Omega-6 Fatty Acids are recommended

The American Heart Association recommends that people aim for at least 5 percent to 10 percent of calories from omega-6 fatty acids. [1,2] The source for these fatty acids include nuts, cooking oils and salad dressings.

In the cells that form the lining of blood vessels, omega-6 polyunsaturated fatty acids, such as linoleic acid, have anti-inflammatory properties, suppressing the production of adhesion molecules, chemokines and interleukins - all of which are key mediators of the atherosclerotic process. [1] However, Some research has suggested that omega-6 fatty acids may actually increase cardiovascular risk because they promote inflammation. Concern stems from the fact that the primary omega-6 in food is linoleic acid, which can be converted to arachidonic acid -- a substance involved in the early stages of inflammation. [2]

Observational studies demonstrated that people who ate the most omega-6 fatty acids usually had the least heart disease. [1]

Omega-6 and omega-3 polyunsaturated fatty acids are "essential" fats as our body needs but can't produce. [1] The recommended daily intake of omega-6 fatty acids ranges from 12 grams to 22 grams a day. [3]
