The oils you use in cooking can affect your health in both the short and long term. While oils might seem like a small part of your meals, they actually play a big role in your well-being, from supporting your heart to helping control inflammation in your body.
In fact, the oils you use daily can either nourish or disrupt your body's natural balance. When you’re grocery shopping, it's important to be mindful of how the oils you pick affect your health — and your cooking.
With a little knowledge, you can make smarter decisions that benefit your health, taste buds, and cooking skills. Below are the healthiest oils for cooking!
Choosing Healthy Oils to Cook With
When choosing healthy oils, it’s important to check their processing method, additives, nutritional benefits, and smoke point. Here’s what to keep in mind:
Processing Method
How an oil is processed impacts its quality and nutrition. Some oils are made using heat or solvents, which can strip away nutrients and add impurities. This includes processes like bleaching and deodorizing ❶. Additionally, chemical refining can lead to pollution, as it produces waste materials that harm the environment.
Choose oils labeled "cold-pressed" or "expeller-pressed." These methods avoid high heat and chemicals, keeping the oil’s natural nutrients and flavor intact.
Additives
Additives may be used to extend shelf life or enhance appearance, but they can affect the oil’s purity.
A bigger concern is food adulteration, where cheaper oils are mixed with premium ones without proper disclosure. This practice not only lowers the nutritional value of the oil but can also harm your health. To avoid this, buy from trusted brands and check for labels like "100% pure" or "unadulterated."
Nutritional Benefits
Omega-9 fatty acids, such as oleic acid, are classified as monounsaturated fats. Choose oils high in omega-9 to support heart health. These fats can raise good cholesterol (HDL).
Also, pick oils with low saturated fat, as too much saturated fat may harm your heart. Oils with oleic acid are generally considered healthier than saturated animal fats ❷.
Smoke Point
The smoke point is the temperature at which oil begins to break down and produce harmful compounds. When cooking at high temperatures, like deep frying, roasting, or grilling, it’s important to choose oils that can handle the heat without burning.
Oils with a higher smoke point stay stable and safe to ensure your food cooks properly without creating toxins.
What are the Healthiest Oils to Cook With?
Let’s take a closer look at some of the healthiest oils to keep in your kitchen, so you can feel good about every meal you prepare.
Algae Oil
Algae oil is a great choice for a healthy cooking oil. Extracted from microalgae, it has more omega-9 fatty acids than both olive and avocado oils. These healthy fats help lower bad cholesterol and support heart health. Algae oil also has 75% less saturated fat and much less omega-6 fat, which can cause inflammation if consumed in excess. This makes it a better option.
Algae oil is also perfect for high-heat cooking. It has a high smoke point of about 535°F, which is 125°F higher than olive oil. This means it’s great for high-heat cooking like frying, roasting, and grilling.
Plus, algae oil is five times more stable than avocado oil, so it won’t break down into harmful compounds when heated.
Algae oil is pure and free from seed oils, glyphosate, and hexane. It is third-party tested to ensure it is safe and clean. With its neutral taste and many benefits, algae oil is a top choice as an all-purpose oil in your kitchen.
Extra Virgin Olive Oil
Extra virgin olive oil (EVOO) is rich in monounsaturated fats and antioxidants, which help reduce inflammation and lower the risk of heart disease.
It is minimally processed, meaning it is made by cold-pressing olives without using heat or chemicals. This preserves its natural nutrients and enhances its flavor, which is typically rich, fruity, and slightly peppery.
EVOO has a lower smoke point of 325-400°F, so it’s best for low-heat cooking, dressings, or drizzling on dishes. Its strong flavor is great for salads and roasted vegetables.

Avocado Oil
Avocado oil is derived from the pulp of avocados, primarily from varieties like Hass, which are known for their rich oil content. Unlike many cooking oils that are extracted from seeds, avocado oil is pressed from the fruit itself, giving it a unique composition of nutrients and healthy fats ❸.
With a smoke point of 350-400°F, avocado oil makes a suitable oil for high-heat cooking, such as frying, roasting, and grilling.

Coconut Oil
Coconut oil is high in saturated fats, especially medium-chain triglycerides (MCTs), which are quickly turned into energy. While it can be part of a balanced diet, its high saturated fat content means it should be used in moderation.
Virgin coconut oil has a smoke point of around 350-380°F, while refined coconut oil can handle up to 450°F. This makes coconut oil great for baking, sautéing, or adding flavor to tropical and sweet dishes.

Butter
Butter is high in saturated fats and has vitamins A, D, and E. Since it has a lot of saturated fat, it’s best to use butter in moderation. With a low smoke point of about 300°F (150°C), butter works well for baking, low-heat sautéing, or adding flavor to dishes at the end.
Unhealthy Cooking Oils You Should Avoid
Avoid cooking oils that are high in omega-6 fatty acids, as they can cause inflammation when consumed in excess. These oils can disrupt the balance between omega-6 and omega-3 fats in the body, which can contribute to heart disease and other health issues.
Some oils also become unstable at high cooking temperatures. They break down and create harmful compounds. Oils to avoid include:
- Soybean oil
- Corn oil
- Sunflower oil (regular)
- Safflower oil
- Cottonseed oil
- Partially hydrogenated oils (trans fats)
- Grapeseed oil
- Rice bran oil
- Vegetable oil blends (mixtures of two or more vegetable oils)
The Bottom Line
The oils you choose can make a significant impact on your health and the quality of your meals. Opting for minimally processed oils with the right balance of healthy fats can help you support your heart, reduce inflammation, and create meals you feel good about serving to your family and friends.
