Fish oil

Fish oil has been proved to lower cholesterol levels and helps prevent illnesses as diverse as attention deficit and Parkinson's disease.

Those who do not eat fatty fish are also more prone to Alzheimer's disease.

It is not just tasty, but very important for our overall well-being. Enjoying fresh salmon, mackerel and herring, for example, all of which contain high levels of the wonderful unsaturated fats EPA and DHA, is the way to get more fish oil.

They are called omega-3 essential fatty acids; there are actually three of them. ALA is the other one, from vegetable sources. You will get strange neurological diseases, lose your marbles and your hyperactive kids will drive you crazy if your family doesn't get fish oil from their food; or from supplements.

Fish oil supplements have been highly controversial over the years. First there were definite pointers to lose cardiovascular disease and stroke, and then when better research was done there appeared to be little benefit. In 2019 the Reduce-it trial found there were definite reduction in all-cause mortality from taking high doses of just one of the three omega-3 fatty acids, namely pure EPA; but primarily in Americans[3].

In short taking fish oil as a supplement remains controversial and the last word has certainly not been written. But all agree that salmon, herring and mackerel are highly beneficial. As Hippocrates said, let your food be your medicine.

Fat gets a lot of bad press, but we cannot live without it. Many neurotransmitters in the body, the nerves and brain itself demand them from our food.

But many folk still believe that, because they are obese, that fat must be the villain. It may be part of the problem, but too many carbs with a high glycemic index are more likely to be the cause of their weight problem.

Salmon has high fish oil content.

But it's the saturated fats that we need to keep an eye on, but even that's not simple. For reasons that I won't go into here, it is my opinion that butter (a saturated fat), is healthier than margarine (an unsaturated fat).

A report in the Archives of Neurology found that both people who consume a lot of saturated fat (that's butter, milk, cheese, eggs) and trans fatty acids (that's margarine) were twice as likely to develop Alzheimer's as people who avoid those fats in their diet.

Is fish oil harmful?

Is fish oil harmful ever? Yes, if it contains oxidised fatty acids, and that applies to many of the capsules of omega 3 that you may be buying. But it's almost impossible for you to tell unless you buy only from a reputable company.

So too, if it contains large amounts of mercury. You wouldn't know.

Also, if you have certain autoimmune diseases like sarcoidosis you should discuss taking fish oil with your doctor.

However, let's be honest. The risks of not getting sufficient omega-3 in your food are probably far greater than the small possibility that you may not be buying optimal fish oil.

So, do your homework. Scour the internet for the companies that produce the proven best fish oil, and don't go for that which is cheapest.

There are crooks in every corner these days, ready to sell you snake oil; if price is the only consideration, beware.

Fish oil

Fish oil promotes better general health including arthritis and dyslexia.

Total fat in the diet should be limited though. A diet that is unbalanced towards fats, whether saturated or not, is certainly unhealthy, causing obesity (of course) and an increase in bowel cancers and cardio-vascular disease.

But here comes the rub. Fats in the diet should also not be too low! There is very interesting research coming out now about the really serious neurological diseases like Motor Neuron Disease. Victims of this very serious disease have almost always been on a diet very high in carbohydrate, and simultaneously very low in fat.

I fancy I see you throwing up your hands in horror. Well, what must you do? Lots of fat, or minimal fat?!!! Really, it's very complex, and we still haven't all the answers. My advice is, keep the balance in your diet. No stringent limiting of fats, even if you are really overweight, but stick to those that are known to be healty.

Tingling in arms and legs is a sure sign of a neurological system under stress.

The benefits Omega 3 fish oil in salmon is that they keep the blood vessels clean and the fats in the blood in solution, maintaining healthy artery walls. It prevents the fatty plague that does such damage to the walls of your arteries. There are two essential omega-3 fatty acids in fish oil: DHA and EPA.

Are there side effects fish oil? Not that we know of, if it's indeed fresh and free from oxidized fish oil.

How much fish oil you should be taking is something of a vexed question. Rather too much than too little ... HOW MUCH FISH OIL ...?

But definitely not more than three 1000 mg capsules per day. It is increases bleeding and the threat of haemorrhagic stroke.

Hyaline cartilage

Hyaline cartilage is a vital subject for chiropractors; it's at the heart of the joint and vitally dependent on the omega-3 in fish oil. The alternative is premature arthritis.

Fish is also good for keeping the joints greased. Granny wasn't quite so stupid as we thought with her insistence on cod liver oil.

