On land, there is nothing like linseed oil to nourish the brain; Linseed oil can be called "student food" or "intellectual food". Its cell matrix contains lignans, which is 100-800 times higher than other commonly used cereals and beans. Flaxseed also contains 18 amino acids, three vitamins (A, E, B 1) and eight trace elements necessary for human body. Linseed oil is mainly composed of α -linolenic acid, the content of which is as high as 50-60%, which is 2.5 times that of deep-sea fish oil (20-26%). Once the human body lacks α -linolenic acid for a long time, it will lead to the functional decline of brain organs and visual organs and the occurrence of Alzheimer's disease, and will lead to the increase of the incidence of modern diseases such as hypertension, hypertension and cancer.
Efficacy of linseed oil:
1, has anti-inflammatory, antithrombotic, antiarrhythmic, hypolipidemic, hypoglycemic, carbuncle-lowering, cholesterol-lowering, blood cleaning, blood vessel cleaning and vasodilation effects, and can prevent diabetes, hypertension, apoplexy and myocardial infarction.
2. It has the functions of supplementing brain cell nutrition, promoting intellectual development, improving memory, preventing brain atrophy and Alzheimer's disease, improving anti-stress ability and reducing depression and insomnia.
3. It has anticancer, antifungal and antiallergic effects.
4. It has the functions of strengthening the body, enhancing skin softness, luster and elasticity, improving immunity, reducing oil deposition and losing weight.
5. It can improve renal function, relieve asthma, increase intestinal peristalsis, prevent constipation, prevent arthritis and improve premenstrual syndrome in women.
Organic flaxseed oil tastes pure. In order to obtain the best nutrition and taste, it can be drunk directly or eaten with other foods. Please avoid high temperature heating.
Please put it in the refrigerator after opening the bottle to reduce the chance of flaxseed oil being oxidized by air. Please tighten the bottle cap and put it in the refrigerator.
The ancients believed that eating flax regularly can remove all chronic diseases and have the effect of rejuvenation and immortality. If cooked with rice, it is called "Xianjia cuisine" by the people. According to scientific analysis, the main component of flaxseed is unsaturated fatty acid, accounting for 85% ~ 90%, and oleic acid and linoleic acid account for 50% respectively. It is characterized by strong stability and easy storage, because sesame oil contains a natural antioxidant-linolenic acid. Sesame oil also contains minerals such as protein, sesamin, vitamin E, lecithin, sucrose, calcium, phosphorus and iron. It is an edible oil with extremely rich nutrition.
In recent years, with the progress of science and technology, the nutritional value and health care function of flax have attracted the attention of scientists in medical, food, agriculture and other fields. A large number of research results show that linseed oil is a high-quality edible oil, rich in α -linolenic acid and a variety of unsaturated fatty acids, which can be directly converted into DHA and EPA in human body. Flaxseed oil contains 40-60% linolenic acid, which is the highest among vegetable oils and is an economical and practical "deep sea fish oil". As we all know, "fish oil" refers to EPA and DHA, which are transformed from α -linolenic acid in fish (mainly contained in seaweed). People who take α -linolenic acid (mainly contained in linseed oil) will also synthesize EPA and DHA in their bodies. Therefore, eating flaxseed oil rich in a- linolenic acid can have the effect similar to eating "fish oil"; Repair and update the unsaturated fatty acid chain of brain cell membrane, and play a role in strengthening brain, improving intelligence, reducing blood lipid, resisting platelet aggregation, dilating arterioles and preventing thrombosis. Therefore, linseed oil is really a treasure in oil!
Edible method
1, this product is mellow and delicious, and can be cooked, cold-mixed, brewed and made into soup. When cooking, the oil temperature should be avoided to exceed 70%, and the nutrients in linseed oil should be kept from being destroyed to the maximum extent. Try not to drink it alone. You can mix flaxseed oil with other foods. Only in this way can it be emulsified, thus ensuring better absorption of those essential fatty acids.
2. Adding linseed oil to breakfast drinks can prolong satiety.
3. Mix yogurt with linseed oil, which can be used as a substitute for mayonnaise or sprinkled on favorite fruits. You can also mix it with honey or make egg soup according to the ratio of 1: 1.
4. Slowly pour linseed oil into steamed vegetables and sprinkle with favorite spices.
5, can also be directly dipped in bread, cakes and other edible, mellow taste.
In fact, linseed oil can be added to any food as long as it suits your taste. The daily intake of 15~20ml per person can meet the human body's demand for 9 grams of α -linolenic acid.
