Because its main component is linoleic acid, its nutritional value is particularly high, which can prevent the deposition of human serum cholesterol on the blood vessel wall and prevent atherosclerosis and cardiovascular diseases. In pharmaceutical industry, safflower seed oil can be used to make drugs for preventing and treating cardiovascular diseases, hyperlipidemia, hypertension, hyperglycemia, liver cirrhosis and other diseases. In addition, safflower seed oil also contains a large number of medicinal components such as vitamin E, oryzanol and sterol, so it is known as a new "healthy oil" and "healthy nutritional oil". 1. The linoleic acid content in safflower seed oil is ≥67.8% (the national minimum standard). The content of linoleic acid in safflower seed oil is the highest among known plants, so it is known as the "king of linoleic acid". 2. There are eight basic substances in human life activities, including protein, water, minerals, vitamins, sugar, fat, cellulose and unsaturated fatty acids. There are some unsaturated fatty acids that cannot be synthesized by human beings and must be absorbed from food, which are called essential unsaturated fatty acids. Among the essential unsaturated fatty acids, three kinds of unsaturated fatty acids are very important, namely linoleic acid, linolenic acid and arachidonic acid. 3. As long as the human body is not short of linoleic acid, two other essential unsaturated fatty acids can be synthesized. Therefore, linoleic acid is the most important unsaturated fatty acid in human body and the basic substance of life. 4. The human body cannot synthesize linoleic acid by itself, and it must be taken from the diet. 5. Linoleic acid is a component of cells, especially involved in the synthesis of phosphorus in mitochondria and cell membranes. Linoleic acid deficiency may lead to mitochondrial swelling, changes in cell membrane mechanism and function, and increased membrane permeability and brittleness. 6. Linoleic acid is closely related to lipid metabolism. Cholesterol in the body must be combined with fatty acids to be transported in the body for normal metabolism. After linoleic acid deficiency, cholesterol transfer is blocked and cannot be metabolized normally, which will be deposited in the body and eventually lead to diseases. 7. Linoleic acid is a necessary prerequisite for the synthesis of prostaglandin. Without linoleic acid in the body, the ability of tissue to form prostaglandin will decrease. Linoleic acid can also protect some skin damage caused by X-rays. 8. Safflower seed oil can not only prevent cardiovascular and cerebrovascular diseases, but also treat fatty liver. 9. Another function of linoleic acid is the raw material of cell membrane. The substance that constitutes the cell membrane is unsaturated fatty acid. Linoleic acid can enhance metabolism and cell vitality. 10. safflower seed oil is rich in natural vitamin e, with an average content of about 800mgDL, which is the highest among all plants, so safflower is known as the "crown of vitamin e". Vitamin E in safflower seed oil is a kind of natural vitamin E with natural life activity. Vitamin E is a strong reducing agent and has a strong antioxidant effect. It also has the function of anti-aging and rejuvenates aging cells and tissues.
