Quote: Adiposity causes inflammation of the hypothalamus

Adiposity is associated with chronic low-grade systemic inflammation and increased inflammation in the hypothalamus, a key structure in feeding behavior.

Obesity-mediated inflammation may damage the brain circuit that regulates food intake. Brain Res. 2011 Feb 10;1373:101-9. 

In other words, excess fatty tissue in obesity harms the hypothalamus, the brain structure that regulates feeding behaviour, and makes it more difficult to control overeating. Through inflammation, excess fatty tissue takes control. The solution, a non-inflammatory diet such as the Paleo diet.

How to remove a dam

An earlier post discussed the removal of the Glines Canyon Dam on the Elwha River, a milestone event which began on September 17, 2011. Above is a time-lapse video of the removal in progress toward the end of last year. I suspect the dentate structure is being created to keep the barge from spilling over the dam as it is demolished.

SUNDAY PALEO / February 12, 2012

A winter day. Eagle County, Colorado.

This Sunday, I review two research studies that demonstrate the health benefits of the Paleo diet. (Maybe you can send your skeptic friends over for a look.) Also, you will find a link to a high-rise urban farm of the future, under construction in Sweden today. Finally, you will find 3 Paleo recipes to consider.

Beneficial effects of a Paleolithic diet on cardiovascular risk factors in type 2 diabetes: a randomized cross-over pilot study.
This small research study compares the Paleolithic diet and a diabetes diet in persons with type 2 diabetes managed with oral medications.

For three months, 13 patients with type 2 diabetes alternately ate a Paleolithic diet “based on lean meat, fish, fruits, vegetables, root vegetables, eggs and nuts” and for another three months ate a “diabetes diet designed in accordance with dietary guidelines.”

The researchers evaluated a number of physical parameters and performed lab tests including a glucose tolerance test on each patient.  

When the results of the two diets where compared, the Paleolithic diet resulted in lower weight, lower BMI, smaller waist circumference, and improved HbA1c, triacylglycerol, and diastolic blood pressure. The Paleo diet also resulted in higher levels of high-density lipoprotein cholesterol, the good cholesterol.

The author's conclusions:

Over a 3-month study period, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in patients with type 2 diabetes.

Bottom line, the Paleolithic diet won hands down.

Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet.
The authors of this study recognize that “contemporary American diet figures centrally in the pathogenesis of numerous chronic diseases-'diseases of civilization'.” They studied whether the Paleolithic diet “confers health benefits…in nine nonobese sedentary healthy volunteers” compared to their usual diet.

The participants consumed their usual diet for 3 days, then “three ramp-up diets of increasing potassium and fiber for 7 days,” followed by a “paleolithic type diet comprising lean meat, fruits, vegetables and nuts, and excluding nonpaleolithic type foods, such as cereal grains, dairy or legumes, for 10 days.”

Compared with their usual diet, the paleolithic diet resulted in significantly lower blood pressure, improved oral glucose tolerance test and  “large significant reductions in total cholesterol, low-density lipoproteins (LDL) and triglycerides.” (emphasis added)

The take home message:

In all these measured variables, either eight or all nine participants had identical directional responses when switched to paleolithic type diet, that is, near consistently improved status of circulatory, carbohydrate and lipid metabolism/physiology.

First Vertical Greenhouse Under Construction in Sweden
Developers in Linkoping, Sweden are building a new kind of urbran farm. Known as the Plantagon Greenhouse, this “greenhouse for vertical farming in cities provides a way to use excess heat and CO2 from industries while growing crops.” The facility will take 12-16 months to complete.

Hans Hassle, CEO of Plantagon, states:

This is a historic day for Plantagon. This ceremony marks the realization of the vision of creating functional sustainable solutions for the growing cities of today and tomorrow, where we can grow food in the cities in a resource-smart way, making use of the special conditions of the city.

Travelling to southern France? You may want to visit the upper Paleolithic cave Abri Pataud occupied by Paleo ancestors 20-40 thousand years ago. The site contains “lots of evidence for Upper Paleolithic art work--drawings, paintings, carvings, personal ornaments, even a venus figurine.” A brief description, including a link to the museum, was recently posted here.

