Omega-3 fatty acid
(Redirected from Eicosapentaenoic acid)
Omega-3 fatty acids are a type of polyunsaturated fat that is essential in the human diet. They play a crucial role in body function, including energy production and tissue growth.[1] Omega-3s are most commonly found in fish oil, but can also be sourced from certain plant and nut oils.
Overview[edit | edit source]
Omega-3 fatty acids are a type of essential fatty acid, meaning they cannot be produced by the body and must be obtained through the diet. There are three main types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is primarily found in plant oils, while EPA and DHA are most commonly found in fish and other seafood.[2]
Function[edit | edit source]
Omega-3 fatty acids play several important roles in the body. They are integral to cell membranes and affect the function of the cell receptors in these membranes. They also provide the starting point for making hormones that regulate blood clotting, contraction and relaxation of artery walls, and inflammation. Omega-3s also bind to receptors in cells that regulate genetic function.[3]
Health Benefits[edit | edit source]
Research has shown that omega-3 fatty acids can reduce inflammation, and may help lower risk of chronic diseases such as heart disease, cancer, and arthritis.[4] They are also essential for brain health, contributing to neurogenesis, neuroplasticity, and neuroprotection.[5]
Dietary Sources[edit | edit source]
Common dietary sources of omega-3 fatty acids include:
- Fish and other seafood, especially cold-water fatty fish like salmon, mackerel, tuna, herring, and sardines.
- Nuts and seeds, such as flaxseeds, chia seeds, and walnuts.
- Plant oils, like flaxseed oil, soybean oil, and canola oil.
Summary[edit | edit source]
Omega-3 fatty acid is a main component of fats used by the body for energy and tissue growth. Omega-3s are essential fatty acids in the human diet; they are found in fish oil and certain plant and nut oils.
