Essential fats are fats that we need them to survive and our bodies can not produce them but we have to add these fatty acids through our diets. The polyunsaturated fatty acids: omega 3 and omega 6 are both essential. Today omega-6 is often presented as bad fats and omega-3 as good. This is not true. But the relationship and balance between them is very important. Omega-6 acids are used for processes that increase inflammation in the body. Processes like blood clotting, and cell proliferation. Omega-3 fatty acids on the other hand decrease those functions. The balance is very important.
For optimal health the relationship should be 1 i.e. we should have equal amount of omega 3 fats and omega 6 fats in our diet. But in reality today in Europe and North America the relationship is around 50. So we eat 50 times more omega-6 fats. This imbalance may explain the increase of diseases as asthma, heart disease, many forms of cancer, autoimmunity and neurodegenerative diseases. The imbalance between omega-3 and omega-6 fatty acids can also contribute to obesity, dyslexia, depression and hyperactivity.