The  connection between fish oil  and children's behaviour is now very well established. It is important for the joints and arthritis, hence our interest in chiropractic in promoting more salmon, sardine and herring, for example.

We now know that omega 3 fish oil is important for the healing and restoration of hyaline cartilage in joints after injury and surgery; even after a slipped disk for example. HYALINE CARTILAGE ...

For strong bones, this best calcium for osteoporosis is worth a read; don't wait for the first fracture; then it is already too late.


New research shows that the vitamin D in fish oil has benefits not only for the arthritis in your bones, but critically also in the prevention of diabetes and metabolic syndrome, the underlying cause of heart disease. HIP PAIN and Vitamin D ...

it's vital for the prevention of arthritis of our joints and general health that we either eat fatty fish twice a week, or take fish oil capsules, or both; it raises the omega-3.

Anti inflammatory chili too has an important roll to play in the management of red hot joints.

Brain and nerve tissue

Brain synapses need the fatty acids best found in fish oil.

EPA and DHA, those two essential fatty acids in fatty fish, play an essential part in the development of the brain. Moreover, because of the part they play in neurotransmitters which carry the information from the 'dendrite' of one nerve to the 'axon' of the next nerve, they have been shown to help with memory and concentration.

Say from the researchers from the Dept of Psychiatry, University of Pittsburg: "Existing evidence links greater dietary intake of fish and Omega-3 to better early brain development and lowered risk of cognitive disorders in late life. Higher DHA (an Omega-3) was related to better performance on tests of nonverbal reasoning and mental flexibility, working memory, and vocabulary."

So, get out to the Fishmonger, and let's eat more fatty fish. Better and cheaper than taking salmon oil capsules, but they too do have a place in your pill box.

More fish and fowl, less red meat. One simple and delicious way to enjoy more omega-3 is by making a simple fish soup.

It's all a question of balance. If you are eating large quantities of fruit, salad and veggies, then within reason, you can enjoy your proteins and fats. But do stay away from margarines with their transfats, and eat butter only in moderation.

Do get your blood profile checked. Should you suffer from Hypercholesterolemia, a rare blood disorder, then even a healthy diet won't keep your cholesterol within normal limits. Better to be sure if you have a family history of heart disease.

Mother's Milk

It may come as a surprise, but mother's milk is very high in fat, nearly a half of which is saturated, considerably higher than most cow's milk, which has more protein. The reason is simple: it's the human infant brain that grows so fast in comparison with the calf's body . Brain tissue is make up largely of fat, and it's important that the developing brain be fed adequate fat.

If you want a baby with a big brain, feed it mother's milk. If you want a baby with a big body ... you get the drift. Large surveys have clearly shown that breast fed babies have significantly higher IQs.

It is extremely important that the lacting mother does not go on a low fat diet, as this will impede the development of her baby's brain. This is not the time to go on extreme diet.

Two important fats, lauric and capric acid, in mother's milk have been found to have anti-microbial properties. This can be boosted by drinking coconut oil which is rich in fat.

To summarise, eating more deep water fish that are rich in Omega-3 fish-oil helps brain development and gives protection against infections. Fish-oil for children, butternut soup for children, in the beginning via mother's milk, and then simply by eating salmon and the heathy fish bouillon that we rave about at Chiropractic Help is the way to go. And of course delic butternut soup, rich in Omega-3.

Too much fat in a meal is a common cause of indigestion heartburn ...

One simple remedy, should you know you are cooking up a fish-oil storm, is to include a generous portion of OLIVE GARDEN SALAD RECIPE (Greek salad.)

Attention Deficit Hyperactivity Disorder (ADHD)

Interesting research done in the United Kingdom with children with behavioural problems has shown that a mixture of fish-oil and Evening Primrose Oil has amazing benefits for children suffering from ADHD and dyslexia. Fresh fish-oil for kids is vital.

A bit of Chemistry

Omega 3

(a PUFA - poly unsaturated fatty acids)

Omega-3 is a PUFA; a poly unsaturated fatty acid.

There are three important "essential" omega 3 fatty acids that you can only obtain by eating foods rich in them; like fish oil. They are "essential"; without them growth will be stunted.

  1. Alpha-linolenic acid (ALA) (good stuff, found in seeds and nuts,  but not proven to reduce heart disease like EPA and DHA do).
  2. Eicosa pentaenoic acid (EPA)
  3. Docosa hexaenoic acid (DHA)

Forget the long names, but start looking for foods rich in ALA, and particularly EPA and DHA.

