7 Pillars of Health: Improving Health in The modern environment

The default in nature is health, so why are we fat, sick and broken? It is because our environment has change, our bodies have not. We share 99.7% of the same genetics as our relatively disease free hunter-gatherer ancestors yet eat worse, move less, sleep worse, encounter more stress and toxins, and wonder what the cause is of chronic disease. It's really not that hard! Take control of your health with the 7 Pillars of Health.

The default in nature is health, so why are we fat, sick and broken?

It is because our environment has changed, our bodies have not. 

Looking back 10,000 years when we lived as hunter-gatherers people ate nutritious foods, got significant amounts of “exercise” outside in the sun as they carried out their daily activities. This was followed by an equal amount of downtime that provided for adequate rest and the development of remarkable social connections which literally extended from the cradle to the grave. Although running from the occasional tiger and lack of wi-fi made it far from an idyllic paradise, there is little evidence of obesity or chronic disease.

This is in stark contrast to our modern environment where there is an epidemic of poor health (diabetes, depression, cancer, obesity, heart disease etc.), yet we continue to wear our constant stress, long hours in the office, sleep deprivation and ability to eat like a garbage disposal as a badge of honor. Perhaps with the fact that we share 99.7% of the same genetics as our hunter-gatherer ancestors we can further understand that the problem is not us, but within the environment we live.

So, how can we affect change? Unfortunately, there is no magic pill, but there are pillars (seven to be exact!) that were created to serve as a guide to promote better health in our current environment. The follow is a brief overview of what will be covered in 7 Pillars of Health class:

Nutrition

Food is energy and we use the calories it contains along with the vitamins and minerals to carry out specific tasks like digestion, regeneration and repair (sleep), detoxification as well as managing our stress.

Questions to think about regarding Nutrition:

  • What will it do to my blood sugar?
  • Does it contain quality protein?
  • What kind of dietary fat does it supply?
  • What is our food’s nutritional status?

Movement

Movement is more than just exercise, it is the ability to demonstrate strength and ease throughout an entire range of motion. Movement is a dynamic process not a single event. Your day should be comprised of movement — squat, hinge, lunge, hang, climb, press, pull, carry — as opposed to separating it into a single hour of the day. 

Questions to think about regarding Movement:

  • What happens when we don’t move?
  • How can we improve movement?
  • Is one type of movement better than another?

Digestive Health

The health of the gut determines what nutrients are absorbed and it is often said that we are what we eat, but it is more accurate to say, we are what we absorb. Therefore, digestive health should be defined as the optimal digestion, absorption and assimilation of the food.

Questions to think about regarding Digestion:

  • How is the digestive system supposed to work?
  • How can your gut affect your overall health?
  • What are common issues and how do we get them?
  • How can we improve digestive health?

Sleep

Sleep is not the absence of wakefulness. Sleep acts as a barrier between the individual and the environment that allows the body to regenerate physically and recalibrate mentally. This is accomplished best with 8-9 hours of uninterrupted sleep, where it is as easy to fall asleep as it is to wake up at your scheduled time without the need for an alarm or stimulants.

Questions to think about regarding Sleep:

  • Why is sleep important to our body and brain?
  • How can we fix sleeping issues?

Stress

Stress is the response to any stressor in our internal or external environment that acts as a threat to knock our body out of balance. The purpose of stress is to help our body cope with stressors and survive. Your resiliency, energy, endurance and life all depend on the proper functioning of the stress response.

Questions to think about regarding Stress:

  • What constitutes as stress?
  • What happens when our homeostatic balance is threatened?
  • What happens when we are faced with chronic stress?
  • How can we alleviate stress?

Detoxification

Detoxification is an ongoing physiological process which involves the mobilization, transformation and elimination of toxins from external and internal sources.

Questions to think about regarding Detoxification:

  • What is a toxin and how is it processed?
  • Why is detoxification important?
  • How can we lessen our toxin burden?

Community

A community is a shared environment with like-minded people in pursuance of similar goals where individuals included provide positive support system that allows for trust in one another and the freedom to express themselves freely.

