Supplementation implies that you have a void in your basic diet that needs to be filled. It is a solution to a symptom, and not a cause.

Nutrition is at the foundation of health and well being, and every culture in the world already knows the secret to good health: You are what you eat!There is little room for argument surrounding the fact that your body can only repair and fuel your body with the food that you are feeding it. If you are feeding yourself refined, modified, denatured, and otherwise chemically altered variations of food, then how do you expect your body to perform? To use an analogy, would you pour dirty gas into your car and expect it to perform at an optimal level? Probably not.

To restate what I have said in earlier posts, food should not be broken down into micronutrients. There is a popular trend in the media right now to tout the latest magic bullet pill, vitamin, or antioxidant as the cure to X health risk. The problem with this approach is that our place in nature is a part of a larger system. Our genome didn’t evolve to eat the extracted vitamin C from citrus fruits, or isolate whey protein from milk, or iron pills, we evolved to eat the WHOLE FRUIT, and drink WHOLE MILK, and eat WHOLE VEGETABLES… seeing a trend here?

The three macronutrients of protein, carbohydrate, and fat are the building blocks of human life. Keeping your food in the rawest form you can before digestion ensures that you are getting as much nutrition as you can from the food you eat. Excessive heating, processing, and nutrient isolation removes much of the digestive enzymes from food that helps your body process and break down these foods into useful compounds. Without these enzymes, many foods get treated by the digestive system as a threat and trigger a stress response.

Supplements often lack many of the chemical components that allow the body to use them properly. To compensate for this, most supplements increase the amount of raw product you have you ingest to absorb a significant amount of whatever nutrient you are supplementing for. This practice can often lead to allergies caused by repetitive exposure to compounds that agitate the digestive system.

If you feel that you need to supplement your diet with a protein source, or vitamin, you should probably step back and take a look at where your real food diet is failing. A paleo based diet of meat, vegetable, nuts and seeds, some fruit, little starch and no sugar, combined with proper proportions for your body type, should be providing all of the macronutrients, and consequently all of the micronutrients that you need to thrive.

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)

In the video Robb Wolf explains how our body’s resistance to insulin happens very much analogous to they way our olfactory reaction to perfume is very strong when we first smell a new scent. That smell fades however as our noses become desensitized to the perfume’s aroma. To experience the smell with the same intensity as the first inhale, we either have to increase the amount of perfume (similar to having to increase drug dosages to maintain effectiveness), or decrease our exposure to it. The sad reality is that most people choose the former when it comes to insulin levels.

When insulin resistance occurs, the body has trouble releasing the energy that it has already stored in fat cells, and thus asks for more food to burn as instant energy in the form of hunger pangs. If this demand is satiated by carbohydrates, as is common in North American eating habits, the cycle continues to repeat itself, and fat stores grow while energy levels need continuous “topping-up” with more carbs.

To elaborate what I said in the post on the insulin response, eating low Glycemic Index (GI) carbohydrates, in conjunction with fats and protein, will keep your blood glucose levels low, and thus maintain a normal insulin response.

You body is stuck in an evolutionary past where sugar was relatively non-existent. Due to this environmental scarcity, when a sugar source was eaten your digestive system became very good at instantly storing it as fat, not knowing when the next opportunity for such a high energy intake would be.

If you would not like to be in a constant battle with your genetics, limit your intake of high GI carbs, and cut the refined sugar.

If this sounds like a familiar situation, fear not, for this is the work of insulin, the bodies Master Hormone. Sounds menacing doesn’t it? Insulin has earned this title, as it is the key player in both the processing of carbohydrates, and the body’s inflammation response due it’s control over what gets into and out of cells. Inflammation is an underpinning element in many diseases and immune deficiencies. Control your insulin response, and you can help control inflammation.

Fun fact: Carpel tunnel syndrome is an inflammatory response to insulin resistance.

Back to carbohydrates. When we eat a meal rich in carbs, blood sugar levels increase as the carbohydrates are broken down into their basic components – sugars. As blood sugar levels increase, insulin is released in response. Insulin is a storage hormone which moves glucose (sugar) from the blood into the muscles and fat cells for use as energy. In order to visualize this relationship better, take a look at the picture below.

