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

While Heinz Ketchup skips seed oils, it still contains ingredients we recommend avoiding. Read the full label and compare it against a complete food list before assuming any packaged product is clean.
