Compared with other cooking oil on the world, Australian canola oil saturated fatty acid content is the lowest (8%), unit of unsaturated fatty acid content is higher (61%), slightly lower than olive oil, but also owns 31% of the best proportion of polyunsaturated fatty acids. Fatty acids composition proportion, is the most important index evaluating oil nutritional value, lower oil saturated fatty acid is more healthy. The cholesterol in food is not the main cause of high cholesterol in the blood, but the body USES saturability soften grease into cholesterol and accumulation in the liver and blood, therefore, it is very important to decrease saturated fat intake. All oil contains three kinds of fatty acids: saturated fatty acids, unit of unsaturated fatty acids and polyunsaturated fatty acids. Saturated fatty acid intake increases the cholesterol in the blood; Mono most is not easy to increase the concentration of blood cholesterol, also not easy to be oxidized; Polyunsaturated fatty acids have been shown to reduce the cholesterol in the blood.