The red and green shaded boxes point out the discrepancies between the peak blood glucose and peak blood insulin levels. This creates a lag in the time it takes for both processes to reach normal levels again (red box).

It is this lag time in normalization of insulin levels which gives us those sugar cravings after carbohydrate rich meals. This is because blood sugar levels are normal but we still have insulin present in the blood and that insulin needs something to do – without sugar to store it gets bored! So it has the effect of asking the body for more sugar. That’s why we get hungry even though we just ate a few hours ago.

If you read my post on triglycerides you will remember that carbohydrates get broken down into simple sugars (glucose) for use as instant energy. When your cells have absorbed all the glucose that they need, a process that is facilitated by insulin, the gatekeeper hormone, the excess is converted to glycogen via the liver. Glycogen is insulin’s antagonist in that it releases fatty acids from storage in response to protein and hunger, and acts to normalize energy levels.

Insulin is also very important for muscle gain (many bodybuilders artificially inject insulin to gain mass), but if you are constantly causing an insulin response by consuming lots of carbohydrates, you run the risk of developing insulin resistance.

Like many processes in out bodies, insulin has an effectiveness threshold, a level at which our bodies perform optimally. The mechanism is analogous drug tolerance, and why drug addicts never again reach the pleasure if their first high with out significantly increasing the intake levels. Our bodies are very quick at adapting to over stimulation, and if insulin is constantly in your blood stream, your cells develop a resistance. Your body tries to counter act this by pumping more insulin into your blood stream.

Why is this bad?

When too much insulin is in your blood stream, and resistance occurs, nothing gets into or out of your cells. This means that all the glucose from the carbs you keep consuming is turned directly into glycogen. Since glycogen stores have limited space in your muscles and liver, the extra glycogen is converted to fat, which has unlimited storage space (especially in the abdomen and love-handles). Furthermore, with nothing getting into, and more importantly, out of your cells, your body can not get at the fat it has already stored for use as energy, and thus tells you to eat more carbohydrates. It’s a vicious cycle, but one that you can get out of.

You have to learn how to control the insulin response to some degree. If you can decrease the amount of sugar you dump into our blood, thereby decreasing the size of the peak in blood glucose levels, the insulin response will decrease accordingly. By leveling off the peaks and valleys in insulin during the day you’ll be able to exit that ‘hunger rollercoaster’ that plagues millions, and reduce your risk of developing insulin resistance.

So how do I manage my insulin levels?

• Lower your carbohydrate intake and CUT THE SUGAR! I can not stress this enough. If you want to lose fat, and increase your insulin sensativity, this must be your first step.
• Choose your carbohydrates wisely. Leafy green plants, and other vegetables that are high in fiber do not trigger a large insulin response.
• Eat carbohydrates in conjunction with fats and protein. Both fat and protein do not cause much of an insulin response and will slow it’s release.
• Get some good sleep!

Chronic high blood pressure, prolonged exposure to low level stress, and lack of sleep all impair tissue sensitivity to insulin. Understanding the relationship between insulin and glycogen is important for understanding why fat loss while maintaining a high carbohydrate diet is nearly impossible. Hopefully you now have a better grasp on what happens when you eat that twinkie, and why saying “it goes straight to my hips” is not just a figure of speech.

If you have further questions, head over to the Ask a Question page and leave one.

Fun fact: Have you ever noticed how long distance runners, while usually very trim, never really get “six pack” abs? This is because the layer of fat around the abdomen is typically cause by increased cortisol levels, a stress hormone that is triggered by lack of sleep and over training.

Can you determine your economic status by how healthy you are?

In my opinion, the answer to this question is NO, because health is independent of socioeconomic status (SES).**

Eating well, and being conscious of your health should be a top priority in everyone’s life. If you agree with Maslow’s hierarchy of needs, it is easy to see how failing to satisfy the needs of good food and health will cause a major weakness in your personal pyramid.

We live in a world in which obesity has reached epidemic proportions. With more than 1 billion adults overweight (at least 300 million of them clinically obese), this extra bulk is a major contributor to the global burden of chronic disease and disability. Often coexisting in developing countries with under-nutrition, obesity is a complex condition, with serious social and psychological dimensions, affecting virtually all ages and socioeconomic groups.

