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.
Avocado oil contains large quantities of Omega-9 and Omega-3 fatty acids and is particularly high in oleic acid. Unsaturated fatty acids like these have been shown to lower bad cholesterol and the risk of heart disease. This makes avocado oil the healthiest choice when frying.
Additionally, olive oil is mostly composed of oleic acid (Omega-9), a monounsaturated fatty acid that is naturally resistant to oxidation. Multiple peer-reviewed studies have shown that olive oil is the best oil for frying. Olive oil outperformed vegetable, peanut, corn, soybean, sunflower and canola oils.
Corn Oil. Refined corn oil is often used in frying, thanks to its smoke point of 450°. It has a neutral flavor, and is used frequently in commercial kitchens because of its low price point.
Not all fats or cooking oils are unhealthy. In fact, in their natural and unrefined state, fats can be healthy. When possible, Shanahan recommends avoiding or limiting these eight oils: corn, canola, cottonseed, soy, safflower, sunflower, grapeseed, and rice bran oils, which may lead to inflammation over time.
Due to its high smoke point, vegetable oil is the best oil for deep frying. Canola oil and peanut oil are other popular options. While vegetable oil, canola oil, and peanut oil are the most popular oils for deep frying, there are several other oil options you can choose: Grapeseed Oil.
Canola oil:
Considered to be one of the best cooking oil for heart and diabetes, canola oil has zero cholesterol and is rich in vitamin E and K. It also has a higher smoke point and can be used at higher temperatures.
Once in our kitchens, we cook them in our canola-blend oil so you can have them crispy and hot—just the way you like them. Want to hear more about our fry ingredients? Get the down low on how we flavor our fries.
Italians cook pretty much everything with olive oil. We use it to cook, to fry, and to make cakes; we even make ice cream from it (have you tried it?
Highest Smoke Point Oils
Chinese cooks normally use soybean oil, vegetable oil, or peanut oil, all of which have a high smoke point. Peanut oil usually has a pleasant nutty flavor and is suitable not only for stir-frying but also for deep-frying.
Omega-6s are found in oils such as corn, safflower, sunflower, soy and vegetable and products made with those oils. Excess consumption of omega-6s can trigger the body to produce pro-inflammatory chemicals, and the American diet tends to be very high in omega-6s.
The listed products are Rina, Fresh Fri with Garlic Oil, Fry Mate, Tilly, Top Fry, Salit, Gold and Pure Olive Gold, Bahari Fry, and Postman.
Nearly all restaurants use soy, canola, or other seed oil mystery blends as the standard oil to fry up food. Food is better cooked with fats like lard, ghee, butter, tallow, and more.
For cooking, choose refined oils (generally, any plant oil that isn't described as 'virgin' or 'extra virgin' will be refined). These are more stable at high temperatures, and the lower cost and milder flavour mean they're better for frying and roasting.
By most measures, air frying is healthier than frying in oil. It cuts calories by 70% to 80% and has a lot less fat. This cooking method might also cut down on some of the other harmful effects of oil frying.
Aside from high-quality extra virgin olive oil being well suited for deep frying, it's also a great way to impart flavor and keep it healthier. Chef Dory Ford of Aqua Terra Culinary deep fries with extra virgin olive oil because, as he says, “It's a more healthful way of cooking.”
This idea that it's not a good idea to cook over high heat with olive oil is fairly common. For a lot of people, the concern is one of health, specifically that olive oil, with its relatively low smoke point of 325 to 375°F (165 to 190°C), degrades more than other oils when exposed to high heat.
The potatoes we use to make our famous chips generally come from Tassie and Victoria and the high-oleic canola oil we use for cooking them is also Australian-grown.