At the same time, the study found that linseed oil is rich in various basic omega-3 fatty acids, which is an important fat with protective effect on the heart and can keep food in the stomach for a longer time than fat-free or low-fat foods. This is because it takes more energy to digest fat than carbohydrates and protein. In this way, the working time of the stomach is correspondingly prolonged, which urges the intestine to secrete a hormone called intestinal kinesin peptide and sends a signal to the brain to stop eating. But the most amazing thing about linseed oil is that it does not accumulate in the body in the form of fat.
Of course, omega-3 is just one of the omega fatty acids that can suppress appetite, and omega-6 and omega-9 also have the same effect. Some natural foods such as nuts, fish, olive oil and bean sprouts contain this extremely important fat.
Eating linseed oil is of great significance to human health.
With the improvement of people's material life, the incidence of "rich diseases" such as hypertension, hyperlipidemia, hyperglycemia, heart disease, cancer, obesity and sub-health is getting higher and higher. People began to pay attention to diet and eat less foods with high fat and cholesterol. But many people do have this experience. We don't eat meat or even eggs. Why is my blood fat still high? The answer is simple. We want to be healthy, but we use unhealthy oil every day.
The oil we eat every day is mainly vegetable oil (peanut oil, soybean oil, sunflower oil, corn oil, rapeseed oil, etc. ). Linoleic acid (ω-6) is the main polyunsaturated fatty acid, but linolenic acid (ω-3) is extremely scarce. It is scientifically confirmed that when the ratio of linolenic acid to linoleic acid is 1: 4 (such as virgin olive oil), the human body is in the healthiest state, and it is difficult for various external pathogens to invade. When there is too much linoleic acid and too little linolenic acid, all kinds of "rich diseases" begin to spread in the body, which is the main reason for the high incidence of "rich diseases".
From 65438 to 0993, the United Nations Health Organization and the World Food Organization advocated for the first time in the Proposal on Promoting Supplementation of α -linolenic Acid in Diets: In view of the importance of α -linolenic acid and the general deficiency of human intake, it was suggested to supplement α -linolenic acid specially. Since the 1990s, the United States, Japan, France and other countries have legislated that certain foods must be added with α -linolenic acid and its metabolites before they can be sold.
The United States Food and Drug Administration (FDA), which has always been known for its strictness, has recognized linseed oil as a healthy food rich in α -linolenic acid, and confirmed that it has the following functions:
(1) Reduce blood lipid and blood pressure;
(2) enhancing autoimmunity;
(3) preventing diabetes;
(4) Prevention and treatment of cancer;
5] lose weight;
[6] Prevention of stroke and myocardial infarction;
Once clean up the harmful substances in the blood to prevent and treat heart disease;
(8) relieving climacteric syndrome;
(9) strengthening brain and intelligence, enhancing attention and memory;
⑽ Adjuvant treatment of multiple sclerosis;
⑾ Adjuvant treatment of rheumatoid arthritis;
⑿ Used for beriberi and eczema;
(13) Prevention and treatment of constipation, diarrhea and gastrointestinal syndrome;
According to the data of the Ministry of Health, the proportion of linolenic acid and linoleic acid intake by most urban residents in China is 1: 25 ~ 35. It is suggested that each person should take 10 ~ 20g of α -linolenic acid every day to supplement the deficiency of human α -linolenic acid. Insufficient intake of linolenic acid is the cause of cell dysfunction. International medical research shows that reducing the intake of omega-6 fatty acids while increasing the intake of omega-3 fatty acids can reduce the incidence of the following diseases and slow down the severity of the following diseases: rheumatoid arthritis, asthma, chronic obstructive pulmonary disease, segmental ileum, ulcerative colitis, 1gA nephropathy, dysmenorrhea, systemic lupus erythematosus or lupus erythematosus, psoriasis, osteoporosis, gingivitis and so on.
● 1993, FAO and WHO jointly issued a statement: In view of the importance of α -linolenic acid and the general lack of human body, it was decided to promote α -linolenic acid on a global scale.
● China people generally lack α -linolenic acid in their diets: the daily intake is less than half of the amount recommended by the World Health Organization. Experts in the field of medicine and nutrition in China call for national legislation to supplement α -linolenic acid.
● 1995, FDA, the American drug and food administration, pointed out that promoting healthy edible oil can resist the harm of three killers: hyperlipidemia, hypertension and cardiovascular and cerebrovascular diseases.
