1. omega-3

   Omega−3 fatty acids, also called Omega-3 oils, ω−3 fatty acids or n−3 fatty acids, are polyunsaturated fatty acids (PUFAs) characterized by the presence of a double bond, three atoms away from the terminal methyl group in their chemical structure. They are widely distributed in nature, being important constituents of animal lipid metabolism, and they play an important role in the human diet and in human physiology. The three types of omega−3 fatty acids involved in human physiology are α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). ALA can be found in plants, while DHA and EPA are found in algae and fish. Marine algae and phytoplankton are primary sources of omega−3 fatty acids. DHA and EPA accumulate in fish that eat these algae. Common sources of plant oils containing ALA include walnuts, edible seeds, and flaxseeds as well as hempseed oil, while sources of EPA and DHA include fish and fish oils, and algae oil. Mammals are unable to synthesize the essential omega−3 fatty acid ALA and can only obtain it through diet. However, they can use ALA, when available, to form EPA and DHA, by creating additional double bonds along its carbon chain (desaturation) and extending it (elongation). Namely, ALA (18 carbons and 3 double bonds) is used to make EPA (20 carbons and 5 double bonds), which is then used to make DHA (22 carbons and 6 double bonds). The ability to make the longer-chain omega−3 fatty acids from ALA may be impaired in aging. In foods exposed to air, unsaturated fatty acids are vulnerable to oxidation and rancidity.There is no high-quality evidence that dietary supplementation with omega−3 fatty acids reduces the risk of cancer or cardiovascular disease. Furthermore, fish oil supplement studies have failed to support claims of preventing heart attacks or strokes or any vascular disease outcomes.

1. omega-3

   Omega-3 refers to a type of polyunsaturated fatty acid that is essential for human health. They are considered "essential" because the body cannot produce them on its own, so they must be obtained through diet or supplementation. Omega-3 fatty acids are commonly found in fish, such as salmon and tuna, as well as in flaxseeds, chia seeds, and walnuts. They are known to play important roles in brain function, growth and development, inflammation, and heart health.

Examples of omega-3 in a Sentence

1. Brian Power:

   My advice is to get omega-3 [ fatty acids ] from eating fish at least twice a week as part of a balanced diet, even if you don't eat fish, you can get it from other sources such as nuts and seeds e.g. walnuts, soya products e.g. tofu ; and green leafy vegetables.

2. Erin Kenney:

   Salmon contains omega-3 fats which have been shown to significantly reduce the risk for sudden death caused by cardiac arrhythmias and all-cause mortality in patients with known coronary heart disease, these essential fats help by reducing inflammation in the body. If you don't like salmon, you may get the same benefits from a supplement based on a meta analysis that found fish oil omega‐3 supplements lowered risk for heart attack and death from coronary heart disease.

3. Rajani Katta:

   When I think about omega-3s, I think about them for their anti-inflammatory properties, it's important to have lots of omega-3 fatty acids in your diet.

4. Carmine Pariante:

   The omega-3 supplements only worked in children that had lower levels of EPA (eicosapentaenoic acid) in their blood, as if the intervention was replenishing a lack of this important nutrient.

5. Karen Costenbader:

   This is the first direct evidence in older adults that taking vitamin D or omega-3 fatty acids -- or a combination -- for five years reduces autoimmune disease incidence, with more pronounced effect after two years of supplementation.
