The Hidden Dangers of Soybean Oil

1 Comment

If you read the ingredients labels, you’ll have noticed soybean oil is hiding everywhere. Sometimes, you might even see it in a “partially hydrogenated” form, or listed as “may contain canola oil and/ or soybean oil” – as if it’s of no importance what you’re actually consuming. I’ve written before about the problem with soy, but soybean oil is another level.

Soybean oil is high in linoleic acid, as the fatty acid break-down of soybean oil is highly skewed towards PUFA’s (poly-unsaturated fatty acids) – not a healthy ratio and unstable at high heats. On top of this it is commonly genetically modified and highly processed. In other words to be avoided.

The problem is soybean oil is everywhere – and for some reason I’ve noticed it in far more foods in Australia that I did living in the UK. For example, the exact same product, Heinz Salad Cream contains Soybean oil in Australia – and not in the UK version:

Australian Heinz Salad Cream Ingredients:

Soya Bean Oil [Protected with Antioxidant (319)], White Vinegar, Sugar, Egg Yolk, Salt, Mustard, Food Acid (270), Stabiliser (412), Colours (171, 101), Herb Extract.

UK Heinz Salad Cream Ingredients:

Spirit Vinegar, Rapeseed Oil (25%), Water, Sugar, Mustard, Pasteurised Egg Yolks (3%), Modified Cornflour, Salt, Stabilisers – Guar Gum and Xanthan Gum, Colour – Riboflavin.

OK so neither have good ingredients, but it’s interesting how they are so different between the two countries. So different that they’re a completely different product. My salad cream tip? Avoid Heinz and make your own easy paleo mayonnaise.

Where else is Soybean oil hiding?

I’ve also seen it in:

  • Vinaigrettes/ salad dressings
  • Mayonnaise
  • Sauces
  • Hummus
  • Crackers

Some brands such as Paul Newman’s seem to use Soybean oil across almost all of their products.
If you’re committed to a Paleo lifestyle, learning how to spot harmful ingredients is an essential part of protecting your health. Soybean oil in particular is an ingredient to keep an eye out for, as it can be surprisingly sneaky in its appearances.

The rise of soybean oil in Australian products

Soybean oil has become the oil of choice for many manufacturers in Australia, thanks to its low cost and long shelf life. However, unlike natural fats from animals or fruits, soybean oil undergoes extensive processing. It’s often extracted using chemical solvents such as hexane, then refined, bleached, and deodorised — none of which are steps you’d consider remotely natural.

Even worse, much of the soybean oil used in food products is derived from genetically modified soybeans. In Australia, GM labelling is not required if the altered genetic material is no longer detectable in the final product — which means oils are often unlabelled despite their GM origin.

Health impacts of excess linoleic acid

The high concentration of linoleic acid (an omega-6 fatty acid) in soybean oil may cause imbalances in the body. While omega-6 is essential in small amounts, modern diets tend to be disproportionately rich in it, especially when consuming processed foods. This imbalance can contribute to inflammation, oxidative stress, and even chronic conditions like obesity and metabolic syndrome.

In traditional Paleo eating, we aim to mimic the ancestral ratio of omega-3 to omega-6, which is estimated to be close to 1:1. Modern Western diets, however, often have ratios of 20:1 or more — largely due to industrial seed oils like soybean oil.

Misleading labelling and deceptive marketing

One of the most frustrating aspects of avoiding soybean oil is how often it is disguised on labels. You’ll see terms like “vegetable oil,” “blended oils,” or even “natural oil blend,” all of which could mean soybean oil. Sometimes it’s listed as “may contain canola and/or soybean oil,” offering no clarity on what’s actually in the product.

Manufacturers are allowed to get away with these vague descriptions because the law permits grouped labelling for similar ingredients. This might make life easier for the manufacturer, but it leaves consumers completely in the dark.

Homemade alternatives for Paleo peace of mind

One of the best things you can do is take control of your ingredients and make your own staples. Not only do you avoid hidden seed oils, but you also cut out other nasties like preservatives, gums, and thickeners.

Here are a few easy swaps:

  • Mayonnaise: Use free-range eggs, olive oil or macadamia oil, lemon juice, and mustard powder. You can make a fresh batch in under 5 minutes with a stick blender.
  • Salad dressing: Combine extra virgin olive oil with apple cider vinegar, a touch of mustard, herbs, and garlic for a zesty dressing that’s free from seed oils.
  • Hummus-style dip: Try using zucchini or cauliflower in place of chickpeas, and blend with tahini, garlic, olive oil, and lemon juice.

Fast food and takeaway traps

Eating out or grabbing takeaway is often a minefield when it comes to hidden seed oils. From salad dressings to grilled meats and even scrambled eggs, soybean oil is frequently used behind the scenes.

When dining out, don’t be afraid to ask questions:

  • What oil is used for cooking or dressings?
  • Can you have your food prepared in butter, olive oil, or without added fats?

The more people ask, the more awareness spreads — and restaurants are more likely to offer alternatives when they realise customers care.

Is organic any safer?

