Due to the vast amount of research documenting the benefits of omega-3 fatty acids, it becomes difficult to find the benefit of the omega-6s. However, they too have a vital role in our body, and we still need to meet our requirements through diet. The main role that omega-6 fatty acids seems to play in our bodies is in brain function, growth and overall development.
Much of the research done to determine the result of deficiency inadvertently also restricted omega-3 consumption. Thus, it remains unclear what the actual requirement and outcomes of Omega-6 deficiencies are. However, due to today's high consumption of vegetable oils, it is practically impossible to become deficient in omega-6 fatty acids.
