Learning about Omega-3 fatty acids, and why fish and seal oils are more important to our diet now than they were a century ago.
Take a stroll down any supermarket aisle and you will see plenty of evidence that there are “fatty acids” heralded as “essential” for good health. The amazing powers
Of the “Omega-3,” as they’re termed, are emblazoned in bright, bold letters on everything from milk cartons to yogurt containers to pet food boxes. Three decades ago, though, little was known about these nutrients that now enrich our manufactured food supply and are sold as supplements.
In the early 1970’s, scientists were determined to find out how the Inuit people of Greenland had evaded the cardiovascular problems that plagued the western world. Throughout the United States and Canada, many people were stricken with high blood pr4essure, blood clots and heart disease. Yet despite consuming a diet high in fat (mostly from fish and seal meat), the Greenland Inuit were relatively free of such afflictions. The key to their good health, scientists found, was in the effects of Omega-3 polyunsaturated fatty acids, which are highly concentrated in marine oils.
Since this discovery, the medical community has produced thousands of studies proving their health benefits. Perhaps not surprisingly, the research shows that with the modernization of society and our tendency to eat more processed foods, the rate of diet-related disease has risen in concert with these changes.
Striking a Balance
Part of the problem is that the modern diet has created an imbalance between two types of essential fatty acids. When our ancestors consumed natural foods, Omega-6 essential fatty acids (found in vegetable oils) and Omega-3 essential fatty acids were in near-perfect balance. Since we began relaying on processed foods, however, we’ve tipped the scales drastically in favour of the Omega-6 variety.
In his book: Omega-3: The Seal Connection, Dr. Cosmas Ho explains, “The relationship of equivalence between the two Omegas is critical because they self-check each other in a delicate balance to regulate thousands of metabolic functions.” A general practitioner in Newfoundland for more than 40 years, Dr. Ho has been studying Omega-3since the early 1990’s.
He says some experts suggest that modern food trends have most people consuming Omega-6 in volumes up to 30 times the amount of Omega-3, a problem that he and thousands of other medical professionals agree is responsible for a myriad of illnesses.
“Nearly every biologic function is somehow interconnected with the delicate balance of Omega-3 and Omega-6,” Dr. Ho writes. He also explains that this shift is harming our bodies’ control of inflammation, cardiovascular health allergic reactivity, immune responses, hormone modulation, IQ and even behaviour.
Take a look at the ailments contributed to by lack of sufficient Omega-3
The Omega-3’s include Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These act to reduce inflammation, lower the risk of blood clots, promote growth and development in infants, and d support brain functions. Another essential fatty acid, alpha linolenic acid (ALA – found in high doses in flaxseeds) can be converted to EPA and DHA once ingested. (Some medical professionals warn that this conversion is not a sufficient source of Omega-3. Read more on this below.)
The Best Food Sources of Omega-3
before purchasing products that claims to be “enriched with Omega-3.” Carefully read the label. If you’re interested in consuming EPA and DHA directly, make sure these acronyms are listed in the ingredients. Many products that are fortified with OPmega-3 list ALA as an ingredient, which, says, Dr. Ho, is not the most efficient way to reap their benefits.
In his book, he states that the bodies of elderly people and individuals who aren’t completely healthy have difficulty converting ALA to EPA and DHA. Furthermore, Dr. Ho states, an overabundance of Omega-6 (which most average people have) may inhibit the conversion.
He also warns that some companies vie for our money by claiming their products are not only a great source of Omega-3, but also of Omegas 6 and 9 – a 3-for-1 deal. Sounds great doesn’t it? But Dr. Ho says offering this is ridiculous, as the body produces Omega-9 on its own and it is well documented that we already consume far too much Omega-6.
Because the body cannot produce its own Omega-3, Dr. Ho says we must consciously choose foods (or take supplements) that will replenish our supply. Below are some of the main sources of Omega-3 fatty acids to consider implementing into your diet. Before changing your diet or taking supplements, however, seeks the advice of a medical professional to determine what sources and doses of Omega-3 are right for you.
Seeds and Nuts
Whether sprinkled on toast or taken as an oil supplement, many people consume flax in an effort to boost their daily Omega-3 intake. Flax is the common source of Omega-3 in many of the fortified products sold in supermarkets. Walnuts are also high in Omega-3. If you don’t fancy eating seeds or nuts daily, both also come in the form of oil, which can be used to make healthy salad dressings.
Both flax and walnuts contain ALA, the fatty acid our bodies must convert to DHA and EPA before we can reap the benefits. Many experts argue that consuming ALA in an inferior method of increasing our Omega-3 intake. “Humans may be unable to convert enough ALA to achieve optimum levels,” notes Dr. Ho.” Nonetheless, eating foods high in ALA is better than not receiving any Omega-3 fatty acids at all.”
