Are Seed Oils Really That Unhealthy?

At SeedOilNews, we help people who are curious about seed oil by collating information and news about seed oils.

Seed oils such as canola, rapeseed (or vegetable oil in the UK), cottonseed, sunflower, safflower and rice bran are often preferred when cooking at home or eating out at restaurants, and can even be found in packaged foods and cosmetic products.
Concerns with these foods arise because of their highly perishable polyunsaturated fat content, which becomes easily oxidized on shelves, in our bodies and over time – leading to inflammation that promotes heart disease, obesity and diabetes.

Are Omega-6 Fatty Acids Actually Bad for You?

Seed oils like canola, corn, soybean, safflower and sunflower are rich sources of omega-6 fatty acids in modern diets. High doses of these omega-6 fats are known to be pro-inflammatory; additionally, they reduce your ability to burn body fat effectively and lower energy levels while increasing the risk of chronic diseases.
Seed oils have come under criticism for containing too much omega-6 fatty acid linoleic acid, and its pro-inflammatory claims are often made based on animal research; other research indicates it doesn’t promote inflammation in humans. However, critics often overestimate its impact and make their claims solely on this basis.
Omega-6 fatty acids are necessary in small doses to support overall good health, yet their ratio with omega-3s matters more when it comes to decreasing inflammation than omega-6s themselves. Unfortunately, most diets contain far too many ultra-processed foods and too few whole, nutrient-dense foods like fish.
Industrial seed oils present another challenge in that they’re refined, meaning they’re exposed to heat and chemicals which may cause them to oxidize or turn rancid, producing harmful by-products which increase risk for heart disease and cancer.
Rancid seed oils deprive your body of vital Vitamin E, essential for healthy skin and eyes. Many experts advise choosing olive, coconut or avocado oils instead.
For maximum vitamin E benefits, select unrefined oils when selecting oil products. Furthermore, add nuts, seeds, and whole vegetables as sources of Vitamin E for additional nutritional support.

Why Should You Beware of Highly Processed Seed Oils?

Social media, podcasts and TikTok can make it easy to become caught up in nutrition fads; one such fad involves seed oils being considered “toxic”, with claims they contribute to heart disease, diabetes, leaky gut and brain fog symptoms.
Some of these concerns are legitimate; others aren’t. Let’s take a closer look at some of these claims:
Seed oils undergo a rigorous refining process in order to transform from their solid form into commercial use, often using heat, chemical additives and solvents such as hexane. Hexane could pose potential health risks when inhaled directly; however, there’s little evidence that small quantities found in cooked seed oils pose any significant threat.
Seed oils’ primary impact is in ultra-processed foods like fries, donuts and chips containing an abundance of ultra-refined carbohydrates containing sodium, sugar and refined carbs that often make people sick or unhealthy. Cutting these out may result in feeling better, but that doesn’t prove that seed oil was at fault.
Many will argue it is essential to select unrefined or cold-pressed cooking and salad oils as they are less processed, yet these options still contain some oxidized, trans, and saturated fats, which have been linked with adverse health outcomes. When choosing these varieties of oils, be mindful that consuming too much can increase inflammation. So when selecting unrefined or cold-pressed seed oils, make sure you pair them with foods high in fiber, antioxidants, and omega-3 fatty acids for the best results. This will help offset some of its adverse health outcomes.

Why Are Seed Oils Sneaking Into Processed Foods?

Seed oils don’t live up to the bad press they receive online; in fact, they’re quite beneficial in cooking healthy meals and as part of a balanced diet. Extra virgin olive oil provides another option which is stable at higher temperatures while rich in antioxidants – make this choice for high heat dishes instead!
One common accusation against seed oils is that they contain dangerous chemicals. One source cites hexane as one such hazardous agent used during processing; however, even trace amounts of this substance don’t pose any threat and should have been cleared off by the time your store receives the oil from us.
Other claims against industrial seed oils involve accusations that they contain chemical additives, trans fats and oxidized byproducts; these allegations, however, are founded upon inaccurate research or misleading marketing campaigns.
Most of the harmful compounds associated with seed oils are actually present in other processed food items; so simply eliminating seed oils from your diet won’t do much to improve its overall health impact. However, doing so might make you feel healthier but won’t actually address underlying problems that contribute to poor health outcomes.
Seed oils have long been linked with obesity and heart disease. While it’s true that they have a higher smoke point than other cooking oils, most of your body’s fats contain saturated and monounsaturated fats which may actually benefit your health.
Problematic seed oil-containing foods often also contain high concentrations of sugar, salt and other additives; additionally they lack any fiber, leading to nutritional deficiencies as well as other potential health concerns.

Are Seed Oils Really as Healthy as We Thought?

Seed oils have come under intense scrutiny recently. A quick search on TikTok will yield videos warning about their alleged toxic nature and negative health implications, but is this really accurate? To gain further insights we contacted several experts for their opinion.
Let’s first consider where this myth may have begun. It’s easy to see where someone could form this misperception: oil used in processed food like fried foods and ultra-processed packaged snacks is certainly no friend of health; however, seed oils themselves don’t cause people to become sickly; rather it is their diet of processed foods high in sodium, sugar and refined carbs which contributes to poor health; cutting out these types of foods will almost certainly improve one’s wellbeing – not the seed oils themselves that cause this change either!
Some also claim that the extraction process for these oils utilizes harmful solvents like hexane, which is harmful to both people and the environment. However, these substances are only used briefly during extraction – making up only a tiny percentage of total amounts extracted – with evidence supporting these claims being quite weak and not particularly convincing.
Another popular perception about omega-6-rich oils is that they cause inflammation due to their omega-6 fat content; however, this assertion is unsupported by evidence; several studies have actually demonstrated the opposite trend – increased omega-6 intake has been associated with lower rates of inflammation rather than vice versa.
Notable here is that the anti-seed oil movement seems to gain significant traction among certain nutrition-minded communities, including paleo and clean eating movements, with overlap occurring with vaccine-skeptical circles as well. Unfortunately, however, this makes it hard to tell whether anti-seed oil opinions are founded in valid research or mere conspiracy theories; but remember not all claims on social media or podcasts can be taken at face value; when making diet-related decisions it is always wisest to consult scientific literature.
