omegaOmega-3 has long been recognized as the substance that can reduce the risk of heart disease. Those who are worried about their hearts, whether they want to avoid or improve their prognoses, can benefit greatly from eating several servings of fish each week. It reduces their risk of heart attack by over a third. Many people are worried that certain contaminants in fish might outweigh its advantages. However, in many cases especially pertaining to the heart, the benefits that can be derived far outweigh its potential disadvantages.

What is Unsaturated Fat?

In order to understand how omega-3 works, it is first important to determine what it really is. Fish contain unsaturated fat. But the main nutrient that can improve the heart is the omega-3 fatty acid. It is the type of unsaturated fat that reduces overall inflammation in the body.

Some also believe that omega-3 can lower blood pressure, decrease blood clotting, improve a child’s learning ability, and enhance the immune function among others. By consuming two servings of fish a week, a person reduces his risk of cardiac death.

What Types of Fish Should be Eaten?

Salmon, herring, and tuna are fish rich in omega-3 fatty acid. Thus, people who eat these types of fish will benefit the most. It is important to take note, though, that various types of seafood also contain small amounts of this nutrient. Generally, freshwater fish have less omega-3 acid compared to fish from the sea.

However, while most types of fish are beneficial, it is also important to take note that certain fish, such as catfish and tilapia, contain high levels of arachidonic acid, which is also found in egg yolk and red meat. While it is not harmful in itself, eating high levels of arachidonic acid can increase a person’s risk of heart disease because it causes inflammation.

  2. What do you think about getting your Omega-3 from other sources as well, such as nuts and seeds?

    I do agree with your post, oil coming from fish is a good form of oil; like HDL, it helps to remove cholesterol that causes coronary artery disease (CAD)from arteries.

    Good info. I love fish and seafood in general. Substituting fish for red meat will do a world of good for many folks. We should have 3 or 4 Fridays a week!

    Eating fish is a great way to get omega-3 fatty acid but a lot of people don’t like the taste of seafood. Luckily there are plenty of supplements available these days.

    Tilapia has more omega-6 than omega-3. So if you mistakenly eat tilapia thinking that you are getting omega-3, that is not the case.

    Are these the only fish that can be eaten where this benefit will be present…of all the cold water fish of the world these are the only ones?
