Arachadonic Acid is a omega 6 fatty acid that is the building block for potent inflammatory hormones and cancer promoting chemicals. This fatty acid is abundant in organ meat, egg yolk, red meat and poultry. It can also be produced from high glycaemic carbohydrates and omega 6 oils such as sunflower oil. If you flood your body with these food groups, your cells contain too much Arachidonic Acid which will lead to chronic inflammation.
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are essential Omega 3 fatty acids. EPA is the building block for anti-inflammatory hormones and anti-cancer promoting chemicals and DHA is the building block for resolvins, molecules that stimulate the resolution (clearing) of inflammation. Only the activated form of Omega 3 ie EPA and DHA has theses functions and can only be consumed through oily fish. Other plant forms of Omega 3 (flaxseed) has to undergo various biological processess to turn it into EPA and DHA. These processess do not function well in the human body and slows down even further with ageing.
With industrialisation of our food, we consume excess amounts of high glycaemic foods and omega 6 oils and too little fish (omega 3) to balance this. The optimal AA to EPA ratio is 2, but a study into obesity in Italian children has revealed a AA/EPA ratio of 30 which is similar for the average American at 35. And we wonder why the world is faced with obesity, diabets, heart disease, Alzheimer and cancer!.
