Fish Oil

I know in a previous post about supplementation, I said that I preferred not to take supplements and to just choose real, nutrient dense, whole foods, to get a balanced diet, but the truth is that I do supplement.

The reason I didn’t include fish oil in my supplementation post is because I don’t see it as supplementary to your diet, I see it as essential!

We have long known that an improper balance of the omega-3 to omega-6 fatty acid ratio is a key factor in many illnesses and ailments that plague millions of people who are hooked on a Westernized diet. in fact, a study from The Center for Genetics, Nutrition and Health has shown that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1-17/1. A prime reason for this deficiency in our omega-3 levels is due to our lowered consumption of cold-water fish.

The pile of research papers being published showing the benefits of taking about 2-15g (depending on body size) of high quality fish oil per day grows at an almost exponential rate, as well as the list of “itis’s” that seem to be prevented by taking a fish oil supplement and maintaining a healthy omega fatty-acid balance.

Still not convinced? Here are 7 proven omega 3 benefits you should know about:

1. Less Pain and Inflammation. Omega 3 fatty acids, particularly EPA, have a very positive effect on your inflammatory response. Through several mechanisms, they regulate your body’s inflammation cycle, which prevents and relieves painful conditions like arthritis, prostatitis, cystitis and anything else ending in “itis.”

2. Cardiovascular Health. Omega 3 fatty acids have also been proven to work wonders for your heart and the miles and miles of arteries and veins that make up your cardiovascular system. They help to lower cholesterol, tryglicerides, LDLs and blood pressure, while at the same time increasing good HDL cholesterol. This adds years to your life expectancy.

3. Protection from Stroke and Heart Attack. When plaque builds up on arterial walls and then breaks loose, it causes what’s known as a thrombosis, which is a fancy way of saying clot. If a clot gets stuck in the brain, it causes a stroke and when it plugs an artery, it causes a heart attack. Research shows omega 3 fatty acids break up clots before they can cause any damage.

4. Better Brain Function and Higher Intelligence. Pregnant and nursing mothers can have a great impact on the intelligence and happiness of their babies by supplementing with fish oil. For adults, omega 3 improves memory, recall, reasoning and focus. You’ll swear you’re getting younger and smarter.

5. Less Depression and Psychosis. Making you smarter is not all omega 3 does for your brain. Psychiatry department researchers at the University of Sheffield, along with many other research studies, found that omega 3 fish oil supplements “alleviate” the symptoms of depression, bipolar and psychosis (Journal of Affective Disorder Vol. 48(2-3);149-55).

6. Lower Incidence of Childhood Disorders. Just to show how fish oil fatty acids leave nobody out, studies show that children (and adults) with ADD and ADHD experience a greatly improved quality of life. And those with dyslexia, dyspraxia and compulsive disorders have gotten a new lease on life thanks to omega 3 oils.

7. Reduction of Breast, Colon and Prostate Cancer. And finally, omega 3 fish oil has been shown to help prevent three of the most common forms of cancer – breast, colon and prostate. Science tells us that omega 3s accomplish this in three ways. They stop the alteration from a normal healthy cell to a cancerous mass, inhibiting unwanted cellular growth and causing apoptosis, or cellular death, of cancer cells.

* The above list was taken from work by nutrition and physical therapy expert, Michael Byrd. Byrd writes about his pursuit of wellness, the extraordinary healing power of natural whole foods and many of fish oil’s benefits at this omega 3 web site.

Some other benefits that Byrd doesn’t mention are the effects that supplementing with fish oil can have on body composition. A study published in the American Journal of Clinical Nutrition showed that taking a daily intake of fish oil and regular exercise both reduce body fat and improve cardiovascular and metabolic health. The reason being that fish oil lowered triacylglycerols, increased HDL cholesterol, and improved endothelium-dependent arterial vasodilation, or, in understandable terms, lowered fat stores, increased good cholesterol levels, and improved blood flow.

Some things to look for when choosing a fish oil supplement:

Pharmaceutical Grade

  • Check that your bottle of pharmaceutical grade fish oil has a Lot Number that has been posted on an official IFOS (International Fish Oil Standards) consumer report site such as IFOS.
  • Check to ensure that you are buying a TG (natural) PGFO and not an EE (synthetic) PGFO.
  • Check the ingredient label to ensure that the pharmaceutical grade fish oil has a 60% Omega-3 concentration and complies with the CRN and WHO standards.
  • Ask your supplier for a Certificate of Analysis and look for its 5 star rating to confirm that the pharmaceutical grade fish oil has exceeded these international standards.

