The Seed Oil Argument, and What "Clean Label" Really Means on a Food Jar

Few food topics generate more heat than seed oils. One side treats canola and soybean oil as the single cause of modern ill health. The other points out that the evidence for that is thin and the panic is largely a social media phenomenon. Most people are somewhere in the middle and just want to know what to buy.

Here is a calmer way to think about it.

What the argument is actually about

Seed oils - canola, soybean, sunflower, corn, cottonseed - are high in omega-6 fatty acids, particularly linoleic acid. The concern raised is that modern diets contain far more omega-6 than omega-3 compared with historical patterns, and that industrial refining involves high heat and solvents.

The counter-argument is that large reviews of the actual human evidence have not found that replacing saturated fat with these oils makes health outcomes worse, and that the refining concerns are often overstated.

Honest summary: this is genuinely unsettled, the loudest voices on both sides are more certain than the evidence supports, and nobody should be reorganising their entire diet around a single nutrient ratio.

The more useful question

Here is what we think the seed oil debate is really a proxy for: people have noticed that a lot of what they eat is industrially assembled from ingredients they cannot picture, and they do not like it.

That instinct is reasonable, and it survives regardless of who is right about linoleic acid. Ultra-processed foods tend to be energy dense, easy to overeat and low in fibre - and that is much better established than the seed oil case.

A better label test than counting oils

Instead of scanning for one villain ingredient, try these:

• Can you picture every ingredient? Not "is it natural" - can you actually form a mental image of it. Honey, yes. Sodium stearoyl lactylate, no.
• How many ingredients are there? Not a perfect measure, but a fast one.
• Is the first ingredient the thing you think you are buying? Ingredients are listed by weight. A "honey" product whose first ingredient is corn syrup is a syrup product.
• Does the front of the pack match the back? The front is advertising. The back is regulated.

What "clean label" should mean

The phrase has been thoroughly diluted by marketing. It should mean something simple: the label tells you the truth, in words you can check, without needing to trust anyone.

Our jars are two or three ingredients - raw honey and one herb - because that is a claim you can verify by reading rather than by believing us. That is the only version of clean label that means anything.

What we would actually do

Cook at home more often than not, buy ingredients rather than products where you can, and do not lose sleep over the oil in a restaurant meal. The evidence for that approach is far stronger than the evidence for or against any single oil.