We as North Americans pride ourselves on being part of the developed world and having the resources to feed our population. It is sad that the way we have chosen to feed these people is with refined corn products such as high fructose corn syrup, and meat that has been so pumped full of antibiotics that it’s slowly destroying our immune systems. Combined this with an increasingly sedentary lifestyle and it is easy to see why obesity rates are exploding across all socioeconomic levels.

Figuratively speaking, yes everyone eats, but most of them eat crap!

To get back to Brandon’s question, just as economic status doesn’t determine health, health can’t determine your economic status. It works similar to trying to judge SES by looking at the clothes someone is wearing, or the car they are driving. Almost impossible in today’s credit supported, culture of stuff.

What health can determine or at least positively affect however, is a person’s happiness.

A healthy body, fueled by good food is an excellent vehicle for fun. You will be able to take part in more experiences, not miss out due to illness, and living your life upright and able instead of overweight and in a chair.

If you are worried about how to finance your new healthy way of eating, consider this: An apple cost less than a bag of chips, water is free, and when you stop spending money on cheap carbohydrates which have little food value, and only make you feel more hungry. You will have all that money to spend on good quality protein and fats.

** In the developed world.

To answer this question, let’s look back into our past for a minute.

What we know as humans (the genus Homo in one form or another) have been on Earth for about 2 million years, and their predecessors were here up to 7 million years ago.  Combined, these early humans had around 9 million years to adapt to a diet that remained relatively unchanged for most of that time.  We became, through millions of years of evolutionary trial and error, a species of omnivores who were able to derive energy from both plants an animals. This ability to eat a variety of foods allowed us to maximize our energy intake from our surroundings, but it also helped keep our population in check, because only a certain amount of calories could be obtained from hunted animals, and foraged plants (many plants in their raw forms, like grains, beans and potatoes, are inedible and even toxic to humans).

This all changed around 10,000 years ago however, with the remarkable discovery of cooking. Cooking granted us access to calorie rich food such as grains, beans, and potatoes because the heat destroyed enough of the toxins and enzyme blockers to render these plants edible, forever changing human histroy, and in turn, our diet. The effect of cooking had an enormous effect on our food intake- perhaps doubling the number of calories that we could obtain from the plant foods in our environment. Other advantages were soon obvious with these foods:

• they could store for long periods (refrigeration of course being unavailable in those days)

• they were dense in calories- i.e. a small weight contains a lot of calories, enabling easy transport

• the food was also the seed of the plant- later allowing ready farming of the species

These advantages made it much easier to store and transport food. We could more easily store food for winter, and for nomads and travelers to carry supplies. Food storage also enabled surpluses to be stored, and this in turn made it possible to free some people from food gathering to become specialists in other activities, such as builders, warriors and rulers. This also caused an explosion in the human population and in turn set us on the course to modern day civilization. Agriculture, factory farming, and the refining and processing of food into… something other than food, were technologies what were soon to follow.

What does this mean for me?

For millions of year our bodies had to adapt to eating mostly meat, fish, fowl, and the leaves, roots, and fruits of many plants. This diet has been coded into our DNA, and it is the diet that humans function most optimally on. Proof of this can be found in the few remaining hunter-gatherer tribes still living in the world. Most, if not all are strong, fast, have straight teeth and perfect eyesight. Also, cases of arthritis, diabetes, hypertension, heart disease, stroke, depression, schizophrenia and cancer are also absolute rarities.

The common factor: Lack of exposure to a Western diet!

So why fight your genes? If you need a diet to follow, why not follow the one that your body has been designed by time for?

How do I follow a Paleolithic Diet?

I will borrow from CrossFit’s Greg Glassman on this one. He has very succinctly reduced the Paleo way of eating into a few simple words.

Eat meats and vegetables, nuts and seeds, some fruit, little starch, and NO sugar.

That’s all folks. So simple a 5 year old could figure it out. Memorize this line, ingrain it in your mind, tattoo it on your body if you must. These words: Eat meats and vegetables, nuts and seeds, some fruit, little starch, and NO sugar, should ring in your head every time you are thinking about food.

