An interesting article was published last September in the Canadian Journal of Gastroenterology, in which the author hypothesized that sucralose (brand name Splenda) might be the cause of inflammatory bowel disease (IBD). The disease emerged in the past century, and was most prevalent in Western countries like the United Kingdom, the United States, and in northern Europe. Interestingly, prevalence of IBD in Canada was much lower, until recently.

In recent years Canada has become a country with the highest incidence of IBD. The author, who, a decade ago, found that certain dietary chemicals, like saccharine, inhibited gut bacteria, thereby deactivating digestive enzymes, possibly causing IBD due to the increased damage to the intestinal lining. In Canada, the use of saccharine was more restricted than in other Western countries, which could explain why Canada did not have higher IBD rates when other Western countries did.

The author suggests that sucralose, which has been widely used in Canada since the 1990s, may be an even more potent contributor to gut bacteria inhibition, thereby leading to IBD, and explaining the newly increased rates of IBD in Canada. The author states that sucralose “may have a more pronounced effect on gut bacteria than saccharine in that approximately 65 to 95 percent of sucralose is excreted through feces unchanged, while a large proportion of saccharine is absorbed and excreted through urine.” This means that higher amounts of sucralose come into contact with the intestinal lining.

There are no studies yet on the link between sucralose and IBD, but the author calls for it. I find this to be an interesting link. Studies have shown that sucralose alters gut bacterial balance, and altered gut bacterial balance is a hallmark of IBD. I always recommend avoiding artificial sweeteners. Here is yet another good reason for it.

A new study, published in the European Journal of Clinical Nutrition, demonstrated a connection between diet, and stool pH and bacterial levels in adults.¹ The researchers studied stool samples from vegetarians, vegans, and omnivores. They found lower levels of potentially pathogenic bacteria, like E. coli, in people consuming the vegan or vegetarian diets. What they also found, in conjunction, was a decrease in stool pH level with decreases in consumption of animal proteins. Those on the omnivore diet had a stool pH of 6.9; those on the vegetarian diet (which included dairy and eggs) had a stool pH of 6.6; and those on a vegan diet (no animal proteins) had a stool pH of 6.3.

The higher pH in the omnivore diet is explained in part by an increase in the production of alkaline metabolites by enhanced growth of the protein-digesting putrefactive bacteria in the gut. That’s right—a diet high in animal protein promotes increased putrefying activity of gut bacteria, raising the pH of stool and making products like putracene, cadaverine, and nitrosamine, which could lead to colon cancer. Diets lower in animal protein and—this is key—higher in fiber promote gut bacterial activity that produces more acid via production of the beneficial short-chain fatty acids (SCFAs) butyrate, propionate, and acetate, promoting a more acidic environment in the gut.

The change in pH levels explains why potentially pathogenic bacteria were increased in the higher pH (more alkaline) stools of people consuming an omnivorous diet. Lower pH ranges do not support the growth of potential pathogens, which thrive in the higher pH range over 6.5.^2,3 So I say, stay alive under 6.5!  

Here is a major point. The lower pH may be mainly a biomarker indicating the production of the SCFAs, particularly butyrate. Butyrate is a major fuel for the colonocytes, and is critical for optimum colon health. Butyrate also affects nuclear transcription in a positive way. In other words, when colonic cells are under attack from absorption of free radicals from fecal material (more likely to happen with chronic constipation), the nucleus, under stress, sends a message to the cell: either commit suicide (apoptosis) or produce more damaged cells (cancer).  Butyrate is more likely to promote apoptosis, preventing cancerous cells and allowing new cells to come in and maintain a healthy colon lining.

However, we must always remember everything is a question of balance.  All of the SCFAs including butyrate come from the fermentation of soluble fiber from plants by commensal bacteria. Too much fermentation with too low of a pH (or too much acid) can damage the colonic lining creating increased permeability problems leading to numerous problems including immune imbalances which can have total body effects.

The researchers also found a decrease in levels of Bifidobacteria and Bacteroides in the people on a vegan diet. This is in contrast to other studies that have found increases in Bifidobacteria, and seems an anomalous finding, since high-fiber diets support the growth of Bifidobacteria, while suppressing the growth of potential pathogens. Perhaps a closer look at the diets would be in order. Many vegetarians and vegans eat high amounts of refined carbohydrates, and too much fats and oils which do not promote healthy Bifidobacteria levels.