Questions to think about regarding Community:

  • Do you share similar values and goals with those around you?
  • Do those around you provide a positive support system?

It is important to understand that no Pillar is more important than another. Instead, achieving optimal health is about proper balance between all Pillars. The sooner we can incorporate the lesson’s the 7 Pillars offer into our life's the better we will be able to live and thrive. When stress, sleep disruptors and environmental and emotional toxins are removed and replaced with balance, purpose, nutrient density, nontoxic products, rest, exercise and healthy relationship, the body becomes incredibly resilient. Our medical system has spent billions of dollars researching health, yet it's going to be hard to come up with a better health recommendation than the sum of what the 7 Pillars offer; eat whole, unprocessed foods, move frequently (preferably outside in the sun), avoid stress so you can sleep like you are on vacation and surround yourself with loving relationships. While we cannot (and probably would not) go back in time and sleep in caves again, we can begin to focus on resurrecting dietary and lifestyle approaches that are more in keeping with our genetics and our ancient metabolic systems, that have become disturbed by the environment we find ourselves in in modern life. It is the purpose of the 7 Pillars of Health to teach you how these disruptions are the cause of our poor health and how each of us can rectify it.

The Interplay Between the Gut and Brain

The classic approach to understanding the gut is that it is simply a collection of organs designed to digest, absorb, and assimilate the food we eat. While this isn’t incorrect, it does not provide the full picture. The gut is full of organisms all working on a wide variety of physiologic actions that help to regulate immune system functioning, detoxification, inflammation, neurotransmitter production and hormone signaling. Without proper maintenance we can have negative effects to our mood, libido, sleep, metabolism, immunity and even our perception of the world and clarity of our thoughts.

Ok, so how do things get out of hand? The overall health of our mind and body is dependent on a diverse population of good organisms in our gut, when populations fall and bad organisms take control we get ill. A loss of diversity in microbial species can be attributed to a culture that favors an unbalanced diet low in plant fibers, the overuse of antibiotics as well as overly sanitizing everything. Understanding this may help to explain why we suffer from rising rates of “western” illnesses that are not seen nearly as much in traditional, mostly agrarian cultures.

Depression, ADHD, obesity, autism, psoriasis, rheumatoid arthritis, cardiovascular disease, Crohn’s disease, asthma and Alzheimer’s have been linked to inflammation in the gut. The causes of gut inflammation vary from person to person but generally stem from poor dietary choices and chronic stress. Consuming a diet high in sugar elevates blood sugar levels which stirs up inflammation in the bloodstream as excess sugar can be toxic if it isn’t swept up and used by the cells. It also triggers a reaction called glycation – the process by which sugar binds to proteins and certain fats, resulting in deformed molecules that function inefficiently. The body recognizes these molecules as abnormal and sets off an inflammatory reaction. In the brain, these structures contribute to degeneration of the brain and its functioning.

The degenerative effects of our dietary choices do not stop at sugar. The ratio of omega-6 to omega-3 fats also come into play. Omega-6 fats dominate the western diet; these pro-inflammatory fats are found in the many vegetable oils used for manufacturing of all processed foods and have been linked to an increased risk for brain disorders. Omega-3 fats, on the other hand – ones found in olive oil, fish, flaxseed and grass-fed animals – boost cognitive function, help to thwart inflammation and can actually counterbalance the detrimental effects of high consumption of omega-6. Anthropological research has revealed that our ancestors consumed a ratio of omega-6 to omega-3 fats at roughly 1:1. Presently, the average western diet is made of as much as 10-20 times more omega-6 fats than what our ancestor ate.

Inflammation due to poor diet elevates a stress hormone called cortisol, which causes some damaging effects on the gut. These elevated levels have the ability to change the mix of bacteria, increase the permeability of the gut lining, and enhance the production of inflammatory chemical coming from immune cells, called cytokines. These cytokines ramp up inflammation in the gut leading to further permeability and also directly and negatively affect the brain making it more susceptible to mood disorders. This effect was studied by Japanese researchers who looked at mice that lacked a microbiome (germ-free mice), it was found that these mice overreacted to stressful situations stemming from an exaggerated HPA (hypothalamus-pituitary-adrenal) response. In other words, the lack of beneficial organisms in the gut can lead to a more damaging outflow of cortisol, thus leading affected individuals to perceive certain events as more stressful than those who have a healthy gut.

