Omega 3s have numerous health benefits
most notably in the prevention of cardiovascular disease by lowering triglycerides, regulating cholesterol, lowering blood pressure and preventing the build of atherosclerotic plaques. There is also evidence that omega 3s can combat mental disorders and their progression, reduce inflammation, reduce the risk of autoimmune conditions, and are also associated with lowered cancer risks.
It's not only important to incorporate good sources of omega-3 and omega-6s in your diet, but to also consume them in the proper ratio. Omega-6 fatty acids compete with omega-3s and can inhibit their effect. Ideally the ratio of omega-6 to omega-3 should be around 2:1, but the typical Western diet represents a ratio of closer to 16:1 due to a reliance on processed foods and oils. This imbalance is believed to be responsible for a number of inflammatory diseases such as heart disease and type 2 diabetes. Recent studies also show that a high omega-6 to omega-3 ratio plays a key role in the development of obesity.