The researchers state, “In addition to age, gender and diet, factors such as microbial interaction, food transit through different intestinal compartments with different bacterial colonization density, availability of nutrients, colonic supply, sulphate and bile acids, and bacterial adaptation may all be involved in the composition and activity of colonic microflora. This may help in understanding the lower abundance of Bifidobacteria and Bacteroides species in vegans and vegetarians, which was not linked to stool pH.”

At any rate, all diets—vegan, vegetarian, and omnivore—will benefit by adding probiotic-rich foods along with supplements to help replenish levels of the beneficial Bifidobacteria and Lactobacilli. These bacteria, along with a high-fiber diet high in vegetables and fruits, help to lower the pH in the intestines by producing the nourishing SCFAs.

Incidentally, this topic can confuse the message of the benefits of a high-alkaline diet. You may have heard that a diet high in animal protein, sugar, and refined carbohydrates creates acidity in the body. Yes, these foods do lower urine and salivary pH levels, which are thought to be associated with bone mineralization, a process that helps neutralize acidity by pulling alkaline minerals from bone.  Chronic low grade acidity (metabolic acidosis) also causes excess loss of calcium, magnesium and potassium in the urine. Diets high in vegetables and fruits, on the other hand, produce more alkaline urine and saliva levels, which is associated with reduced bone loss and reduced loss of minerals in the urine.⁴ These variabilities in optimum pH in different areas show the body’s ability to change based on local environment and physiologic and biochemical requirements.

The bottom line is, healthy pH levels, whether in the colon or systemic, are found when you eat a high-fiber diet, high in vegetables and fruits, healthy proteins, and healthy fats. Complement this with foods and supplements high in beneficial bacteria, omega-3 fatty acids, and digestive enzymes, and you will be supporting optimal health (which begins in the digestive system).

A team of researchers at Mayo Clinic recently uncovered an interesting physician bias regarding the diagnosis of the upper digestive conditions gastroesophageal reflux disease (GERD) and functional dyspepsia (also known as indigestion). The two conditions can overlap, but each condition has its own distinct symptoms.

The researchers uncovered a bias on the part of physicians who diagnosed the two conditions. Although the number of GERD diagnoses has increased in the last 20 years, the reported GERD symptoms have decreased. When symptoms of both conditions are present, the most common diagnosis is GERD. Further, when only symptoms of functional dyspepsia are present, diagnosis of GERD is still more likely.

I believe this is due to the influence of the pharmaceutical industry over doctors when it comes to treating upper GI conditions with proton-pump inhibitors (PPIs), among the most commonly prescribed drugs today. Proton pump inhibitors were first used to treat peptic ulcers until it was discovered that peptic ulcers are not the result of too much stomach acid, but instead the result of infection with a bacterium known as Helicobacter pylori. Without a condition to treat, the focus of these drugs was turned to heartburn. Thus began widespread belief that heartburn was simply the result of too much stomach acid. To the rescue: Proton pump inhibitors and acid blockers.

As the Mayo Clinic study shows, functional dyspepsia is also now transitioning into a category in which proton pump inhibitors come to the rescue. But PPIs are not FDA approved to treat functional dyspepsia. Instead, doctors are seeing its symptoms—incomplete digestion, bloating, belching, excessive fullness, delayed stomach emptying—as those of GERD, a condition for which they have a well-known drug to treat it with.

The findings of this study are not surprising. The pharmaceutical companies have a lot of influence—on us (who hasn’t seen a pharmaceutical commercial or magazine ad lately), and on physicians (many of whose pockets are lined by these companies, in one way or another). Fortunately, when it comes to digestion, there are many dietary and lifestyle changes that can be made to improve the condition. If you are dealing with these conditions, or trying to avoid them, educate yourself!

It is true that functional dyspepsia can be difficult to treat. I have found that digestive enzymes are very helpful with easing the symptoms associated with this condition, which often result from poor diet, poor eating habits, and insufficient digestive enzyme production, all of which can be helped by digestive enzymes.

