While omega-3s have an anti-inflammatory effect, the omega-6 found in seed oils tend to be proinflammatory. Maintaining a healthy 3:1 ratio of omega-6 to omega-3 is important, as chronic low-grade inflammation is a hallmark of most chronic diseases, including obesity, diabetes and heart disease.
Omega-3 fats are essential polyunsaturated fats your body needs for a wide variety of functions, including proper cell division and function of cell receptors, muscle activity, cognition and heart health.
DHA is particularly important for your brain, as about 90% of your brain is made up of DHA, while EPA appears to be of particular importance for heart health.
Compared to placebo, people taking a daily supplement containing 1 gram of marine-based omega-3 and 2,000 IU’s of vitamin D for five years lowered their risk of heart attack by 28%.
People with the lowest sh intake had a 19% reduction in major cardiovascular events (the primary endpoint) and a 40% reduction in heart attacks (a secondary endpoint) when they supplemented with 1 gram of marine-based omega-3 and 2,000 IU’s of vitamin D.
