Efficacy: lowering blood pressure, lowering blood fat
1. Corn oil is golden, transparent and fragrant. It is a kind of grain oil with extremely high nutritional value. Especially suitable for fast cooking and frying food. The freezing point of corn oil is -10℃, and it has good antioxidant stability when frying at high temperature.
2. Corn oil is rich in minerals and a large amount of unsaturated fatty acids. It has a dissolving effect on the accumulation of cholesterol in the blood, so it can lower the cholesterol in the serum and prevent arteriosclerosis. It has a certain auxiliary preventive effect on the prevention and treatment of "three highs" and complications.
3. Corn oil is rich in vitamins A, D, E, which is easy for children to digest and absorb. At the same time, the vitamin D contained in it has a greater effect on promoting the absorption of calcium in the human body, and is extremely beneficial to the development of children's bones.
4. Corn oil is made from corn germ as raw material, and is made into corn germ oil after deacidification, degumming, deodorization, decolorization, dewaxing and other processes. Because the content of linoleic acid is as high as 60%, long-term consumption is harmful to hypertension and obesity. It is beneficial for patients with high blood lipids, diabetes, coronary heart disease, etc.