Fish
Some of the best sources of essential fatty acids don’t come in brightly coloured packages with “Omega-3” stamped boldly on it. Instead, suggests Dr. Ho, they are found at the fish counter. With 2.5g of EPA and DHA per 100g serving, mackerel is one of the best fish sources of Omega-3. Salmon, herring, tuna and cod also pack a powerful punch. Health Canada recommends two Food Guide servings of fish each week. Krill, shrimp-like crustaceans near the bottom of the food chain, are another potent source of Omega-3.
Seal
When researchers traveled to Greenland to uncover the secret of the Inuit population’s lack of cardiovascular problems, their regular consumption of seal meat was found to be a major factor in their remarkable health. Seal meat contains 4.5g of EPA, DHA and DPA (another healthful Omega-3 fatty acid found in large quantities only in seal meat and human breast milk.)That’s nearly double the amount of Omega-3 contained in mackerel and other fish species. And Dr. Ho believes that seal meat and seal oil are superior sources of Omega-3 for other reasons.
“Fish are cold-water animals; seal is mammal – mankind are mammals,” said Dr. Ho during a recent interview with Downhome. He pointed out that like humans, seals filter out many natural impurities found in the fish they eat. “They digest it for us and manufacture it for us.” Dr. Ho also believes seal oil is a superior source of Omega-3 due to its lack of Omega-6, which most people need to reduce dramatically. There are trace amounts of Omega-6 in seal oil, but quantities are doubled, tripled or even quadrupled in flax and fish sources of Omega-3; definitely not an efficient way to restore balance, says Dr. Ho.
His company, Newfoundland Health Foods Corp, was the first to manufacture edible seal oil capsules. And Dr. Ho has been dubbed the “father of seal oil” for his belief in its benefits.

Seal Oil Study shows more benefits
by: Everton McLean
The Evening Telegram
Sunday, June 29, 2008
If you want a healthy dish, trim the fat off your beef, chicken or pork. But leave it on your seal meat.
Or just take a seal capsule instead.
That’s the message from a Memorial University researcher who has been studying the health properties of seal oil for the past three years.
Sukhinder Cheema, an associate professor of biochemistry, says the oil, which is derived from the mammal’s blubber, has far greater health benefits than some other supplements, such as fish oil.
First off, she said, it’s low in saturated fats.
“Saturated fat is bad for you. You go to the store and everything says ‘Low in saturated fats,’” she said. Seal oil is very low in saturated fats compared to fish oil.
“Secondly, we all say olive oil is very good for you because it is high in monounsaturated fats. Seal oil is high in this also.”
She said her research has also shown that the body can use seal oil more easily than fish oil, due to its composition. Seal oil even has an extra type of Omega-3 fatty acid compared to fish oil, Cheema said.
“Seal oil contains three Omega-3 fatty acids, while fish oil only has two.”
In addition to being useful in fighting heart disease by lowering lipid levels, Omega-3 is beneficial against Alzheimer’s disease, asthma and arthritis, Cheema said. It’s also good for the eyes, and because it things blood, it can b e used to reduce the risk of blood clots.
To cap it off, seal oil also has a better shelf life, she said.
“Seal oil is also more stable and less prone to oxidation, as opposed to fish oil.”
Cheema said the new information may be useful for companies in the province that make and sell the oil. Recently, St. John’s-based Company North Atlantic Biopharma started a partnership with Chinese companies to develop a seal oil alternative to soy products.
While she outlines its health benefits, Cheema said people who are thinking about using the seal oil should consult a physician first, due to its ability to inhibit blood clotting in large doses.

Omega-3 fatty acids are being increasingly promoted as important dietary components for health and disease prevention.1,2 These fatty acids are naturally enriched in fatty fish like salmon and tuna and in fish-oil supplements. An increasing number of foods that are not traditional sources of omega-3 fatty acids, such as dairy and bakery products, are now being fortified with small amounts of these fatty acids.2 This recent promotion of omega-3 fatty acids has likely been driven by recommendations for omega-3 fatty acid consumption made by scientific groups such as the American Heart Association.3 The search for the molecular and cellular mechanisms by which omega-3 fatty acids affect health and disease has led to a large body of evidence which suggests that these dietary lipids modulate numerous processes, including brain and visual development, inflammatory reactions, thrombosis and carcinogenesis. An obvious question that someone unfamiliar with omega-3 fatty acids might ask is: How can these nutrients affect so many seemingly unrelated processes in different cell types and tissues? The goal of this review is not to comment on the extent to which dietary omega-3 fatty acids affect health and disease, but rather it is to give an overview of the nature of these dietary components and to present some of the mechanisms by which they may modulate cellular functions.