Speaking of venous figurines, here are some thoughts on why they were rotund.

Finally, Nathan Seppa of Science News reports on new research showing how massage helps sore muscle recover:

Researchers from Ontario and California have found clear molecular signs that overworked muscle cells respond to being manipulated by massage. They also found measurable decreases in inflammatory compounds in massaged muscle tissue and indications that muscle cells rev up their energy processors for the inevitable repairs that follow hard exercise.

Chef Harvests Herbs and Vegetables from Urban Restaurant Rooftop Garden. iStockphotoDon't hold your breath for the USDA or a major health organization to recommend the Paleo diet. There is not enough of this food to go around; the diet will not "scale."

However, there is a glimmer of hope in the form of urban farming. In cities throughout the country, the movement is slowly taking shape. This Sunday, we look at some of the recent activity.

In the Salon article, Urban gardens: The future of food?, Will Doig writes:

Right now, urban-grown produce represents a minuscule slice of the food system. But there are several plausible scenarios that could make such food more commonplace in the city kitchen of the future.

...urban farming may carve a path to sustainable success by creating a new type of subsystem within the larger food system — one that’s bigger than boutique but smaller than Big Agra.

More importantly, as noted by urban agriculture pioneer Dr. Dave Schemberger, locally grown food is healthier: 

Chronic illness is exacerbated by eating hollow food which has lost its nutritional value from spending too much time on a truck or grocery store shelf. We can prevent and reverse much of the disease found in our modern life by avoiding processed food and consuming more raw fruits and vegetables close to the time they are harvested.

(However, cooking has it's benefits. Cooking increases access to nutrients in some foods and is believed to have been important in the expansion of the hominid brain.)

Many U.S. cities have active urban farming programs. Last year, San Francisco passed the Planning Code Amendment on Urban Agriculture making commercial garden and small farm sites legal in the city. This year, "Atlanta Mayor Kasim Reed will break ground on the Trinity Ave. farm across from City Hall". A planning department’s proposal in New York City, if approved, would allow "1,200 acres of empty, flat rooftops" to be "eligible for green penthouses."

To find urban farming activities near you, do an online search on "urban farming" and the name of your community. 

Want to become an urban farmer? Try this guide by Novella Carpenter and Willow Rosenthal: The Essential Urban Farmer. Hannah Wallace interviews the authors and poses a number of questions including:

Starting an urban farm demands a lot of work–not to mention money. You need to pay for water, buy liability insurance, equipment, wood and nails for raised beds, maybe even hoop houses. Are there funds would-be gardeners can apply for if they don’t have enough of their own money?

Puerto Arenas on the Straight of Magellan, Chile.

… Dr. Frassetto and her team at the University of California in San Francisco tested the Paleo-diet on out-of-shape volunteers. The group ate lots of food without losing any weight or exercising. “In two weeks, everybody’s blood pressure went down and everybody’s cholesterol and triglyceride levels got better. The average drop was 30 points, which was pretty amazing. It’s the type of drop you get by taking statins for six months,” said Dr. Frassetto.

Paleo Tub Scrub!

By Leslie Why Reap

HA HA, I made you look, didn’t I?  So maybe my new PTS (Paleo Tub Scrub) isn’t truly Paleo due to the absence of bathtubs back in the day, and perhaps it is not truly “mine” since I found it on eHow.com and I didn’t invent it…. BUT by virtue of enthusiastic creation and application and passionate adoption, I have made it mine.  It is mine because we all need to find ways to live more Paleo/Primal, more off the grid than on, with a smaller footprint and more independently of all those wildly profitable consumer goods that toxify our terrain and bodies.  So in an effort to do all of the above AND because I needed to clean my tub and not feel like I was going to die, I decided to try my hand at a Homemade Cleaning Products 101.  First up, a simple and effective Tub Scrub (good for shower walls too), since renamed “PTS" (Paleo Tub Scrub)!  

