Rapeseed oil and soybean oil are healthy. Rapeseed oil contains a high proportion of monounsaturated fatty acids, especially oleic acid, which can exceed 80% or even exceed olive oil. Oleic acid is a healthy fatty acid, which can reduce the level of bad cholesterol (LDL-C) and improve the level of good cholesterol (HDL-C), and help to prevent cardiovascular diseases. In addition, rapeseed oil also contains a certain amount of phytosterols, which helps to reduce the absorption of cholesterol. Soybean oil is mainly composed of polyunsaturated fatty acids, especially linoleic acid, with a content of 50% ~ 60% and α -linolenic acid content of 5% ~ 9%. Both fatty acids are good for health. Considering comprehensively, soybean oil and rapeseed oil are both nutritious edible oils, and each has its own unique health care function. Rapeseed oil, also known as rapeseed oil and coriander oil, is an edible oil squeezed from rapeseed and one of the main edible oils in China. It is mainly produced in the Yangtze River basin, southwest and northwest regions, and its output ranks first in the world. After years of efforts, China has successfully transformed the traditional inferior high erucic rapeseed oil into low erucic rapeseed oil with excellent nutritional quality.