Alzheimer disease is the most common form of dementia, accounting for 50 to 80 percent of all dementia cases. Dementia involves memory loss and other impaired intellectual abilities, all of which interfere with everyday life. Though most people with Alzheimer disease are over 65 years, up to five percent have early-onset Alzheimer’s, which usually appears during the mid-40s or 50s.

Beta-amyloid is a peptide found in plaques in the brains of people with Alzheimer disease. For a long time, it has been thought that beta amyloid-played a causative role in the neural degeneration of the disease. This may be a mistaken belief, however, as highlighted by a recent Phase III clinical trial on the anti-amyloid drug semagacestat. Patients in this trial were expected to improve on this drug, which interferes with the production of gamma-secretase, the enzyme that produces beta-amyloid. Instead, the drug “did not slow disease progression and was associated with worsening of clinical measures of cognitions and the ability to perform activities of daily living,” according to a press release put out by the drug manufacturer, pharmaceutical giant Eli Lilly. The trial was stopped before completion.

As it turns out, beta-amyloid is an antimicrobial peptide, and is suggested to be secreted by the brain in self-defense against infectious pathogens, as David Perlmutter, M.D. stated at the Institute for Functional Medicine’s 20^th Symposium this past summer. We know beta-amyloid plaque builds up in the brain in people with Alzheimer disease, but what if its presence was a self-defense mechanism rather than the actual root cause of Alzheimer’s?

In a recent study by researchers at Mass General Institute for Neurodegenerative Disease, we may have our answer. The researchers stated, “Rather than beta-amyloid acting as a sole independent initiator of neuroinflammation, our data raise the possibility that the peptide may be part of a response mounted by the innate immune system. An absence of the peptide may result in increased vulnerability to infection.”¹

Two main pathogens are implicated as possible triggers of Alzheimer disease: Herpes simplex virus 1, the virus known for causing cold sores of the mouth, and found in about 90 percent of all adults; and Chlamydia pneumonia, the respiratory bacteria known to cause pneumonia.

In one study, the presence of anti-HSV IgM antibodies was found to be an even bigger risk factor for the development of Alzheimer disease than even the “Alzheimer’s gene” APOE4 allele.² In describing how Herpes may lead to Alzheimer’s, the researchers state, “Recurrent reactivation of HSV might act as a potent stimulus to the brain microglia, increasing the level of cytokines and initiating a positive feedback cycle that gives rise to an increasing accumulation of pathological changes.”

DNA from HSV1 and from Chlamydia pneumoniae has been found in the brains of people with Alzheimer disease.^3,4 HSV1 was found in specific areas affected by Alzheimer’s, and Chlamydia was actually cultured from brain samples taken from recently-deceased Alzheimer’s patients, indicating the virus was alive in the brain.

Chlamydia pneumonia is also known as the “heart attack” bacteria, found in the intraclavicular space/fluid between gums and teeth. The best prevention for this, incidentally, is the use of Plaquers dental floss; dental floss with a handle. When the bacterium is found, orthodontal work should be performed. People with high levels of hs C-reactive protein (a marker of inflammation in the body) are at particular risk for mouth infection with C. pneumoniae bacteria. C. pneumoniae is associated with heart disease because it is also commonly found in the soft plaques of people who die of acute heart attack.

Dr. Perlmutter recommends L-lysine and vitamin D3 supplementation, in addition to a diet high in lysine, which includes whole grains, fruits, vegetables, cheese, yoghurt and fish, and is low in tofu and other soy foods high in arginine. It is thought that activation of the virus, as with cold sore outbreaks, is a sign the virus might be active in other areas, like the brain. Preventing this may be helpful for people with Alzheimer’s.

So, why do people get infections in the first place, and why do these infections get activated? Well, lack of vitamin D, which is more common than most people realize, and uncontrolled blood sugar levels and insulin resistance, both triggered by a diet high in refined carbohydrates and sugar, are factors which affect both cellular and adaptive immunity, making us more prone to viral and bacterial infections.

It is important to note that there is much more to this story than infections. Alzheimer disease is a multifactorial “perfect storm” of triggers—usually inflammatory triggers—that interact and overlap, creating the final neurodegeneration of Alzheimer’s. Infectious triggers are just one small piece to this puzzle. For general protection against Alzheimer’s, remove sugar from the diet, reduce saturated fat intake, and incorporate vitamin D, omega-3 fish oil, pre- and probiotics, fiber and digestive enzymes. Be sure to sleep well, eliminate regularly, get plenty of exercise and be happy.

