Omega Oils 

Introduction

Omega-3 fatty acids (omega-3s) are a group of polyunsaturated fatty acids that are important for a number of functions in the body. Some types of omega-3s are found in foods such as fatty fish and shellfish. Another type is found in some vegetable oils. Omega-3s are also available as dietary supplements. 

About Omega-3 Fatty Acids

The three principal omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The main sources of ALA in the U.S. diet are vegetable oils, particularly canola and soybean oils; flaxseed oil is richer in ALA than soybean and canola oils but is not commonly consumed. ALA can be converted, usually in small amounts, into EPA and DHA in the body. EPA and DHA are found in seafood, including fatty fish (e.g., salmon, tuna, and trout) and shellfish (e.g., crab, mussels, and oysters).

Commonly used dietary supplements that contain omega-3s include fish oil (which provides EPA and DHA) and flaxseed oil (which provides ALA). Algae oils are a vegetarian source of DHA.

Omega-3 fatty acids are important for a number of bodily functions, including muscle activity, blood clotting, digestion, fertility, and cell division and growth. DHA is important for brain development and function. ALA is an “essential” fatty acid, meaning that people must obtain it from food or supplements because the human body cannot manufacture it.

Ácidos grasos omega-3

¿Qué son?

Los ácidos grasos Omega-3 son un tipo de grasa poliinsaturada (como los omega-6), considerados esenciales porque el cuerpo no puede producirlos. Por lo tanto, deben incorporarse a través de los alimentos, tales como el pescado, los frutos secos y los aceites vegetales como el aceite de canola y de girasol.
