Healthy Cooking Oils: Best Uses and Benefits

With the wide variety of cooking oils available, choosing the right one can be intimidating. The key to choosing healthy cooking oils lies in understanding that each one has its own specific culinary and nutritional benefits. This primer on cooking oils explains the basics that will help you choose the best oils for you and your family’s meals.

Cooking Temperature

Just like the other ingredients in your recipe, your choice of oil depends on what you’re making and how you plan to cook it. The smoke point, or temperature at which an oil burns and smokes, varies with each oil. When you heat an oil beyond its smoke point, its nutritional value and flavor can break down. In some cases, it can even generate toxins and free radicals. For this reason, you should only use medium-to-high smoke-point oils for higher-temperature recipes and low smoke-point oils for raw foods or drizzling over salads. The table below outlines the smoke-point categories of common cooking oils.

Smoke-point categories of common cooking oils:[1][2][3]

High smoke-point oils	Almond, avocado, sunflower, soybean, peanut, corn, canola	High temperature cooking, such as searing and browning
Medium smoke-point oils	Refined olive oil, grapeseed, coconut, sesame, extra virgin olive	Light sautéing, sauces, baking
Low smoke-point oils	Flaxseed, walnut, wheat germ	Finishing oils or no-cook, dressings, dips

Nutritional Value

Even though plant oils are healthy, they are still a condensed source of fat and calories. Be sure to use them in moderation. While most contain around 120 calories and 14 g of fat per tablespoon, it is the proportions of monounsaturated, polyunsaturated, and saturated fats that differentiate them.[4]

Monounsaturated and Polyunsaturated Fatty Acids

Monounsaturated and polyunsaturated fatty acids are the main fats found in the majority of plant-derived oils. These fats are considered healthy. Sources include:

• Olive oil
• Almond oil
• Canola oil
• Sesame oil
• Safflower oil

Omega-3 Fatty Acids

Omega-3s are a type of polyunsaturated fatty acid that are essential to maintaining overall health, including heart health.* Ensure your daily diet includes omega-3s by consuming more oils that contain omega-3s, including:

• Hemp oil
• Pumpkin seed oil
• Walnut oil
• Organic cold pressed flaxseed oil

Saturated Fats

Saturated fats are controversial. While usually considered unhealthy, saturated plant oils with high concentrations of medium-chain triglycerides (MCTs), such as coconut oil and red palm oil, are healthy exceptions.

Oil Quality

Choosing which oil to buy can be tricky, but it will become much easier once you understand the terminology used on common product labels. This is also an important part of knowing how much you need to spend to get the quality you want.

Extra Virgin Oil and Virgin Oils

Extra virgin oils are unrefined and extracted from high-quality fruit or seeds without using chemicals or heat. This may be done with a press, decanter, or screw press at a low temperature, making them the highest quality oils available. Virgin oils are extracted in a similar way but with a slightly lower quality fruit or seed, making them the second highest quality.[5] In general, the more refined an oil is, the lower is its nutritional value and the more stable it becomes for cooking at high heats.

Cold Pressed Oils

Cold pressed oils are extracted from fruits or seeds using a press and without the use of heat. This process helps retain more of the flavor, aroma, and nutrients. It can be used to make extra virgin and virgin oils.

Storing Oils

An oil that becomes oxidized will go rancid and should not be used. You can spot a rancid oil by its “off” smell and taste. To maintain the quality of your cooking oils and help prevent them from becoming oxidized, store them in dark glass bottles, away from light, and in a cool location.
