Essential Fatty
Acids
Why are they the "good" fats?
Well, they are not necessarily good, in fact.
There are several types of fatty acids and you need to understand
them, at least in outline, otherwise enthusiastic supplementation
will make your health worse. Here is a simple tutorial that
will clear away the confusion. It does away with the tendency
to explain it all in excruciating detail, so that it becomes
too much for the layman.
Start by dividing essential fatty acids (EFAs)
in your mind into 3 groups:
- the omega-3 fatty acids
- the omega-6 fatty acids and
- "the rest".
Then it gets easy because we can:
- drop "the rest" (omega-9s and stuff), you can
make special enquiries if you are interested.
- state that everyone is getting far far too much of the
omega-6 fatty acids and you should not supplement them at
all, unless you are already on a really tip top diet.
- Talk about urgent supplementation of omega-3s, which is
one of the biggest and most disastrous nutritional shortages
in our civilized world.
You see essential fatty acids are just what they
are named "essential" (don't worry about why they
are fats or why they are called acids). In a sense these fatty
acids are like vitamins; your body cannot make them but needs
them for optimal health. Lack of essential fatty acids, we now
know, can lead to premature ageing, cancer, arthritis and a
host of other ills. Fatty acids are essential for maintaining
healthy cell membranes and that means they have impact on all
aspects of our health. But probably the most important organ
is the brain, which is approximately 40% fats and needs to be
maintained properly.
A proper balance of fatty acids means the right
proportion of the group called omega-3s to the omega-6s (again
I think it sheds no light to explain why they are given these
labels, so I'll skip it). Suffice it to say that omega-6s are
very common and are present in excessive quantities in most
manufactured foods. They come from a variety of sources but
certainly grain seeds, which are used as wheat and corn flour
in literally hundreds of thousands of propriety food products.
The typical American diet feeds the individual an omega-6 to
omega-3 ratio of anything up to 50:1. It should be 1:1. Corn
oil, which gushes with omega-6 fatty acids, is one of the most
widely distributed food ingredients there is and its effect
is dire.
Why? you ask, when omega-6 I've already said is
essential. Because of the matter of balance. If you get too
much omega-6 then this squeezes the omega-3s, which then go
into a relative deficiency state. The consequences of low levels
of omega-3 fatty acids are very bad. They include at least the
following: hardening of the arteries, hypertension, increased
blood clotting (risk of heart attacks), diabetes, cancer, obesity,
arthritis and other degenerative diseases, premenstrual tension,
infertility and more. Doesn't this begin to sound like this
is a list of civilized society's diseases? Well it is! All because
we eat junk, loaded with omega-6 fatty acids and very low of
necessary omega-3s. Now you see why I tell you, whatever you
have read, to dump the omega-6 supplements right away. Omega-6
supplementation will make your health much worse until you have
corrected the chronic deficiency of omega-3s!
To avoid unnecessary omega-6s, you are advized
to avoid sunflower, corn, soy, safflower, canola, or products
that contain these oils. That means no hydrogenated or partially
hydrogenated fats, no margarine, no vegetable oil, no shortening.
These oils are chock full of omega-6 fats and will only worsen
your omega 6:omega 3 ratio.
It's blunt but easy to understand. The trouble
is there are many ignoramuses out there telling you different
and telling you you need omega-6s. Often these are the people
who are selling omega-6 products of course, like oil of evening
primrose, borage, star flower and the like. If you've tried
these oils and found your hair and nails became brittle and
poor, this imbalance of 6 to 3 is the reason; you made things
worse. There are many misguided products on the market which
attempt to address the problem comprehensively by combining
omega-3s with omega-6s in the same package. This still won't
work, because it does not address the all-important ratio of
6:3. These are OK for people who have been on the health kick
for years, have corrected their EFA imbalances and now require
to supplement both in the correct ratio (about 2:1 is the maximum,
twice as much 6 as 3). But everyone else needs to take omega-3
entirely alone (I'm not saying you don't need any omega-6s but
that you can get enough to be going on with from a good nutritious
diet, with healthy fresh food); I'm talking here about supplementing.
