Why Restaurants Use Seed Oils

There are three reasons every restaurant defaults to seed oils, and none of them have to do with your health:

CheapA gallon of canola oil costs $8–12. A gallon of avocado oil costs $30+. For a restaurant frying hundreds of pounds of food daily, that difference is enormous.
High smoke pointRefined seed oils can hit 450°F+ without smoking. This makes them practical for deep fryers running all day.
Shelf stableSeed oils don’t go rancid as fast as animal fats. Restaurants can leave them in fryers for days without replacing them.
Industry standardFood distributors like Sysco and US Foods push seed oils as the default. Switching requires effort most chains won’t make.

The average American gets roughly 20% of their daily calories from restaurant food, according to USDA data. And nearly all of those meals are cooked in seed oils. That’s a massive source of linoleic acid (omega-6) that most people don’t even think about.

The good news: some chains have made different choices. Here’s the honest breakdown.

Chick-fil-A Best Option

Frying Oil: 100% Refined Peanut Oil

Peanut oil is a legume oil, not a seed oil. Chick-fil-A has used it since 1967.
Pro tip: Order grilled nuggets or a chicken sandwich with no bun and no sauce. The peanut-oil-fried chicken is the cleanest fast food protein you’ll find. Bring your own Primal Kitchen dipping sauce if you want flavor.

Five Guys Best Option

Frying Oil: 100% Peanut Oil

All frying at Five Guys is done in peanut oil. The peanuts at the counter are a hint.
Pro tip: Five Guys is one of the best fast food options. Get a lettuce-wrapped burger with grilled onions and mushrooms, plus a regular fry. The fries are literally just potatoes and peanut oil — two ingredients.

Sweetgreen Best Option

Cooking Oil: Extra-Virgin Olive Oil

Sweetgreen cooks with olive oil and has publicly committed to avoiding seed oils in their cooking.
Pro tip: Sweetgreen is arguably the cleanest fast-casual chain in America for seed oil avoidance. Build a custom bowl with greens, roasted veggies, protein, and olive oil-based dressing. Check their ingredient list online — they’re transparent about it.

Chipotle Proceed with Caution

Cooking Oil: Rice Bran Oil

Rice bran oil IS technically a seed oil (extracted from the bran of rice). However, some items at Chipotle don’t involve cooking oil at all.
Pro tip: Get a salad bowl with carnitas or barbacoa, black beans, pico, guacamole, cheese, sour cream, and lettuce. Skip the rice, tortilla, and dressing. The carnitas are your best protein option since they’re braised rather than grilled in oil.

Cava Proceed with Caution

Cooking Oil: Canola/Olive Oil Blend (varies by item)

Cava uses a combination of oils. Some items use olive oil, others use canola. It varies by ingredient.
Pro tip: Cava is less transparent than Sweetgreen about their oils. Ask the staff directly what oil each protein is cooked in. Stick to fresh (uncooked) toppings and verified olive oil-based dips when possible.

In-N-Out Burger Proceed with Caution

Frying Oil: Cottonseed Oil Blend

Cottonseed oil IS a seed oil. In-N-Out uses it for frying. However, their menu is simple enough that you can work around it.
Pro tip: Order a Double-Double “protein style” with no spread, add mustard (mustard-grilled if you like). The beef patties are fresh and cooked on a flat grill — they don’t sit in a seed oil fryer. Skip the fries entirely.

Panera Bread Proceed with Caution

Cooking Oil: Varies (canola oil in many items)

Panera uses canola oil and soybean oil across much of their menu, but some items are naturally safer.
Pro tip: Panera is tough. The bread — their whole identity — contains seed oils. Your best bet is a salad with no dressing, or bring your own olive oil-based dressing. Ask for olive oil packets if available.

Shake Shack Proceed with Caution

Frying Oil: Canola/Soybean Oil Blend

Shake Shack fries in seed oil blends. But their burger patties are cooked on a flat-top griddle.
Pro tip: Get a double ShackBurger in a lettuce wrap, no ShackSauce, add grilled onions. The patty is griddle-cooked beef — just skip the bun, fries, and sauces. Bring your own condiment.

McDonald’s Avoid if Possible

Frying Oil: Canola Oil Blend

McDonald’s uses a canola oil blend for all frying. Seed oils are in the buns, sauces, and most menu items.
Pro tip: McDonald’s is one of the hardest places to eat seed oil free. If you’re stuck here, a plain burger patty (no bun, no sauce) and a black coffee is about all you can do. Even the “grilled” chicken has seed oils in its marinade.

