Nutrition and cooking experts agree that one of the most versatile and healthy oils to cook with and eat is olive oil, as long as it’s extra virgin. “You want an oil that is not refined and overly processed,” says Howard. An “extra virgin” label means that the olive oil is not refined, and therefore of high quality. Extra virgin olive oil contains a large amount of monounsaturated fats and some polyunsaturated fatty acids; many studies have linked it to better heart health. Olive oil has a relatively lower smoke point compared to other oils, so it’s best for low and medium-heat cooking.
The term “vegetable oil” is used to refer to any oil that comes from plant sources, and the healthfulness of a vegetable oil depends on its source and what it’s used for. Most vegetable oils on the market are a blend of canola, corn, soybean, safflower, palm and sunflower oils. “Generally I tell people to use olive oil whenever you can instead of a corn or a soybean oil,” says Weinandy. They’re not necessarily bad for you, she says, “but you can get so much more benefit from olive oil.”
This oil is high in vitamin E; one tablespoon contains 28% of a person’s daily recommended intake of the nutrient. It has a high smoke point and doesn’t have a strong flavor, which means it won’t overwhelm a dish. However, sunflower oil contains a lot of omega-6 fatty acids. The body needs them, but omega-6s are thought to be pro-inflammatory, while omega-3s are anti-inflammatory. Consuming too many omega-6s without balancing with omega 3s, could lead to an excess inflammation in the body, so moderation is key
