Some vegetable oils

Both omega-6 and omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are necessary for your body to function. Unfortunately, the ratio of omega-6 fats in modern diets is about 20:1, which is much more than what the body actually requires. This imbalance in the omega-6 to omega-3 ratio has been linked to systemic inflammation, and studies have revealed that it may increase the risk of disease.

Most people who eat a Western diet eat a diet high in fats containing omega-6s but don't get enough omega-3s. It is therefore advised to restrict your consumption of foods high in omega-6 fats. These consist of soybean oil; corn oil; sunflower oil; products made with these oils, including many processed, prepackaged foods; etc. Increasing your omega-3 intake is another option. Among the best sources of omega-3s are flaxseed oil; fatty fish, like salmon; walnuts; etc.
