You probably have a bottle of sunflower or canola oil in your kitchen. These oils are commonly used for cooking or salads around the world. But recently, seed oils have been in the spotlight for the wrong reasons. Some people in social media claim they are toxic and harmful to health. They’ve even labeled them “the hateful eight”, targeting oils like canola, corn, cottonseed, grapeseed, soy, rice bran, sunflower, and safflower.
So, are seed oils truly harmful, or are these concerns exaggerated?
Much of the criticism comes from the fact that seed oils are high in omega – 6 fatty acids. These are essential fats that our bodies need but cannot produce. Some believe omega-6 causes inflammation, which is linked to heart disease and other health problems. However, recent studies say otherwise.
Research shows that omega-6 fats actually create helpful anti-inflammatory compounds in the body. A large study involving over 200,000 people over 30 years found that those who consumed more plant oils were less likely to die from heart disease or cancer. In contrast, higher butter intake was linked to a higher risk of death.

Another key point is that linoleic acid, a type of omega-6 fat found in seed oils, has been shown to lower bad cholesterol levels. Studies have found that people with higher levels of linoleic acid in their blood had a lower risk of heart disease.
Some argue that having too much omega-6 compared to omega-3 is a platform. While the average Western diet may have a high omega-6 to omega-3 ratio, experts suggest it’s better to increase omega-3 intake rather than cut omega-6. Both offer health benefits when balanced.

One concern about seed oil is how they’re made. Most are processed using chemicals like hexane. But after processing, these substances are removed. Cold – pressed oils avoid chemicals, but they are more expensive. While these processed foods have been linked to health problems, the risks usually come from excess sugar, salt, and additives – not the oils themselves.
Experts agree: Seed oils are not the enemy. Used in moderation, they offer several health benefits. Whether added to a salad or used in cooking, they can be part of a healthy lifestyle.
