α -linolenic acid is absolutely indispensable to human body and plays an extremely important role in human health. α -linolenic acid is a polyunsaturated fatty acid and an essential fatty acid. α -linolenic acid is the core substance of life, an important component of human brain cells and tissue cells, and a nutrient needed every day in human life. α -linolenic acid cannot be synthesized by the human body itself, nor can it be synthesized by other nutrients. Must be obtained through diet. α -linolenic acid belongs to ω-3 series (or n-3 series) fatty acids. After entering the human body, it is converted into EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid, docosahexaenoic acid) under the catalysis of enzymes (dehydrogenase and carbon chain extender), and thus it is absorbed. α -linolenic acid, EPA and DHA are collectively referred to as ω-3 series (or n-3 series) fatty acids, α -linolenic acid is the precursor or parent, while EPA and DHA are the precursors or derivatives of α -linolenic acid.
α -linolenic acid is a kind of food in edible oil, but it is a kind of health care product when it is made into capsules. α -linolenic acid mainly exists in linseed oil and perilla seed oil. Many scientists have proved that excessive intake of saturated fatty acids and trans fatty acids are the direct causes of cancer, cardiovascular and cerebrovascular diseases and other diseases, and increasing intake of α -linolenic acid can significantly change this state. The basic functions of α -linolenic acid are: enhancing intelligence, enhancing immunity, protecting eyesight, lowering blood fat, lowering blood pressure and blood sugar, inhibiting hemorrhagic brain diseases and thrombotic diseases, inhibiting the occurrence and metastasis of cancer, preventing myocardial infarction and cerebral infarction, preventing allergic diseases, preventing inflammation and delaying human aging. α -linolenic acid is beneficial to the prevention and treatment of cancer, cardiovascular and cerebrovascular diseases, diabetes, rheumatoid diseases, dermatitis, depression, schizophrenia, Alzheimer's disease, allergy, asthma, kidney disease and chronic obstructive pneumonia. Once the human body lacks α -linolenic acid, it will cause disorder of lipid metabolism, leading to decreased immunity, forgetfulness, fatigue, decreased vision, atherosclerosis and other symptoms. Especially infants and adolescents, if they lack α -linolenic acid, it will seriously affect their intelligence and vision development. α -linolenic acid is beneficial to brain health and intelligence. α -linolenic acid is an essential factor for maintaining brain and nerve functions. It is worth noting that about 60% of the human brain is composed of fat, nerve growth needs α -linolenic acid as raw material, and nerves and neurons need α -linolenic acid to provide energy. DHA is a derivative of α -linolenic acid and an important substance in the brain. It can promote the synthesis of protein and monoamine neurotransmitters in the brain, and play an important role in the formation, growth, proliferation, differentiation and maturation of brain neurons, glial cells and nerve conduction synapses. It can improve the permeability of brain nerve membrane and presynaptic membrane, make the nerve information transmission path smooth, improve the nerve reflex ability, and then enhance people's thinking ability, memory ability and stress ability. α -linolenic acid is necessary to improve children's intelligence and prevent brain aging in the elderly. For students, the brain must get enough DHA to have good intelligence and memory ability, otherwise even if you study hard, brain cells will not be well stimulated and grown, so you must take enough α -linolenic acid every day to effectively improve your academic performance.
For pregnant women and young children, it has the same brain-strengthening effect. If pregnant women lack DHA, the number of fetal brain cells will inevitably be insufficient, which will lead to mental retardation or abortion in severe cases. Therefore, pregnant women must get enough α -linolenic acid and transport its derivative DHA to the fetal brain through the mother, which plays an extremely important role in the early development of the fetal brain. α -linolenic acid has anticancer effect. The researchers found and isolated a substance that caused cancer patients to lose weight, and were surprised to find that the activity of this substance was controlled by EPA, a derivative of α -linolenic acid. This substance is called "Fachfilock factor" and is produced by some stubborn tumors. It uses fat to supply tumors, promotes tumor growth and makes patients lose weight. EPA can control the activity of "Fachfilock factor", thus controlling the emaciation of cancer patients and shrinking tumors.
α -linolenic acid can reduce blood lipid and blood pressure. It has been proved that α -linolenic acid can reduce serum total cholesterol, triglyceride, low density lipoprotein and very low density lipoprotein, and increase serum high density lipoprotein. α -linolenic acid is very effective for borderline hypertension, and it still has antihypertensive effect on hypertension or hemorrhagic stroke. Its antihypertensive mechanism is that α -linolenic acid can reduce neutral fat (cholesterol and triglyceride) in plasma, so it can lower blood pressure, thus inhibiting thrombotic diseases and preventing myocardial infarction and cerebral infarction. Through many practices, it is known that cooking with blended oil containing α -linolenic acid can significantly improve human immunity, effectively prevent colds and avoid other complications after about half a year to one year.