Since I made a New Year’s Resolution not to play Doctor Google in 2012, I decided to play Chemist Google (or Google Chemist?) instead.  It was a quick search and a short path to find my ideal homemade product.  Would it work?  Why not simply buy a tub cleaner?  They work - right?! Good question.  Actually, that isn’t a really good question because it can likely be answered by your personal experience with tub/shower cleaners.  They are highly toxic.  Or at least they seem to be since most won’t disclose the ingredients on the bottle.  Unless you buy an “organic” one and spend more money which is an attractive option if you don’t have an extra 5 minutes to make your own.  Besides, anything that carries a warning label in two languages that takes up half the backside of the bottle and claims to have “No Obnoxious Fumes!” is surely suspect in my mind.  They make your throat burn and eyes water, and if you have the pleasure of really having to scrub the tub/shower for more than 30 seconds, you will find that you start to get lightheaded as well.   Not the kind of high I want.

Now I can hear the excuses coming, “I don’t have the ingredients,” “I don’t clean my house someone else does”…blah blah blah.  Be a little self-sufficient.  Studies show that people that make, bake, build, and create things are actually happier and more fulfilled.  So get the ingredients, make the stuff and give it to your housecleaner or use it yourself, and then take a deep inhalation and know that you are not poisoning yourself, your family or the environment with that noxious stuff that is so “handy” and “easy.”   Revel in the fact that you MADE something today!

How to make your very own PTS:

  1. 1. 1 cup baking soda
  2. 2. Mixing bowl
  3. 3. 3/4 cup liquid castile soap (I used Dr. Bronner’s which I buy in bulk)
  4. 4. Spoon
  5. 5. Essential oil, for fragrance (Dr. Bronner’s comes with essential oils, wow, step saved!)
  6. 6. Pump-style soap dispenser (I put mine in a pint mason jar)
  7. 7. Sponge or scrubber pad

Pour 1 cup baking soda into the mixing bowl. For larger quantities, you can double or triple the recipe.

Add liquid castile soap, a little at a time, while mixing continuously with a spoon. Keep adding the liquid castile soap until the mixture resembles a slightly thick shampoo. You may end up using more or less than 3/4 cup.

Sprinkle scented essential oil into the mix and stir well. The amount you use will depend on the scent you select and how strong a scent you prefer. Start with five drops, and add more if desired. The fun part of making your own cleaner is the freedom to choose the scent you want - anything from the clean smell of cool cucumber to the more exotic, spicy frankincense. The essential oils are optional.  You can omit them if you prefer.

Pour the mixture into a decorative pump-style liquid soap dispenser. Store any leftover mixture in a sealed container. This cleaning mixture will keep for up to a year. (I didn’t have one of these lying around so mason jar did the trick).

Use the mixture by pressing the pump to dispense a small amount on a sponge or scrubber pad and applying it to the tub. Scrub the tub area and rinse with water.

How to use it:

Do I really need to explain to you how to clean a bathtub?  Google it.  The short version…I applied it with a scrubby sponge to tub and shower walls, scrubbed and rinsed.  Soap scum, dirt, rings, gone but not forgotten as a lovely organic pepperminty smell remained.  No burning eyes, no gasping for air, no polluting the earth!  I love it.

Your Path ~Make it One of Presence, Patience and Enlightenment~

By Leslie Why Reap

The path.  Your path.  In other words, Your Life.  Do you like it?  Do you own it?  Do you say “yes!” to what you want to say yes to and “No thanks” to what you don’t want to do?  It’s a challenge isn’t it?  Owning your path…choosing your path….changing your path if you don’t like the current one.  What about being present and patient on this path?  Pretty tall order but that is what 2012 is for!

2011 was the year of “the new path” for me.  It was unfamiliar and at times difficult and painful, but it was both a chosen path and a gift all at the same time.  My notable 2011 event was that I had brain surgery.  Nothing crazy, not a lot of drama and not a huge deal to me as it was an easily made decision.   It was a big deal, however, for my children, parents, family, and close friends.  I wasn’t scared, I was prepared.  I was ready.  I had done the amazing healing meditations (by Peggy Huddleston), had a big support network and knew that my surgery would be a success.  It was a huge success.   The recovery -well that path is a little rockier than the path leading to surgery, but it has come with something that I would deem nothing short of enlightenment.