The immune system is a complex organization of coordinated responses to “foreign” invaders in the body. Foreign invaders include microbes—bacteria, fungus, parasites and viruses—as well as toxins and even food. As a matter of fact, one major role of the immune system is to not respond to food. As is seen with food allergies, however, the immune system is not always successful at this. Food allergies involve an overactive immune response to certain foods, which would normally be recognized as harmless. 

The immune system is comprised of two main branches: the innate immune system and the adaptive immune system. The innate immune system, also known as cell-mediated immunity, involves an immediate non-specific immune response, often against pathogens. The adaptive immune system, also called humoral immunity, involves a delayed, specific, organized response involving the production of antibodies that later recognize invading microbes so that a more effective immune response can be mounted. The innate immune system involves the production of cells called T helper 1 (Th1) cells, and adaptive immunity involves the production T helper 2 (Th2) cells. T helper cells are lymphocytes, a type of white blood cell. They are like the messengers of the immune system, sending signals that stimulate various immune responses.

Th1 and Th2 responses are joined by another type of T helper cell known as Th17. Th17 and Th1 responses are both associated with over-active immune responses, as is seen in autoimmune conditions, in which the body mistakenly attacks its own tissues. Both these responses produce inflammation by way of cytokines, the immune equivalent of hormones. These three types of T helper cells are all regulated and balanced by cells known as T regulatory cells, or Tregs.¹

Are you confused yet? Think of all these T cells as a four-way seesaw.  Th1 and Th17 are on two prongs of one end, and Th2 and Tregs are on two prongs of the other. When all is well, this seesaw is in balance, like a harmonized symphony responding appropriately to that which the body comes into contact.  If out of balance, you may see higher levels of Th1 and Th17, an indication of underlying autoimmunity as is seen with type 1 diabetes, celiac disease, rheumatoid arthritis, psoriasis, multiple sclerosis and systemic lupus erythematous. In contrast, higher levels of Th2 and Tregs are characteristic of allergic conditions like asthma, food allergies and hay fever, and with immune suppression.

How can we balance immunity? Well, probiotics are one solution. Since over 70 percent of the immune system is in the gut, probiotics are in the right terrain for immune system communication. Probiotics help balance immune response.  Gut bacteria essentially “prime” the immune system,² educating it so that it responds appropriately to what passes through the digestive tract—and to what may ultimately pass through the small intestine and into the body.

Omega-3 fatty acids also affect immunity, largely by helping to balance the inflammatory response—an important aspect of immunity. You see, inflammation is a necessary physiologic occurrence.  But too much inflammation spells trouble.  The omega-3 fatty acids EPA and DHA found in fish oil help to quell inflammation at the right time.  They help stimulate the production of resolvins, chemicals knows to help “resolve” inflammation—or end it at the appropriate time.³ 

Further, the proper digestion of food is necessary so the immune system doesn’t have to work too hard.  When food is not broken down properly, undigested food particles can aggravate the gut, causing inflammation and even leaking through a permeable intestine (also known as leaky gut) and entering circulation where yet more inflammation is triggered, in a downward spiral of excess inflammation (which is at the basis of most, if not all, chronic disease).

Also important is regular bowel elimination, which can be attained by the consumption of dietary fiber—at least 35 grams per day. A diet rich in fruits, vegetables and whole grains is essential, and a fiber supplement can help reach 35 grams, which can be difficult to obtain through diet alone.

In essence, the HOPE Formula—High-fiber, Omega Oils, Probiotics and digestive Enzymes—can help improve digestive health and improve immune balance. Brenda and I have been recommending this formula for years for many good reasons. With the HOPE Formula, there is hope that your health will improve.

A recent study published in the journal PLoS Biology has found that Candida albicans forms two distinct biofilm types according to what form the Candida is in—the sexual or asexual form.¹ A biofilm is a protective polysaccharide matrix in which microbial populations exist and are able to hide from the immune system and antimicrobials. As it turns out, when Candida is in an asexual form, it produces a biofilm that is impermeable to antifungals, antibodies and white blood cells. This asexual form makes up the majority—about 90 percent—of Candida cells in the body. The other ten percent are sexually reproducing Candida cells that form a similar looking biofilm that behaves differently and is susceptible to antifungals and to the immune system.

