In the past, people generally only used lard and rapeseed oil as edible oil, and even in some areas, only butter. Now, the constant enrichment of edible materials also promotes the increase of edible oil varieties on the table. Then, what nutritional value does our daily edible oil have?
Soybean oil: nutritionally balanced, affordable, is the world’s largest output oil.The monounsaturated fatty acid was 18%-28%.Polyunsaturated fatty acids were 63%, of which linoleic acid was 55% and linolenic acid was 8%.It can reduce serum cholesterol and prevent cardiovascular disease.But soybean salad oil is not resistant to high temperature.
Blending oil: it is a kind of cooking oil made from two or more refined oils in proportion.The cost of blending oil is generally relatively low, and many times the ratio is not clear, do not know the number of beneficial ingredients, easy to mislead consumers.
Peanut oil: peanut oil contains 35%-67% monounsaturated fatty acid and 13%-43% polyunsaturated fatty acid.Moreover, the fatty acid composition of peanut oil is better and easy to be digested and absorbed by human body.Peanuts are easily contaminated with aflatoxin. The toxins produced by aflatoxin are highly carcinogenic. Therefore, it is unsafe to extract crude peanut oil.
Corn oil: peanut oil contains 50-60% polyunsaturated fatty acids and 25%-30% monounsaturated fatty acids. It can strengthen the function of human muscle, heart and blood vessel system and improve the body’s resistance ability.Corn oil has strong thermal stability and can be used for frying and frying.
Lard: high saturated fatty acids, high blood lipids, fatty liver, arteriosclerosis, obesity and so on.But lard is important because its cholesterol is used by the body to make steroid hormones, adrenocortical hormones, sex hormones, and the synthesis of vitamin D itself.Lard – lipoprotein prolongs life, which is lacking in vegetable oils.
Hemp oil: hemp seed oil contains 76% of the highest average monounsaturated fatty acids and 92% of the polyunsaturated fatty acids in all oils, and contains a large number of trace elements such as lecithin, vitamin E, vitamin B, manganese heart selenium and so on.Compared with the fatty acids in the main edible soybean oil, corn oil and peanut oil in China, yishutang flax oil has the same linoleic acid content, while the linolenic acid is obviously higher.Dillinolenic acid has strong effects such as strengthening intelligence, protecting eyesight, lowering blood pressure, lowering cholesterol, delaying senility, anti-allergy and inhibiting the occurrence and metastasis of cancer.
