Essential Oils, Phytoalexins, Drugs Are All Antibiotics

---  the other 200 posts  ---
Superbug multidrug resistant plasmid
A recent, informative article by Tori Rodriguez for The Atlantic suggests that,


I want to discuss other ramifications of using essential oils as antibiotics to avoid multiple antibiotic resistant superbugs.

The logic for using essential oils in place of medical antibiotics is compelling: 
  • Essential oils are extracts of plants, which have myriad traditional uses, including food.
  • Most antibiotic use is to increase livestock production. 
  • Antibiotics selectively kill gut bacteria in livestock and make them obese.
  • Antibiotic resistance occurs within a week of use in livestock (or people.)
  • Medical antibiotics are quickly losing efficacy.
  • Antibiotic resistance genes quickly move from agriculture to superbugs to people.
  • Plants/essential oils contain natural antibiotics that kill gut flora and increase livestock productivity.
  • Resistance to essential oil antibiotic activity is slower, because of simultaneous use of multiple antibiotics.

Obesity is a Symptom of Antibiotic Damage to Gut Microbiome
Antibiotics make meat fatter
We may enjoy a fat marbled steak, but the corn and antibiotics used to produce that mouth-watering plate of satiety, is not so healthy.  Corn and antibiotics make that meat on the hoof fit for human consumption, but the cattle are quickly dying and the fat marbling is a symptom of cattle metabolic syndrome.  The corn and antibiotics disrupt the bovine gut microbiota and alter energy flow.  The result is prime beef. 

As It Is with Cattle, so It Is with Middle Americans
General descriptions of Americans with metabolic syndrome and steers ready for the abattoir are similar.  That should not be surprising, because both are caused by damaged gut microbiota and consequences of metabolic syndrome.  Americans routinely damage their gut microbiota with antibiotics (processed food, etc.) and the major symptoms of the resulting gut dysbiosis are chronic inflammation, depression, autoimmune diseases, obesity and metabolic syndrome.  Repairing gut microbiota reverses all of these symptoms. 

But Essential Oils Are Just Natural Antibiotics
Essential oils are natural antibiotics
Is it better to use essential oils than medical antibiotics to fatten cattle or treat Lyme disease or hospital infections such as C. diff.?  Most pharmaceuticals were derived from plants or fungi and were originally used to kill microorganisms, i.e. they were natural antibiotics.  We call these phytochemicals by a variety of names, e.g. antioxidants or essential oils, but they are more appropriately called phytoalexins, all natural, all plant, all toxic antibiotics.  It is entertaining that essential oils have had so many different traditional and pharmaceutical uses, and yet they have always been experienced by microorganisms (and our livers) as simply toxic.  Essential oils do have the significant advantage of being a mixture of antibiotics and might be very useful where pharmaceutical antibiotics have problems.  The toxicity of essential oils, especially toward gut bacteria, should not be ignored.

Resistance to Essential Oils as Antibiotics
Antibiotic resistance develops in sewage
I previously kept track of laboratory strains of bacteria by simply exposing large numbers of the bacteria to an antibiotic and selecting for the rare individual that had already spontaneous mutated (DNA replication error of one in a million).  We could then use the new drug resistant strain in experiments and identify it by its resistance.  The same thing happens to your gut bacteria with an overnight exposure to an antibiotic.  And of course it also occurs immediately in livestock exposed to antibiotics or in sewage plants where tons of antibiotics and gut bacteria are mixed.  Resistance to each of the chemicals in an essential oil also would rapidly occur, if bacteria were exposed to each alone and in a  toxic concentration.  This is repeatedly observed, since commonly used drugs are just individual components of essential oils that have been produced in large amounts in pills and marketed based on their predominant physiological activity, rather than just another antibiotic.  Thus, resistance to a statin or Metformin, as antibiotics, could be easily observed (even on multiple drug resistance plasmids), but is just ignored.

Essential Oils Are just Mixtures of Natural Antibiotics
Statins from fungal antibiotics
The impact of essential oils on gut microbiota is unpredictable, because the composition of essential oils is highly dynamic and so are gut microbiota.  Each component of an essential oil has a different spectrum of toxicities to hundreds of different target proteins to each of the hundreds of different species of bacteria in the human gut.  Ingested essential oils are modified by the detox enzymes of the intestine and liver.  The modified phytochemicals have different toxicities and act as additional antibiotics.  Mixtures of antibiotics, as in essential oils, less likely to select for resistance than individual antibiotics, but an antibiotic is still just an antibiotic, regardless of whether it is straight from the plant or via a pharmaceutical salesman. 

