Omega 3 : omega 6 – the rise of chronic disease and illness

Saturday, September 22nd, 2012

The human body can synthesise all fatty acids with the exception of omega3 and omega 6 . They are known as essential fatty acids or EFA’S they are the building blocks of cell membranes – brain tissue and nerve tissue – they are essential for the functioning of every cell in your body .They help protect against chronic health conditions and disease , they repair degenerative cells and ensure that the body is fuelled properly . The ideal scenario would be to have a ratio of 1:1 omega 6 : omega 3 this however as we shall see is not the case and the actual ratio in UK , USA , UAE and countries following a westernised diet maybe as much as 25 : 1 omega 6 : omega 3 .

To put this in perspective taking breast cancer as an example studies have shown that an excessive food based intake of Omega – 6( linoleic acid ) is linked to some forms of breast cancer , in subjects whose breast tissue contains high levels of omega-3 they appear to be less prone to this form of cancer which affects 1 in 8 women.

In order to maintain levels of these very important EFA’s you have to take them from food sources – what has happened in the last Century is that there has been an increase in the consumption of Omega 6 (linoleic acid) and a decrease in consumption of Omega 3 ( alpha linoleic acid )

Fats can be divided into two groups saturated and unsaturated fatty acids . Saturated fats are from animals sources , unsaturated fats are your omega 3 , omega 6 and omega 9 . Omega 9 is also known as Oleic acid .

Omega 6 is converted in your body into arachodonic acid (AA) Omega 3 is converted into eicosapentaenoic acid (EPA ) and docosahexaenoic acid (DHA) the secret to good health is to have a balance between the omega 6 and omega 3 . Unfortunately in our modern diet we consume too much omega 6 and too little omega 3 and it is this inbalance that has resulted in so many of the health problems affecting the population . Part of the problem is the intense farming methods and what we feed animals on as well as that a lot of fish in fish farms are fed an artificial diet so the farmed fish contains less omega 3 than wild cold water fish which feeds on krill . The most common source s of omega 6 in our modern diet is sunflower oil , corn oil , groundnut oil , hemp , safflower and soya oils . These oils are used extensively in the modern food industry just look at the labels of the food you buy – bread , pizza, margarines , ready meals .

A diet high in omega 6 is one that is pro inflammatory – this is due to the fact your body produces more prostaglandins which promote inflammation – inflammation is what precedes disease and many diseases are aggrevated by inflammation ie arthritis , type 2 diabetes , IBD , psoriasis etc . With the western diet showing a ratio of around 25: 1 omega 6 (pro inflammatory ) : omega 3 (anti inflammatory ) it is easy to see what has gone wrong and why we have the increase in so many chronic conditions .

The simple solution is obviously to increase intake of the anti inflammatory omega 3 – EPA and DHA and decrease intake of the pro inflammatory omega 6 sunflower oils , corn oil etc . Very often the simplest way is for most people is to take an omega3 supplement however due to the clever marketing of the companies finding the right supplement is difficult .

You need a supplement that is high in active ingredients specifically EPA which is believed to be the most potent natural anti inflammatory . Takeomega3 has 800mg EPA per capsule which is far in excess of any other omega3 product on shelf – surprisingly the brands advertising 1000mg omega3 are only 30% active ingredients and the other 70% is fat which you dont need !! ., TakeOmega 3 is 90% active ingredients. Research has shown that for an omega3 supplement to be effective it needs to be 80% active ingredients none of the brands on UK shelves offer this . They label highest concentration , pure omega3 , 1000mg omega3 but at the end of the day they are lowin the active ingredients and as a result are not effective . Why waste money on a product that could be as much as 80% fat that you dont need ?

Omega-3 Fish Oil EPA and DHA Intake Linked With Reduced Risk of Age-Related Macular Degeneration in Women

Wednesday, July 13th, 2011

Regular consumption of fish and omega-3 fatty acids found in fish is associated with a significantly reduced risk of developing age-related macular degeneration in women, according to a report posted online that will appear in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

An estimated nine million U.S. adults aged 40 years and older show signs of age-related macular degeneration (AMD),” the authors write as background information in the article. “An additional 7.3 million persons have early age-related macular degeneration, which is usually associated with moderate or no vision loss but does increase the risk of progression to advanced age-related macular degeneration.”
Using the Women’s Health Study, William G. Christen, Sc.D., of Brigham and Women’s Hospital and Harvard Medical School, Boston, and colleagues collected data on 38,022 women who had not been diagnosed with age-related macular degeneration. Information on women’s eating habits was obtained via questionnaire at the beginning of the study and included information on intake of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) [Omega-3 fatty acids found in fish], and arachidonic acid and linoleic acid (omega-6 fatty acids). During ten years of follow-up, additional questionnaires tracked the women’s eye health, with specific focus on diagnosis of age-related macular degeneration.
Over the course of follow-up, 235 cases of age-related macular degeneration were reported. In analyses that adjusted for age and treatment assignment, women who consumed the most DHA compared with women who consumed the lowest amount had a 38 percent lower risk of developing age-related macular degeneration. Similar results were observed for higher intake of EPA and for higher consumption of both types of acid together.
Results for fish intake showed that consumption of one or more servings of fish per week, when compared to less than one per month, was associated with a 42 percent lower risk of age-related macular degeneration. “This lower risk appeared to be due primarily to consumption of canned tuna fish and dark-meat fish.”
For omega-6 fatty acids, higher intake of linoleic acid but not arachidonic acid was associated with an increased risk of age-related macular degeneration, however this association was non-significant after adjustment for other risk factors and fats.
“In summary, these prospective data from a large population of women with no prior diagnosis of AMD indicate that regular consumption of DHA and EPA and fish significantly reduced the risk of incident AMD,” the authors conclu
