Edible oil is used in the process of making food, can not play a role in the treatment of coronary heart disease, so the argument that what oil is best for coronary heart disease patients is not scientific. From a nutritional point of view, it is recommended that patients with coronary heart disease consume vegetable oils containing unsaturated fatty acids, such as canola oil, soybean oil, peanut oil, olive oil, corn oil, etc., should reduce the intake of animal oils containing saturated fatty acids. Vegetable oils are generally high in monounsaturated fatty acids, such as canola oil with 58.8% monounsaturated fatty acids, peanut oil with 40.8% monounsaturated fatty acids, and soybean oil with 24.7% monounsaturated fatty acids, which can be used as monounsaturated fatty acid food sources. It is important to note that vegetable oils are not medicines and cannot be used as a substitute for medicines in the treatment of diseases. Vegetable oils generally contain more fat, and patients with coronary heart disease need to eat a low-fat diet, but also should avoid long-term consumption of large amounts of vegetable oils. If you suffer from coronary heart disease, you should be treated under the guidance of a doctor.