Common Medicines Are the Source of Superbugs

Common meds are antibiotics
Doctors with prescription pads and steers eating antibiotics are blamed, I think unjustly, for the crisis of antibiotic resistance.  The real culprit is you taking NSAIDs, statins, proton pump inhibitors, antidepressants and other common medicines.  Since they are all developed from plant antibiotics, they are still antibiotics, and they still select for antibiotic resistance.  It is important to remember that pharmaceuticals are repurposed natural antibiotics from plants.  The answer to the superbugs that are resistant to all of the common antibiotics is to dramatically reduce the use of all pharmaceuticals.  The initial goal should be a 90% reduction.  Costly pharmaceutical chemicals could be replaced with preventive diets and less disruptive manipulations of gut microbiota, e.g. ingestion of capsules containing freeze-dried gut flora.  This more gentle approach to health care would also provide huge cost savings, as well as vastly improving health.

Gut Flora, Disease and Obesity


The health of your gut flora (the interacting trillions of bacteria of a couple of hundred different species that make up the pound of bacteria that you carry primarily in your large intestines) is more important than your genetics to your overall health.  Thus, your health is a result of diet, gut flora adapted to your diet and exercise.  Everything else, your genetic risks, environmental toxins, etc. are of only minor impact.

I am trying to paint the big picture of how the food that you eat and your gut flora interact to determine your health, by which I mean whether you get sick, become obese and/or bloat with gas.

Health Depends on Gut Flora
If you are healthy, you have a couple of hundred different species of bacteria that help you to digest the protein, fats and carbs that you eat in meat and vegetables.  Your body easily digests protein and fats in meat, fish, eggs and dairy, because enzymes to digest them are present in your stomach and small intestines.  The only carbs that your body can digest are some simple sugars and starch.  The rest of the polysaccharides present in plants cannot be digested without the help of bacteria.  The polysaccharides that your gut flora can digest are fermentable, soluble fiber, e.g. resistant starch, pectin, inulin, arabinogalactan, xylans, beta-glucan, etc.  If you can’t digest soluble fiber, because you have damaged gut flora, dysbiosis, and are missing essential bacterial species normally found in a healthy gut, then the soluble fiber just passes through as insoluble fiber and readily dehydrates into hard, constipated stools.  Partial digestion due to just a few missing bacterial species produces the symptoms of food intolerances.  

Constipation Results from Dysbiosis
The bottom line is that the volume of healthy, soft, firm stools is made up of gut flora that digested dietary soluble fiber and converted it into more bacteria.  If you eat more soluble fiber, this food for your gut flora, will produce proportionately more bowel movements.

Gut Flora Guide Immune System Development
Most of cells of your immune system are in the lining of your gut and there are particular species of gut bacteria directly involved in the development of immune cells that have different functions as they spread throughout your body.  Some of these cells are aggressive and attack pathogens, while others make sure that the aggression doesn’t get out of control and cause autoimmune diseases or allergies.

Gut Flora Divided into Groups to Show Involvement in Disease
Recent studies have demonstrated the role of gut bacteria in producing nutrients, vitamins and neurotransmitters.  To highlight the essential role of gut flora in disease, I have divided the hundreds of species of gut bacteria into groups to illustrate their direct involvement in development of the immune system and regulation of the flow of dietary nutrients involved in obesity.  A recent study shows that an infection can produce a change in gut flora associated with marshaling additional fatty acid nutrients for the host instead of just producing more gut flora.  Chronic change of gut flora in this way leads to obesity.  Other types of dysbiosis contribute to infections, cancer, autoimmune disease, allergies, food intolerances, gas and bloating.

Group A Bacteria  Provide Aggressive Immunity
There are several dozen species of bacteria in healthy gut flora, including the filamentous bacteria, that trigger the development of the aggressive part of your immune system that attacks pathogens, and kills cells of your body that are infected with viruses or are cancerous.  Most antibiotics don’t permanently damage this group of bacteria, so after a course of antibiotics you can usually still stop infections.  Excessive suppression of aggressive immunity contributes to cancer.

Group B Bacteria Provide Suppressive Immunity
There are dozens of other species of bacteria, including Clostridia, that control the development of the suppressive half of your immune system that produces immune cells, such as regulatory T cells, Tregs, that stop the aggressive cells of your immune system from attacking your own cells and innocuous things such as food and pollen.  Many common antibiotics damage these species of bacteria and are thought to contribute to the development of autoimmune diseases and allergies.  Inflammatory bowel disease is characterized by a simplified gut flora with only half the healthy number of bacterial species.  Resistant starch preferentially feeds these bacteria to enhance suppressive immunity and in some individuals cure autoimmune disease.

Group C Bacteria Convert Soluble Fiber to Short Chain Fatty Acids (SCFA)
The fermentable soluble fiber in your diet is typically from vegetables and it is converted by the largest and most diverse group of bacterial species into short chain fatty acids.  Each different plant polysaccharide, and there are hundreds, requires many enzymes for complete digestion to the simple molecules used by the bacteria to make its own proteins, fats and polysaccharides.  Absence of bacteria that are specialized for the digestion of particular polysaccharides or other dietary components can disrupt gut flora and cause digestive disturbances that are experienced as food intolerances (also confused with food allergies that are rare.)  Some of the bacterial species convert polysaccharides into butyric acid and other short chain fatty acids that are the major source of energy for cells that form the lining of the intestines.  These SCFAs are also a major food source for other gut bacteria.