Many people assume that organic automatically means better. While this is true in many respects, organic soybean oil is still soybean oil. It’s still rich in omega-6, and it’s still processed. The only difference is that the soybeans were not sprayed with synthetic pesticides or grown from GM seeds.

For optimal health, even organic seed oils should be avoided on a Paleo diet.

Other names soybean oil may appear under

It’s worth noting that soybean oil may appear under different aliases depending on the product and manufacturer. Keep your eyes peeled for these alternatives:

  • Vegetable oil (unless otherwise specified)
  • Lecithin (typically used as an emulsifier)
  • Hydrogenated or partially hydrogenated soybean oil
  • Glycine max oil (the Latin name for soybean)

Reading labels carefully and understanding ingredient aliases is one of the most powerful tools you have when shopping.

The bottom line: empower your food choices

Avoiding soybean oil isn’t about perfection — it’s about awareness and making informed choices. When you take the time to read ingredient labels, understand the implications of different oils, and make your own staples at home, you reclaim control over your health and wellbeing.

Every time you choose a better alternative, you cast a vote for a different kind of food industry — one that values real ingredients, transparency, and nourishment.

So the moral of the story is – check the ingredients carefully – and if you can’t find a good version – make your own!

Coconut Oil Spray – What’s The Point?

38 Comments

Initially I was really impressed when I saw Coconut Oil Spray for the first time in Coles, my local grocery store.

But on reflection, Coconut Oil spray seems to be a bit of an oxymoron, don’t you think?

Why Spray Cans?

Spray cans of cooking oil became popular to enable the low-fat brigade to cook in as little oil as possible. The spray tin enables you to coat the bottom of the pan, using far less oil than you’d use if you poured it in. But we've moved on from low-fat, haven’t we? Chances are, given that you’re reading this blog, you’re careful to incorporate decent amounts of fat in your diet. Coconut oil is probably the most popular cooking oil amongst those who follow a Paleo diet. Most of my Paleo friends will use generous amounts of coconut oil in their cooking – and then pour the oil from the pan onto their plate when they've finished. You can’t so this with a spray can of coconut oil!

Added Ingredients?

The ingredients also include butane and propane which are obviously required to enable to spray mechanism to work – but I wonder if this has any impact on the oil – and whether there is any residue in the oil when it makes it onto your plate? Another reason I’d prefer to spoon my pure coconut oil straight into the pan, and not take the chance that any of the propellants come into contact with my food. The cans are also highly flammable, another plus for the humble jar of coconut oil!

Who Buys It?

I find it odd that this particular store only stocks the spray and not the oil in normal jar form (my other local supermarket, Woolworths, stocks jars of coconut oil, but not the spray, which is far more useful). Given the choice, I'm sure almost everyone would opt for a jar of coconut oil, rather than the spray?

I can’t really see who the coconut oil spray is aimed at. Compared to the nasty seed oil sprays, it’s far higher in fat (this is a good thing); surely the conventional wisdom junkies would steer clear? And of course those of us in the know about coconut oil would find the small delivery of coconut oil frustrating? So who is it for? Answers in the comments, if you can offer some suggestions…

I can see that the can is convenient – but a jar of coconut oil and a spoon is hardly inconvenient?

Would you use Coconut Oil in spray form? I’d also be interested to read your comments (below) as to whether coconut spray is widely available where you live too?

Margarine or Butter? Seriously?

14 Comments

I couldn't help myself.  I read through October's Issue of “Good Health” magazine today.  Our ideas on what constitutes good health couldn't be much further apart.

I thought conventional wisdom was starting to come round to realising that natural, animal fat maybe isn't so bad after all.  Clearly not.

So, let's compare the ingredients: –

Butter

  • Cream

Margarine (this example is Flora)

  • Water
  • vegetable oils (including sunflower oil) (so other vegetable oils are also in the mix, with a high omega 6 ratio)
  • plant sterol esters (12.5%) (this is an additive that reduces cholesterol, but interferes with absorption of fat soluble vitamins & hormones)
  • modified tapioca starch, salt (1.0%) (this is a chemically altered thickener)
  • buttermilk
  • Emulsifiers: Mono- and diglycerides of fatty acids, sunflower lecithin
  • Preservative: Potassium sorbate, citric acid, vitamin E, flavouring (often synthetic chemicals), vitamin B6, folic acid
  • Colour: Beta carotene, Vitamins A, D and B12

So, this article specifically mentions trans fats.  Well, as Julianne Taylor clearly explains, “trans fat free” margarine doesn't sound too great either.  And as for the trans fat in butter – natural trans fats are created in the stomachs of ruminants (like cows) – and have a completely different fatty acid profile to trans fats found in artificial foods.  A lot of evidence suggests that these natural trans fats may actually be beneficial.

The Real Food Argument: Why Butter Still Wins

After comparing the minimalist ingredients of butter with the lengthy, chemical-laden list in margarine, the choice becomes glaringly obvious. Butter is a real, whole food. Margarine, on the other hand, is a synthetic product engineered to mimic something natural — and not very successfully at that.

