菜籽油, or canola oil, is a type of vegetable oil derived from the seeds of the rapeseed plant. It is commonly used in cooking and food preparation due to its light flavor and high smoke point, making it suitable for frying and baking. This oil is also known for its health benefits, as it contains a good balance of omega-3 and omega-6 fatty acids. Additionally, it is low in saturated fat, which can contribute to heart health when used in moderation as part of a balanced diet.