Group D Bacteria Convert SCFAs to Fecal Bacteria to Produce Bulk of Bowel Movements
In healthy people, the SCFAs produced by gut flora feed the intestines and the remainder produced in the large bowel is converted into more gut bacteria, which forms soft stools.  Antibiotics typically damage these bacteria and result in constipation.  These bacteria are typically more sensitive to antibiotics than those that digest the soluble fiber and produce SCFAs, so the excess SCFAs pass into the blood stream and contribute to obesity instead of stools.  Lean mice with gut flora exchanged from obese mice, become obese.  Cattle are fed antibiotics to enhance the conversion of corn polysaccharides into SCFAs and body fat prior to slaughter.

Group E Bacteria convert Soluble Fiber to Methane and Hydrogen, Bloat
Increased volume of the intestines, bloating, results from conversion of soluble fiber into methane, hydrogen and carbon dioxide gases.  Some of this gas is absorbed into the blood and can pass from the large intestines, through the blood, and back to the stomach and small intestines.  Helicobacter pylori, the cause of stomach ulcers and gastric cancer, can utilize hydrogen from the blood as an energy source.

In Summary:
A+B+C+D = healthy, normal weight
A+C+D = normal weight, autoimmunity and allergies
B+C+D = normal weight, susceptibility to cancer, chronic Lyme disease, food poisoning
A+B = normal weight, constipated
A+B+C = obese, constipated
A+B+D = normal weight, food intolerances
A+B+C+E = obese, constipated, bloated

Cure for Dysbiosis and Associated Diseases is Repair of Gut Flora
The excitement about the use of resistant starch (RS) and probiotics with Clostridia and other soil bacteria to reverse the symptoms of autoimmune diseases is based on the ability to repair gut flora damaged by poor nutrition and antibiotics.  Low carbohydrate diets that do not provide soluble fiber to feed gut flora lead to dysbiosis and chronic diseases.  Resistant starch, as the name suggests, passes on to the colon by avoiding digestion with amylases in the small intestines and acts as a soluble fiber to feed gut flora in the colon.  Clostridia convert the RS to sugars and SCFAs usable by other gut flora.  Note that some species of Clostridia produce toxins and it is these pathogens that take over in hospitals after the healthy species are killed off with antibiotics.  Fecal transplants are the best treatment for these hospital acquired infections. 

 I have discussed the role of hygiene, muddy veggies, fermented foods, etc. in several other posts on repair of gut flora.  

Complete repair of gut dysbiosis is possible, but it requires more than just changes in diet and dairy probiotics, as typically recommended erroneously by the medical industry.

Health is dependent on:
  1. an Anti-Inflammatory Diet,
  2. gut flora adapted to your diet
  3. exercise and
  4. adequate sleep
The rest (genetics, vegan vs. paleo, environmental toxins, organic veggies, GMOs, etc.) are minor contributors, less than 10% in aggregate, to overall health.

SweetMyx Taste Enhancers, Alapyridains?


---  Here are the other 200 blog posts ---
I was just reading announcements of new synthetic chemicals (SweetMyx) to enhance the taste and help reduce sugar and salt in "health foods".  The new taste enhancers have already been approved by industry organizations that designate the chemicals as GRAS, generally recognized as safe.  I, of course, was curious about how the SweetMyx chemicals made food taste sweeter with less added sugar.  Notice how convenient it is that the food industry has found a way to charge more for less sugar, just as labels have been changed to specifically designate "sugar added:".

Alapyridains are Taste Enhancers
I searched the chemical literature for new taste enhancers, since the chemical ingredients in SweetMyx are trade secrets and will not be disclosed on food labels.  It didn't take long to find that the likely suspects are called alapyridains.  This group of related chemicals are synthesized with a central pyridine ring familiar from the related cytosine and thymidine of nucleic acids, the plant alkaloid nicotine and the vitamin niacin.  A guanide group (half of the diabetes drug metformin, which is a biguanide) is added to make a salt enhancer, and a benzene ring is added to make a sugar enhancer.  Without these additions, the central structure inhibits the ability to taste the bitterness associated with "healthy plant antioxidants," phytochemicals and essential oils.

