Sunflower oil can reduce serum cholesterol levels, reduce triglyceride levels, have the effect of lowering blood pressure.

Sunflower oil in the composition of fatty acids due to the impact of climatic conditions, cold regions produce sunflower oil containing oleic acid 15 or so, linoleic acid 70 or so; warm regions produce sunflower oil containing oleic acid 65 or so, linoleic acid 20 or so. The human digestibility of sunflower oil 96.5, it is rich in linoleic acid, there is a significant reduction in cholesterol, preventing vascular sclerosis and the prevention of coronary heart disease. In addition, sunflower oil in the most physiologically active a tocopherol content is higher than the general vegetable oil. And the ratio of linoleic acid content and vitamin E content is more balanced, which is easy for human body to absorb and utilize. Therefore, sunflower oil is an excellent edible oil with high nutritional value and beneficial to human health.

Nutritional value of canola oil

The oleic acid content of unsaturated fatty acids in high-quality canola oil is second only to that of olive oil, with an average content of about 61. In addition, canola oil contains beneficial oleic acid and linoleic acid content of all kinds of vegetable oils.

As the raw material for oil extraction is the seed of plants, it usually contains certain seed phospholipids, which are very important for the development of blood vessels, nerves and brain.