Wendy’s Avoid if Possible

Frying Oil: Blend of Vegetable Oils (canola, soybean, corn, cottonseed)

Wendy’s uses a multi-seed-oil blend for all frying and lists seed oils in most menu items.
Pro tip: Wendy’s uses fresh, never-frozen beef — so a plain patty is decent quality. Order a double stack with no bun, no mayo, no sauce. Add fresh veggies. That’s the cleanest option here.

Subway Avoid if Possible

Cooking Oil: Canola Oil (in bread) + Soybean Oil (in sauces)

Every Subway bread contains canola or soybean oil. The sauces are seed oil-heavy. Even the “fresh” image is misleading.
Pro tip: The only viable option at Subway is ordering your sub as a chopped salad with no dressing. Bring your own olive oil-based dressing packet. It’s not glamorous, but it works.

Starbucks Proceed with Caution

Cooking Oil: Varies by Item

Starbucks drinks are generally safe. The food is where seed oils hide.
Pro tip: Starbucks is fine for drinks — stick to coffee, tea, or simple lattes. The moment you touch their food case, you’re in seed oil territory. If you need a snack, grab the fruit or the cheese plate and skip the crackers.

How to Eat Out Seed Oil Free Anywhere

Even at restaurants not on this list, you can minimize seed oil exposure with these strategies:

Ask what oil they fry inThis is the single most important question. If they say “vegetable oil” or can’t tell you, assume seed oils. If they say olive oil, avocado oil, peanut oil, butter, or tallow, you’re in better shape.
Grilled beats fried, alwaysA grilled chicken breast on a flat top has minimal oil contact. A fried chicken sandwich was submerged in it. Choose grilled every time.
Skip the dressingRestaurant dressings are almost universally soybean or canola oil based. Ask for olive oil and vinegar, lemon wedges, or bring your own Primal Kitchen packet.
Bunless is your friendMost restaurant buns contain soybean oil. Order burgers lettuce-wrapped or “no bun” and save yourself the seed oils plus the processed carbs.
Steak houses are generally safeA steak cooked in butter on a hot grill is about as seed oil free as restaurant food gets. Sides like baked potatoes with butter and steamed vegetables are clean too.
Bring your own condimentsKeep a few Primal Kitchen dressing or sauce packets in your bag. Sounds extreme until you realize it’s the difference between a clean meal and a seed oil bath.
Mexican restaurants are often saferMany authentic Mexican restaurants cook with lard or tallow — traditional fats, not seed oils. Ask if they use manteca (lard). Taquerías are often better than chains.
Check online before you goMost chain restaurants publish full ingredient lists and allergen info online. Spend two minutes checking before you order. It’s much easier than interrogating the cashier.
The 80/20 rule: You don’t need to be perfect. Avoiding fried foods, skipping sauces and dressings, and choosing grilled proteins eliminates 80%+ of the seed oils in a restaurant meal. The bun and the fries are where most of it hides.

Frequently Asked Questions

Does Chick-fil-A use seed oils?

Chick-fil-A fries in 100% refined peanut oil, which is not a seed oil. However, some sauces, dressings, and buns contain soybean or canola oil. The fried chicken and grilled items are your safest options — just skip the sauces and bun.

What fast food restaurants don’t use seed oils?

No major chain is completely seed oil free. The best options are Chick-fil-A and Five Guys (peanut oil for frying), Sweetgreen (olive oil for cooking), and Chipotle (some items avoid direct oil contact). You can also order grilled items and skip sauces at most chains.

Is peanut oil a seed oil?

No. Peanuts are legumes, not seeds. Peanut oil has a different fatty acid profile than industrial seed oils — it’s higher in monounsaturated fat and has been used for cooking long before modern seed oil processing. It’s generally considered safe by most seed oil-free advocates.

How do I ask a restaurant what oil they use?

Simply ask: “What oil do you fry in?” or “What oil is used on the grill?” Most employees know or can check. For chains, the information is available online in allergen/ingredient guides. If they say “vegetable oil” or don’t know, assume seed oils.

Can you eat seed oil free at McDonald’s?

It’s very difficult. McDonald’s fries everything in canola oil blend and uses seed oils in buns, sauces, and even some grilled items. Your safest option is a plain burger patty (no bun, no sauce) with a side salad and no dressing. But honestly, there are better options — see the restaurants rated “Best Option” above.