Will SweetMyx Just Tickle your Taste Buds?
The alapyridains that I expect to be in SweetMyx seem to be similar to common plant alkaloids, which are natural pesticides and antibiotics, i.e. phytoalexins.  So I would expect these compounds to also be antibiotics with unknown impact on our gut flora, nervous and immune systems, just like all of the medical antibiotics.  Based on the general putative structure of the taste enhancers and similarity to other molecules with known reactivities I would also expect these molecules to react with enzymes that bind sugars, e.g. glycosidases, or with hundreds of other proteins that bind to heparin, e.g. embryological growth factors, clotting factors, cytokines, amyloids, etc., etc., etc.  It would also be expected that these enhancers will encourage consumption without satiety and therefore, just as artificial sweeteners, contribute to further obesity.  In other words, these taste enhancers can be expected to have numerous, unpredictable medical and ecological side effects that will not be understood for decades.

Dr. Oz on Gut Flora Repair

---  the other 200 posts  ---
Where is the hippo? Trying to repair a complex community of a couple of hundred different species of bacteria by just changing diet, is like a zoo trying to add hippos by building a new enclosure and supplying it with fodder. You can wait and wait, but you can't add new species without adding new species. Hippos don't appear by spontaneous generation and neither does E. coli or other gut bacteria. You have to ship in hippos from other zoos and after antibiotic-induced extinction of gut bacteria, you have to introduce or eat missing species of bacteria. Also just adding probiotics will not provide a lasting fix for damaged gut flora any better than adding more elephants or giraffes will improve the diversity of a zoo lacking hippos.

I am amazed that Dr. Oz and the medical industry can encounter symptoms of dysfunctional gut flora, e.g. constipation, food intolerance, autoimmunity, allergy, that are preceded by antibiotic treatment and not address the compromised species diversity of the gut. The involvement of gut bacteria in immune system function is documented in the biomedical literature. The lasting impact of antibiotics on gut bacteria is known. Then why do Dr. Oz and the rest of the medical industry just recommend probiotics, a half dozen different species of bacteria found in fermenting dairy products (think elephants and giraffes), to repair a decimated gut bacterial community? They seem to be perplexed and ask, "Where is the hippo?"


Generalizations about Gut Bacteria
Each healthy human maintains a subset of a couple of hundred of the couple of thousand different species of bacteria found in humans around the globe. The diverse community in each individual may differ in species, but has approximately the same complement of genes in people sharing the same diet.
  • 1-200 different species of bacteria per person
  • 1-2000 different species of human gut bacteria
  • 1 million different genes among the different bacteria
  • Most genes are involved in digesting plant carbohydrates, i.e. soluble fiber: inulin, pectin, fructans, algal sulfated polysaccharides, etc.
  • Diet diversity, e.g. the Modern American Diet, reduces the diversity of the gut bacterial community, presumably because the rapid change in foods permits survival of only generalist bacteria that can digest many different foods.
  • Simple diets produce gut flora diversity, but only if there is access to diverse bacteria.
  • Health may result from diverse gut flora developed from a simplified diet and ample bacterial resources.
  • Obesity and other diseases may result from simplified gut flora developed from a changing, complex diet and a sterile environment/isolation.
  • Vegan and paleo extremes can lead to healthy gut flora diversity, if the gut bacterial community is permitted to adjust to the diet composition by avoiding rapid changes and providing diverse bacterial sources.
  • Meat contains complex polysaccharides, e.g. glycosaminoglycans, such as chondroitin sulfate and heparan sulfate proteoglycans, which are bacterial fodder equivalent to soluble fiber.
  • Probiotics are unique bacterial species that do not persist in the gut of adults, but dominate the gut of milk eating babies and stimulate development of the gut and immune system.
  • Probiotic bacteria can temporarily provide developmental signals for immune system development that are normally provided by a healthy gut flora.
  • Antibiotics cripple gut flora needed for development of the immune system.
  • Common medicines have significant antibiotic activity and modify gut flora.

Damage to Gut Flora is Not Repaired by Diet Alone
There is little or no effort being made by the medical industry to develop approaches to repair gut flora damaged by disease, unhealthy diets or medical procedures. This is similar to a surgeon stepping away from removal of a diseased organ without closing the wound. Antibiotics leave a gut flora that will remain permanently damaged without systematic, monitored repair. It might also be suspected that disruption of gut flora by antibiotics and the introduction of large amounts of new foods, such as high fructose corn syrup and vegetable oils may contribute to or cause the modern prominence of obesity. After all, gain or loss of weight changes gut flora, obese individuals have damaged gut flora, and trading gut flora between fat and lean animals, trades weight gain/loss behaviors.

Sources of Bacteria to Repair Damaged Gut Flora
  • We must eat new bacteria in order to replace bacterial species lost by antibiotics or unhealthy diets.
  • Probiotics -- bacteria that aide gut function, commercially from dairy fermentation
  • Fresh vegetables -- bacteria are on the surfaces of plants unless the vegetables are cleaned or cooked
  • Fermented foods -- Bacterial growth leading to acid or alcohol production has beed used in the preparation and storage of many foods and provides a rich bacterial resource.
  • Environment -- Bacteria are transferred to our hands and face from other people, pets and surfaces, unless hands and the body are continually washed. Sanitizers and frequent washing of hands and surfaces eliminate acquisition of environmental bacteria to repair damaged gut flora. Social isolation and hygiene block repair of gut flora.
  • Replacement -- experimental replacement of damaged with healthy gut flora (fecal transplant) has been very effective in curing many diseases without significant risks, but is restricted by the medical industry.

