Camelina (wild
flax) oil
1. What is Camelina?
Why is it called wild flax?
Camelina (Camelina Sativa) - also
known as wild flax, German sesame, or Siberian oilseed
– is an ancient oleaginous (oil-bearing) plant from the
Cruciferae family, which has been domesticated
and extensively used in Europe for several thousand years.
The seed oil of Camelina
contains an exceptional amount - up to 45 per cent! -
of omega-3 fatty acids, as well
as a unique antioxidant complex making the oil very stable
and resistant to heat and rancidity.
Known as “wild flax” because it is commonly
found growing together with common flax (and also sometimes
referred to as “false flax” due to its visual similarity
with regular flax), Camelina, while supplying almost as
many omega-3 fatty acids as regular flax, is much more
stable than the latter, and also tastes much better.

2. What are omega-3
fatty acids?
Omega-3 fatty acids are long-chain polyunsaturated
fatty acids (18-22 carbon atoms in chain length) with
the first of double bonds beginning with the third carbon
atom. They are called “polyunsaturated” because their
molecules have two or more of the so-called "double
bonds” between carbon atoms. Their designation as “long-chain”
fatty acids has to do with the fact that they consist
of at least 18 carbon atoms.
The omega-3 family of fatty acids includes
alpha-linolenic acid (ALA, 18 carbon atoms, 3 double bonds),
eicosapentaenoic acid (EPA, 20 carbon atoms, 5 double
bonds), and docosahexaenoic acid (DHA, 22 carbon atoms,
6 double bonds). ALA is the “basic” omega-3 fatty acid,
from which EPA and DHA are made in the body through a
series of enzymatic reactions
Some fatty acids, including alpha-liniolenic
acid (ALA) from the omega-3 family, are so important for
health that they have been termed “essential
fatty acids” (EFA). The essentiality of these fatty
acids stems from the fact that our bodies need them to
perform vitally important functions,
but are unable to manufacture them. Therefore, we must
get them daily from outside sources (such as food or dietary
supplements). Otherwise, we risk developing an omega-3
fatty acid deficiency and putting our health in danger
of serious negative consequences.

3. What happened
with omega-3 fatty acids in our food supply? What health
benefits can be achieved through omega-3 supplementation?
Until recently, the human diet has provided
adequate amounts of omega-3s to satisfy our basic need
for them. However, the 20th century has witnessed an unprecedented
shift from traditional, natural foods supplying abundant
quantities of omega-3 fatty acids to processed, denatured
packaged foods which are characterized by an almost complete
absence of omega-3s. In its tireless attempts to extend
the shelf life of its offerings, the food processing industry
has all but squeezed these important nutrients out of
our food supply altogether.
As a result, omega-3 deficiencies have reached
health-threatening proportions. Many researchers link
these deficiencies to the current epidemic of degenerative
diseases, including heart disease, arthritis and other
inflammation-related diseases, and even cancer. Extensive
research, including many clinical studies, have confirmed
that the regular supplementation of the diet with omega-3
fatty acids may be helpful in preventing or reversing
numerous debilitating health problems. Here is a partial
list of the health benefits achievable by supplementing
one’s diet with omega-3 fatty acids:
- Reducing the overall level of inflammation
in the body, and the resulting healing or alleviation
of many inflammation-related conditions such as peptic
ulcers, gastritis, acid reflux, IBS, and ulcerative
colitis
- Lowering the risk of heart disease, including CHD
(coronary heart disease) and atherosclerosis
- Lowering the level of triglycerides (fats) in the
blood
- Lowering high blood pressure (alleviating hypertension)
- Reduction in heart irregularities, such as elevated
heartbeat rates and arrhythmias (disturbances of the
normal rhythm in the heart's beating)
- Alleviation of circulatory problems, including varicose
veins and Raynaud's disease
- Helping to alleviate mood disorders, such as depression
- Reducing aggression
- Helping patients with attention deficit/hyperactivity
disorder (ADHD), dyslexia and dyspraxia
- Helping to improve memory and learning skills, and
prevent Alzheimer's disease
- Prevention of allergies in children
- Improving the condition of those who suffer from inflammatory
skin disorders such as psoriasis and eczema
- Alleviating rheumatoid arthritis (RA), and other inflammatory
forms of arthritis, affecting, in particular, persons
with psoriasis and gout
- Improving the immune status
- Alleviating certain symptoms of PMS
- Improving vision by lowering the risk of age-related
macular degeneration - an eye condition which is the
leading cause of severe loss of vision in people over
50.