It's these latter two, EPA and DHA, that have been scientifically proven to reduce heart disease, blood vessel inflammation and lower blood pressure; memory and behavioural problems and attention deficit in children benefit too, and depression.

Omega-3 is also recommended by the American macular degeneration foundation along with lutein and zeaxanthin for the prevention of MD and cataracts.

You can find more information at our zeaxanthin macular degenation page.

There is research showing that humans have some limited ability to convert ALA, the vegetarian's omega-3 fatty acid, to EPA and DHA. The rich sources are from flax seeds, walnuts and

It's now universally accepted that the oils from fruit is the best; one example is "avocado fat." Type the words into Site Search.

Sorry, this stuff is complex, but you'll keep bumping up against these terms, and if you are interested, you will need to understand them.

You'll begin to understand why food scientists are now recommending we eat from as wide a selection as possible, to get all these nutritional substances in the body. Taking pills is not the same. If you have the purslane plant in your garden remember it is the richest source from green leaves.


Linolenic and linoleic acids are both PUFAs; watch it, they're not the same.

LinoLENIC acid comes in two forms, one is an Omega-3, the other an Omega-6 fatty acid:

  1. Alpha-linolenic acid. (ALA) Yes, that's the Omega-3 above, found richly in flaxseed. 
  2. Gamma-linolenic acid. That's the Omega-6.

LinoLEIC acid is another Omega-6 poly unsaturated fatty acid (PUFA)

All three are "essential;" unless you get them in your diet you will get neurological and other diseases. So will your children.

Omega-6 / 3 balance

The omega-6 /3 balance is vitally important in preventing inflammation in the diet.

Now the important bit: People who eat a diet with a ratio of Omega-6 to 3 as close to 1 as possible (equal quantities) are the ones who have the least inflammation in their bodies.

But the Western diet is hopelessly overbalanced in favour of Omega-6 from vegetable oils like sunflower oil with a ratio often of 30/1 and even higher.

Safflower oil remains controversial. It's high in omega-3 but highly processed, totally genetically modified, and containing a toxic substance.  Google it; the scientific community is divided on its health benefits. 

Both Omega-6 and 3 are "essential;" you can't live without them, but get the Omega-6/Omega-3 ratio out of sinc, and the rate of cancer soars, especially breast and prostate cancer; so does arthritis.

Ways to cook salmon and mackerel

There are of course many ways to cook salmon and mackerel; both are found in cold water, and are very rich in omega-3 fish oil; it's all about food and inflammation.

People will argue until the cows come home as to whether you should eat more fatty fish, or take the soft gel capsules. Probably, in my opinion, it's best to do both. Provided you can get high quality salmon oil that's not oxidised (like many are, buyer beware).

Smoked mackerel recipes is the whole mackerel. Head, bones, skin, fins, absolutely delicious, and the cheapest fatty fish. Just peels right of the bone. And you can certainly taste the fish. Yum! You'll also be able to feel the difference in any varicose veins in legs.


Your weight; are you worried about too much fat?

Concerned about your weight, with these recommendations about fatty fish? Yes, it's complex. But cutting out all the fat in your diet is extremely unhealthy. Your brain, memory, and nerves will all suffer; and joints too.

Eat the recommended amounts of the healthy fats, and keep the butter, margarine and animal lard to a minimum. Don't forget the olive oil benefits too; you can be generous with them. Every tablespoon per day extra means 10% less cardiovascular disease. 

Why margarine? All the adverts claim it's heart-friendly. Maybe, but it's not nerve-friendly because it's one of the "hydrogenated foods".

There is no doubt concerning the benefit of fatty fish; salmon, mackerel and herring, for example. But some research continues to cast aspersions on taking the oil in capsules, quite apart from the oxidation and mercury issues.

Amongst the strongest research is a meta-analysis; a pooling together of numerous trials.

In a recent analysis of 20 different studies, researchers report in JAMA, after evaluating the results of nearly 70,000 people, that there was no significant benefit on the incidence of heart attack, stroke and sudden death, when compared to a placebo by taking fish oil in capsules.

As always, eating whole foods for their nutrients is far more beneficial than swallowing pills containing the vitamins, minerals and fatty acids in that fish, for example. Oranges are better than OJ and freshly ground flax-seed is superior to the oil.

Enjoying cold water fish is not only tastier and cheaper but more beneficial that the oil capsules.

Pickling olives is so easy if you buy a large tin; then you have all the complementary anti-inflammatory effects of these olive oil benefits.