Eight effects of α -linolenic acid:
A large number of basic research, epidemiological investigation, animal experiments and clinical observations show that α -linolenic acid has the following eight physiological functions, which is recognized by the international medical and nutritional circles:
1. Prevention of cardiovascular and cerebrovascular diseases: due to thrombosis and blood vessel blockage, tissues and cells can't get oxygen supplement and nutrition supply, which eventually leads to death. The coronary arteries and cerebral vessels of the heart are prone to thrombosis, causing myocardial infarction and cerebral infarction. It is known that an important factor leading to thrombosis is the platelet aggregation process. α -linolenic acid can change the fluidity of platelet membrane, thus changing the reactivity of platelet to stimulation and the number of platelet surface receptors. Therefore, the formation of thrombus can be effectively prevented.
2. Hypolipidemic: Metabolites of α -linolenic acid have moderate regulation on blood lipid metabolism, which can promote the transformation of plasma low-density lipoprotein (LDL) to high-density lipoprotein (HDL), thus reducing blood lipid and preventing atherosclerosis.
Third, reduce critical hypertension: the blood pressure between145/90 mmhg ~160/95 mmhg is called critical hypertension, and it is initial hypertension. If you use antihypertensive drugs for a long time, it will easily cause many adverse reactions. Metabolites of α -linolenic acid can dilate blood vessels and enhance their elasticity, thus lowering blood pressure.
Fourth, inhibit the occurrence and metastasis of cancer: normal somatic cells will produce lesions due to the dysfunction of the body, while cancer cells will produce a large number of diene prostaglandins, which can inhibit various immune cell functions, reduce the function of the human immune system, and make cancer cells proliferate and metastasize. Metabolites of α -linolenic acid can directly reduce the number of cancer-causing cells, weaken platelet aggregation, inhibit the production of diene prostaglandin, and restore and improve the function of human immune system, thus effectively preventing the formation of cancer and inhibiting its metastasis. Eskimos have a low incidence of breast cancer because they eat a lot of fish or other seafood. Although their fat intake is large, there are many unsaturated fatty acids, mainly n-3 fatty acids (α-linolenic acid), so the incidence of cancer is extremely low.
5. Inhibition of allergic reaction and anti-inflammatory effect: α -linolenic acid can reduce the content of arachidonic acid (AA) in polynuclear leukocytes (RMNS) and mast cell membrane phospholipids, and reduce the release of AA during allergic reaction, thus reducing the production of LT4 (leukotrienes); Metabolite EPA also competes with AA for δ 5 desaturase. α -linolenic acid has inhibitory effect on PAF (platelet aggregation activating factor), an intermediate of allergic reaction. Therefore, α -linolenic acid can inhibit allergic reaction and inflammation. Clinical research shows that the pathogenesis of psoriasis is mainly caused by the metabolic disorder of arachidonic acid, and the symptoms can be alleviated after ingesting a certain amount of EPA. A large number of animal experiments have proved that the allergic reaction of constitution is caused by the lack of food containing α -linolenic acid.
Anti-aging intransitive verb: With the increase of age, the number of various free radicals in the body is increasing, while the number and activity of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) are gradually decreasing, so the production of malondialdehyde (MDA), a metabolite of free radicals, is increasing, damaging cells and reducing the functions of tissues and organs. After taking α -linolenic acid, GSH-Px and SOD activities increased and MDA production decreased, suggesting that α -linolenic acid has anti-aging effect.
Seven, enhance intelligence: a sound brain is absolutely indispensable for fatty acids, especially α -linolenic acid, to provide the brain with the energy it needs. The reason why the human brain can engage in highly complex work is inseparable from high-quality fatty acids. /kloc-α -linolenic acid with 0/8 carbon atoms can further extend the carbon chain and increase the number of double bonds, resulting in EPA and DHA. DHA is rich in brain neurons, which is an essential substance for brain formation and IQ development.
Eight, protect vision: DHA is particularly rich in the retina, especially outside the visual cells. If it is lacking, vision will decrease and the recovery time of retinal reflex ability will be prolonged. DHA, a metabolite of α -linolenic acid, has the function of improving and protecting eyesight.
How to distinguish original linseed oil from refined linseed oil
The original linseed oil is golden in color, with a unique fragrance of plants and a strong sense of fragrance.
The taste is mellow and smooth, slightly bitter, and the aftertaste is obvious.
The refined linseed oil is light yellow in color, and the frivolous plant fragrance is very light.
The taste is frivolous and smooth, without bitterness, and the aftertaste is not obvious.
