What Oils Are Used in Chips?

The Short Answer

Almost every conventional chip on the grocery store shelf is deep-fried in a blend of refined seed oils. If you look at the back of a bag of Lay's, Ruffles, or Doritos, you will see a confusing ingredient list that says "Vegetable Oil (Canola, Corn, Soybean, and/or Sunflower Oil)."

This "and/or" labeling allows manufacturers to use whatever oil is cheapest that day. Because chips are roughly 35% fat by weight, the quality of this oil is the single biggest factor in whether a chip is a harmless treat or an inflammatory nightmare. Are Chips Bad

Why This Matters

Seed oils are practically unavoidable in the modern food supply. They are massively high in omega-6 fatty acids, which can skew your body's essential fat ratios and drive chronic inflammation.

When these oils are heated to the 350°F+ temperatures required for deep frying, things get exponentially worse. High-heat frying causes seed oils to oxidize and break down. This process creates free radicals and inflammatory compounds that you ingest with every single crunch.

Even "healthier" natural brands fall into this trap. Many organic chips proudly claim to be clean, but rely heavily on refined sunflower or safflower oil. If you are trying to cut down on your total seed oil consumption, you need to know exactly what to look for. Chips No Seed Oils

What's Actually In Chips

The ingredients list on most chip bags reveals a cocktail of cheap, heavily processed fats. Healthiest Chips

• Canola Oil — Extracted using high heat and harsh chemical solvents like hexane. It is cheap, abundant, and neutral in flavor, making it the bedrock of the snack food industry.
• Soybean & Corn Oil — Sourced almost entirely from GMO crops treated with pesticides. These are some of the cheapest and most heavily processed oils available.
• Sunflower & Safflower Oil — Packed with omega-6 fatty acids. These are often found in "natural" or organic chips to avoid GMOs, but they are still highly refined and prone to oxidation when heated.
• "Vegetable Oil" — A deceptive umbrella term. If a label just says "vegetable oil," it is almost guaranteed to be a cheap, highly refined blend of soybean and corn oil.

What to Look For

Green Flags:

• Avocado Oil — Loaded with heart-healthy monounsaturated fats. It has a naturally high smoke point, making it perfectly stable for commercial frying without breaking down. Is Siete Chips Clean
• Coconut Oil — Rich in stable saturated fats. It holds up beautifully to high heat without oxidizing into harmful compounds. Is Jacksons Chips Clean
• Beef Tallow — The traditional way chips were made before the 1990s. Grass-fed tallow is nutrient-dense, highly stable, and gives chips an unmatched, savory flavor.

Red Flags:

• The "And/Or" Blend — Proof that the brand prioritizes profit over quality. "Canola and/or sunflower oil" means you have no idea what you are actually eating.
• Expeller-Pressed Seed Oils — A clever marketing trick. While expeller-pressed means no chemical solvents were used, it is still a refined seed oil prone to oxidative damage under high heat.

The Best Options

You don't have to give up chips entirely to avoid seed oils. Several brands have stepped up to provide snacks fried exclusively in stable, premium fats. Chips No Seed Oils

The Bottom Line

1. Ditch the "and/or" blends. If the label lists multiple seed oils separated by "and/or," put the bag back on the shelf.

2. Look for avocado, coconut, or tallow. These are the only three fats that remain highly stable when deep-fried at commercial chip-making temperatures.

3. Check your "healthy" chips. Don't assume a chip is clean just because it is organic or sold at a premium health food store—most still use refined sunflower oil. Are Veggie Chips Healthy

FAQ

Are baked chips healthier than fried chips?

Not necessarily. While baked chips generally have less total fat, they almost always still contain refined seed oils for texture and flavor. Plus, they often rely on more refined starches and sugars to make up for the lack of fat. Are Baked Chips Healthier

What's wrong with sunflower oil in chips?

Sunflower oil is extremely high in omega-6 fatty acids, which most Americans already drastically overconsume. Even though it is often non-GMO and found in premium snacks, high-heat frying still causes it to oxidize and create inflammatory compounds.

Why do chip companies use seed oils?

It comes down to cost and shelf life. Seed oils are incredibly cheap to produce and have a neutral flavor that doesn't overpower the potato or corn. Traditional, stable fats like tallow or avocado oil are significantly more expensive to source.