Here is a little background information.  All my life I have been an athlete.  I am happiest when I am moving.  I was a decent triathlete and an even better runner until a car accident in February of 2010.  The car accident ultimately led to the brain surgery.   After the accident and prior to surgery, I worked on being able to run again thinking it would make me feel better, ultimately running a marathon in November 2010.  The marathon brought me to my knees, literally.  The diagnosis came just weeks after the race. An MRI showed I had a 17MM herniation of my cerebellum into my spinal column, my brain stem significantly impacted, my 4th ventricle completely blocked, spinal fluid not flowing.   For three months I got very acquainted with my bed while my heroic mom searched for the top neurosurgical team.

Long story short, it was a long three months, but many with this condition suffer with it undiagnosed for years so I was very lucky.   I only saw my children, family and friends for a few minutes at a time before needing solitude.  I was disconnected, but what I realized was that I had been disconnected for months, even years.   All the focus on training and future racing events - but to what end?  What about today?  My children were growing up, and I wasn’t present for them, my mind was elsewhere.  Other things in my life weren’t working, but what was I doing about it?  Not enough.  With this on my mind, I departed for Colorado for surgery.  I was away from my children for 19 days.  Twice I had to call and tell them I couldn’t physically get on the plane to come back to them.  I was too sick; I was in my own self-created, post-surgical downward spiral.

Enlightenment?  Yes, I just didn’t recognize it at the time.  Being several thousand miles from home, I recognized that I couldn’t do belly hugs with my children or tuck them into bed.  I couldn’t read to them or laugh and joke and touch their faces.  I couldn’t hug my brothers or tell them how much they mean to me.  I couldn’t hug all the people that were providing meals and support for my family.  Colorado gave me the gift of enlightenment along with some other gifts:   the gift of being able to walk without faltering,  the gift of thinking and speaking fluidly, the gift of drawing an easy breathe,  and the gift of knowing that when I went to sleep each night I would indeed wake up in the morning.   I had taken all of these things for granted; I had not recognized them as gifts. 

What was the enlightenment you ask?  It was recognizing that the greatest gifts I could give myself and others are the elusive, mindful  acts of presence and patience.   I did not grow up with these gifts, and they are not easily acquired.

It has been 9 months since I returned home from Colorado.  My daughters truly know me now.  When they speak to me I stop, I look them in the eye and give them my full attention.  I give them my presence.  Our connection is unbreakable.  I am also patient with them.  What if something happened and the last words that they heard from my lips were impatient or sharp?  What more can I give them than my time, attention and patience, and they in turn will give it to others.   I make plans for the future, but I live in this day as it is the only moment that I have.   I own my path now.  I choose this path each day.  I say “no thanks,” as freely as I say “yes please!”  Every day is a day to live, a day to breathe, a day to laugh and love.  Ask yourself, am I present in this moment?  Have I chosen the life I am living?  Give yourself and others the gifts of presence and patience in all that you do and these gifts will be returned to you tenfold. 

Welcome 2012, it’s damn good to see you.

Adding color to our walls has not changed much in 25,000 years.By Dr. John

Scicurious, at Scientific American Blogs, notes that the Paleolithic diet is “pretty popular among Americans right now.” However, he questions how well we know the details of our ancestors' diet, especially when it comes to fish. Did our ancestors deep sea fish 40,000 years ago? In Does your Paleolithic diet allow tuna?, Scicurious reviews new evidence from Papua New Guinea and nearby islands, such as a cave in the island of East Timor:

The cave holds evidence of a VERY long period of human habitation, with carbon dating showing artifacts as old as 42,000 years before present all the way to the modern period (or at least around 5,000 years ago). Among the shells, beads, stone artifacts, and bone points, are fish bones. LOADS of fish bones. The authors recovered over 38,000 fish bones, representing almost 800 species of fish. And not all of these fish were shallow water specimens. In fact, there were a lot of Scombridae specimens, the tuna group, and these specimens reached back almost to the base of the bone pile, estimated to be, at the bottom, around 42,000 years old.

