I want to say that the term “vegetable” is not very specific. Vegetable oil is a triglyceride extract that comes from plants and is defined as plant-based oils that do not solidify. Vegetable oil is chemically extracted from the seeds. While soybean oil, corn oil, canola oil, sunflower oil, and grapeseed oil are all technically "vegetable oil," in general when people mention vegetable oil they're referring to the oil found at the supermarket that is simply labeled "vegetable oil." . For many decades, vegetable oil has been labeled as a heart-healthy oil, leading consumers to believe that it is good for you. Vegetable oil is a polyunsaturated fat, which has led to the belief that it is heart-healthy, but it is also considered one of the most harmful fats available to consumers. Vegetable oils contain high levels of omega-6 fatty acids, which can be harmful to your health if consumed in excessive quantities.
