Omega 3 Fish Oils: Their Effect On Our Heart Health
by: Marcus Ryan  
If you're interested in your heart health, then this article will interest you.

Omega 3 fatty acids have made into the medical journals because of several important
and impressive health effects.

These omega 3 fish oils are available from natural food sources or as supplements (as
fish oil capsules). Either way, they can be used to help keep us healthy in mind and

It is a real medical discovery that has both the medical community as well as the general
population take notice.

In this article, we'll look at the benefits of omega 3 oils on heart health.

Benefits of omega 3 fatty acids in survivors of heart attacks (myocardial infarction)

The DART study (which stands for the Diet And Reinfarction Trial) showed that
survivors of heart attacks who took oily fish, equivalent to about 500 to 800 mg of
omega 3 fatty acids per day, had a reduction in total death rate of 29%. Those patients
who chose to take fish oil capsules containing 450 mg of omega 3 fatty acids (DHA and
EPA) per day, had a reduction in cardiac related death of 62%, and a reduction in risk of
death of 56%.

Then came the GISSI prevention trial, which was a large Italian study of 11,324
myocardial infarction survivors.

This study showed that myocardial infarction survivors who took a capsule of fish oil
every day, equivalent to 1 gram of fish oil, which is equivalent to 850mg of omega 3s,
had a 30% fall in cardiac mortality, and 45% fall in risk of sudden death. And these
benefits were apparent within just four months of the trial.

Then the Lyon study came into the picture, looking at 600 myocardial infarction patients.

It was found that those who took the advice of eating a Mediterranean diet, with an
emphasis on fruit and vegetables, and in particular an adequate intake of non marine
sources of omega 3 oils (alpha-linolenic acid), had a fall in their risk of heart related
death at 5 years by 70%, when compared to those patients who had no such dietary

Now let's have a look at fish oil effects in prevention of heart disease in the first place...

Benefits of omega 3 in preventing heart disease and sudden death in healthy individuals

Firstly, there was a study looking at the benefits of omega 3 fatty acids in healthy male
doctors. This study was known as the Physician's Health Study.

This study found that those with the highest levels of omega 3 fatty acids in their blood
streams, had a risk of sudden death that was only 1/5 of the risk of sudden death found
in the group with the lowest omega 3 fatty acid levels. That is, their relative risk was
19%. Those with the second highest levels of omega 3 fatty acids had a relative risk of
less than 1/3, with a relative risk of 28%.

Secondly, there was the Chicago Physician's Health Study Western Electric Study which
studied a group of 1822 men over a period of 30 years.

This study found that those who ate more than 35 g of fish per day had 38% less risk of
dying from heart disease, and a 44% reduction in risk of heart attacks, when compared
to those who had no fish intake.

These are just sample of the various studies on the health effects of omega 3 fatty acids
on cardiac health.

It is very sobering to realise that about 50% of heart attacks have no warning.

The benefits as shown in the studies above, relate to preventing heart attacks in those
who have already had one, as well as reducing the risk of myocardial infarction and
sudden death in healthy individuals.

The these essential fatty acids have been linked to reductions in risk of dementia and
depression, in the treatment of depressed patients, and improvement in IQ of children.

There are even studies on the effect of fish oils on reducing levels of aggression in young

The health benefits of omega 3 fish oils are certainly very interesting, and very

They vary from heart health, to mental health.

If you have a medical condition, you should always seek the advice of your doctor
before taking any new supplements or medications in case you are on medications or
have medical conditions that contraindicate the use of natural supplements.

Remember that prevention is always better than cure.

And that health is really our greatest asset.

So be alert for more developments in this area, including more medical studies on the
various health benefits of omega 3 fatty acids.