Is it dinnertime? Although not fish recipes, here are some great Paleo/Primal meals to consider:

Fajita Frittata with Avocado Salsa

Oven Roast Chicken with Truffle Salt and Thyme

Slow Cooked Lamb Roast

You're eating well and starting to see some results from your Primal or Paleo diet. What about exercise? Is it time to start lifting weights? Maybe do some cardio? These should be easy decisions, but when you consider our Paleolithic ancestors, things get tricky. Josh Noel wonders, if our “modern notion of exercise has gone astray?” Learn more on this brewing controversy at Train like a caveman

Erwan Le Corre, founder of MovNat, suggests the way to determine how to exercise is to ask: What is the best fitness regimen for a tiger (or a tigress)?

So isn’t it high time for a healthy and meaningful paradigm shift in the way society and the fitness industry approaches fitness?  In the way you are personally approaching exercising?  Aren’t you thirsty for authentic human movement?

Here’s the right answer: in order to become and stay optimally fit, a tiger needs to move the way tigers move in their natural biome.  It is that simple.  Tigers will move naturally when they’re free to live the natural life every tiger should live; as will all other wild animals.

Read the post and let me know what do you think. Does it take more for us to regain or maintain fitness than "authentic human movement"? 

Finally, take a look at the recent post by John Michael and contribute your thoughts to Notes on a Manifesto.

John Michael: Notes on a Manifesto

View from Paleolithic rock shelter, Patagonia, Chile

Paleo is unique in that it's an overarching life plan and has actually influenced my perception of eating, exercise, and my body. It's no longer a struggle to lose fat or gain muscle. After almost 3 decades of fighting my body, the Paleo approach has taught me how best to respect and maintain it.

In the blogosphere and on Reddit people are talking about the added awareness Paleo-dieting has brought them. Some came to this diet in their fight against obesity, others to increase athletic performance, but for all going Paleo has created such a level of improvement that they’ve begun to wonder, “Can I apply this logic to the non-dietary aspects of my life?” 

They start by altering their sleeping habits and sun-exposure times. Then they begin to change their shoes, slipping on Vibram Five Fingers. They even modify their exercise routines to mimic the daily exertions of Paleolithic humans. Every change springs from the question, “What is best for my body according to its evolutionary history?”

My own observations of this trend have been informed by the questions, “Can what you eat change how you live?” and, “Can a diet change a culture? 

First, I looked at the Standard American Diet and considered how it came about.

We don’t have time to wait for a meal, much less prepare one. Fast food is born. It’s been a long day, and we’d rather not get out of the car. The drive-thru is engendered. Our high-stress jobs require little physical exertion, and great mental effort, while our grain-based, sugar-laden, processed foods, assisted by television and the computer, and for some alcohol and cigarettes, provide us a temporary relief, alongside long-term damage.

Ignored, the body slowly takes its revenge, as waistlines expand, preventable diseases thrive, and a general malaise settles upon the land. To compound the problem, we treat our ailments with drugs that make our symptoms bearable without curing us. 

Observing the growth of Paleo, I’ve come to speculate on its underlying principles. I took these notes months ago, in the hopes of creating a manifesto, which I intended to call “The Paleo Cosmovision.” Now, curious to know what others might have to add, I’ve decided to crowd-source my ideas.

I use "cosmovision" and not its synonym "world view" because the Paleo Cosmovision is not a perspective on the world, but a vision of the cosmos, of life in its entirety.

There is a simple principle underlying the Paleo lifestyle, and that is that we, as human beings, were designed to eat certain foods, and that we were designed to do certain things and to live in certain environments. Which is to say, then, that our lives have a design.

Extending this principle to its logical conclusion, the goal of the Paleo life is to live in line with the patterns that formed us.

Attention then must be paid to the components of our environments: have we introduced harmful elements into our living spaces? Does the routine in which we live respect the needs of our bodies and minds?

