Both Omega-3 and Omega-6 are “essential fats”. In other words, our bodies cannot manufacture them and they are necessary for a healthy life. They both have health benefits when used in place of less healthy fats. Researchers are still debating how much of each type is necessary, but overall they recommend more Omega-3s and using Omega-6’s in place of saturated and trans fats.
Primarily found in seafood as well as nuts, leafy greens and seeds, Omega-3 fatty acids appear to reduce inflammation which is a major contributor to many chronic health problems such as cardiovascular disease, arthritis, inflammatory bowel disease, Alzheimer ’s disease and obesity.
Oily fish, such as tuna, salmon and sardines are some of the best sources of DHA and EPA Omega-3 fatty acids. Research has shown that people who eat higher amounts of fatty fish have lower rates of heart disease and stroke.(1, 2) DHA is also important for supporting brain and eye health. (3, 4)
Nuts and seeds like Walnuts, flax seeds and chia seeds, and some leafy greens, like kale and Brussel sprouts, are plant sources of Omega 3’s.
Omega – 6 fatty acids may also help reduce the risk of heart disease when used in place of saturated and trans fats, they lower bad cholesterol (LDL), are important for normal growth and development, assist in brain function, and help our nervous system function properly. (5)
Vegetable oils such as Canola Oil, Safflower Oil, Soybean Oil and Corn Oil all contain Omega-6 fatty acids.
Most Americans have no trouble getting enough of these fats, and many health professionals would argue that we eat too much. The bottom line is, when they are used in place of less healthy fats and in small amounts, these fats are an important part of the diet and have important health benefits.
