Seed oils have quietly become the villain of modern wellness. Soybean oil, sunflower oil, canola, corn: everywhere you look, someone is blaming them for inflammation, weight gain, and poor health. Many people are switching back to butter, convinced that seed oils are the root cause.
The truth is less dramatic, and more useful: most of the blame belongs to the company oil keeps, not the oil itself.
What Are Seed Oils?
Seed oils refer to a group of refined vegetable oils extracted from seeds, including:
-
Sunflower oil
-
Soybean oil
-
Canola oil
-
Corn oil
-
Cottonseed oil
-
Safflower oil
-
Grapeseed oil
-
Rice bran oil
Most of these are industrially processed cooking oils. They're extracted using high heat and chemical solvents, then refined, bleached, and deodorised to make them neutral in taste and long-lasting on shelves. They're also the most common fat in packaged and ultra-processed food.
That last part matters. We'll come back to it.
Are Vegetable Oils Unhealthy?
Not in the way they're often portrayed. The idea that seed oils are "toxic" or inherently unhealthy is largely a misunderstanding.
Seed oils are high in unsaturated fats, which some research suggests can help lower LDL cholesterol when used in place of saturated fats like butter.
So the oil itself isn't necessarily the problem. The confusion comes from how, and where, it's used.
Seed Oils and Inflammation: What the Research Says
The main charge against seed oils is that they're high in omega-6 fatty acids, which supposedly cause inflammation. That claim has spread fast, but it rests on a misunderstanding.
Omega-6 and omega-3 are both essential fatty acids. Your body needs them and can't make them on its own. Omega-3s do have stronger anti-inflammatory properties, and somewhere along the way that got twisted into the idea that omega-6s do the opposite:
-
Omega-3 = anti-inflammatory
-
Omega-6 = inflammatory
That's not how the body works, according to much of the current research. Omega-6 fatty acids consumed as part of a normal diet are not consistently linked to inflammation, and can be part of a healthy balance of fats.
Why Do People Feel Better After Avoiding Seed Oils?
Usually because they're not just removing seed oils. They're removing ultra-processed food.
Think about where seed oils show up most:
-
Packaged snacks
-
Fried fast food
-
Ready-to-eat meals
-
Store-bought dressings and sauces
When someone cuts out seed oils, they usually cut out these foods at the same time, and that's where the real shift happens:
-
Less refined sugar
-
Less excess sodium
-
Fewer additives
-
Fewer highly processed ingredients
So yes, people often feel better, but cutting out seed oils usually means cutting out a whole cluster of other things at the same time. That broader shift is doing most of the work.
Cold Pressed Oils vs Seed Oils: A Cooking Oil Health Comparison
Here's the distinction worth making when you're weighing cold pressed oils vs seed oils.
Refined oils (most industrial seed oils) go through high-heat extraction, chemical solvent processing, and bleaching and deodorisation. This makes them shelf-stable, neutral in flavour, and consistent at scale. It also strips away natural antioxidants, polyphenols, and distinct flavour compounds.
Cold pressed oils (unrefined) are extracted mechanically at low temperatures, without chemical solvents. What you get is closer to the seed's natural flavour and its natural nutrient profile. These chemical free cooking oils are less about mass production, and more about preserving what the seed naturally offers.

What's the Healthiest Cooking Oil, and Is There a Single Best Oil for Cooking?
Probably not one single answer. What matters more than any one label is:
-
How the oil is processed
-
What you're eating it with
-
How often you rely on ultra-processed food
If you're cooking at home and choosing oils that are less processed and closer to their natural state, you're already making a better choice than reaching for whatever's cheapest at the back of a packaged-food shelf.
Should You Stop Using Seed Oils?
You don't need to fear seed oils. They aren't ‘destroying your health,’ and much of that idea comes from confusing ingredients with eating patterns.
But not all oils are made the same way, and how an oil is processed, refined, and consumed matters far more than the label ‘seed oil’ itself.
Ultra-processed food deserves far more of the blame here than seed oils do. How any cooking oil, seed-based or otherwise, is made and used matters more than the category it falls into.
FAQs
1. Are seed oils bad for you?
Not inherently. Seed oils get most of their bad reputation from where they show up, in fried and packaged food, rather than from the oil itself. Cooking with them occasionally at home is a different picture from eating them mainly through ultra-processed food.
2. Do omega-6 cooking oils cause inflammation?
This is one of the most debated claims around seed oils, and the science is more nuanced than the popular version suggests. Omega-6 is an essential fat your body needs, and current research doesn't show a consistent link between normal dietary intake and inflammation. If you have a specific health condition, it's worth checking with a nutritionist rather than relying on general claims either way.
3. What's the difference between refined seed oils and cold pressed oils?
Refined seed oils go through high heat, chemical solvents, bleaching, and deodorising to make them shelf-stable and flavour-neutral. Cold pressed oils are extracted mechanically at low temperatures without chemical solvents, which keeps more of the seed's natural flavour and nutrient profile intact.
4. What's the healthiest cooking oil to use?
There isn't one single answer. How the oil is processed, what you're cooking it with, and how often you rely on ultra-processed food all matter more than any one oil's label. Choosing a less processed oil is a reasonable starting point, not a complete health strategy on its own.
5. Should I switch from seed oils to a cold pressed oil like Gramiyaa's?
That depends on what you're looking for. If you'd rather cook with an oil that's closer to its natural state and traceable back to its source, Gramiyaa's single cold pressed, unrefined oils are built for that. They aren't a medical fix for anything seed oils are blamed for, just a different way of processing the same category of ingredient.