What’s often overlooked in mainstream advice is that real food doesn’t need a health claim. Butter doesn’t come with flashy packaging or boast cholesterol-lowering promises — it simply nourishes. And unlike margarine, which is manufactured using industrial seed oils, butter comes from cream that has been churned, traditionally from pastured, grass-fed cows. No solvents, no mystery additives — just a natural fat that has been part of the human diet for thousands of years.

The Trouble With Plant Sterols

One of the most celebrated features of many margarine brands is the inclusion of plant sterol esters. These are promoted as heart-healthy due to their ability to lower LDL cholesterol. But here’s the catch: reducing cholesterol isn’t inherently a good thing. Cholesterol is essential for hormone production, brain function, and cell repair.

By interfering with cholesterol absorption, plant sterols may also impair the absorption of critical fat-soluble vitamins — like A, D, E and K2 — all of which play vital roles in immune function, bone health, and cellular metabolism. So, while margarine may lower a single biomarker, it may compromise broader health in the process.

Omega-6 Overload: The Inflammatory Downside

Most margarine products rely heavily on vegetable oils such as sunflower, soybean, and canola. These oils are high in omega-6 fatty acids — fats that are essential in small amounts but easily overconsumed in the modern diet. When omega-6 intake exceeds omega-3 intake by a wide margin (as is common today), it can tip the body into a chronic inflammatory state.

This imbalance has been associated with conditions such as cardiovascular disease, arthritis, and autoimmune disorders. Butter, especially from grass-fed cows, contains a more balanced fatty acid profile, including a small amount of omega-3 and beneficial saturated fats.

Natural Saturated Fat vs. Artificial Ingredients

Saturated fat continues to be demonised in many mainstream publications, yet the science behind this vilification has always been shaky. The human body is well adapted to using saturated fat as an energy source. It’s stable at high temperatures, which makes it ideal for cooking, and it supports structural integrity in cell membranes.

Meanwhile, margarine's complex cocktail of emulsifiers, thickeners, preservatives and colourings offers nothing that the body recognises as food. Rather than being metabolised and utilised, many of these synthetic additives must be processed and detoxified by the liver — a completely unnecessary burden for the body to carry.

What About the Vitamins Added to Margarine?

It’s true that margarine is often fortified with vitamins — but this is only because the original product has little to no nutritional value. These added nutrients are typically synthetic and may not be well absorbed. Butter, on the other hand, is a rich natural source of vitamins A, D, E, and K2 — especially when produced from grass-fed cows grazing on pasture.

These fat-soluble vitamins work synergistically. For example, vitamin D helps regulate calcium levels, while vitamin K2 ensures calcium is deposited in bones, not arteries. This delicate interaction is part of the brilliance of real food — something a laboratory simply cannot replicate.

Butter and CLA: The Unexpected Bonus

Butter from grass-fed cows is also one of the best dietary sources of conjugated linoleic acid (CLA), a type of fatty acid that has been linked to anti-inflammatory benefits, improved insulin sensitivity, and even fat loss in some studies. CLA is another naturally occurring fat that you won’t find in margarine.

Moreover, butter contains butyrate — a short-chain fatty acid that supports gut health, reduces inflammation in the digestive tract, and plays a role in energy metabolism. Once again, real food provides additional benefits that go far beyond calories and fat percentages.

Cooking With Confidence

If you've been cooking with margarine out of habit or perceived health benefits, it may be time to revisit your pantry. Butter, tallow, ghee, coconut oil and duck fat are all excellent for high-heat cooking and sautéing. They’re not only more stable and resistant to oxidation, but they also add delicious flavour and richness to dishes.

In contrast, cooking with margarine or vegetable oils can create harmful compounds when heated, including aldehydes and other oxidation products — particularly dangerous when reused or exposed to high temperatures.

Don’t Fear Real Food

The shift from butter to margarine was born out of 20th-century nutritional dogma, not long-term evidence. As more studies revisit the impact of dietary fats, it’s becoming clear that traditional fats like butter deserve a place back on our tables.

A Paleo perspective encourages you to ask better questions — not just “Is this food low in fat?” but “Is this food real?” and “How has it been processed?” When you answer those questions honestly, butter emerges as the clear winner.

Making the Switch

If you’re ready to replace margarine with butter in your everyday cooking, here are a few ideas to get started:

  • Spread it on veggies: Melt a knob of butter over steamed broccoli, carrots or zucchini for added richness and nutrients.
  • Bake with it: Use butter in your Paleo baking instead of margarine or vegetable oil for better flavour and stability.
  • Cook eggs in it: Scrambled or fried eggs taste infinitely better when cooked in butter or ghee.
  • Try ghee: If you’re sensitive to dairy proteins, ghee (clarified butter) is a great alternative that retains the benefits without the casein or lactose.

Final Thought: Margarine Has Had Its Day

Margarine was born from an industrial need and kept alive by outdated nutritional advice. Butter, by contrast, is a time-honoured, nutrient-dense fat that has earned its place in the kitchen. So next time you see a health magazine promoting the latest “heart-healthy” spread, take it with a grain of salt — and maybe a pat of grass-fed butter too.

Margarine, seriously?
