Introduction
There is an increase
of awareness in the role of omega-3 fatty acids. Omega-3 fatty acids
are found in fish and fish oils and aid in the prevention and management
of heart diseases. This can help reduce your risk of developing
an abnormal heartbeat; which can lead to heart problems and even sudden
death.
Greater
than half of all sudden death from cardiac causes have no history of cardiovascular
disease. In
fact, over 40% of all heart attack victim autopsies show clear coronary
vessels. Clearly, there is much more going on than the simple "cholesterol
kills" hypothesis. It is interesting to note that the
first
and most common sign of cardiovascular disease in post-menopausal women
is
death.
Yes, death.
In other words, there are no signs or symptoms.
 Omega-3
fatty acids provide a range of benefits and protection for the heart and
our body.
In addition
to reducing the risk of heart disease, they also help prevent blood clotting,
heart attacks and irregular heartbeats that could lead to sudden cardiac
death. They are anti-inflammatory, and inflammation is a key initiator of
the atherosclerotic cascade leading to plaque formation and sudden death.
Omega-3 also have anti-cancer functions as we shall see.
Omega-3
fatty acids can be divided into 3 main categories -- Eicosapentaenoic Acids
(EPA), Docosahexaenoic Acids (DHA) and Alpha-Linolenic Acids;
out
of which EPA and DHA have the most beneficial effects.
EPA and DHA
are found mainly in fish oils while Alpha-Linolenic Acids are usually derived
from plant sources such as soybeans, canola, walnut and flaxseed.
