“Seed oils are bad” has become one of the biggest talking points in wellness social media. But when retailers look beyond simplified online claims, the science — and the practical realities of food manufacturing — become far more nuanced.

Not all oils are the same
Highly refined oils repeatedly exposed to extreme heat and poor handling conditions can degrade over time. However, grouping all seed oils into one category ignores major differences in fatty acid profile, oxidative stability, refinement methods and intended application.
Myth vs reality about seed oils
One of the most common myths is that all seed oils are inherently inflammatory or unhealthy. In reality, oils vary enormously depending on how they are grown, how they are processed, their fatty acid composition and how they are used during cooking.
For example, organic high oleic sunflower oil is specifically selected for a higher proportion of monounsaturated fat. This makes it more stable for higher-heat cooking than conventional sunflower oil and gives it a fatty acid profile closer to oils such as olive or avocado oil than many consumers realise.
The more useful question is not simply whether an oil comes from a seed or a fruit. The better question is whether the oil is appropriate for the food application, how stable it is under heat, and how well it has been sourced, processed and stored.
The best oil for salad dressings is not always the best oil for chip frying
Cold-pressed, virgin or extra virgin oils can be excellent for salad dressings, finishing applications and flavour-led recipes. They often retain more natural aroma, colour and flavour compounds, which can be desirable in the right context.
Commercial potato chip frying is different. Snack manufacturers need oils that can withstand prolonged high heat, resist oxidation, maintain a neutral flavour, support shelf stability and deliver consistent cooking performance over production runs.
This is one reason high oleic sunflower oil is widely used in premium snack manufacturing. A less refined oil is not automatically the best choice for every food application.
Best use guide
| Best Use | Often Suitable Oils | Why It Matters |
|---|---|---|
| Salad dressings & finishing | Extra virgin olive oil, virgin avocado oil | Flavour, aroma and natural compounds are part of the appeal. |
| High-heat frying | High oleic sunflower oil, refined avocado oil | Heat stability, oxidation resistance and consistency are critical. |
| Neutral flavour snacks | High oleic sunflower oil | A neutral profile allows the core product flavour to come through. |
| Premium flavour-led recipes | Extra virgin oils | The oil itself contributes to the flavour experience. |
Organic high oleic sunflower oil vs 100% RBD avocado oil
Avocado oil often carries a strong health halo, but not all avocado oils are minimally processed. A 100% refined, bleached and deodorised avocado oil is still a refined oil. It may be suitable for high-heat cooking, but its avocado source does not automatically make it superior.
Organic high oleic sunflower oil can offer a comparable monounsaturated fat profile, strong heat stability, neutral flavour performance and organic certification. It is also often unfairly grouped into generic “seed oil” discussions, despite being quite different from conventional sunflower oil.
The comparison is not simply “avocado oil good, sunflower oil bad”. A more balanced way to assess oil quality is to consider the type of oil, how it is processed, how it is used and whether it suits the application.
Processing matters
Refining is not automatically a negative process. It can improve neutrality, smoke point, shelf life and cooking performance. However, heavier refining can also reduce natural colour, flavour and some naturally occurring compounds.
RBD oil processing may include steps such as degumming, neutralisation, bleaching filtration and deodorisation. In some oil industries, solvent extraction may also be used, with residues strictly regulated by food standards.
For retailers, the most practical takeaway is that oil discussions should not be reduced to one simple label. Processing method, source quality, storage, freshness and intended use all contribute to the final product.
Retailer takeaway
It is not about “seed oils” versus “non-seed oils”. It is about quality, processing, stability and overall diet.
Choose quality. Choose balance. Choose products that are fit for purpose.
Making sense of ingredient conversations
At Fresh Food Enterprises, we help retailers make informed category decisions backed by science, practicality and consumer insight. For independent retailers, this means moving beyond fear-based ingredient trends and focusing on product quality, transparency, shelf appeal and genuine shopper relevance.