Dr. Oz on Sweeteners: Sugar, Fructose, Insulin/Resistance, AGE, FattyLiver



I was shocked when Dr. Oz recommended a snack made with agave syrup. I had seen a previous program by America's representative of the medical industry in which he revealed the hazards of agave syrup as a new source of fructose. Now he just skipped over the use of this fructose syrup as a "natural" sweetener, even though it is even less healthy than high fructose corn syrup, HFCS. There seems to be a lot of deliberate confusion about sweeteners and since I am trained as a carbohydrate chemist, I will try to tell it as I see it.

General Information 
  • Carbohydrates are not needed in your diet, since your liver can make all the blood sugar that you need from protein. Most diabetics can benefit from a low carbohydrate diet. 
  •  Glucose, the blood sugar, is primarily responsible for turning on insulin production, so sweeteners (glucose, sucrose, HFCS, corn syrup) or dietary carbohydrates (starch, e.g. cereal, rice, pasta, potatoes, bananas) that are readily converted to glucose, cause blood insulin levels to rise. 
  •  Fructose in any form (HFCS, sucrose, agave syrup) contributes to liver damage. Fructose is the most chemically reactive sugar. 
  •  Artificial sweeteners, especially in soft drinks, do not contribute dietary calories, but they apparently increase insulin production and contribute to hunger, eating and obesity. 
  •  Insulin production removes glucose from the blood, i.e. lowers blood sugar, by increasing glucose transport into fat cells. If glucose is in your blood, but insulin is not present, e.g. type I diabetes, then you get thin. If glucose is in your blood and insulin is present, then you get fat. If you are fat and glucose is still high in the blood and insulin is present, then the fat cells will die unless they shut off the insulin response, i.e. insulin resistance. Lowering the amount of carbohydrates, sweeteners/starch, in your diet makes it easier to control blood sugar levels and avoid hunger. 
  •  Decreasing dietary carbohydrates means that calories have to be present in some other form and the answer is saturated fat. Most polyunsaturated fats, e.g. vegetable oils, except olive oil, are not healthy. The fats in meat, butter, eggs and coconut oil are the healthy choices supported by the biomedical literature, and along with vegetables, form the foundation of a healthy, anti-inflammatory diet. 
Central Metabolism Started with Fructose not Glucose 
All organisms convert sugars through a common series of enzymatic steps, called central metabolism, to a simple, three-carbon compound called pyruvate. Pyruvate can be used as a source of energy in mitochondria in the presence of oxygen or converted into alcohol or acids in various forms of fermentation. No matter what sugars are used, e.g. glucose, galactose, mannose, they are all converted in cells into derivatives of fructose. Thus, fructose is common to all organisms and can be considered to be the most primitive. So why is glucose usually considered to be the the start of central metabolism and why is dietary fructose dangerous?

Fructose is too Reactive to Transport 
The first cells used fructose as the starting material to make the building block molecules of cells, e.g. carbs, proteins, fats, nucleic acids, and energy in the form of ATP. Multicellular organisms, such as animals and plants had to move sugars from cell to cell. It would be obvious to transport fructose, since all other molecules could be converted into fructose, but the problem is that fructose is too chemically reactive, i.e. it reacts with proteins to form AGE. It is for that reason that fructose is converted by cells into glucose, which is less than one tenth as chemically reactive. In plants, the reactive groups of glucose and fructose are bonded together to produce sucrose, table sugar, which is much less reactive and can be transported in plant vessels at very high concentrations.

High Blood Sugar is Bad, High Fructose is Worse (AGE-ing) 
High levels of blood sugar, glucose, react with proteins to produce advanced glycation end products, AGE. Fructose in the blood produces these inflammatory compounds more than ten times faster. That is why fructose is a bad sweetener for diabetics. Eating fructose, e.g. agave syrup or sucrose, doesn't directly raise blood sugar/glucose levels, since it raises blood fructose levels, which is worse.

Fructose Fattens Livers 
Fructose is rapidly absorbed in the intestines and transported to the liver. The blood vessels of the liver remove fructose from the blood and it is rapidly converted into fat. Fructose in sweeteners has now surpassed alcohol as the major source of liver disease.

Sweeteners
Fructose is ten times sweeter than glucose, and that is why cheap forms of glucose, such as corn syrup, are treated with enzymes to convert some of their glucose into fructose to produce high fructose corn syrup. Corn syrup is not as sweet as pure glucose, because the syrup contains a mixture of short chains of glucose of different lengths, and the chains decrease in sweetness with length. By changing some of the glucose into fructose, the HFCS can be made as sweet as table sugar, sucrose. Corn subsidies keep corn syrup cheap and make HFCS very profitable. Unfortunately, the HFCS contains fructose and therefore it has the liver toxicity and AGE-forming inflammation of fructose.  Agave syrup is like HFCS on steroids.

