Olive oil contains high monounsaturated fatty acids (55~83%), namely oleic acid. In addition to supplying a lot of heat energy needed by human body, it can also adjust the concentration ratio of high density lipoprotein cholesterol and low density lipoprotein cholesterol in human plasma. Linoleic acid and linolenic acid are essential to human body, but human body can't synthesize them by itself, and excessive consumption is also harmful to human body. The proportion of oleic acid, linoleic acid and flax oleic acid contained in olive oil is just the proportion needed by human body, similar to breast milk, which is not found in other vegetable oils; At the same time, olive oil is rich in fat-soluble vitamins such as vitamins A, D, E, F, K, carotene and antioxidants, which are easily digested and absorbed by the human body.