Linseed oil is the vegetable oil with the highest content of α -linolenic acid in the world, and the α -linolenic acid content in linseed oil is ≥5 1%-65%. Flaxseed is "homology of medicine and food", and flaxseed is an item on the list of "homology of medicine and food" approved by the Ministry of Health. "Compendium of Materia Medica" contains flax: "flax, nourishing five internal organs, nourishing marrow and strengthening brain, benefiting qi, removing fat, preserving acidity and saltiness, promoting granulation, moistening dryness and expelling wind; Treat skin itching, leprosy, dizziness and constipation. " The World Health Organization (WH0) and the Food and Agriculture Organization of the United Nations (FAO) jointly issued a statement in 1993. In view of the importance of α -linolenic acid and the general lack of human beings, they decided to promote α -linolenic acid on a global scale. The World Health Organization (WHO), the Ministry of Health of the People's Republic of China and the Nutrition Society of China all agreed in 2000 that α -linolenic acid is the only essential fatty acid in the omega-3 series. Many countries in the world, such as the United States, Britain, France, Germany, Japan and other countries, have legislated that designated foods must be added with α -linolenic acid and its metabolites before they can be sold. Our people are generally short of α -linolenic acid, and their daily intake is less than half of the recommended amount of 1.25g per person per day by the World Health Organization. At present, the understanding of α -linolenic acid in China is not enough, and the use of α -linolenic acid is extremely rare. Experts call on national legislation to supplement α -linolenic acid. In ordinary food, the content of α -linolenic acid is very small. Only a few foods such as perilla seed, flaxseed, perilla seed, hemp seed, walnut, silkworm chrysalis and deep-sea fish are rich in α -linolenic acid and its derivatives. The most ideal food or health products rich in α -linolenic acid are perilla seed oil, perilla seed oil, linseed oil (or linseed oil) and α -linolenic acid capsules. It is a very good choice to use edible blending oil containing α -linolenic acid for cooking in daily life.
1999, the state planning commission officially approved the flax seed comprehensive development and utilization project as a national high-tech industrialization demonstration project (approval number: Ji 1999. 1429), and the state invested 220 million yuan to build the world's largest organic flax planting base and established Inner Mongolia. Pure physical ultra-low temperature extraction technology makes the production process of products free of any chemical additives and chemical residues. Unique biological activity maintenance technology, extracting α -linolenic acid in living form, completely retaining the biological activity of α -linolenic acid, which is convenient for human body to absorb and utilize and can be stored for a long time at room temperature. The quality of linseed oil and α -linolenic acid, the main products, far exceeds that of similar products in the world. It has successively obtained more than 20 honors and certifications, including national patents 13, scientific research achievements 120, and "national quality and integrity AAAAA brand enterprise", "organic certification of international environmental protection organizations" and "non-genetically modified food".
In 2009, the state allocated 600,000 mu of land again to further support the project construction, and the relevant state leaders also made special instructions, requiring the project undertaker to make careful planning, scientific arrangement, careful organization and careful guidance, so as to achieve practical results. The balanced relationship between human physiological needs and food nutrition supply is nutritional balance (or nutritional balance). That is, the balance of calories and nutrients (carbohydrates, fats and protein can provide calories for human body, so they are called calories and nutrients), the balance of amino acids, the balance of acid-base and the balance of various nutrients intake. Only by maintaining a nutritional balance can it be beneficial to the absorption and utilization of nutrients. If the balance relationship is unbalanced, that is, food nutrition does not meet human physiological needs, it will have a negative impact on human health, and even lead to some nutritional diseases or chronic diseases. With the improvement of people's material life today, the balance of fatty acids in nutritional balance is extremely important.
The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) solemnly recommend: saturated fatty acids: monounsaturated fatty acids: polyunsaturated fatty acids =1:1,which is the most authoritative recommended value in the world at present. Among them, polyunsaturated fatty acids include linoleic acid and α -linolenic acid. Although linoleic acid is also an essential fatty acid, the intake of human body is already excessive. For example, people often eat soybean oil, in which linoleic acid content is about 60%. Linoleic acid and α -linolenic acid in human body have to compete for the same enzyme to be transformed and absorbed after transformation. If linoleic acid is eaten too much, α -linolenic acid can't be converted by enough enzymes and can't be absorbed naturally. Therefore, the intake ratio of linoleic acid and α -linolenic acid should be controlled. In 2000, the recommended standards of China Nutrition Society were: ω-6 (linoleic acid): ω-3(α- linolenic acid) = 4: 1, and ω-6 for other (pupils, teenagers, adults and the elderly).
WHO recommended standard: ω-6: ω-3 should be less than 6: 1. Experts from Harvard Medical School believe that the optimal ratio of ω-6 to ω-3 in human body is 1: 1, but modern humans have seriously deviated from 25: 1 or even 30: 1. Nowadays, all kinds of edible blended oils containing α -linolenic acid are put on the market continuously, which not only becomes an essential edible oil for consumers, but also becomes the first choice for preventing cardiovascular and cerebrovascular diseases. In the process of guiding people's edible oil consumption to change from nutrition to health, it is bound to trigger a new revolution in human edible oil. An unscientific diet can make people eat diseases, while a scientific diet can certainly make people eat health. As long as we believe in science and change backward eating habits according to scientific laws, people's health will surely become healthier and healthier.
The characteristics of α -linolenic acid are introduced. α -linolenic acid is called an essential fatty acid to maintain human evolution and enhance health. It is the mother of N-3 series unsaturated fatty acids and the most basic and primitive substance in the process of life evolution. Human brain organs contain about 10% α -linolenic acid and its metabolites, and human retina and nervous system also contain a lot of α -linolenic acid and its metabolites. If α -linolenic acid is deficient, the functional efficiency of these organs will decrease. The optimum ratio of N-3 unsaturated fatty acids to other fatty acids is 1:5, which is called breast milk ratio, while the ratio of unsaturated fat to saturated fatty acids in edible oil in daily life is greater than 1:25.
