In vegetable oil, the oleic acid content of olive oil reaches 80%, the oleic acid content of ordinary peanut oil is 40%-67%, the high oleic acid peanut varieties are usually more than 75%, generally around 80%, and some individual varieties are as high as 90%, while the oleic acid content of traditional soybean oil is only about 20%-25%.
“Compared with olive oil, peanut oil with high oleic acid can be fried, cooked and stir-fried, which is more suitable for Chinese eating habits.” Yu Shanlin, former chief scientist of the national peanut industry technology system, told the “Financial National Weekly” reporter that North China has the habit of eating peanut oil for a long time, and the content of resveratrol in peanut roots is about 908 times that of grapes, and the content of resveratrol in red clothes is about 20 times that of grapes, so the nutritional effect of peanuts can soften blood vessels.
High oleic acid has the effect of antioxidant, reducing harmful cholesterol, lowering blood lipids, reducing the risk of cardiovascular and cerebrovascular diseases, and has health care functions. Research results at home and abroad show that it has the following advantages:
(1) Oxidation resistance, prolong shelf life
Oleic acid is a relatively stable substance, high oleic acid edible oil stability is higher than ordinary oil, can extend the shelf life and shelf life of the oil.
(2) Reduce harmful cholesterol, lower blood lipids, is beneficial for cardiovascular and cerebrovascular health
Oleic acid can reduce bad cholesterol in the human body and keep good cholesterol from decreasing, which has the effect of reducing blood lipid levels and preventing cardiovascular disease.
(3) Reduce inflammation, regulate white blood cells, and inhibit the spread of cancer
Studies by the Federal University of UFTM in Brazil and the University of São Paulo in Brazil have shown that oleic acid can reduce inflammation, regulate white blood cell activity, enhance bactericidal effect, inhibit cancer spread and oncogene expression, lower blood pressure and weaken the effects of autoimmune diseases. At the same time, it can prevent the occurrence of autoimmune diseases, metabolic disorders, skin damage and cancer.
4) Prevent memory loss
A study published in the American journal “Neurology” showed that oleic acid can prevent the decline of memory and cognitive function brought about by people’s age, because monounsaturated fatty acids are components of neuronal cells, which can maintain the integrity of neuronal cells
