The balance between acids Essential Fatty is a solemn event for the life of the cell: this balance can be disrupted at any time of life, our life is measured continuously with Nature, which is a boundless ocean of investigation that unfolds before us as problem. (George Perry)


Essential Fatty Acids (AGE)

Among the unsaturated fats, there are two that are necessary for the human body, so they are defined Essential Fatty Acids (AGE) or EFA (Essential Fatty Acids) . Sometimes they are also called Vitamin F . Are considered essential because the human body does not può generare, pertanto, per evitare disturbi da carenza, occorre assumerli con il cibo.
Questi due grassi essenziali sono l' Acido Linoleico e l' Acido Alfa-Linolenico . Da essi, attraverso complesse trasformazioni prodotte da alcuni enzimi, derivano altri AGE definiti PUFA (Polinsatured Fatty Acids) .
L' Acido Linoleico e l' Acido Alfa-Linolenico sono necessari per la formazione delle membrane cellulari, il corretto sviluppo e funzionamento del sistema nervoso e del cervello. I loro derivati sono i precursori di sostanze simili agli ormoni chiamate Eicosanoidi (Prostaglandine, Thromboxanes, leukotrienes). These organic substances regulate numerous activities, among which are: blood pressure, blood viscosity, vasoconstriction, immune and inflammatory reactions.
The need for essential fatty acids in adults is not very high and is easily met by a varied diet. Children, however, require especially linoleic acid for their growth. It should be noted that AGE are destroyed by the process of hydrogenation that is used to give more texture to vegetable oils and, nota bene, to produce margarine.



Essential Fatty Acids (AGE), are divided into the following two series:

  1. omega-6 series, which starts with ' linoleic acid (LA) ( plant origin).
    • gamma-linolenic acid (GLA)
    • homogamma-of-linolenic acid (DGLA)
    • Arachidonic acid (AA)
    • (More details)
  2. Series Omega-3 , which starts with ' alpha-linolenic acid (LNA) (derived from fish).
    • eicosapentaenoic acid (EPA)
    • Acido docosapentenoico
    • Acido docosaesaenoico (DHA)
    • (Maggiori dettagli)


Note

  1. Per ottenere questi importanti derivazioni è necessario che sia funzionalmente valido un enzima chiamato "Delta 6 Desaturasi" che, purtroppo, può essere depresso nel suo funzionamento dai seguenti fattori:
    • Alimentari : digiuno, glucosio, fruttosio, glicerina, grassi saturi, grassi idrogenati, colesterina, scarsità di proteine, scarsità di zinco, eccesso di Acido linoleico .
    • Ormoni : glucagone, adrenalina, glucocorticoidi, tirosina.
    • Varie : fumo, età avanzata, età neonatale, alta temperatura, radiazioni ionizzanti.
  2. Se nella dieta i grassi saturi superano di molto quelli essenziali possono subentrare alcune patologie del seno ed alterazioni del ciclo mestruale.
  3. Gli acetilsalicilati, gli antiartritici, il cortisone e i beta-bloccanti, inibiscono la produzione degli acidi grassi derivati della Serie Omega-3 .


Importanza degli Acidi Grassi Essenziali (AGE)

Gli AGE risultano assai importanti to
  • processes involved in growth,
  • the formation processes of the cell membrane,
  • the synthesis of hemoglobin,
  • the proper functioning of the thyroid, adrenal and various mucous membranes,
  • the duties attached to sex and reproduction,
  • produce energy,
  • act as adjuvants in the treatment of skin diseases (psoriasis, etc..), cellulite and edema,
  • preventing increases in blood pressure, thin the blood
  • maintain and monitor coagulation,
  • modulate the activity of the immune system, facilitating the healing of wounds and infections,
  • maintain healthy cell membrane and that of mitochondria,
  • keep the skin soft and supple, elastic
  • keep the wall of blood vessels (arteries, veins and capillaries),
  • prevention of bronchial asthma and rheumatoid arthritis ,
  • reduce cholesterol by preventing excessive build-up on artery walls,
  • vitalize the cells of the central nervous system (CNS).
  • increase protein synthesis of liver mitochondria and contribute to the regeneration of liver cells.

damage from lack : retarded growth, weakness and immune deficiency, possible sterility, transporting unstable degli ioni attraverso la membrana cellulare, alterazioni della pelle (eritema e desquamazione del cuoio capelluto, caduta di peli e capelli), carenza nella produzione di prostaglandine e particolari acidi grassi che sono presenti nel cervello, nei reni, nella prostata e nel liquido seminale e mestruale.
Danni da eccesso : predisposizione alle emoraggie, disfunzioni del sistema immunitario, intossicazione, interferenze con la vitamina E.