Obviously there are parts of the past that we would rather leave behind us, like constant warfare and other forms of brutality. But we cannot forget that the best parts of us also came from these original human environments; if we shun them for their ability to stimulate our brutality, then we may also perhaps starve those elements of our nature that comprise the best of us.

We are not the products of a pristine hunter-gatherer environment living within a modern world; evolution did not stop at the agricultural revolution. So it is perhaps unwise to think that a truly Paleo lifestyle would entail a complete return to nature; but perhaps the rate of change in our culture has outstripped us - perhaps progress has carried us further away from ourselves than we were ready to go. In which case the work of progress then becomes adjusting itself to the realities of our human condition.

We are modern human beings. We have built the modern world as a way to empower us, to reduce our victimization by the forces of nature and our own brutality. The modern world is no more than a realized dream of empowerment. But the dream becomes a nightmare when it victimizes those who built it.

SUNDAY PALEO / January 8, 2012

This beautiful image of the Omega nebula, a stellar nursery located in the constellation Sagittarius, was taken using the Very Large Telescope located in the Atacama Desert of Chile. Light from these newborn stars will take 6,500 light-years to reach Earth. (image via Wired

Hold on, we are now jumping back to....Paleo bling!? Hang this 9 cm stone pendant around your neck with a leather strap and you would be stylish 25,000 years ago. It would probably go well with your pelt. The pendant, found in the Basque province of Spain, was used for sharpening stone tools. Form, function and fashion.  

Our Paleolithic ancestors' survival depended on stone tools and what we know of their diet points to an overall robust health. Today, even though we have wonderful tools that allow us to peer into deep space, we have lost sight of our original health and our original diet. Although the Paleo diet varied in different parts of the world, it did not include processed foods, sugar, bread, pasta, pastries, cookies, candy….. (That sentence may be a hard to read for some.) If you want to know what the Paleo diet is not, go to your local Starbucks and look at the top shelf. Also, be wary of much of what exists on the second and third shelves.

Fortunately, a growing number of people are rediscovering the original human diet. The State Journal of West Virginia has a story on Kimberly Huneycutt:

“A former California girl, Huneycutt found herself at the age of 40, unhealthy, aged beyond her years and tired after a life spent in the sun and eating a traditional "American" diet that included processed foods.”

"It's been really amazing," says Honeycutt about the transformation she experienced on the Paleo diet. 

Nutritionist Stella Metsovas has developed the Paleo Mediterranean diet. Although the “Mediterranean principles” she uses are not clear from this brief article, the description of Paleo diet is solid:

“The Paleolithic diet consists of grass-fed meat, free-range fowl or wild-caught fish, seasonal fruits and vegetables, and generous portions of healthy fats – including nuts, seeds, avocados, olive oil and coconut oil. Grains, legumes, dairy products, sugar, vegetable oils and processed foods are absent from this diet.”

You might not start at grass-fed, free-range, or wild-caught stage, but switching to fish, meat, vegetables, fruit, nuts and berries will put you leagues away for all that stuff on the top shelf.

Maybe you are concerned about starting the Paleo diet because of harm to animals. Unfortunately, as a look at the numbers in Australia shows, no one gets off the hook on this one. However, the Paleo diet appears to be the better choice. When you compare the use of rangelands versus croplands on animal life, the numbers don’t look good for agriculture.

Relying on grains and pulses brings destruction of native ecosystems, significant threats to native species and at least 25 times more deaths of sentient animals per kilogram of food.

Finally, in the category “if we trash the planet, we trash ourselves”, the good news is that global investment in cleantech companies increased by 13% to $8.99 billion in 2011. Better yet, the Cleantech Group believes “2012 will be an all-time record year for global cleantech investments."

Paleolithic Nutrition: Chronic Inflammation

By John Michael

It was Monday night, and I had just finished packing my bags. With everyone else in the house asleep, I had nothing to do but think about my flight the next day. I would be leaving Denver at seven AM, and arriving in my Midwestern hometown sometime in the early afternoon.