Agave Syrup is Fructose 
Agave syrup contains fructose produced by industrial processing of the fructose polysaccharides, inulin, in agave extracts. I cannot understand why anyone would use this commercially processed fructose as a sweetener. It doesn't raise blood sugar as much as sucrose, because there is much more fructose than sugar (like very high fructose corn syrup) it raises blood fructose levels instead, which is much, much worse.

Sugar Makes You Hungry 
The human body can only use simple sugars, e.g. glucose, fructose, sucrose, or starch. Body enzymes convert sucrose into fructose + glucose, and starch into glucose. Other carbs, such as soluble fiber, are only digested by gut bacteria in the colon. The conversion of starches to glucose begins with enzymes in saliva in the mouth and is completed in the upper part of the digestive tract. Starch should be considered as a simple sugar, because it causes a rapid rise in blood sugar, just like glucose. It may actually be faster than table sugar. The rapid rise of blood sugar causes a rapid increase in blood insulin, which in turn rapidly removes sugar into fat cells. The rapid rise and fall of blood sugar provides the experience of hunger. That is why cereal, e.g. oat meal, in the morning produces intense hunger just a few hours later. Actually, oat meal is not quite as unhealthy as most cereals, because it also has some soluble fiber to feed gut flora. A protein and fat breakfast, e.g. bacon and eggs, does not produce rapid hunger, because it does not produce a large insulin rise and glucose fall.

Insulin Resistance is Better than Death by Glucose 
As fat cells accumulate glucose as a result of blood sugar transported into the cells in response to insulin, more and more of the glucose is converted into fructose and on to pyruvate. The pyruvate accumulates in mitochondria and ATP production is saturated. This is potentially lethal for the cells, because the conversion of pyruvate into ATP is accomplished by removing high energy electrons as the pyruvate is converted to carbon dioxide. The high energy electrons accumulate in the inner membranes of the mitochondria and if they are not systematically converted to low energy electrons and dumped onto oxygen to produce water, reactive oxygen species, ROS are produced and the result is inflammatory oxidative stress. Antioxidants would be needed to protect from major cellular and organ damage. The cells protect themselves by responding to the accumulation of high energy electrons on the mitochondria by shutting down the response to insulin and blocking further intracellular glucose accumulation. This is insulin resistance.

Carbs: Never too Low 
Dietary carbs, such as sugars and starches are not needed, because the liver can convert protein into glucose. Thus, diabetics, who have a hard time balancing their dietary intake of carbs with the insulin that they inject, can simplify the process by routinely eating less carbs spread through many meals and triggering some glucose production by the liver. Craving for carbohydrates/sweets can be dramatically reduced simply by eating fewer carbs and avoiding insulin production that can lead to more dramatic swings of blood sugars and hunger. Using this strategy, I am hungry less than once a week.

Healthfulness of Sweeteners 
 --from Most Healthy....
  • Stevia - is a diterpene glycoside (I previously made the silly error of listing it as a protein) (erythritol, another simple sugar alcohol is added to make the stevia granular) that is sweet, doesn't raise blood sugar, no insulin spike and no AGE 
  • Glucose - raises blood sugar, spikes insulin and produces AGE 
  • Xylitol - is a sugar alcohol that inhibits dental bacteria, doesn't raise blood sugar, no insulin spike or AGE 
  • Corn Syrup - raises blood sugar, spikes insulin, produces AGE, low sweetness  
  • Sucrose - raises blood sugar, spikes insulin and produces AGE, and liver damage 
  • Honey - is half fructose and half glucose, raises blood sugar, spikes insulin, produces high AGE and may damage liver  
  • Artificial Sweeteners, aspartame, sucralose, saccharin, etc. - don't raise blood sugar or produce AGE, but may have other risks, including hunger 
  • HFCS - is high fructose corn syrup, raises blood sugar and spikes insulin, produces very high AGE and causes liver damage 
  • Fructose - doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage,  does not produce satiety and may encourage consumption of other sugars 
  • Agave Nectar - is mostly fructose, doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage

Is a Belly Bad?

A protruding midsection can mean many different things. It can be obesity, starvation/kwashiorkor or sarcopenia. It can mean there is a layer of fat outside, sagging organs poorly supported by weak abdominal muscles or fat surrounding the organs and stretching the muscles outward.

Alternatively having the same “lean” profile at 60 as at 16 could be a sign of a decline of muscle and an increase in fat surrounding organs. You can always have a porthole put in to see what is going on, or you can check the calendar and your C-reactive protein level.