You need to aim at an intake ratio of about 1:1
for the first six months. The only way you are going to achieve
that is by taking lots of omega-3 only supplements. Where do
you get omega-3s? Well, that's part of the problem, because
they are not widespread in nature. The best source was fish
oils. You will read lots of good stories about the benefits
of fish and seafood, such as the eskimo diet. I am utterly convinced
by the scientific soundness of the findings that such a traditional
diet is enormously beneficial. The trouble today is that fish
is very polluted, with mercury, PCBs and other pesticides. It's
no longer a natural foodstuff. I'm not saying don't eat fish
- eat lots, it's good for you. But when it starts being processed,
which concentrates pollutants, then it can become dangerous.
Some health food manufacturers have had to be warned that their
EFA product contains illegal levels of DDT, DDE and so forth.
If you choose to take fish oil capsules make sure they are guaranteed
free of pollutants. Make sure they have balanced EPA and DHA:
take one capsule per 10 kilogrammes of body weight a day. That
could mean 8- 12 capsules for some people, which may be expensive.
That leaves us with vegetable sources. All plants
contain omega-6 and omega-3 fats. But some are noted for high
levels of one or the other. The best source of omega-3s in the
plant kingdom is the seed of the flax plant (flax seed, also
known as linseed). Take pure flax seed cold-pressed extract
in the same quantities you would a fish oil. Other sources of
omega-3s are: extra virgin olive oil, coconut oil (read more
about the health properties of coconut oil), avocados, and organic
butter, or better yet grass-fed organic butter.
But, surprise! The best possible source of omega-3
is beef! (information from a study at Iowa State University
in August 2001). Not the fatty stuff from your ordinary supermarket
meat counter, for sure. But grass-fed free-range beef is found
to have a 6:3 ratio of 0.1:1. Or to turn that around, free-range
beef has 10 times more omega-3 than it has omega-6, which is
ideal for correcting years of chronic deficiency. The cow is,
in effect, your supplement manufacturer: it gets the omega-3
from the grass! So get grinding that chuck steak and eat plenty
of burgers! Beware though: food suppliers always try to trick
you. They advertize "grass fed" beef which is not
what I am referring to. Of course ALL beef is grass fed - for
part of its life. But the ordinary commercial beef animals are
switched to grains for fattening up in the final months (you
know, the stuff the government lackey's keep insisting is what
we need to eat for optimum health. Now obesity is the "norm").
Eating this grain-fed beef will worsen your 6:3 ratio.
The only way you can be sure you are getting truly
grass-fed free-range meat is to have a guaranteed supply and
that means either an organic health food supplier you trust,
or phoning the farmer direct and asking the questions (assuming
you trust the answers you get).
Another good source of omega-3s, recently cited,
is cheese from the milk of alpine fed cows. A study from the
Department of Medicine, Kantonsspital Baden, and the Federal
Institute of Technology, Zürich, Switzerland studied 40
different cheese, using gas chromatography, and came to the
conclusion that omega-3s were four times higher than in other
cheeses. Emmental had 40% opf the grass-fed total and, suprisingly,
cheese from linseed-supplemented cattle had only 49% of the
healthy EFAs of the grass-fed types [High omega-3 fatty acid
content in alpine cheese: the basis for an alpine paradox. Hauswirth,
C. B., Scheeder, M. R. L., Beer, J. H., Circulation 2004 Jan
6;109(1):103-107]
Vegetarians and even more so vegans, of course,
must work extra hard to correct their 6:3 ratio.
EXTRA TIP:
Get cold pressed flax seed oil and use it for massage. Have
someone who cares about you give you a nice massage, using the
flax seed oil. It is readily absorbed through the skin! However
it will stain the sheets yellow; you need to take precautions
to prevent this. What a nice way to supplement!
You see, you didn't need to know all those horrible
names, like docosahexanoic acid and eicosapenta-thingummy, did
you? |