Oil Source

You want your fish oil to come from a source that is as close to the bottom of the food chain as possible. Heavy metals (such as mercury) that accumulate in the body’s of fish get amplified as they move up the food chain. Many commercially sold fish oil’s use wild salmon as their oil source however, as salmon is a predatory fish, it tends to have high trace levels of heavy metals.

Search for fish oils that are sourced from smaller fish species, like sardines and anchovies, that have eaten the omega rich algae directly.

Docosahexaenoic acid (DHA)

There are two main types of Omega 3 fatty acids found in fish oil, DHA and EPA. DHA plays a most vital role in promoting good health. More than half of our brain’s mass is made up of fats, and of these fats, DHA accounts for over half. This is one of the most reveling factors that show why DHA is so important to us.

It has been proven that numerous mental conditions such as depression, anxiety, mood swings, bipolar disorder, Alzheimer’s disease and Attention Deficit Hyperactivity Disorder (ADHD), among others, are caused due to a DHA deficiency. DHA is also the more important omega 3 in reducing tryglycerides (blood fats closely related to cholesterol) and in helping to reduce or prevent heart rhythm abnormalities, one of the major causes of heart disease deaths. Heart disease is accompanied by cardiovascular inflammation, and DHA has the most potent anti-inflammatory effect of the omega 3 oils. Memory and focus have also been proven to improve with consistent use of fish oil supplements. Therefore, if you want to benefit from fish oil supplements, make sure you are using one that has high DHA levels.

Diet: Another Four Letter Word

It seems these days that any mention of the word diet brings a common look of skepticism from whoever you’re talking to. Why has this happened? Is it because the market is over-saturated with fad diets? The fact that the diet section in the book store is slowly consuming more and more floor space? Or is it because so many of these so called “diets” simply don’t work?

Popular media is filled with reports on “the newest health study”, and ” the latest health product”, and the sad truth is that we eat it up. We have become lazy as a society, and are always looking for the next magic pill that will make us look better, or feel more healthy. The hard to swallow (no pun intended) reality is that there is no magic pill, and healthy eating can be achieved only through smart choices and hard work.

The general vibe I get from people when talking about nutrition and their diet is a feeling of being overwhelmed, and understandably so. It is hard not to feel overwhelmed by today’s health crazed media constantly feeding us study after study after study all based loose correlations and bad science.

I am here to tell you that it doesn’t have to be so difficult. You may not know it, but your body knows exactly what is and isn’t good for you. Acne, allergies, diabetes, heart disease, cancer… the list is long on human ailments that have been linked to a Western diet that is high on carbohydrates and refined sugar. A short search on Google Scholar reveals study after study showning that cultures with diets that have remained relatively unchanged for hundreds if not thousands of years show little to no signs of most common Western diseases. Could it be that perhaps our brains have gotten too smart, and left our bodies in the evolutionary dust? I would argue yes.

If we look at the time line of human existence on Earth (roughly 2 million years), modern agriculture, cooking, and food production practices have only been around for about 10 000 years. That’s less than 1% of out time on this planet. Taking this into consideration, it should come as no surprise then when our radically changed diet causes all kinds of diseases to pop up. Our bodies simply haven’t had time to adjust. Though we may be sending people into space with our brains, we are still living in caveman bodies, and it is for this reason of slow digestive evolution that I advocate a Paleolithic way of eating.

Meat, vegetables, nuts and seeds, some fruit, little starch and NO SUGAR!

Pretty simple.

Don’t be fooled by the four letter word, this is not a diet in the modern definition of the word. This is the way your body wants to eat. It is the way we have evolved to eat. It requires no special foods, no book you must follow, has no late night infomercials, and no easy payments of $49.99. All it requires is a choice. A decision to choose not to eat products that aren’t food. Everything you really need to know about diet, nutrition, and food is summed up in these simple words:
YOU ARE WHAT YOU EAT.

Feed your body crap, feel like crap. Simple.

Eat real food.

Gary Taubes Defends Eating Fat.

Gary Taubes, author of Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health defends his position that fat is not the cause behind North America’s obesity epidemic, but rather that fat may be a key to mitigating many of the problems cause by a poor, carbohydrate rich diet. Taubes discusses how refined carbohydrates are the elephant in the room that health officials fail to acknowledge as the root cause of many ailments associated with a Western diet. Watch Taubes speak on Getting Your Money’s Worth with Judith West.

Milk. Part 1

Shannon recently asked:

What is the truth behind chocolate milk? I have heard that it is better for you than regular milk, and that you should drink it after a hard work out.

