Just as omega-3 fatty acids, omega-6 fatty acids are polyunsaturated fatty acids. Omega-6 fatty acids will also be essential, so you will need to acquire them from your diet. These fats are primarily used for energy.
Although omega-6 fats are necessary, the present day Western diet contains much more omega-6 fatty acids than necessary. The recommended ratio of omega-6 to omega-3 fatty acids in the dietary plan is 4:1 or less. However, the modern diet has a rate between 10:1 and 50:1. Therefore, although omega-6 fats are necessary in the proper quantities, many people in the developed world should aim to reduce their omega-6 intake.