What are omega-3 fatty acids?
Our diet contains a complex mixture of fats and oils whose basic structural components are fatty acids. We generally consume at least 20 different types of fatty acids, which are classified as saturated, monounsaturated and polyunsaturated. Fatty acids have many fates in the body, including β-oxidation for energy, storage in depot fat or incorporation into phospholipids, which form the major structural components of all cellular membranes.
Not all dietary fatty acids are created equally. Because humans do not have the enzymatic machinery required to synthesize omega-3 fatty acids, they must be obtained from the diet (termed "essential fatty acids"). Even among dietary polyunsaturated fatty acids, there are different families of compounds, and this is at the heart of the difference between omega-3 fatty acids and other dietary lipids. Omega-3 fatty acids generally account for a small fraction of the total daily consumption of fatty acids in Western societies.2,4 Fish such as tuna, trout and salmon are especially rich sources of these fatty acids. Fish-oil supplements are also a rich source, as they typically contain 30%–50% omega-3 fatty acids by weight. Small quantities of omega-3 fatty acids are naturally present in meats like beef, pork and poultry. Despite containing small quantities of omega-3 fatty acids, meats contribute to the overall intake of these fatty acids simply because of the large amounts consumed in Western societies.4
Omega-3 fatty acids from fish and fish oils are not to be confused with those from plant sources, such as flax and canola oil. These plant oils are enriched in an omega-3 fatty acid called -linolenic acid, which is a metabolic precursor of the omega-3 fatty acids found in fish and fish oils (Figure 1). Although we are able to convert dietary -linolenic acid into eicosapentaenoic, docosapentaenoic and docosahexaenoic acids (which are found in fish and fish oils), this conversion is not efficient in people who consume a typical Western diet. Consequently, following the consumption of foods containing -linolenic acid, our tissues are exposed to very little of the types of omega-3 fatty acids found in fish and fish oils. Some beneficial biological activity has been attributed to plant-derived omega-3 fatty acids; however, the associated health benefits are likely independent of the conversion of -linolenic acid to the fatty acids found in fish. In addition, dietary oils that are rich in -linolenic acid do not, for the most part, reproduce the biological activity associated with dietary fish oils.3 The balance of this review will address the types of omega-3 fatty acids typically found in fatty fish and fish-oil supplements.

Most Canadians not getting enough Omega 3's, from Dr. Cosmas Ho
2/19/04 - CTV News
CTV.ca News Staff
Recent studies suggest limiting the intake of some fish because of contaminants. But fish are a rich source of omega 3 fatty acids and many more studies suggest we are simply not getting enough.
Health groups have urged consumers to limit their intake of farmed salmon which can have high levels of PCBs, and limiting tuna and other fish because of mercury.
With the studies raising concerns about the man-made pollutants in our seas, some fish shop owners have watched sales slide by as much as 50 per cent.
And that worries some doctors who say their patients are not getting enough omega 3s -- essential fatty acids that some plants provide in small amounts, but are in rich supplies in fish.
Studies suggest those who don't get enough omega 3 fatty acids appear prone to a number of diseases.
"That includes certain forms of cancer, diabetes, arthritis, and other autoimmune disorders like lupus," says Dr. Peter Jones of McGill University.

Dr. Ho on Cardiovascular Disease and Omega 3
Omega 3 PUFAs and Cardiovascular Disease
As most of us are aware, in today’s society, our human diet is vastly different than that of our ancestors. In earlier times hunting, fishing and gathering of foods was an important part of their lifestyle. This resulted in them acquiring a balance of Omega 6 to Omega 3, a ratio of 1:1. Due to our fast lifestyle and the need for convenience we are now preparing and eating less and less fish and other marine mammals.
As a result, our diet is deficient in Omega 3 Long Chain Polyunsaturated Fatty Acids (PUFAs), showing a ratio of 25-35:1. Omega 3 is ‘essential’ for human health and development, meaning that it is necessary for life. This ‘essential’ fatty acid cannot be produced by the body, but must be obtained from another food source such as fish, marine mammals, or Seal Oil capsules. The Omega 3 Seal Oil (PUFAs), which I have developed, is composed of Eicosapentaenoic Acid (EPA, 20:5n-3), Docosahexaenoic Acid (DHA, 22:6n-3), and Docosapentaenoic Acid (DPA, 22:5n-3).
In recent research all three of these components have been proven to be vitally important in human health, growth and development, from infancy to senior years. Omega 3 PUFAs are important for cellular membrane components and the production of eicosanoids, which are hormone like substances that are the body’s cellular check and balance system. The eicosanoids do not last long in the body, so they have to be produced continuously. The production of eicosanoids can be controlled if one is consuming the correct balance of Omega 6 to Omega 3 PUFAs; balance means good health whereas imbalance leads to disease development.