To elaborate a little, what Coach Glassman is saying when he shortened the Paleo diet to this simple sentence is:

• Try and keep your food shopping to the perimeter of the grocery store.
• If it comes in a box, or needs a nutrition label to tell you what is in it, IT’S NOT FOOD!
• If doesn’t expire, IT’S NOT FOOD!
• If you are eating out, get extra veggies and skip the potatoes, fries, sweet potatoes, etc.
• Do not eat grains, pasta, bread, rice or beans, all of which wouldn’t have been available to our Paleo ancestors.
• Make sure you are eating enough good fats. (Fish Oil especially!)

Yes this is a low carbohydrate diet, and what carbs you do consume should be coming from green, leafy vegetables. More on why we should all be lowering our carb intake can be found in my article on triglycerides. Also, as mentioned above, evidence of the lower-carb, Paleo diets effects on the body can be seen in the body compositions of the few remaining indigenous tribes scattered throughout the world.

More details about the Paleo way of eating can be found in Loren Corain’s excellent book: The Paleo Diet: Lose Weight and Get Healthy by Eating the Food You Were Designed to Eat.

The final word.

For every food decision you make, ask yourself this question first: Would a caveman have eaten that?

We may not live in a Paleolithic world, but our body, and it’s biological process are very much a relic of that era. On the time line of human history, our advances in food technology are very recent (2 million vs. 10,000 years), and with evolution being a slow process, our bodies haven’t had a change to catch up to our brains.

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…

Some triglycerides, like those resulting from the breakdown of trans and saturated fats, are not stored as fat, but remain in your blood stream. This is where the problem with triglycerides lies. All this excess material floating around in your blood will cause it to thicken and become sludgy, which increases the chances of blockage or clots forming. The result of which can be a heart attack of stroke.

So what can I do to reduce my triglyceride levels?
The common misconception, and the one that has been propagated by the media, is that since triglycerides are essentially fat, then fat should just be avoided in the diet… right? WRONG!
Your body needs fat to maintain optimal functioning as there are many processes that NEED fat to take place, vitamin absorption, joint lubrication, and building cell membranes and hormones for example.

That being said, you should however avoid the bad kinds of fat – transfats and hydrogenated oils found in margarine, processed and refined foods and fast food. These transfats are chemically altered substances, and as such your body does not know how to handle them properly. They are foreign to the body and therefore dangerous to your health.

The real answer: CUT THE CARBS!!! (And get some fish oil).

Fact: Your body does not need carbohydrates to function. Carbs are not used as a structural component in the body like protein and fat; they are only used as a form of fuel. Moreover, humans can, and have existed quite easily without ever eating carbohydrates, and excess glucose in the blood stream is actually toxic to humans unless being burned immediately as a fuel. Since out hunter/gatherer anscestors did not have access to as many carbohydrates as we do today, (and because the Twinkie hadn’t been invented yet) our bodies developed several mechanisms for generating glucose from consumed sources of fat and protein.

Study after study is being released in support of a lowered carbohydrate diet, and proving the link between carbs and triglycerides. According to a publication by P.K. Reissell’s group at Harvard in 1966, it was clearly established that Omega 3 fatty acids and Vitamin C, combined with a low carbohydrate diet, can dramatically reduce your triglyceride levels. Omega 3 fatty acids can help with cholesterol as well.

In summary:

1) Consuming carbohydrates creates high glucose levels in the blood stream, and excess glucose, once your cells have had their fill,  turns into triglycerides.

2) Fat does not make you fat. Fat consumption causes no insulin response, and as a result promotes the burning of both dietary and stored fat as fuel. And since the storing of fat only occurs if insulin tells your cells to open up, and only eating carbs/sugar can make that happen, replacing carbohydrates with good fats will help your body function properly, and help you REDUCE fat stores.

3) Following a no-fat diet is dangerous, as is eating too many carbohydrates. Your body needs fat to function, it does not need consumed carbohydrates, and is very capable at producing it’s own from fat stores.

Get your triglyceride levels checked
Make sure you get your triglyceride levels checked as part of your next blood test. Whether or not your triglyceride levels are high, you should do your part to keep levels down, following the tips on this page.

The normal level of triglycerides in your blood should be up to 199mg/dL. This is the level of triglycerides in the average healthy person.

The optimal level of triglycerides in your blood should be under 100mg/dL.
