Omega-3 fats are a family of long-chain polyunsaturated fatty acids (aka PUFAs), which are distinguished from saturated and monounsaturated fatty acids .
because they contain two or more double carbon-carbon bonds within the fatty acid chain. There are three main types of omega-3s: ALA, DHA, and EPA.
Your body is able to make certain fats (lipids) from other fats, but omega-3s are essential fats that your body is unable to make (ALA) or very inefficient (EPA and DHA) at making itself
so you must consume them instead. Omega-3 fatty acids are important to heart, brain, joint, eye, and overall health—in other words, they're not worth skimping on or skipping
Omega-3s, particularly EPA and DHA, primarily come from fish with higher fat content. Unlike other in countries where fish is a main food staple, like Japan and Korea
Starting points are good places to begin, but the AHA goes on to recommend a higher marine omega-3 intake (1 gram and up of EPA and DHA daily)
These higher amounts of omega-3 fats optimally support your body's need for omega-3s, which are used for critical cell membrane functions.
