The benefits of flaxseed oil and essential fatty acids
With good reason, North Americans today are concerned about
obesity and weight control, which is often linked to increased risk
for cardiovascular disease and adult onset diabetes. We’ve heard so
much about maintaining a low-fat diet but difficult decisions face
us daily.
- Should we cut out all fats entirely?
- Should we continue to use butter and hydrogenated margarine,
or
- try the healthier trend of olive or flax oil?
- Which is best for us?
Fats have gotten a bad reputation. The truth is that we not only
like the taste of fat, but humans need certain types of dietary fat.
EFAs (essentials fatty acids) are the main structural component of
every cell membrane, and every cell requires them for healthy cell
growth and division. EFAs restore energy, help us digest our foods,
transport nutrients throughout the cells, and contribute toward
healthy hormone balance. Our challenge is to discern the difference
between ‘good’ and ‘bad’ fats.
Know your fats!
According to the Mayo Clinic, saturated fats that come from
animal products such as red meat, poultry, and whole milk, as well
as tropical oils, may be considered ‘bad’ fats. These saturated fats
can increase your blood cholesterol levels and put you at risk for
coronary artery disease. If you’ve ever looked at the waxy, greasy
pool of fat that remains after cooking red meat, it’s easy to see
and imagine the type of damage that solid (saturated) fats can do to
the human body.
Along with saturated fat, trans fat may raise your blood
cholesterol levels and increase your risk of heart disease. Trans
fat comes from hydrogenated vegetable oils, which are oils that are
manufactured through a process called hydrogenation. These fats are
commonly found in processed foods like cakes, cookies and
crackers—as well as fried foods such as doughnuts and the ever
familiar french fries. Oh, how we try to avoid them!
Other vegetable oils, such as flaxseed, safflower, corn,
sunflower, soy and cottonseed oils are considered polyunsaturated
fats. These types of fat usually remain liquid at room temperature
and can be healthy in helping to lower blood cholesterol levels. In
this group, one type of polyunsaturated fat—called ‘omega-3 fatty
acids’—may be especially beneficial to good health. Flaxseed is a
good source of omega-3s. “Omega-3 fat appears to decrease your risk
of heart attack, protect against irregular heartbeats and lower
blood pressure levels. It may even protect against some cancers,”
states the Mayo Clinic.1
We’ve known for some time now about the rich source of omega-3
fatty acids found in cold-water fish such as salmon, mackerel and
herring. However, excessive fish consumption is a concern for many
today, especially if you live near polluted waters where the fish
may be toxic with mercury. In recent years, increasing interest and
research of flaxseeds has shown that the essential oil found in
flaxseeds is rich in omega-3 fatty acids.
Finally, our last form of fat is known as monounsaturated fat,
which is found in olive and canola oils, as well as avocados and
most nuts. Along with polyunsaturated fats, monounsaturated fats are
also thought to contribute toward heart health by lowering
cholesterol levels and reducing the fatty deposits that may develop
in the arteries. Perhaps this is the reason that many popular
restaurants today are now serving olive oil as a topping for bread
instead of hydrogenated margarine.
Why are omega fatty acids so important?
“Essential fatty acids (EFAs) are incorporated into the membranes
of our body cells to keep them fluid. As a result, they act as
‘gate-keepers’ to allow the entry into cells of important nutrients
as well as the removal of toxins. More importantly, EFAs are
converted to hormone like substances known as eicosanoids that
effect physiological functions such as cell growth and division,
platelet aggregation (blood clotting), inflammatory responses,
hemorrhage, vasoconstriction and vasodilation of blood vessels,
blood pressure, and immune function. The activity of the eicosanoids
impacts clinical conditions involved in cardiovascular health,
inflammatory disorders, immunity, and certain cancers.”2
Although still being studied, research has shown that omega-3
fatty acids:3
Decrease risk of sudden death and arrhythmia
- Decrease thrombosis (blood clot)
- Decrease triglyceride levels
- Decrease growth of atherosclerotic plaque
- Improve arterial health
- Lower blood pressure
Increasing the n-3 fatty acids through flaxseed supplementation
has shown anti-inflammatory properties4;
can protect the immune system and lower the incidence of
inflammatory and autoimmune diseases5;
and balance glucose levels. Flaxseed oil containing alpha-linolenic
acid (ALA) has also been studied for use inhibiting the growth of
cancerous tumors of the breast, colon, and pancreas.6
Flaxseed oil: the ‘new’ wonder of our modern age
Sometimes referred to as the new wonder of the modern age, the
health benefits of the flaxseed are enormous. Flaxseed oil is
typically low in saturated fat (9%), moderate in monounsaturated fat
(18%), and high in polyunsaturated ‘good’ fats (73%).
A 10 g serving of flaxseed oil delivers an average of 5 g of
alpha linolenic acid (ALA).7 Food
processing has depleted much of the ALA and omega-3 content from our
modern foods—so much so, that experts recommend supplementation
since many North Americans are seriously deficient in omega-3
content. We may have an abundance of omega-6 and omega-9 fatty acids
derived from unhealthy sources (hydrogenated vegetable oils). This
creates an imbalance of essential fats and may impair healthy cell
functioning. The AIMega formula, with omega-6 and 9 from healthy
sources can help to provide better balance of EFAs.
AIMega™ delivers a balance of EFAs
AIMega™ is an organic seed oil blend
that delivers healthful and essential omega-3 fatty acids from
flaxseed oil, plus omega-6 and omega-9 from healthy sources (sesame
seed oil, olive oil, and sunflower seed oil). With AIMega™, you’ll
receive a complete blend of EFAs—with a balanced ratio of omega-3,
6, and 9. AIMega™ is especially helpful for those who seek to
restore energy, maintain healthy triglyceride levels, maintain
healthy glucose levels, and improve overall immune system and
cardiovascular health. As an organic seed oil blend, AIMega™
provides an alternative to fish oil supplements. Each soft gel
capsule is enhanced with rosemary extract and medium chain
triglycerides for additional health benefit. Look for AIMega™ coming
soon!
