It's not just seed oils.
It's all of it.
Unnasty is the world's first directory dedicated to restaurants that cook without any industrial food chemicals — seed oils, MSG, artificial colours, trans fats, synthetic preservatives, and more.
The Science
Why this stuff matters
The science is increasingly clear. Here's why millions of people are eliminating industrial food chemicals from their diets.
Industrial processing
Seed oils are extracted using hexane solvents, high-heat refining, bleaching, and deodorising. Artificial additives are synthesised in chemical plants. None of this belongs in food.
Omega-6 overload
Seed oils are extremely high in linoleic acid (omega-6), which competes with omega-3s. Modern diets have a 20:1 omega-6 to omega-3 ratio — far from the ancestral 4:1.
Toxic at cooking temperatures
Polyunsaturated fats in seed oils oxidise rapidly when heated, producing aldehydes linked to inflammation, cardiovascular disease, and cellular damage.
Hidden in everything
Seed oils, MSG, and artificial additives are in 99% of restaurant food — often unlabelled. Finding restaurants that avoid all of them is nearly impossible without a directory like ours.
Gut and metabolic disruption
Emulsifiers like carboxymethylcellulose and polysorbate 80 disrupt the gut microbiome. Artificial sweeteners alter insulin response. These are not inert ingredients.
Regulatory blind spots
Many of these ingredients are banned in the EU, Canada, and Australia but still legal in the US and elsewhere. 'Generally recognised as safe' is not the same as safe.
Zero Tolerance List
Banned from our directory.
All of them.
No restaurant in our directory uses any of these ingredients — in any dish, sauce, dressing, marinade, or cooking process. This is not a partial list. It is a complete ban.
What We Approve
Real fats. Real food. Real health.
Humans have cooked with these fats for thousands of years. Our grandparents used them. Our bodies know what to do with them.
Beef Tallow
Lard
Duck Fat
Grass-fed Butter
Ghee
Extra Virgin Olive Oil
Coconut Oil
Bone Marrow
How It Works
Our verification process
We don't take restaurants at their word. Every listing requires documented proof, a manual review, and a verification call before going live.
Restaurant submits application
The restaurant owner fills out our detailed application form, listing all cooking fats used, confirming no nasty ingredients are used in any dish, and selecting the types of proof they can provide.
Documentation review
Our team reviews all submitted documentation: supplier invoices, ingredient lists, menu documentation, chef statements, or third-party certifications. We check for all banned ingredients — not just seed oils.
Verification call
We schedule a brief 15-minute call with the restaurant owner or head chef to confirm their practices, ask follow-up questions, and explain our ongoing compliance requirements.
Listing approved
Once verified, the restaurant appears in our directory with the Unnasty Verified badge. Their documentation is kept on file for ongoing compliance monitoring.
Ongoing monitoring
We re-verify listings annually and investigate any community reports of non-compliance. Restaurants that start using any banned ingredient are removed immediately.
What We Stand For
Our values
Zero Compromise
We don't allow partial compliance. If a kitchen uses any banned ingredient in any dish, they don't get listed.
Radical Transparency
Every verified restaurant has documented proof on file. We show you exactly what they cook with.
Global Mission
Clean food shouldn't be a luxury. We're building the world's most comprehensive clean-eating directory.
Community Driven
Our community nominates restaurants, reports violations, and helps keep the directory honest.