4. What are the
pros and cons of different available sources of omega-3
fatty acids?
There are two major known sources of omega-3
fatty acids: certain types of fish (and their tissue or
organ fat, also called fish oil or fish liver oil), and
a number of plant seeds and their oils (flax oil being
the best known one).
Fish and fish oils have an advantage of
containing the most nutritionally available variety of
omega-3s, eicosapentaenoic acid (EPA), which is converted
directly into PGE3 – the compound
responsible for most of the health benefits of omega-3
supplementation. However, you must be very careful when
choosing fish or fish by-products as a source of omega-3s.
First of all, it should be kept in mind that only the
fatty, cold water fish varieties, such as salmon, sardines,
and anchovies, are rich in omega-3s, whereas most other
fish species supply little or no omega-3s. Even with salmon,
you have to make sure that it is wild and not farm-raised,
because only the salmon caught in the wild has any appreciable
amounts of omega-3s, because it gets them from its natural
diet. Farm-raised salmon does not supply any omega-3 fatty
acids.
Fish oils additionally suffer from contamination
with polychlorinated biphenyls (PCBs) and mercury. Modern
industrial agriculture produces a huge toxic runoff which
goes into our rivers and streams and eventually ends up
in the ocean. At the same time, coal-burning power plants
are increasingly polluting our atmosphere with mercury.
These harmful chemicals tend to accumulate in fish. The
larger the fish – the more PCBs, mercury, and other toxins
(like lead and cadmium) will be found in its tissues.
The problem is so serious that the US government has recently
issued a number of warnings cautioning pregnant women
and young children against consuming certain species of
fish because of contamination.
One more disadvantage of fish-derived omega-3
supplements is that many people, including an ever-growing
number of vegetarians, are simply not able to use them,
because they are excluding all animal products and by-products
from their diets altogether. For them, the only viable
alternative source of omega-3 fatty acids has been flax
oil.
While being the richest available plant
source of omega-3 fatty acids, flax oil has a serious
downside. It has to do with its susceptibility to oxidation
and rancidity.
The oil is poor in natural antioxidants,
and starts going rancid as soon as it is pressed from
the seeds. In spite of many precautions taken by the flax
oil industry, most commercially available varieties of
flax oil, both in liquid and in capsule form, get rancid.
And even if they don’t, there is no way to avoid oxidation
and rancidity once the oil enters your body. Once ingested,
it inevitably triggers free radical chain reactions, damaging
millions upon millions of healthy molecules. Your body
tries to stop these reactions with its own natural reserves
of antioxidants, such as vitamin E, putting these reserves
under an unnecessary and undesirable stress. As a result,
the benefits of taking flax oil may well be outweighed
by the harm done by free radicals and other toxic by-products
of lipid oxidation.
Considering the above, one inevitably comes
to a conclusion that, until now, none of the widely available
sources of omega-3 fatty acids have been fully satisfactory
and completely problem-free. While it is possible to achieve
the required level of omega-3 supplementation using either
fish and fish-derived products, or flax oil, it would
be highly desirable to have an omega-3-rich oil that would
also be more resistant to oxidation and free of toxic
contaminants. The good news is that such an oil does,
indeed, exist. This is the oil of Camelina
(wild flax).
Camelina seeds produce a golden-colored
oil with a delicate, almond-like flavor, containing up
to 45 per cent of omega-3 alpha-linolenic acid (ALA).
In addition to valuable omega-3s, it is uniquely rich
in powerful antioxidants, primarily tocopherols. At 110
mg/100 g, its vitamin E (tocopherol) content is among
the highest of all natural tocopherol sources. By contrast,
flax oil contains only trace amounts of vitamin E.
The fatty acid composition of Camelina oil
is also unique and very beneficial in terms of its health-promoting
qualities. In addition to being a rich source of ALA,
the oil is highly monounsaturated, naturally supplying
more than 30 percent of stable monounsaturated (oleic
and gadoleic) fatty acids. This significant proportion
of monounsaturates (monounsaturated olive oil forms the
basis of the healthy Mediterranean diet) further enhances
the oxidative stability of Camelina oil, and makes it
a more versatile cooking
oil.
The combination of these important
advantages makes Camelina oil the most balanced and desirable
source of omega-3 fatty acid supplementation. While providing
almost as many omega-3s as flax oil, it is highly stable
and abundant in vitamin E and other natural antioxidants,
as well as beneficial monounsaturated fatty acids. As
a result, it does not promote the formation of harmful
free radicals. On the contrary, it helps resist their
destructive effects by providing powerful antioxidant
protection.
