Because modern food is too industrialized and refined, it is inevitable that some coarse grains and high-content nutrients will be lacking after being ingested into the human body. So we need to make up for it with these things.
In my opinion, it depends on your family environment. If you are not rich, you will always eat some coarse grains in your daily diet. This oil doesn't make much sense. It's similar to corn oil and peanut oil. If you have money at home, it would be better to eat less coarse grains.

With the continuous improvement of living standards, people's nutritional requirements for diet are also constantly improving. According to the Dietary Guide for China Residents, China Residents' Balanced Diet Pagoda puts forward that the oil intake of each person should be controlled at 25g as a nutritional reference, so it is particularly important to choose which edible oil. In this issue, let's walk into the familiar rice bran oil.
According to nutrition, n-6 series linoleic acid and n-3 series linolenic acid are two essential fatty acids for human body. They are all polyunsaturated fatty acids, among which linoleic acid is the most important, which can replace and save linolenic acid to some extent. The oil content in rice bran is 14% ~ 24%, which belongs to functional oil and is a high-quality vegetable oil. The fat in rice bran is mainly composed of palmitic acid (about 17%), oleic acid (about 40%) and linoleic acid (about 34%). In addition, it also contains linolenic acid (about 65438 0%), and their total content accounts for about 92% of the total fatty acids. The nutritional value of oil depends largely on its fatty acid composition and proportion. Monounsaturated fatty acids and polyunsaturated fatty acids in oil can reduce the content of low-density lipoprotein in blood, which is the chief culprit of atherosclerosis and coronary heart disease. The linoleic acid content in rice bran oil is 38%, and the oleic acid content is 42%, and the ratio is 1∶ 1. 1, which is in line with the best ratio of oleic acid and linoleic acid recommended by the international health organization.
The content of unsaturated fatty acids in rice bran oil is over 80%, and the content of essential fatty acids is 35.7%, which can supplement the deficiency of essential fatty acids in human body. Rice bran oil, as the main raw material of high-grade blended oil, health oil and other high-grade oils, has a good curative effect on human cardiovascular diseases. At the same time, rice bran oil is rich in linoleic acid, and normal people can maintain physiological metabolism by ingesting 6g linoleic acid every day. Linoleic acid combines with cholesterol, which is converted into cholic acid and steroids, thus preventing cholesterol from depositing on the blood vessel wall, reducing blood lipid and softening blood vessels. Phospholipids are essential brain-nourishing substances for the normal operation of human nervous system. The glycolipid contained in it has the functions of lowering blood sugar, lowering blood fat and resisting tumor. The total content of unsaponifiable lipids in rice bran oil is 4.2%, especially the content of γ-oryzanol ranks first in all kinds of edible oils, which has important physiological functions, can prevent the deposition of cholesterol, reduce the contents of cholesterol and triglycerides in plasma, especially reduce the ratio of low-density lipoprotein to high-density lipoprotein (its high value indicates that it is easy to get heart disease), thus playing a role in preventing and treating cardiovascular and cerebrovascular diseases.
Rice bran fiber in rice bran oil is a kind of grain fiber with high biological value. In recent 10 years, dietary fiber in food has attracted great attention of nutritionists all over the world. It can prevent and control some diet-related diseases. Rice bran is rich in dietary fiber, especially dietary fiber containing soluble and insoluble fiber. Insoluble dietary fiber can reduce the transportation time of meals in the body, while soluble dietary fiber can reduce serum cholesterol and affect the structural characteristics, gelling characteristics, thickening characteristics and emulsifying characteristics of foods. Moreover, rice bran is rich in other nutrients, which can be used as a source of functional cellulose and as a nutritional source in traditional foods without affecting the original flavor and tissue structure of foods.
Rice bran cellulose contains 74 kinds of antioxidants, which can scavenge active oxygen free radicals in the body. It has a wide range of physiological functions and plays an important role in preventing and improving cardiovascular diseases caused by coronary atherosclerosis. It can inhibit and delay the absorption of cholesterol and triglycerides in lymph, and has stronger adsorption capacity than wheat bran cellulose. It also plays an important role in adsorbing harmful pesticides in human body and preventing liver cancer and colorectal cancer.