Importanza dei PUFA (Polinsatured Fatty Acids)

I PUFA (Polinsatured Fatty Acids) sono gli acidi grassi derivati da quelli essenziali ( AGE ). Nell'organismo servono per alcune importanti funzioni tra cui:

  • sviluppare il tessuto nervoso dei neonati. Qualora carenti possono causare problemi alla vista o al sistema nervoso centrale; questo vale anche per gli adulti,
  • controllare l'aggregazione delle piastrine del sangue,
  • evitare alcune malattie della pelle (dermatiti e eczema atopico),
  • facilitare una miglior tolleranza ai carboidrati nelle persone affette da diabete,
  • mantenere la pelle in buona salute,
  • mantenere riflessi pronti e un sistema nervoso in perfetta forma,
  • regolare l'equilibrio delle prostaglandine,
  • ridurre il colesterolo qualora fosse eccessivo.


Metabolismo dell'Acido linoleico (Omega-6)

  • Inizio della Serie Omega-6 con l'Acido linoleico
    • Fonti: olio di enotera (70%), olio di cynara (57%), olio di mais o girasole (56%), olio di soia (52%)
  • enzima delta-6-desaturasi
  • Acido gamma-linolenico (GLA)
  • allungamento
  • Acido di-homogamma-linolenico (DGLA) - genera Ecosanoidi "buoni" come le Prostaglandine della Serie 1
  • enzima delta-5-desaturasi
  • Acido arachidonico (AA) - genera Eicosanoids "bad" (such as PGE2 and TxA2) and the good ones (such as prostacyclin, prostaglandins Series 2).


Metabolism of alpha-linolenic acid (Omega-3)

  • Series Start with Omega-3 Alpha-linolenic acid
  • enzyme delta-6-desaturase
  • acid eicosatetraenoico
  • enzyme delta-5-desaturase
  • eicosapentaenoic acid (EPA) - Series 3 prostaglandins ggenera
  • enzyme delta-4-desaturase
  • docosahexaenoic acid (DHA)


eicosanoids

Eicosanoids are substances (superormoni) that control the hormonal system. They are represented by different families of substances (prostaglandins, thromboxanes, leukotrienes, lipoxins, etc...) We need researchers Bergstrom, Samuelson and Vane (Nobel Prize 1982) a valid study of these elmenti that allows us to understand its importance. The
eicosanoid derived from ' arachidonic acid (AA) ( Omega-6) have the ability to increase allergic reactions, cell proliferation, blood pressure, inflammatory reactions, aggregation platelet thrombogenesis and vasospasm.
those derived from ' eicosapentaenoic acid (EPA) ( Omega-3), have opposite effects.


Prostaglandins

The Prostaglandins are part of the family of Esonoidi and present themselves as hormonal substances. They manage imported functions such as cell permeability, coagulation, nervous system function, sexual function and reproductive fat mobilization, capillary fragility and vasoconstriction, immune and inflammatory responses. The
Prostaglandins, unlike hormones are synthesized and operate the place where they are needed. They are usually divided into three groups:

  1. Series 1 (PGE1) , considered "good", derived from ' dihomo-gamma-linolenic acid (DGLA)
  2. Series 2 (PGH2) , consider "bad", derived from ' arachidonic acid (AA)
  3. Series 3 (PGI2) , considered "good", derived from' eicosapentaenoic acid (EPA)

While prostaglandins of the 1 Series and 3 :

  • are vasodilatory,
  • collaborate to coagulation process management,
  • play-inflammatory action,
  • lowering LDL (low density lipoproteins) (low-density proteins that carry fat mainly phospholipids and free cholesterol), increase the
  • Cholesterol HDL (high density lipoproteins) (proteins that carry fat high density phospholipids and esterified cholesterol to the liver where it is eliminated through the bile. The esterification is a reaction between an alcohol and an acid.

those Series 2 of have the opposite effect.



Va precisato che gli AGE della serie Omega-6 e Omega-3 non sono intercambiabili; pertanto è necessario che vengano entrambi assunti con l'alimentazione. Non solo, ma va tenuto presente che gli Omega-6 e gli Omega-3 competono tra loro per l'utilizzo degli enzimi coinvolti nella loro desaturazione. Per tale ragione il consumo eccessivo di cibi ricchi in acidi grassi Omega-6 può compromettere la conversione dell'Acido Alfa-linolenico in Acido eicosapentenoico (EPA), e creare dei presupposti per disfunzioni o malattie.
Le ricerche attuali suggeriscono che i livelli di AGE, e il loro equilibrio, possano play a key role in the growth and development. It also seems that may be crucial in the prevention and treatment of chronic diseases including: coronary artery disease, hypertension, diabetes mellitus type II, arthritis, cancer and other immune and inflammatory disorders.
fatty acids Omega-3 series, and in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are very important for health. Unfortunately, in common foods if they are of very small quantities, the only foods that contain them are fish and dairy products.
For this, the traditional diet are used as many as 10 parts of Omega-6 against a single part of Omega-6 (ratio Omega-6/Omega-3 = 10:1), while it should be about 6:1. To correct this ratio is necessary to consume more foods that contain alpha-linolenic acid
