Sunflower oil can be a healthy option when used at the right temperature. It contains high levels of unsaturated fats, which are used in the body as omega-6 fatty acids, which are vital for regulating metabolism and promoting proper growth and health of skin, hair and bones. Although the body needs omega-6 fatty acids, consuming foods that are excessively high in nutrients can lead to increased inflammation.
This article discusses the compounds in sunflower oil, the best temperatures to reap its health benefits, and its potential effects on the body.

What Makes Sunflower Oil Potentially Harmful?
Sunflower oil can be healthy when consumed carefully and cooked at the right temperature (up to 450 degrees). High heat can cause the oil to release toxic compounds that can negatively affect your overall health.
Omega-6 and High Oleic Content
Omega-6 fatty acids serve a variety of body functions. They include:
- Stimulation of hair and skin growth
- Maintaining proper bone health
- regulate metabolism
- Maintaining the health of the reproductive system
People need about 11-22 grams of omega-6 fatty acids per day to keep the nutrient doing its job. However, most standard Western diets contain much higher levels of these nutrients.
Because of this excess, people who consume too many omega-6 fatty acids put themselves at risk for increased widespread inflammation in the body and conditions that develop with inflammation, such as inflammatory bowel disease (IBD).
Oleic Acid and Your Health
Oleic acid is the culprit behind increased inflammation after consuming too much sunflower oil. Oleic acid is a chemical compound found in animal and vegetable fats and oils. It is often considered a “healthy fat” that can reduce inflammation, fight damage from free radicals, and keep your heart healthy. However, when consumed excessively, the opposite effects may occur. Studies have shown that having too much oleic acid in your diet can negatively affect your heart health, which can lead to heart failure.
Oxidation and Aldehydes
Sunflower oil should not be cooked above 450 degrees as it releases potentially toxic compounds at higher temperatures. The smoke point of an oil is generally considered the cut-off point at which you should use the oil in cooking, as this is where the oil begins to spoil. But research has found that the oil’s smoke point is not directly related to its ability to maintain the integrity of its healthy compounds.
Research has found that cooking oil above a certain temperature releases compounds known as aldehydes. When released into air, aldehydes can be:
Research has also found that DNA damage from excessive aldehyde intake may also play a role in the onset of other serious health conditions, such as Alzheimer’s and heart disease.
What is Smoke Point?
The smoke point assigned to an oil is the temperature at which the oil will begin to burn and produce smoke. The compounds in the oil break down when overheated. It is generally recommended to cook below the smoke point to achieve the best overall effect in terms of flavor and health benefits.
Does Sunflower Oil Contribute to Inflammation?
Sunflower oil is often thought to be able to fight inflammation, but the opposite may also be true. Because of its compounds such as omega-6 fatty acids, consuming too much fat can lead to the release of inflammatory chemicals in the body.
Potential Benefits of Sunflower Oil
Although consuming too much of these dangerous compounds can lead to adverse health effects, including them in moderation in your diet may provide some health benefits. They include:
Comparison of Sunflower Oil and Other Cooking Oils
Many other oils can also be used in the same way as sunflower oil. But no two oils are exactly alike. For example, the smoke point (the temperature at which oil begins to burn) of oils varies greatly from one to the other.
| Different Cooking Oils and Smoke Points | |
|---|---|
| Oil Type | Smoke Point (Grade F) |
| Sunflower oil | 450 |
| coconut oil | 350 |
| olive oil | 325 to 375 |
| avocado oil | 520 |
| canola oil | 375 to 450 |
| grape seed oil | 420 |
| peanut oil | 450 |
| Almond oil | 430 |
| safflower oil | 475 to 500 |
| linseed oil | 225 |
| Sesame | 410 to 450 |
Is Olive Oil Better?
Olive oil has a lower smoke point than sunflower oil and therefore should be cooked at a lower temperature. However, since olive oil is more likely to remain stable at higher temperatures than sunflower oil, it is considered a good option to use in cooking for its health benefits.
Both oils contain “good” fats that can benefit your overall health. Saying that one oil is better than the other does not paint the right picture, because while one may be better than the other for certain types of cooking, both have healthy properties when consumed in moderation.
How to Tell How Much Hot Oil Is?
You can tell if the oil is hot enough to fry food by placing a wooden spoon in the pan. If bubbles appear around the spoon and rise to the surface, the oil is hot enough. It is best to heat the oil slowly to avoid reaching its smoke point.
Who Should Stay Away From Sunflower Oil?
Consuming sunflower oil is generally safe and offers some health benefits. However, when consumed in very high amounts, its pro-inflammatory effects may be harmful to someone with a disease or disorder that triggers chronic inflammation.
Obese people may also want to limit their sunflower oil intake because diets high in fat may contribute to worsened health outcomes in this group.
Summary
Sunflower oil may be a healthy choice for some when consumed in moderation. However, cooking foods too much or too often can lead to pro-inflammatory effects in the body. Its health benefits, such as lowering “bad” cholesterol levels, can be great for those looking to combat certain issues associated with a high-fat diet.
When cooking with sunflower oil, consume it in moderation to reap its health benefits without putting your body at risk of increased inflammation.