The EPA (Eicosapentaenoic acid) reduces inflammation and blood clots within the cardiovascular system. Also, clinical tests have shown that diet’s rich in EPA are less inclined to develop inflamed joints (Rheumatoid arthritis), inflammation of the intestines (Crohn’s disease), lupus, asthma, multiple sclerosis and skin disease.
The DHA (Docosahexaenoic acid) has been identified as an ‘essential’ building block of the brain, nerve and eye tissue. It is especially important to developing an infant’s visual acuity and motor skills. DHA is supplied naturally through a mother’s breast milk, providing the mother is eating fish and other marine mammals. More recently DHA has been supplemented through Seal Oil Formula Capsules, which is an excellent source of DHA.
With regards to DPA (Docosapentaenoic acid), it is only found in significant amounts in Seal Oil and nursing mother’s breast milk. It is as important as EPA or DHA and is an effective agent in blood vessel walls. Researchers in Japan (2003) found that DPA has a potential inhibitory effect on tumor angiogenesis (new vessel formation). This means that DPA has an anti-cancer effect.
The composition of these ‘essential’ (dietary elements that the body cannot produce, so they must be acquired through our diet) fatty acids in seal oil are ultimately involved in controlling inflammation, cardiovascular health, myelin sheath development, allergic reactivity, immune response, hormone modulation, IQ, and behavior.
These ‘essential’ fatty acids play a vital role in maintaining the integrity and fluidity of the membranes that surrounds human cells, protecting them from free radical damage (cell attacking molecules which are believed to be one of the main causes of cellular damage and the aging process). Scientific studies have shown that Omega 3 fatty acid deficiency is seen as the leading cause of Westernized Degenerative Diseases such as, Cardiovascular Disease.
The cardiovascular system is composed of the heart and the blood vessels. The heart is a muscle, which is composed of 4 chambers, so when our heart contracts, the blood is pumped out and into the arteries (blood vessels). The arteries (have thick vessel walls), in turn, transport the blood away from the heart, and then the veins transport the blood back into the heart.
Due to our westernized dietary habits, Cardiovascular Disease stops being a remote threat, only to take on a personal relevance. Cardiovascular Disease refers to a class of diseases that involve the heart and/or blood vessels (arteries and veins). It is a result of arterial damage, including such diseases as, Coronary Heart Disease, Atherosclerosis, Hypertension, Arrhythmia, and Stroke.
Currently there are more than 68 million Americans with one or more cardiovascular diseases such as heart disease, heart attack, and stroke; with many more at risk of developing it. Cardiovascular Disease is the top ranking number one killer, accounting for about one-third of all deaths in industrialized countries.
The risk factors associated with Cardiovascular Disease: Elevated LDL cholesterol (bad cholesterol),Elevated serum trigylcerides,Homocysteine (a sulfur-containing amino acid),Low HDL cholesterol (good cholesterol,) Hypertension, Smoking, Obesity, Diabetes, Male, Low-level of physical activity, and Genetics

Fish oil capsules lower in contaminants: study
2/19/04 - CTV News
Avis Favaro,CTV News Medical Specialist
Two months ago, a study was released showing farmed salmon contained higher levels of pollutants -- pesticides and PCBs -- than wild salmon.
Following up on that study, CTV News has looked into the contaminants of fish oil capsules, which are touted as a healthy alternative.
Health Canada urges us to eat a gram a day of fish to get the benefits of the fish oils rich in nutrients called omega 3 fatty acids that seem to protect against a number of diseases.
Yet, after the study on toxins in farmed salmon, some scientists recommended consumers in North America consider eating farmed salmon just once a month.
Some suggested fish oil capsules as a healthy alternative. But the question remained -- how do contaminants in fish oil capsules compare to those found in the fish themselves?
CTV commissioned a study of its own, to measure the contaminants found in fish capsules from dozen manufacturers.
The results were surprising. Not only do the capsules contain the beneficial fatty acids in high concentrations, but they are also cleaner than the fish they came from.

Fat acid clue to cystic fibrosis
BBC News
Sunday, 15 February, 2004
An imbalance of fatty acids may cause the lung inflammation experienced by cystic fibrosis patients, scientists have suggested. They say too much of one acid and too little of another means patients' bodies are more prone to inflammation
In the New England Journal of Medicine, they suggest Omega-3 oils, found in fish, could help correct the imbalance.
But experts warned CF patients not to change their diets until there is more proof they would benefit.
Each week three young people in the UK die from the disease, which is caused by the faulty CFTR gene.
CF causes an abnormally thick, sticky mucus to be produced in the body, causing chronic inflammation of the lungs leading to life-threatening infections.
The average life expectancy for a person with CF is around 31.