If you are over fifty and your doctor has told you that your CRP, a measure of inflammation, is starting to creep up, then you are starting to suffer from age-related loss of muscle, sarcopenia. That is, you have begun to replace your muscle mass with fat, and the fat is producing inflammatory signal molecules, cytokines, that are the same as those produced by your immune system cells in response to an infection.

Most of the symptoms we associate with aging are just poorly managed chronic inflammation, as a result of replacing muscle with fat. The fat is metabolically lethargic, so you actually need less food, as your muscle mass declines. The result is that it is progressively easier to put pounds on. That is the bad news. The good news is that building muscle requires at least one of the inflammatory cytokines produced by fat, IL-6, so gaining muscle should be easier until you get back into shape. Losing weight is also anti-inflammatory, if the loss is fast enough to produce a fasting physiology.

All of the diseases associated with increasing age are just the accumulation of problems that result from increasing levels of chronic inflammation. Most of the increase is the result of inflammatory diet, but the increasing inflammation also decreases the desire to be physically active, with the result being a loss of muscle mass. Adjustment to an anti-inflammatory diet and lifestyle, can reverse the aging process.

It is also possible to be physically active and have a youthful muscle mass, but still have an inflammatory diet. The result will still be chronic inflammation, and cryptic inflammatory diseases that accumulate with time and produce sudden failures of joints, coronary arteries or cancer. Estrogens are also naturally anti-inflammatory, so women will find that menopause reveals any inflammatory diet/lifestyle that has been hormonally camouflaged. Thus, menopause may produce any of the typical signs of inflammation, e.g. acne, depression, back problems, arthritis, etc.

The bottom line is that a weak gut and/or extra body fat will cause problems at any age. And at any age, the diseases that are associated with inflammation can be minimized or avoided by an anti-inflammatory diet and lifestyle/exercise.

Inflammation Causes Disease

Human diets have changed dramatically over the last few hundred years, and as a consequence so have our diseases. The most recent shift in diet over the last hundred years has resulted in a shift from infectious diseases to degenerative diseases. This trend is summarized in the following Wikipedia entry.

Lifestyle diseases, from Wikipedia:

"Lifestyle diseases (also called diseases of longevity or diseases of civilization) are diseases that appear to increase in frequency as countries become more industrialized and people live longer. They include Alzheimer's disease, atherosclerosis, asthma, cancer, chronic liver disease or cirrhosis, Chronic Obstructive Pulmonary Disease, Type 2 diabetes, heart disease, nephritis or chronic renal failure, osteoporosis, acne, stroke, depression and obesity.

Death statistics in the United States
In 1900, the top three causes of death in the United States were pneumonia/influenza, tuberculosis, and diarrhea/enteritis. Communicable diseases accounted for about 60 percent of all deaths. In 1900, heart disease and cancer were ranked number four and eight respectively. Since the 1940s, the majority of deaths in the United States have resulted from heart disease, cancer, and other degenerative diseases. And, by the late 1990s, degenerative diseases accounted for more than 60 percent of all deaths.
Reference:
National Center for Health Statistics, National Office of Vital Statistics, 1947 for the year 1900 (page 67), for the year 1938 (page 55)."

My point here is that all of the so-called lifestyle diseases are also based on inflammation. I checked the research literature for studies of the response of each of these diseases to diets supplemented with omega-3 fish oils. Studies had been performed in each case. Reduction of inflammation by fish oil treatment was uniformly effective in reducing symptoms of all of the degenerative diseases. Other diseases that can be added to the inflammatory list are spinal disc problems and hypertension. It is interesting that disc dislocations are associated with coeliac, an inflammatory/autoimmune disease. It is also interesting that acne and depression are listed. Acne is indirectly associated with diet, but if sufferers shift to an anti-inflammatory diet, acne symptoms disappear. Depression associated with childbirth is particularly responsive to anti-inflammatory drugs, diet and exercise. Most of the symptoms associated with aging are just due to inflammation and are similarly responsive to anti-inflammatory lifestyle changes

To summarize:
  • Modern degenerative diseases are caused by modern inflammatory diets (and insufficient exercise.)
  • Anti-inflammatory diet and lifestyle reduce degenerative diseases.
  • Aging is predominantly mismanaged inflammation.

More Inconvenient Truths

I am writing this shouting summary of bottom lines in response to recent good news and bad news. The good news is that Michael Pollan is speaking in Boise, near my home town. The bad news is the recent press coverage of the JUPITER study on statins.

Michael Pollan is one of my heros. He speaks simply and clearly about the role of national agriculture policy in promotion of hazardous foods that lead to profits in the healthcare industry, but death and disease for the US population. Pollan also provides wise advice to solve our problems.

