Omega 3
fatty acids are an important EFA or essential fatty acid that the body is
unable to make and must be obtained from a diet rich in foods that contain
these compounds.
Alpha linolenic acid (ALA) is the most important
member of the omega 3 family and more specifically can be used by your body to
make other omega 3 fats namely, eicosa pentaenoic
acid (EPA) and docosa hexaenoic acid
(DHA).
EPA and
DHA are vital for your brain function and development along with reducing blood
pressure, triglyceride levels (the fats and oils in your body) and maintaining
heart health.
Studies
have established that EPA and DHA also aid in the health of your eyes by
playing a protective role in the retina and protecting against eye diseases
such as macular degeneration. Couple this with the known anti-inflammatory
effects of a diet rich in omega 3 fatty acids, and you have benefits not only
to your eye health, but for many other vital functions also.
Other
benefits of EPA and DHA
-
improving your skin and hair;
- aiding
relief of arthritis symptoms and other joint problems;
- cell
renewal. Every living cell requires EFAs;
- aiding
depression, memory and cognitive thought;
-
reducing chronic inflammation.
How to
get more Omega 3 in your diet?
EPA and
DHA are mainly found in oily fish and fish oil, along with canola, walnut and
flaxseed oils. Larger fish such as salmon, herring, tuna and trout are all good
sources of omega 3.
ALA, of
which EPA & DHA are made from, is also found in nuts, seeds, green leafy
vegetables and soy beans.
Fish Oil
Benefits
As
mentioned, fish oils are a great source of omega 3 for improving heart health,
lowering cholesterol and fighting inflammation. The fattier the fish the
better.
Oils
ain't Oils...
There is
a booming market for fish oil supplements so it pays to do your research and
shop around.
The
number one rule is to buy high-quality oil that has not been processed or
refined at high temperatures, as heat destroys EFAs and can contaminate the oil
through oxidation damage.
Check
with the manufacturer about their refining and distillation processes for
production.
Generally
speaking, molecular distillation, which uses minimal heat and carefully removes
many contaminates, including mercury, is the best process for producing
high-grade fish oil. The disadvantage here is that it makes the supplement more
costly but... you get what you pay for.
Why not just
eat more fish?
To save
yourself the cost of expensive supplements why not just eat more fresh fish!
4 ounces
of Salmon contains approximately 1000- 4600 mg of omega 3 fatty acids. Conversely, other types of less
fatty fish such as cod contain 300 mg or less. Contrary to popular myth, the
body really does need plentiful sources of 'good fats', the mono and
polyunsaturated kinds.
Much
anecdotal evidence points to fish oils and omega 3 as being very beneficial for
dry eye symptoms if eaten regularly. Just be certain that, if boosting your
diet with supplements that the product is of good quality, otherwise it can
simply be money wasted.
I like to
buy a nice fresh piece (or two) of fish every week so that I don't need to buy
omega 3 supplements at all. However, sometimes a supplement is best when you
are time-pressed or maybe watching the budget!
