Not all fatty acids are detrimental to the health; there are a few such as alpha-linolenic acid found in plants and nuts, and eicosapentaenoic acid or docosahexaenoic acid that can be found in fish or fish oil supplements. These essential polyunsaturated fats can be further broken down into two families, omega 3 and omega 6, and though very similar in structure, they trigger very different reactions within the body. Omega 3 provides anti-inflammatory, anti-cancerous products while also improving the cardiovascular system, while omega 6 does the exact opposite.
Considering that the body does not generate either omega 3 or 6 it is easy to understand why deficiencies and imbalanced levels of these essential fatty acids exist. In the UK, people eat higher quantities of omega 6 and scientists are discovering higher incidences of obesity, premature aging, hypertension, diabetes, heart disease some forms of cancer resulting directly from omega 6 consumption.
While omega-6 is overused in the UK, many people are deficient in omega-3. Good sources of plant based omega-3s are rapeseed, evening primrose and walnut oils, although the richest supply is found in fish oils. Surprisingly, studies have shown that cultures that have high fish consumption, such as the Chinese or other Asian cultures, also show lower triglyceride levels, improved memory and learning skills, lower instances of depression, bipolar disorder and ADHD syndrome.
Omega-3 fatty acids found in fish oil helps maintain the nerve cells in the area of the brain which helps preserve the memory and this keeps the brain from deteriorating with age. When the brain begins to lose cells it leads to the development of Alzheimer's disease and dementia. In the January edition of Neurology, Dr James Pottala from the University of South Dakota in Sioux Falls, US, discovered a 0.7% increase in overall brain size in those who doubled omega-3 intake.
Rachel Moore of Vitamin Planet commented:
Nutritionists recommend two portions of fish a week, including one of oily fish such as mackerel, herring and tuna, to increase omega 3 intakes. Fish oil supplements and omega 3 supplements can also supply sufficient omega 3 doses to counteract the effect of omega 6.
