The Best Oils for Cooking

Choosing the right oil can make all the difference in your cooking, from flavour to health benefits. With so many options out there, it can be hard to know which oils work best for different dishes and cooking methods.

Smoke Point

Choosing the right oil for high-heat cooking is key to preserving both the flavour and nutritional value of your food. When oils are heated past their smoke point, they can break down and produce harmful compounds like free radicals. Free radicals are unstable molecules that can cause oxidative stress and inflammation in the body, which can lead to various health issues over time.

Oils for High-Heat Cooking

Oils with a high smoke point are ideal for high-heat cooking methods like frying, stir-frying and searing. Here are some of the best oils for high-heat cooking:

• Avocado oil has a smoke point around 520°F (271°C). Avocado oil is rich in monounsaturated fats, particularly oleic acid. These fats are good for heart health since they can help lower LDL (bad) cholesterol while raising HDL (good) cholesterol. The monounsaturated fats and antioxidants in avocado oil, like vitamin E, also have anti-inflammatory effects.

• Canola oil has a smoke point around 400°F (230°C). Canola oil contains omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which have anti-inflammatory properties. It's also low in saturated fat and rich in monounsaturated fat, both good for cardiovascular health.

• Refined olive oil has a smoke point around 465°F (240°C). While refined olive oil contains fewer antioxidants than extra virgin olive oil, it still has compounds that can help reduce inflammation in the body. It keeps some of the health benefits of extra virgin olive oil while being more stable at high heat.

• Refined coconut oil has a mild flavour and a high smoke point, making it a versatile option for various cooking methods without giving dishes a strong coconut taste.

Oils for Dressings and Salads

Oils with a lower smoke point are best for preparations that involve little to no heat, like salads, vegetables or dressings. Here are some of the best oils for low-heat use:

• Extra virgin olive oil has a smoke point of about 375°F (191°C), though it varies depending on quality. This oil is rich in monounsaturated fats, particularly oleic acid, known to improve heart health. Extra virgin olive oil contains a variety of bioactive compounds, including oleocanthal and polyphenols, which have powerful anti-inflammatory effects. The polyphenols and healthy fats in this oil are believed to help protect brain cells and improve cognitive function.

• Flaxseed oil and almond oil have a smoke point of about 225°F (107°C). Flaxseed oil is rich in alpha-linolenic acid (ALA), an omega-3 fatty acid that can help lower LDL (bad) cholesterol and has anti-inflammatory properties. Almond oil is well known for its skin benefits thanks to its high vitamin E content. Vitamin E is a powerful antioxidant that can protect skin from oxidative stress, improve skin hydration and reduce signs of aging.

• Walnut oil has a smoke point around 300-350°F (149-177°C). The omega-3 fatty acids in walnut oil have anti-inflammatory properties and can help lower LDL (bad) cholesterol and improve overall heart health.

Conclusion

By choosing oils with smoke points suited to your cooking methods, you not only improve the taste and texture of your dishes, but also protect your health by minimizing the production of harmful compounds. For cooking, avocado oil has the highest smoke point, making it a great choice for frying, sautéing, baking and searing. Extra virgin olive oil is arguably one of the best oils to use regularly in salads thanks to its proven health benefits.
