If you’ve spent some time on health and wellness tiktok or instagram, you’ve probably heard people warn you to throw your seed oils right away – or otherwise.
Influencers claim that they are toxic, inflammatory and even blame for America’s obesity crisis. But is there any science behind fear that monitors?
We asked dietitians to check some of the most viral claims about seed oils and help you make informed choices.
Requirements # 1: Seed oils are “toxic” and causing inflammation
You may have heard that seed oils – such as sunflower, soybean, saplor or corn oil – are harmful because they are full of “toxins” that cause inflammation. But according to MyFitnessPal Dietistian Brookell White, this idea doesn’t hold up.
“Seed oils get a bad rap,” she says. “They have high omega-6 polyunsaturated fats, which are actually important-we need them for brain development, metabolism and overall growth (1).”
Although it is true that omega-6 fat can lead to the formation of arachidonic acid, a compound associated with inflammation, your body converts only a small amount. Actually Studies show that diets with omega-6 fatty acids can help lower cholesterol and improve heart health (5).
What is more likely to drive inflammation? Ultra-processed foods that happen to contain seed oils, along with added sugar, sodium and saturated fat. “There is strong evidence that the reduction of ultra-processed food supports better health,” says White (2). “But that doesn’t mean that seed oils used in homemade homes or whole foods are the problem.”
Requirements # 2: Seed oils were invented as industrial products
Yes, this family of oils has industrial uses. But that doesn’t mean they don’t belong in your kitchen.
White explains that Seed oils were originally extracted using a mechanical screw press, an innovation of the 1880s that made oil production more efficient (6).
Today, these oils are used not only in food but also in environmentally friendly products such as soaps and cosmetics. It’s not a red flag – it’s actually a benefit to sustainability (7).
What about chemical treatment? Some people care about the use of solvents such as hexane during refining. But White emphasizes that any residue in the final oil is minimal and regulated.
The bigger problem, she says is what happens when seed oils overheat and reuse repeatedly (Ahem, just like in deep -freeeers at restaurants) because it can lead to oxidation and harmful compounds (5).

Requirements # 3: Seed oils are responsible for the increase in obesity
This one sounds simple, but the truth is far more complicated.
“While seed oils often owe to rising obesity rates, other factors probably play a greater role“Says Lauren Cuda, a dietitian with MyFitnessPal.” Diet with high content of ultra-processed foods and many contains seed oils associated with poor health results, but not only because of the oils. These foods also contain many calories, added sugar and low fiber and nutrients (8). “
In other words, it is not the canola oil in your homemade vinaigrette. The problem is the combination of low nutrient, packed foods with high calorie that can contribute to weight gain.
When people reduce seed oils, it is often part of a wider dietary change that includes eating fewer processed foods. This is what drives the weight loss results that people sometimes get by eliminating seed oils. It does not cut oils alone that make the rush.
Requirements # 4: Seed oils are full of “oxidized” fats that destroy your cells
Seed oils contain polyunsaturated fats (PUFAs), which can be sensitive to heat, light and air. But that doesn’t mean they destroy your cells (9), (3).
“The idea that seed oils are harmful due to oxidation is misleading,” says MyFitnessPal dietitian Katherine Basbaum. “They also contain antioxidants such as vitamin E, which help prevent oxidative stress in the body. In fact, eating these oils in appropriate amounts can actually help protect your cells“She adds (10).
Basbaum recommends keeping your oils in a cool, dark place. And when cooking, don’t warm them beyond their smoke point. But used correctly, these oils do not pose the oxidative risk that some online voices suggest (11).
Requirements # 5: Fat like butter, ghee, beef parlor or coconut oil is always healthier
This claim often comes up with the idea that “natural” fats are better than “processed”. But when it comes to your heart health, Saturated fat content means more than trends on social media.
“Fats like butter, ghee, beef and coconut oil are all in saturated fat,” says Basbaum. “And Excess saturated fat has been linked to increased risk of heart disease and higher mortality (12). “
On the other hand have unsaturated fats – like those found in olives, avocado and rapeseed oil – shown to reduce Risk of heart disease (13).
This does not mean that you can never cook with butter or enjoy coconut oil in a recipe. But making unsaturated fat for your standard choice for daily cooking supports long -term health.
And remember: No single ingredient manufactures or breaks your diet. “Health is about your overall eating pattern,” says Basbaum. “It means aiming for more fiber, fruits and vegetables and less added sugar, sodium and saturated fat – while still enjoying the foods you love.”

The lower line
These Oils may be a social media scapegoat, but science tells a different story. They are a source of essential fats that your body needs and are not in the nature of the case harmful. The real health risks come from ultra-processed foods-not the oils themselves.
While it is smart to be aware of how to store and cook with oils, there is no need to fear seed oils in your salad dressing or stirring. Instead of falling for viral nutrition myths, focus on your overall dietary pattern: more whole foods, fewer ultra -processed and a balanced blend of healthy fats.
