Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of edible plants. Like animal fats, vegetable fats are mixtures of triglycerides.[1] Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of plants. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature.[2][3] Vegetable oils are usually edible.
The health effects of vegetable oil consumption have been the subject of numerous studies. A systematic review in 2015 found that consumption of virgin olive oil significantly reduced cardiovascular disease.[4]