A new statin, Crestor, was shown in the JUPITER study to significantly reduce the risk of cardiovascular events, e.g. heart attacks, stroke, death, in a study population with normal LDL and elevated C-reactive protein, an indicator of inflammation. The press supported the drug maker’s interpretation that the statin provided benefit by lowering LDL in a population with chronic inflammation. What is missing is the clarification that lowering LDL is unimportant in reducing cardiovascular risk. Lowering inflammation lowers cardiovascular risk and there are more appropriate ways of lowering inflammation than using very expensive drugs. It is much cheaper, healthier and effective to switch to an anti-inflammatory diet and lifestyle!

After reading thousands of articles in the biomedical research literature, here are a few of my obvious bottom lines. Diet affects your health and the most fragile stages of development and most fragile organs, are the most sensitive to abuse. Therefore, damaging diets are most harmful to fetuses, newborns, brains, the cardiovascular system and reproductive systems.

  • Formula promotes inflammatory bacteria in newborn guts resulting in lower intelligence, disrupted immunity, infections, allergies, obesity, degenerative diseases and autoimmune diseases. Breastfeeding is the only anti-inflammatory answer for infants.
  • The US diet (hyperglycemic starch/sugar, high omega-6 to omega-3 fatty acid ratio, HFCS, low vegetable anti-oxidants, low vitamin D/sun exposure, low vitamin C, grain-fed meat instead of fish) is inflammatory.
  • The Mediterranean Diet (small portions of starch, low omega-6 oils, no HFCS, high vegetable anti-oxidants, routine sun exposure, adequate vitamin C, fish and grass-fed meat) is anti-inflammatory.
  • Inflammatory diets lead to infertility (female and male), problems during pregnancy (e.g. preeclampsia is an omega-3 fatty acid deficiency) and prematurity/low birth weight.
  • Mental illnesses of many different types benefit from anti-inflammatory diet and lifestyle. Diet-based brain inflammation may be a major predisposing factor.
  • All of the prevailing drug therapies for cardiovascular disease benefit from anti-inflammatory diet and lifestyle. Most of the drugs that reduce cardiovascular events rely on anti-inflammatory activities. Inflammation is the primary cause of cardiovascular disease, not elevated blood lipids/cholesterol.
  • Vegetable oils (corn, soy, cottonseed, safflower) are rich in omega-6 fatty acids and are dangerously inflammatory. These polyunsaturated oils are less healthy than saturated fats. Olive oil is the most healthy.
  • Reasonable routine exposure to the sun could eliminate inflammatory vitamin D deficiencies.
  • Obesity is inflammatory, but diet-based inflammation may also be a major contributor to obesity.
  • Genetic predisposition to specific diseases is triggered by diet-based chronic inflammation.
  • Diseases and disabilities associated with aging are symptoms of mismanaged chronic inflammation typically resulting from decreasing muscle mass and increasing fat.
  • Sensible diet and lifestyles could dramatically improve quality of life and reduce healthcare expenditures in the US.

Prescription: eliminate vegetable oils, eliminate HFCS, eliminate trans fats, use olive oil, reduce starch, eat vegetables, eat more fish and less meat, get daily sun, use fish oil supplements, get frequent muscle-building exercise, and stay lean.

Inflammation Score

Most people need some feedback to monitor the impact of their diet and exercise on their health. I tried to point out some of the major contributors to chronic inflammation with a little check list. See how you score (choose one of the list for each category) and give me your feedback on the how you think each part contributes to inflammatory diseases.

Fat Content ____
lean 0
extra abdominal fat 4
obese 8

Carbs ____
small meals, no cereal for breakfast 0
fistful of starch with each meal 2
pasta/rice/potato as a meal 4

HFCS ____
high fructose corn syrup banned from your diet 0
don’t avoid HFCS, but avoid soft drinks 2
have replaced sucrose with HFCS, enjoy soft drinks 4

Unsaturated Fats ____
have removed vegetable oils (except olive oil) from your kitchen 0
use canola oil 2
have replaced saturated fats with corn oil 4

Trans fats ____
eat no trans fats 0
avoid trans fats on your chips 2
don’t know what trans fats are 4

Fish oil ____
supplement with two or more fish oil (DHA/EPA) capsules per day 0
eat at least two helpings of oily fish per week 2
avoid all fish products 4

Antioxidants ____
know that coffee, tea and chocolate are good sources of vegetable antioxidants 0
eat five servings of fruits and veggies 0
take vitamin C supplement, because you avoid veggies 2
avoid veggies; meat and potatoes type 4

Exercise ____
take a stroll after meals and maintain your muscle mass 0
run when you feel guilty 2
couch potato 4

If you smoke, add an extra 15 points

Add ‘em up. How much are you stoking the inflammation furnace?
0-5 Cool! You will never look your age.
6-10 You are getting warm. Hope that you don't have any genetic predispositions to disease.
11-15 You may postpone inflammatory illness until middle age. The flame is lit. Pick your disease.
16-25 If you aren’t showing a chronic disease, you will soon.
26+ You can reverse your disease symptoms with the inflammatory diet and exercise.
