame oils, avocados, pecans, almonds, salmon and herring.
Olive oil has a lower smoke point-the point at which an oil literally begins to smoke (olive oil's is between 365° and 420°F)-than some other oils. When you heat olive oil to its smoke point, the beneficial compounds in oil start to degrade, and potentially health-harming compounds form.
First of all, it can be expensive. Plus, it has a relatively low smoke point, which, according to food scientist Harold McGee, is the "temperature at which a fat breaks down into visible gaseous products." That breakdown can ruin the taste of foods.
