Generic "vegetable oil" (without a named source)
What it is
When a label lists "vegetable oil" without naming the specific source plant, the actual oil could be soybean, canola, sunflower, corn, palm, cottonseed, safflower, or a blend that changes batch-to-batch as commodity prices shift. Soybean oil is the largest single source (~57% of US edible oil supply per USDA) but corn oil, sunflower oil, and canola are also common bases. Specific named oils — "canola oil," "coconut oil," "sunflower oil" — name their source and are not ambiguous. Bare "vegetable oil" is opaque by design.
Relevant concerns
- Soy
Generic vegetable oil is most frequently soybean oil. Users avoiding soy (allergy or inflammation management) often can't tell from the label.
- Corn
Corn oil is also a common base for industrial vegetable oil formulations. Corn-avoiders should treat bare vegetable oil as ambiguous.
- AIP (Autoimmune Protocol)
AIP elimination excludes most industrial vegetable oils regardless of source. Specific permitted oils (coconut, olive, avocado, lard, tallow) are named when used.