The answer to this question requires some background information on milk, so lets take a step back and look at the broader topic of dairy in general.

The verdict on dairy’s effectiveness as a healthy nutrient source has not been passed yet. There seems to be a war raging between those for the consumption of milk, mainly the dairy industry, and those against it, mainly vegan activists, and People for the Ethical Treatment of Animals (PETA).

As in most wars unfortunately, truth is usually the first victim, and the dairy battle is no exception. Propaganda put out by both parties of the debate have left little room for objective investigation, and truthful reporting of the facts.

Milk, it would seem is yet another case of the West’s industrial complex destroying a food that was once a valuable source of nutrients. Much like beef, chicken, and pork, our quest to squeeze the most profits out of a resource has left it barren of nutrients, and full of unknown additives. This shift is not just happening in animal products. Fruits and vegetables have long been selected for genes that express themselves as the best looking, best tasting, and longest lasting produce. Sounds good doesn’t it? Unfortunately, these traits have come at the detriment of our nutrition and health, as nutrients were needlessly bred out in favour of a taste (Read: Higher sugar content).

Similarly, through the processeses of pasteurization and homogenization, milk has been effectively stripped of most of it’s natural enzymes and bacteria that are necessary for the proper digestion of dairy products.

Furthermore, the common misconception that fat is evil has lead to the mass production of reduced fat milk.

Never drink reduced fat milk. (skim, 1%, 2%…)

Fat is taken out milk through a process that over-heats the milk until is it becomes a powder. The fat is separated, and then water is added back to the powder until a milk like consistency returns. You are essentially drinking water with milk ingredients to it. Not milk.

The heat, and exposure to oxygen during the powdering process also damages cholesterol in the milk, which can cause injury to your arterial cells, as well as cause a pathological buildup of plaque in the arteries similar to having high triglycerides.

Heating milk also:

  • Alters milks amino acids, lysine and tyrosine, making the proteins in milk less available for use.
  • Lowers Vitamin C content as much as 50%.
  • Lowers the water-soluable vitamin content as much as 80%.
  • Destroys vitamin B12 completely.

To mention just a few…

These destroyed vitamins are added in artificially after the pasteurization and fat reduction processes so that they may appear on the nutrition label.

If you would still like to consume milk, your best option is to try and find a source of raw milk. Unfortunately, raw milk is illegal to buy in Canada, however, the option does exist to buy a share in a cow. Drinking raw milk from a cow that you own is not illegal. Also, cheese is still allowed to be made from unpasteurized, raw milk. Emmental and Gruyere are just a few of the options.

The second best alternative to raw milk is to buy whole milk, or switch to goats milk which can still be bought in a raw form.

It seems like many other foods, paying attention to the source is the best way to ensure you are eating quality dairy. Furthermore, just as our diet affects our health and performance, the diet of our dairy source is equally important. I will cover importance of what cows are built to eat, and how that is important to humans in the second part of this series.

I admit I have digressed from Shannon’s original question, but it was necessary to formulate a complete answer. As you have read, milk is a good source of protein and vitamins… in it’s original state. Commercial production however, has destroyed most of what is good about milk, and the nutrients that it does contain are artificially inserted backing into the milk product.
Also milk, being high in lecithin produces a high glycemic load, and thus a high insulin response. Adding chocolate syrup (sugar) to milk adds to insulin response, and should thus be avoided.

There was a study however, published in 2006 which indicated that chocolate milk aids in recovery when taken after intense athletic workouts. The study authors believe this to be due to its ratio of carbohydrates to protein, among other nutritional properties. The study was small in scale and partially funded by the dairy industry, but the results may warrant further study. (“Chocolate Milk: The New Sports Drink?”, Associated Press, 24 February 2006)

Triglycerides

What are triglycerides?
Triglyceride is the scientific term given to the fat stores that your body created for use as energy when it has run out of glucose to burn from carbohydrates.

When you eat a carbohydrate, your body breaks it down into simple sugars known as glucose, which is an instant energy source for your cells. The glucose in your blood stream triggers an insulin response, and your cells open up to take in energy. When your cells have absorbed all the glucose that they need, the excess is converted to glycogen via the liver. Glycogen gets stored in your muscles ready for the next time you exert yourself physically. The more muscle you have, the more glycogen you can store, this is why bodybuilders can consume massive amounts of carbs.

Once your muscles have had their fill of glycogen, the excess is sent back through the liver to be converted into triglycerides to be stored as fat. And as is evident from the high obesity rates in North America, the body can always find a place for more fat.

Note: Not all fat is created equal… Continue reading →
