Omega-6 and omega-3 are essential fatty acids required by the body for controlling inflammation, brain development, and regulating blood pressure. Omega-6 is believed to have a pro-inflammatory role in the body, while omega-3 is believed to have an anti-inflammatory role. The ideal ratio between omega-6 and omega-3 is considered to be around 2:1. However, the typical Western diet, which is rich in processed foods and omega-6 processed vegetable oils, often leads to a ratio of over 10:1 in many people.
