Why I'm interested in this
You know I'm a 50-something runner, cyclist and vegetarian.
I like to stay in good shape - both physically and mentally - I need to
do this for my own sake and, most importantly, for my family. A few years
ago I pulled myself back from the edge just in time, and I can tell you it's
been incredibly rewarding.
Although I take care of myself and like to think I'm eating the
right things, perhaps it is a little bit of a gamble. You see, while I
make sure I eat a wide variety of food from vegetarian sources, I even eat some
fish but to be honest, I don't enjoy it or probably have enough. Also I
know that I put my body under some pressure, especially with running and I'm running Milton Keynes Marathon once again so it's important I have the
right foods to allow my body to repair itself and maintain my good health:
taking these supplements now could be good timing for me.
Why Cod Liver Oil?
Different sources of Cod Liver Oil might provide slightly
different ingredients, so for the benefit of this post I am concentrating on
Healthspan. Traditionally many people use it to maintain healthy joints;
Cod Liver Oil provides high levels of Omega 3 fatty acids as well as being a
rich source of Vitamins A and D. Having done a little research into this,
this is a particularly useful supplement as it contains:
- EPA (eicosapentaenoic acid) and DHA
(docasanexaenoic acid) which are both forms of Omega 3 fatty acids.
More on this below.
- Vitamin D - required for teeth, bones and a
protective effect. Potentially we can be deficient through a lack of
sunlight on our skin
- Vitamin A - often known for helping our eyes work
well in the dark but this essential vitamin has a wide range of
other functions. Unlike vitamin D, it's important to remember we
cannot produce Vitamin A and we rely on what we consume to provide
sufficient quantities.
- Vitamin E - useful for protecting your arteries
and helping on-going tissue repair
It could be argued the main benefits are derived from the Omega 3
fatty acids (EPA and DHA) are for my cardiovascular health, or at least that's
the main attraction for me. Studies and various articles have shown fatty
acids can reduce the risk of heart attacks. This
is particularly important as I'm uncertain if I consume sufficient
amounts to give me the confidence I'm having enough. I do have some in
the form of ground flaxseed as part of my breakfast but this is a relatively
low concentration.
There are articles around to suggest fatty acids reduce the risk
of asthma, some brain functions (memory and depression) and possible protection
against some cancers but these are not the drivers for me. As a runner I
know my knees and ankles take a pounding - a few days ago when I ran for a
little over 10 miles non-stop, that is over 15,000 steps of my full body weight
landing on one foot at a time, so I am wanting to help protect myself with
these vulnerable areas. Omega 3, some say, help the health of our joints
and some sufferers who have rheumatoid arthritis might benefit too.
Although my legs were a little achy after that run, they were fine
for the next day's run so I must be doing something right!
Taking supplements
In my view, it is important to remember these are supplements. That is
supplements to our normal healthy diets and are helpful in filling gaps.
Even with the utmost care with our diets, Vitamin D can be hard to come
by especially in the winter months away from sunshine. Even with
Healthspan's 1000mg dose (which is a very sensible daily dose) the Cod Liver
Oil is contributing to the Recommended Daily Allowance of the Vitamins - it is
not a substitute for good healthy food or topping up our Vitamin D from natural
daylight.
The NHS has published a useful document on supplements (click
here) which helpfully keeps things in perspective. While it is a
complex area, in an ideal world we should be able to derive all we need from
our daily food.
I think of it as being like an insurance policy - a way of
managing some of those risks which are almost certainly there in the background
to some degree. How do I know if my fatty acid intake is enough?
Shall I wait until I get a heart attack to find out? Obviously the
answer is NO.
Another important consideration is recognising how medications can
inhibit the absorption of certain nutrients. Sounds crazy
doesn't it? It's true, you take a tablet for one thing and then it can
cause another problem somewhere else. I recently needed a course of
antibiotics but that's the first time for several years I have ever needed a
prescription at all. So if you take medication for depression, statins
for cholesterol, diabetes, pain relief, laxatives or tranquillizers ask
your Pharmacist about them inhibiting you getting all the goodness from
the foods you eat.
Dose. It is natural to think you can gobble up the things
that are good for you. Don't do that with any supplements. Period. Our bodies need a
gentle supply of nutrients, not blasting them with huge concentrated quantities
- exceeding the dose might do you more harm than good. Always it is
sensible for individuals to talk to their Doctors regarding supplements and
whether they should take them; in this case it is especially relevant for women
who are pregnant.
A word about Healthspan
I'm quite impressed by the Healthspan website in general and the
range of supplements they offer, with a good range of information there.
Sometimes in our family we think twice about mail order owing to
the hassle of going to the Post Office to collect packages that won't fit
through our letter box. Healthspan have been very thoughtful in the
design of their packaging. As you can see it is letter-box friendly and
arrived quickly.
Letter box friendly shape |
The packaging itself is cheery (I like that!) and well presented.
I like the "open book" design and the slim design, so it
doesn't take up much room in a kitchen cupboard.
There has been some general criticism of Cod Liver Oil supplements
around for a while, suggesting that they are not very pure, or they contain
levels of pollutants. It is therefore reassuring to read that they are
sourced from the clear, clean waters around Iceland
and the Government's tests have shown Healthspan's Cod Liver Oil to be the
purest available in the UK .
Sometimes people will quibble about the price. WAKE UP!
If you buy 240 of these, they work out at just £0.04 each. What
else can you buy for 4p that will be as healthy?
Wrapping up
As much as I might deny I am middle aged, I do need to take good
care of myself. I place real demands on my body through cycling and
running but these are GOOD demands. Each time I run for an hour or so, I
break down the bones and joints a little - as I sleep my body repairs itself
incredibly well and possibly even stronger - isn't that amazing? Because
of all this, it means getting the right nutrients is vital.
I think that because of the modern food production, we might not
always get the benefit we expect from our foods. That's one of the
reasons why we take the trouble to eat as much good quality, organic wholesome
fresh food as we can. No matter how keen we are to do this, our hectic
pressured lives mean we sometimes have to make compromises.
I sometimes think of myself in the future as being old, way into
the future. I imagine myself sitting in my rocking chair wearing my
carpet slippers and cardigan - I am fearful of having regrets where I could
have done something positive about. This includes taking on a few
challenges while I can - like Marathon
running. I know, plenty of 50 - 60 year-olds do this faster than me.
Little things like spending 4p a day on Cod Liver Oil could play a part
in making these things more possible and preventing illnesses and
diseases.

Hi, Doug Dont wish to stir up a wasps nest, but if you are vegetarian, cod liver oil is "fish". I use Linseeds/Flax instead, I am a bit of an extremist though, I enjoyed reading your articles on smoking, drinking and obesity, I wrote a paper on obesity 15 years ago now, not much change really!! Eat less, move more, relax!! (without legal/illegal drugs)
ReplyDeleteAll the best, Mark
Hi, Doug, I have about 2 tablespoons of linseeds a day, in food; eg porridge, homemade veggie burgers, quinoa etc. The problem with suppliments (capsules and tablets in particular) is they are "extra". People like you and me, who take reasonable steps to eat a balanced diet on a regular basis are probably over doing it.
ReplyDeleteMost people in the west get far too much omega 6 as it is, the ratio of 0mega 3 to 6 is important also. Obviously a capsule of fish oil a day is not going to hurt at all.
You and me are obviously similar in thought, which is rare for me.
Thanks again Doug.
