Sunflower seed oil is a healthy edible oil, which is famous for its high linoleic acid content. According to Professor Cao Wanxin from Xi 'an Petroleum Research and Design Institute of the State Grain Reserve Bureau, in the 20th century, cardiovascular and cerebrovascular diseases such as coronary heart disease, stroke, cerebral thrombosis, arteriosclerosis, hypertension and other diseases have increased, and long-term consumption of appropriate oil products can greatly improve the above symptoms.
Olive oil Olive oil is rich in monounsaturated fatty acid-oleic acid, as well as vitamin A, vitamin B, vitamin D, vitamin E, vitamin K and antioxidants. Olive oil is considered to be the most suitable oil for human nutrition among the oils found so far.
Among the common edible oils, camellia oil contains the most high-quality fatty acids (up to 90.4%) and the least saturated fatty acids (commonly known as fat), and does not contain indigestible erucic acid. According to the oil theory, most nutrients in camellia oil are easily absorbed and utilized by human tissues. This property is also called "skin-friendliness".
Extended data
In fact, olive oil is similar to peanut oil, and its main nutrient is monounsaturated fatty acid ω-9 (oleic acid), which is not an essential fatty acid for human body. It is ubiquitous in all animal and plant fats, and there is absolutely no need to buy olive oil to supplement it.
Moreover, olive oil is not stored, which is easy to rot and deteriorate, and the domestic olive oil pressing technology is also uneven. In the market, consumers' blind spots of knowledge are often used, and "pomace" and blended oil are used as "super virgin oil", which is expensive and the actual nutritional content is not high.