I love eating Paleo, but every now and then, especially late at night, I succumb to the lure of other foods, processed foods… industrial foods.

This time it was my nerves. I get anxiety when I travel, and ever since I was a little boy, I’ve used junk food to calm myself. Normally, I eat well, but when anxiety appears, old habits follow. That’s how I ended up in front of my parent’s open freezer at midnight, with its pale light and steaming air pouring over me. 

Tuesday morning I woke with a tingling rawness in my gums. I’d fallen asleep without brushing my teeth; an empty pint of ice cream was on my bedside table.

After brushing, the gum inflammation subsided, but I was left wondering, Had this always happened before I went Paleo? Or had I just become sensitive?

Then I thought of the other foods that made me feel inflamed. When I ate tomatoes, my entire body tingled slightly. Not to mention what wheat products did to my GI tract. John Michael’s recipe for farts and bloating: just add grain.

Consideration of my irritated gums sobered me. Had I always had these inflammatory reactions to food but lacked the discernment to notice? Had my body been chronically inflamed by the profligate diet of my early years? 

The Search Begins

I’d heard about chronic inflammation on the news, knew it as a silent killer that could secretly spread through my body. But I’d never taken the time to actually learn how it occurred; I’d only heard enough to create a phantom in my mind, a shadowy figure that fear inflated until it loomed over me.

Better, I thought then, to just ignore it.

But I’m not a young man anymore; the damage I do to my body today no longer miraculously disappears tomorrow. Compelled by my irritated gums, I decided to put aside my fear and face the specter of chronic inflammation.

The Mechanism of Inflammation

When a splinter enters my thumb, it incites inflammation. Nearby cells release chemicals, called inflammatory mediators, which activate an autoimmune reaction. In response, blood vessels dilate, filling the damaged area with fluids. This causes swelling and redness, and isolates the injured tissue.

Then immune cells arrive to consume cellular debris and pathogens. When no further damage occurs, the release of inflammatory mediators subsides, and the process of acute inflammation ends.

Unless another splinter pierces my thumb, in which case inflammation begins anew. And if splinters constantly stick my thumb, then it never stops. With irritation never ceasing, cells consistently release inflammatory mediators, and acute inflammation becomes chronic 

Chronic Inflammation Revealed 

Our own cells are often the victims of these responses. The persistent immune assault can wear them down, reducing their effectiveness and increasing the likelihood of damage and death. It’s logical then that chronic inflammation should play a role in so many diseases.

It can cause cancer by damaging cellular DNA, thus predisposing cells to dangerous mutations. And inflammation also aids in the growth of tumors, often hijacked by cancer to assist in its own development. It even appears in Alzheimer’s, with the brains of sufferers displaying all the signs of a chronic inflammatory response. 

One study cited by Dr. John in a recent talk he gave, “New Research on the Role of Nutrition on Neurological Function,” suggests, “Depression belongs to the spectrum of inflammatory and degenerative disorders.” Another study from his presentation notes that when high levels of inflammatory mediator C-reactive protein were found in stroke patients, chances were high they would also have problems with planning, decision-making, and self-control.

The agents of chronic inflammation are many, from lifestyle choices like smoking and diet, to other factors like repeated infection. Obesity incites it, as fat cells leak and rupture, exciting an autoimmune response. Antibiotics, chemicals, and even undigested food can cause it as well.

Avoiding Inflammation

The picture these studies paint is one of the human body as an intricate collection of delicately balanced components, easily destabilized by the introduction of toxic elements.

We can maintain this delicate balance by making good choices, like avoiding cigarettes and other tobacco products. Eating Paleo can re-establish our omega-3 to omega-6 ratio, which is at an unhealthy 1 to 15 in the Standard American Diet.

Spices like turmeric and ginger have anti-inflammatory properties; toss some on your next meal. The probiotics found in yogurt can reduce inflammation by maintaining a healthy gut; if you avoid dairy, then supplements exist to meet your needs. Additionally, keeping a healthy body weight prevents inflammation caused by obesity, and reducing stress helps as well.
