2. Oleic Acid
Oleic acid is the most important monounsaturated fatty acid, which is not common or low in daily oil or other foods. Compared with linoleic acid and linolenic acid, the common polyunsaturated fatty acids in daily oil or food, oleic acid has better health benefits: oleic acid in pistachios can not only reduce blood total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C, which belongs to "bad" cholesterol and is the primary pathogenic factor of atherosclerosis), but also increase high-density lipoprotein cholesterol (HDL-C belongs to "good" cholesterol, which helps to prevent the occurrence and development of atherosclerosis), so it is considered to be the fatty acid most beneficial to the health of cardiovascular and cerebrovascular system.
