"Seed oils" is a broad term, and it's easy to get lost in the noise. So let's get clear: the controversy centers around a handful of highly refined oils commonly found in processed foods—soybean oil, canola oil, sunflower oil, safflower oil, corn oil, and grapeseed oil.
Seed oils are everywhere, in: sauces and dressings, hummus, cheese and crackers, granola and cereal, cookies, chocolate, muffins, bread, coffee creamers, infant formula, protein bars and powders, and more …
These oils are high in omega-6 fatty acids, particularly linoleic acid, which in its natural form is essential for health. Like omega-3s, omega-6s are a type of polyunsaturated fatty acid (PUFA), often referred to as "good fats" because they support brain function, immune health, and growth. But here's the key: while both are essential, their effects on the body are very different—omega-3s are anti-inflammatory, while omega-6s can be pro-inflammatory when consumed in excess.
⚖️It's About Balance, Not Elimination
Our ancestors consumed omega-6 and omega-3 in a balanced ratio—roughly 1:1 to 4:1. Today, that ratio is wildly out of balance—closer to 15:1 or even 20:1—due largely to the explosion of refined seed oils in the modern diet. Meanwhile, omega-3-rich foods like fatty fish, chia seeds, flaxseeds, and walnuts are often lacking.
This imbalance creates a chronic state of low-grade inflammation, which is now widely recognized as a driving force behind many modern diseases, including obesity, type 2 diabetes, heart disease, autoimmune disorders, and some cancers.
🔥The Real Problem: How These Oils Are Made
Refined seed oils don't just contain too much omega-6—they're also ultra-processed. To extract them from seeds, manufacturers use high heat, chemical solvents like hexane, and deodorization to improve shelf life and appearance. While omega-6 fats remain in the final product, they've been chemically altered and oxidized in the process.
This damage leads to the creation of oxidized lipids, aldehydes, and even trans fats—toxic compounds linked to inflammation and cellular damage.
So while omega-6 in its natural, whole-food form can be beneficial, the industrial version found in seed oils is a different story. It's this damaged form of omega-6 that's raising red flags in the health world.
🧂"Everything in Moderation"—Easier Said Than Done
Many people say, "Just have seed oils in moderation." But moderation is hard to define when these oils are hidden in so many everyday foods—even in diets that appear "clean." They sneak into dips, sauces, crackers, chips, nut butters, healthy looking processed food and more.
Without awareness, what feels like moderation can quickly become overconsumption.
✅Awareness is Power
This is why tracking your seed oil intake matters. It's not about fear or restriction—it's about knowing where these oils are hiding, so you can make better choices and restore balance.
Refined seed oils aren't going away anytime soon—but being informed is better than being inflamed.
