What We Recommend Instead

Doritos have a long list of problems beyond seed oils: corn (grain), artificial colors, natural and artificial flavors, citric acid, and tomato powder (nightshade). Siete Nacho Chips use avocado oil but check the full ingredient list for other issues. Better yet, make nachos at home with Siete grain-free chips or pork rinds topped with real cheese.

Clean swaps:

  • Siete Foods Nacho Tortilla Chips (verify full ingredients)
  • Pork rinds with real cheese melted on top
  • Make your own cheese crisps in the oven

What Are Seed Oils?

Seed oils are vegetable oils extracted from seeds using chemical solvents, high heat, and deodorization. The most common ones are soybean oil, canola oil, corn oil, sunflower oil, safflower oil, and cottonseed oil.

They’re in most processed foods and restaurant kitchens because they’re cheap to produce at scale. Before the 1950s, Americans cooked with butter, tallow, and olive oil. Seed oils replaced all of them.

Why Do People Avoid Seed Oils?

Seed oils are high in omega-6 fatty acids. The typical American diet already has far more omega-6 than omega-3, and seed oils make that imbalance worse. Excess omega-6 is linked to chronic inflammation.

People who cut seed oils often notice differences in their skin, digestion, and joint pain. The easiest swap is cooking with olive oil, butter, coconut oil, avocado oil, or beef tallow instead.

Watch Out for These Label Tricks

Seed oils are just the start. When reading ingredient labels, also watch for:

  • “Natural flavors” – a catch-all term that can hide hundreds of chemical compounds. The FDA allows manufacturers to list almost anything under this label without disclosure. If a product needs “natural flavors” to taste good, the real ingredients probably aren’t doing much.
  • “Vegetable oil” – almost always means soybean oil. The word “vegetable” makes it sound healthy, but these oils come from seeds, not vegetables.
  • TBHQ – a synthetic preservative added to seed oils to extend shelf life. Found in Crisco, Pop-Tarts, Maruchan Ramen, and many fryer oils.
  • “And/or” oil blends – when a label says “canola and/or soybean and/or corn oil,” the manufacturer uses whichever seed oil is cheapest that week.

The Bottom Line

Swap Doritos Nacho Cheese for a whole-food alternative or a verified clean brand. The fewer ingredients on the label, the better. When in doubt, make it yourself with ingredients you can pronounce.
