Vegetable oil is a generic term for refined seed oils, often a blend of soybean, corn, and/or canola oil. While it contains negligible carbohydrates, it is typically classified as high-carb–adjacent in SmartCarbSub due to its common pairing with high-carb foods and heavy processing. It is not ideal for keto or diabetic-focused diets despite being technically carb-free.
