Function and edible method of flaxseed oil

On land, there is nothing more brain-nourishing than linseed oil; Linseed oil can be called "student food" or "intellectual food". Its cell matrix contains lignans, and its content is 100-800 times higher than that of other commonly used cereals and beans. Flaxseed also contains 18 amino acids, 3 vitamins (A, E, B 1) and 8 trace elements which are essential for human body. Flax oil is mainly composed of α -linolenic acid, 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 an increase in the incidence of modern diseases such as hypertension, hypertension and cancer.

Efficacy of linseed oil:

1, has anti-inflammatory, antithrombotic, antiarrhythmic, blood lipid lowering, blood sugar lowering, blood carbuncle lowering, cholesterol lowering, blood cleaning, blood vessel cleaning and vasodilation, and can prevent diabetes, hypertension, stroke and myocardial infarction.

2. It has the functions of supplementing brain cell nutrition, promoting intellectual development, improving memory, preventing brain atrophy and senile dementia, improving stress resistance, and reducing depression and insomnia.

3. It has anticancer, antifungal and antiallergic effects.

4. It has the functions of strengthening body-building, enhancing skin softness, luster and elasticity, improving immunity, reducing grease 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 has a pure taste. In order to obtain the best nutrition and taste, it can be drunk directly or eaten with other foods. Please avoid heating at high temperature.

Please put it in the refrigerator after opening the bottle, so as to reduce the chance of oxidation of flaxseed oil when it comes into contact with air. Please fasten 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 it is cooked with rice, it is called "Xianjia food" by the people. According to scientific analysis, the main component of flax seed 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, iron, etc. 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 many fields such as medical treatment, food and agriculture. A large number of research results show that linseed oil is a high-quality edible oil, rich in α -linolenic acid and various 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 in vegetable oil and is an economical and practical "deep sea fish oil". As we all know, "fish oil" refers to EPA and DHA, which is changed from α -linolenic acid (mainly contained in seaweed) in fish. People taking α -linolenic acid (mainly contained in linseed oil) will also synthesize EPA and DHA in the body. 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 nerve cell membrane, and play a role in strengthening the brain, promoting 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 used for cooking, cold mixing, stuffing mixing and soup making. When cooking, the oil temperature should be avoided to exceed 70%, so as to keep the nutrients in linseed oil from being destroyed to the maximum extent. Try not to drink it alone, but 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 at the ratio of1:1.

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 own 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 all kinds of basic omega-3 fatty acids, which is an important fat with protective effect on the heart and can keep food in the stomach longer than fat-free or low-fat foods. This is because it takes more energy to digest fat than to digest carbohydrates and protein. As a result, the working hours of the stomach are correspondingly prolonged, which promotes the secretion of a hormone called enterokinesin peptide from the intestine 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 omega fatty acids that can suppress appetite, and omega-6 and omega-9 also have the same effect. Some natural foods, such as some 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, sub-health and so on is getting higher and higher. People begin 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, even eggs. Why is my blood lipid still high? The answer is simple. We want to be healthy, but we use unhealthy oil every day.

The oils we eat every day are mainly vegetable oils (peanut oil, soybean oil, sunflower oil, corn oil, rapeseed oil, etc.). Among the polyunsaturated fatty acids, linoleic acid (ω-6) is the main one, but linolenic acid (ω-3) is extremely scarce. It is scientifically confirmed that when the ratio of linolenic acid to linoleic acid is1:4 (such as virgin olive oil), the human body is in the most healthy state, and it is difficult for various external germs 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".

1993 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 in 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 α -linolenic acid and metabolites must be added to certain foods before they can be sold.

The American Food and Drug Administration (FDA), which has always been known for its strictness, has determined that linseed oil is a healthy food rich in α -linolenic acid, and it has been confirmed that it has the following functions:

(1) lowering blood lipid and blood pressure;

(2) enhancing autoimmune;

(3) prevention of diabetes;

(4) Prevention and treatment of cancer;

5] lose weight;

[6] Prevention of stroke and myocardial infarction;

Once clean up harmful substances in the blood and prevent and treat heart disease;

(8) alleviating menopausal syndrome;

(9) strengthening the mind and brain, enhancing attention and memory;

⑽ Adjuvant treatment of multiple sclerosis;

⑾ Adjuvant treatment of rheumatoid arthritis;

⑿ Used for dermatophytosis and eczema;

(13) Prevention and treatment of constipation, diarrhea and gastrointestinal syndrome;

According to the data of Chinese Ministry of Health, the proportion of linolenic acid and linoleic acid consumed by most urban residents in China is1:25 ~ 35. It is suggested that each person should take α -linolenic acid10 ~ 20g 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 worldwide.

● There is a general lack of α -linolenic acid in the diet of Chinese people: the daily intake is less than half of the amount recommended by the World Health Organization. Experts in the medical and nutritional fields in China have called for national legislation to supplement α -linolenic acid.

● 1995, FDA, the American medicine and food management agency, 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 are recognized by the international medical and nutritional circles:

1. Prevention of cardiovascular and cerebrovascular diseases: Due to thrombosis, blood vessels are blocked, tissues and cells can't get oxygen supplement and nutrient supply, which will eventually lead to death. Thrombosis is easy to form in coronary arteries and cerebral vessels of the heart, causing myocardial infarction and cerebral infarction. It has been known that an important factor contributing to thrombosis is the process of platelet aggregation. 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. Lowering blood lipid: Metabolites of α -linolenic acid have a moderate regulating effect on blood lipid metabolism, and can promote the transformation of plasma low-density lipoprotein (LDL) to high-density lipoprotein (HDL), so as to reduce blood lipid and prevent atherosclerosis.

Third, reduce critical hypertension: blood pressure between145/90 mmhg ~160/95 mmhg is called critical hypertension, which is initial hypertension. If antihypertensive drugs are used 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 because of the imbalance of body functions, while cancer cells will produce a large number of diene prostaglandins that can inhibit various immune cell functions, reduce the function of human immune system, and enable cancer cells to proliferate and metastasize. Metabolites of α -linolenic acid can directly reduce the number of cancer-causing cells, weaken platelet agglutination, inhibit the production of diene prostaglandin, and restore and improve the function of human immune system, thus effectively preventing cancer formation and inhibiting its metastasis. The incidence of breast cancer in Eskimos is very low 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 when allergic reaction occurs, thus reducing the production of LT4 (leukotriene); 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 has inhibitory effect on 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 hyperallergic reaction of constitution is caused by the lack of food containing α -linolenic acid.

Vi. Anti-aging: 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, which damages cells and reduces the functions of tissues and organs. After taking α -linolenic acid, GSH-Px and SOD activities increased and MDA production decreased, which revealed that α -linolenic acid had anti-aging effect.

Seven, enhance intelligence: a sound brain is absolutely indispensable for fatty acids, especially α -linolenic acid, which provides 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 to produce EPA and DHA. DHA is abundant in brain neurons, which is an essential substance for brain formation and IQ development.

Eight, protect vision: DHA is particularly abundant in the retina, especially outside the optic cells. If it is lacking, vision will decline and the recovery time of retinal reflex ability will be prolonged. DHA, a metabolite of α -linolenic acid, can improve and protect eyesight.

How to distinguish original flaxseed oil from refined flaxseed oil

The original flaxseed oil is golden in color, and has a plant-specific fragrance with a strong sense of fragrance.

The taste is mellow and smooth, slightly bitter, with obvious aftertaste.

Refined linseed oil is light yellow in color, and the fragrance of plants with frivolous fragrance is very light.

The taste is frivolous and smooth, without bitterness, and the aftertaste is not obvious.
