 The Hidden Gut-Destroying Ingredient in Nearly Every Packaged Food

If you’re trying to heal your gut, improve your skin, balance hormones, or just feel better — this one’s for you.

There’s an ingredient lurking in most people’s pantry, hiding in “healthy” products, and silently inflaming your gut lining every single day:

Industrial seed oils

We’re talking about:

• Canola oil

• Soybean oil

• Sunflower oil

• Cottonseed oil

• Vegetable oil

• Rice bran oil

• Rapeseed oil

• Safflower oil

How are industrial seed oils made?

Let’s just say… it’s not a natural process.

Most of these oils come from genetically modified seeds that were never meant to be part of the human diet. Think soybeans, cottonseeds, and corn. These are leftovers from mass agriculture.

Here’s how they’re made:

1. Mechanical extraction – the seeds are heated and crushed using heavy machinery.

2. Chemical solvents – usually hexane, a petroleum-based solvent, is used to extract more oil. (Hexane is toxic and banned in food production in some countries.)

3. Deodorisation – because the oil smells awful, it’s chemically treated to remove odour.

4. Bleaching – to make the oil look more appealing and mask oxidation.

5. Stabilisation – synthetic antioxidants and preservatives are added to stop it from going rancid on shelves.

What you end up with is a heavily refined, highly unstable, ultra-inflammatory oil — and unfortunately, it’s in everything.

Why do they wreak havoc on your gut (and body)?

1. They destroy the omega-6 to omega-3 balance

Industrial seed oils are loaded with omega-6 fatty acids — far more than our bodies were designed to handle. In excess, omega-6s promote the formation of inflammatory compounds like arachidonic acid, which damage tissues, inflame the gut lining, and impair healing.

2. They oxidise rapidly — especially during cooking

These oils are fragile. When heated (even just during processing), they form oxidised fats like:

• Trans fats – linked to heart disease and gut barrier dysfunction

• Lipid peroxides – which damage cell membranes and trigger inflammation

Your gut lining is made up of lipid membranes. These compounds damage them directly.

3. They’re full of additives that disrupt hormones and immunity

Because these oils are unstable, manufacturers load them up with preservatives, synthetic antioxidants (like BHT and TBHQ), and anti-foaming agents, many of which are known endocrine disruptors and immune system suppressors.

4. They feed the wrong bacteria

Chronic inflammation and oxidative stress from these oils can alter your gut microbiome, promoting the growth of opportunistic pathogens, feeding candida, and weakening your overall gut barrier function.

5. They’re reheated and reused — making them even more toxic

In restaurants, cafes, and takeout food, these oils are often reheated multiple times in deep fryers — creating dangerous byproducts like aldehydes and acrylamide. These compounds are highly inflammatory, carcinogenic, and harmful to your digestive and neurological systems.

Where are they hiding?

The scary part? These oils are everywhere.

Even in things that look healthy:

• “Natural” muesli bars

• Roasted nuts

• Gluten-free crackers

• Dried fruit

• Plant-based milks

• Sauces and dressings

• Protein powders and snack balls

• Hummus, dips, and spreads

Always check the label — they often go by names like vegetable oil, canola oil, or sunflower oil. If it doesn’t explicitly say “cold-pressed” or “extra virgin,” assume it’s refined.

What to use instead

Swap these industrial oils for natural, nutrient-rich fats that your body knows how to use and process:

• Extra virgin olive oil

• Cold-pressed avocado oil

• Coconut oil (unrefined)

• Grass-fed butter or ghee

• Tallow, duck fat, or lard from pasture-raised animals

These fats are stable, anti-inflammatory, and actually help rebuild your gut lining and support hormone function.

If you're serious about healing your gut, reducing bloating, clearing up your skin, or balancing your hormones 

It’s not about being perfect, it’s about being aware.

Read your labels. Ask what your food is cooked in.
Choose whole, clean, nourishing fats wherever you can.