Cortisol is also uniquely tied to our circadian rhythm – the ebb and flow of hormones through the 24-hour day that factors into our biology and whether or not we’re feeling alert or tired. Insomnia is a common symptom in mood related disorders and its now known to be linked to the health of our gut. Without optimal health in our gut environment we cannot produce adequate levels of serotonin – an inhibitory neurotransmitter necessary for sleep and mood regulation. Roughly 80% of the amount of serotonin in the body is manufactured by the nerve cells in your gut and many neurologists and psychiatrists are beginning to realize that medications are often less effective in treating sleep and mood disorders than dietary changes are. Interestingly, it is thought that the actual mechanism for modern antidepressants may have nothing to do at all with their effect on serotonin and everything to do with decreasing inflammation.

Another widespread brain disorder linked to the gut is ADHD. The inhibitory neurotransmitter GABA is seen as being largely deficient in the brains of ADHD children. Deficiencies in GABA activity would mean that areas of the brain would be put into overdrive. So what’s triggering this lack of GABA, and how can we increase brains levels? GABA is manufactured in the body from the amino acid glutamine, but the conversion of glutamine requires the presence of what are called cofactors – chemicals necessary for a specific reaction to take place. Specifically, this conversion demands the affected body to be able to absorb and assimilate both zinc and pyroxine (vitamin B6) through food sources, yet without healthy gut flora these cofactors cannot be processed efficiently thus leading to the observed deficiency.

At one point in time it was largely thought that the instance of a “gut feeling” was nothing more than some ambiguous association between the interworking’s of our gut and brain, however upon further investigation it has been shown that there is, in fact, a distinct connection governing this relationship. Serving as a direct link, the vagus nerve that controls impulses and relays information from our gut to our brain and it is for this reason that the health of our gut plays a large role in cognitive function. By understanding that there is a connection, we can find a better way to promote health and prevent diseases.

How does Histamine aid in the secretion of gastric acid?

This is a very interesting question. As I’m sure you are aware, the regulation of stomach acid/enzyme production and secretion is a necessarily complex subject. The stomach has to be able to be turned off when we aren’t eating, but be rapidly turned on when we do eat a meal. In short, histamine acts to increase hydrochloric acid (HCl) secretion by cells in the stomach lining called parietal cells. The story is a little more involved though.

There are lots of cells that make up the lining of the stomach. One kind of cell is the G cell. The G cells are directly innervated by the vagus nerve (one of the cranial nerves). Special nerve fibers in the vagus nerve secrete a chemical called gastrin-releasing peptide. This tells the G cells to release a paracrine (a chemical reeased by one cell that affects cells nearby) hormone called gastrin. The gastrin is detected by enterochromaffin-like (ECL) cells by receptors on their membranes (one of these receptors is the CKK2 receptor). When they detect the gastrin they begin to synthesize and release histamine. Parietal cells then come into play. They have several different kinds of receptors on their surface. One, the H2 receptor, detects histamine. When the ECL cells flood the lining of the stomach with histamine, the parietal cells are cued to release HCl. They also have receptors for gastrin (the same chemical released by the G cells) and acetylcholine, a neurotransmitter. Any of these chemicals can stimulate the parietal cells to secrete HCl into the stomach. The website links below offer some great illustrations of this admittedly complex pathway.

Like many activities our body must carry out, stomach acid production is highly regulated. Many stomach diseases (such as ulcers and GERD) are either directly or indirectly caused by a lack of regulation of HCl in the stomach. In this way, stomach acidity can be decreased by blocking vagus nerve stimulation, by blocking gastrin- releasing peptide release, by blocking gastrin release, or by blocking histamine release. Neat, huh?
