If you spend any time on Tiktok or Instagram on health and wellness, you may hear people warning you to throw away seed oil immediately or something.
Influential people claim they are toxic, inflammatory, and even blame the obesity crisis in the United States. But is there science behind fear?
We ask nutritionists to fact-check some of the most harmful claims about seed oil and help you make informed choices.
Claim #1: Seed oil is “toxic” and causes inflammation
You may have heard that seed oils (such as sunflower, soy, safflower, or corn oil) are harmful because they are full of “toxins” that cause inflammation. But, according to MyFitnesspal dietitian Brookell White, the idea doesn’t end.
“Seed Oil’s rap is not good,” She said. “They are rich in omega-6 polyunsaturated fats, which is actually essential – we need them for brain development, metabolism, and overall growth (1).
Indeed, omega 6 fat can lead to the formation of arachnoid acid, a compound associated with inflammation, but your body only converts small amounts. In fact, High dietary content of omega-6 fatty acids can help lower cholesterol and improve heart health (5).
What is more likely to drive inflammation? Super processed foods that happen to contain seed oil and added sugar, sodium and saturated fat. “There is strong evidence that lowering superprocessed foods can improve health,” White (2) said. “But that doesn’t mean that seed oil used in home cooking or whole foods is the problem.”
Claim #2: Seed Oil is Invented by Industrial Products
Yes, this oil family has industrial uses. But that doesn’t mean they don’t belong to your kitchen.
White explained this Seed oil was initially extracted using mechanical screw presses, an innovation from the 1880s that boosted oil production. (6).
These oils are used today not only in food, but also in environmentally friendly products such as soap and cosmetics. That’s not a red flag, it’s actually a sustainability benefit (7).
What about chemical processing? Some people are worried about using solvents such as hexane during refining. But White stressed that any residue in the final oil is minimal and regulated.
The bigger question, she said, is what happens when the seed oil overheated and reused repeatedly (Oh, like a restaurant fryer) because this can lead to oxidation and harmful compounds (5).

Claim #3: Seed Oil Responsible for Increased Obesity
This sounds simple, but the facts are much more complicated.
“While seed oil is often accused of rising obesity rates, other factors may play a bigger roleLauren Cuda said he is a dietitian and has Myfitnesspal. “Diet in the diet, many of which contain seed oils, are associated with poor health, not just because of oil. These foods also have high calories, added sugars and fiber and nutrients (8).
In other words, this is not the canola oil in your homemade vinegar. The problem is the combination of low-nutrition, high-calorie packaged foods that can lead to weight gain.
When people reduce seed oil, it is often part of a wider dietary change, which includes eating less processed foods. This is what drives weight loss causes people to sometimes get from eliminating seed oils. This is not a separate oil that will solve the problem.
Claim #4: Seed Oil is Full of “oxidized” fat that destroys cells
Seed oil contains polyunsaturated fats (PUFAS) that can be sensitive to heat, light and air. But that doesn’t mean they are destroying your cells (9), (3).
“The idea that seed oils are harmful due to oxidation is misleading,” said MyFitnessPal nutritionist Katherine Basbaum. “They also contain antioxidants, such as vitamin E, which helps prevent oxidative stress in the body. In fact, eating these oils in the right amount may actually help protect your cells,” she added (10).
Basbaum recommends keeping your oil in a cool dark place. Do not heat them outside the smoke point while cooking. But correctly used, these oils do not pose a risk of oxidation as suggested by some online sounds (11).
Claim #5: Fats like butter, ghee, beef beef or coconut oil are always healthier
This statement usually carries the idea that “natural” fat is better than “processed” fat. But when it comes to your heart health Saturated fat content is more important than social media trends.
“Fats like butter, ghee, beef beef and coconut oil all contain saturated fats,” Basbaum said. Excessive saturated fat has been linked to increased risk of heart disease and higher mortality (12). ”
On the other hand, unsaturated fats (such as those found in olives, avocados and canola oils) have been proven reduce Heart disease risk (13).
This doesn’t mean you will never cook with butter or enjoy coconut oil in recipes. However, the default choice for making unsaturated fats for daily cooking supports long-term health.
Remember: There is no ingredient that makes your diet produce or disrupts your diet. “Health is about how you eat holistically,” Basbaum said. “This means pursuing more fiber, fruits and vegetables, as well as less added sugar, sodium and saturated fat – although still enjoying the food you love.”
