Seed oils don’t have to be seen as evil. When used at home, however, it should not be consumed excessively in ultra-processed food products that may use industrial seed oils that have been exposed to repeated heating cycles.
These include canola (rapeseed), soybean, corn, sunflower, safflower, and cottonseed oils – often referred to as the “hateful eight.” However, contrary to popular opinion, they’re not all bad!

Are Omega-6 Fatty Acids Bad For You?

Seed oils contain omega-6 fatty acids that have been associated with inflammation. The evidence supporting this link comes from research in rodents, in which linoleic acid turns into arachidonic acid – which forms compounds associated with inflammation – using arachidonic acid as building blocks to produce arachidonic acid and lead to compounds associated with inflammation. Yet human studies have revealed that diets rich in linoleic acid actually reduced inflammation while improving heart health; polyunsaturated fats found in seed oil helped lower cholesterol; together, these factors were instrumental in helping reduce risks for heart attacks and cardiovascular issues significantly.
Even with all their health benefits, most people still believe seed oils to be unhealthy due to misguided beliefs about nutrition and conspiracy theories. People often mistakenly assume seed oils are toxic; this simply isn’t true! Many of the demonization campaigns against seed oils stem from TikTok trends, paleo beliefs or unsubstantiated claims made against them.
As the first step in ridding yourself of industrial seed oils in your pantry, the first step should be a thorough cleanup and discard of any canola, corn, cottonseed, soybean, sunflower, or safflower oils stored there – these oils may have been labeled “healthy,” yet contain chemical residues and trans fats despite labeling claims otherwise.
These chemicals include hexane and synthetic antioxidants. When refining oil from seeds, these substances are used to extract oil; when reused multiple times they generate oxidized byproducts and harmful trans fats that create an unhealthy product.
Avoiding industrial seed oils by cooking with whole food oils such as olive, coconut, and avocado oils sourced directly from nature – such as olive, coconut, and avocado oils from whole-food producers like olive oil, coconut oil,or avocado oil from cold-pressed production methods (these tend to be more costly but could offer health benefits such as vitamin E which many Americans don’t get enough of); doctors such as Dr. Cate Shanahan oppose industrial seed oils due to this reason alone.

Seed oils have long been a controversial subject in nutrition circles, being blamed for everything from heart disease to leaky gut. One factor behind such claims is their omega-6 rich content – getting too much of this fat can contribute to inflammation that leads to various diseases. Some experts advise forgoing seed oils altogether but this recommendation lacks solid clinical proof. It would be more prudent to consume whole food sources of good fats such as whole fruits rather than processed goods for best results.
Oil refineries use high temperatures to refine seed oils, creating potentially dangerous byproducts such as hexane, synthetic antioxidants, trans fats, and peroxides that may become toxic over time. Furthermore, long shelf lives or frequent use in frying may cause the oil to go rancid; to minimize exposure to these toxins, it is recommended that high-quality cooking oils with high smoke points be used when cooking or frying food.
However, most people lack access to high-end cooking oils, and even oil producers don’t always incorporate these premium oils in their products. Restaurants and industrial deep fryers tend to rely on lower cost seed oils which are more susceptible to rancidity.
Some may argue that seed oils are toxic to the gut; this claim is false, though they may lead to inflammation in some people, and it would be prudent to consume less of these seed oils. Avocados and nuts provide healthy sources of fat.
Seed oils often draw controversy for their high concentration of omega-6 fatty acids and their tendency toward oxidation, which can contribute to inflammation and heart disease. As an alternative, vegetable oils high in omega-3 fatty acids, such as flax or hemp oil, are an ideal way to combat inflammation and heart disease; alternatively, fish such as salmon and tuna contain these essential fatty acids that will also help prevent blood clots while improving brain health – providing further benefits including decreased depression risk and enhanced emotional stability.

Seed oils have recently come under scrutiny as potential culprits of cardiovascular disease, cancer, leaky gut, autoimmunity, and brain fog – leading to considerable confusion regarding choosing healthy fats. Unfortunately, due to a lack of reliable nutrition science research studies being used, most misinterpretations are likely inaccurate, but there are a few key facts worth keeping in mind when making fat choices.
Seed oils have long been thought of as potentially unhealthy due to claims that they contain too many omega-6 fatty acids that cause chronic inflammation in the body. According to this argument, omega-6s convert to arachidonic acid in our bodies, which then forms compounds linked to inflammation; however, evidence supporting this claim comes from studies on mice and rats only; human research does not back this up – most experts consider eating plenty of omega-6s an anti-inflammatory diet option.
Many seed oils are refined using chemical extraction processes that lead to rancidity and oxidation, increasing inflammation in the body while damaging gut linings. Furthermore, many of these seed oils lack an optimal balance of omega-3 and omega-6 fatty acids – essential components in mitigating inflammation.
There are ways to reduce seed oils from your diet. The first step should be clearing out your pantry of any canola, corn, cottonseed, soybean, safflower, and sunflower oils that may exist; secondly, remove processed food that often utilizes these unhealthy oils from your diet.
Instead of replacing seed oils with animal fats, try increasing vegetables, whole grains, and lean protein sources such as poultry. When replacing industrial seed oils with non-hydrogenated vegetable oils like olive or coconut oil, you’ll notice improvements in mental performance and energy levels; some even report feeling as if a fog has lifted when they cease eating these highly processed seed oils.

Although some seed oils may be unhealthy, most aren’t. There’s no definitive evidence linking them to inflammation or other health issues, though there has been much misinformation online. Before completely cutting them out of our lives, it is essential to understand their composition: all oils contain various amounts of monounsaturated, polyunsaturated, and saturated fatty acids – with optimal options being high MUFA/PUFA ratios while low SFA content. Unfortunately, most seed oils tend to contain omega-6 fatty acids, which are considered pro-inflammatory fats, rather than healthy counterparts.
One reason that seed oils should be avoided is due to linoleic acid being converted in the body into arachidonic acid, which has been linked with chronic inflammation and disease. Another possible downside of seed oils includes their high oxidation rate which produces free radicals which may contribute to diseases like cancer.
Seed oils are generally genetically modified, which has caused concern from both health and environmental activists who believe GMO crops to be detrimental to both people’s health and the environment. Furthermore, many are exposed to herbicides like glyphosate which has been linked to adverse health conditions.
Some individuals who refrain from using seed oils claim they feel better and lose weight, though this could also be related to eating less processed food in general – some of which is high in calories, sodium, and sugar, contributing to poor health and well-being.
Limit your intake of industrial seed oils in favor of natural, healthier alternatives like olive, coconut or avocado oils. Noting that heat degrades unsaturated fats over time, cold-pressed or expeller-pressed varieties offer less processing.
