Linoleic Fatty Acid (Omega 6)


Omega 6 is the common name linoleic fatty acids, whose scientific name is: 18:2 9c, 12c (n-6). It is termed essential fatty acid because the body can not synthesize by itself (unlike other fatty acids of the n-6).

Omega 6 play an important role in the proper functioning of the immune nervous and cardiovascular systems, as well as in allergic and inflammatory reactions and wound healing.

Synthesis of the scientific literature, it appears that an intake of linoleic acid from 3 to 4% of the energy content of the diet is necessary to prevent any manifestation of deficiency.

The value of 4% (which corresponds to the 100% value in the ANC Nutrimeter ®) corrrespond for adults with a need to 10g per day of linoleic acid.

The Omega 6 / Omega 3 ratio should strive to 5 because of the desirable limit of linoleic acid and the interest of an adequate intake of α-linolenic acid.