Biofilms are formed by more than just Candida, however. The National Institutes of Health (NIH) estimates that nearly 80 percent of chronic microbial infections are due to biofilms.² Dr. Maria Usman, MD has developed, and is refining, a Biofilm Protocol for use in children with gut disorders on the autism spectrum.³ She is seeing some success with this protocol, though it must be tailored to the individual and can cause a “die-off” reaction, also known as the Herxheimer reaction. (When microbes are killed they give off microbial toxins that can cause sickness-like symptoms that can make the patient feel worse before getting better.)

Another approach that can help get Candida and gut issues under control is the 4R Model.⁴ The Institute of Functional Medicine promotes this model as the best way to evaluate and treat patients with gastrointestinal complaints. The 4R model asks four main questions:

REMOVE—What may need to be removed? This may be pathogenic or potentially pathogenic organisms like Candida, bacteria or parasites. It can also be foods or toxins to which the person is sensitive or allergic.

REPLACE—What may need to be replaced? In this step, the use of digestive enzymes and HCl should be considered to ensure that they body is properly absorbing necessary nutrients.

REINOCULATE—What may the body need to be reinoculated with? This considers intestinal microbes and uses probiotics and prebiotics to reestablish intestinal balance.

REPAIR—What may be needed to repair a healthy mucosal layer? The use of certain nutrients, such as L-glutamine, to repair the mucosal layer are useful here. 

One probiotic—the probiotic yeast Saccharomyces boulardii—may be particularly helpful for those with Candida problems. Candida often occurs in people who have been treated with antibiotics. Antibiotics target bacteria, both good and bad, but do not affect Candida because it is a yeast, leaving no competition for Candida. This is where S. boulardii can be helpful, because it is not killed by antibiotics like other probiotic bacteria. Futher, S. boulardii has also been shown to inhibit Candida albicans.⁵ S. boulardii produces capric acid, and both have been shown to downregulate (reduce) the expression of genes associated with Candida virulence. Thus, the capric acid secreted by S. boulardii inhibits C. albicans hyphal formation, adhesion properties and biofilm formation.⁶ Probiotic bacteria have also been found to be helpful for Candida by helping to reduce and inhibit Candida, and by stimulating immune response against Candida.⁷ 

Bringing the gut back into balance takes a multipronged approach.  The 4R program can help address the multiple issues that arise when faced with digestive conditions like Candida overgrowth.

Autism is a developmental disorder characterized by severe abnormalities in communication, social awareness and skills, and behavior. Before the 1980s, autism occurred in 2 to 5 of every 10,000 children. Today about 1 in every 110 children gets autism. This rapid increase cannot only be attributed to improved diagnosis, and also indicates there is more to the disorder than simply genetics. Indeed, autism is a combination of genetic predisposition with environmental factors that triggers its development.

One aspect of contributing factors, at least in a subset of children, involves gut dysfunction. Many reports describe gastrointestinal symptoms and abnormalities in up to 84% of children with autism.[1] From constipation, diarrhea, abdominal discomfort, food sensitivities and abnormal gut flora to immune dysfunction and gut and systemic inflammation, the digestive system plays a central role in many cases of autism.

One gut abnormality—lactose intolerance—found in people with autism was recently reported in the journal Autism. Intestinal disaccharidase activity was measured in 199 individuals with autism. Disaccharidase is an enzyme that breaks larger sugars (disaccharides) like lactose, maltose and sucrose into smaller sugars like glucose. Deficiency of lactase enzyme, the enzyme that breaks milk sugar, or lactose, into galactose and fructose, was found in 58 percent of autistic children and 65 percent of autistic adults. In children, boys under 5-years-old had 1.7-fold lower lactase activity than girls of the same age, indicating the problem may be more severe in boys. The study concluded that lactase deficiency is common in autistic children and may contribute to abdominal discomfort, pain and the observed abnormal behavior seen in autism. Further, the study points out that most autistic children with lactose intolerance are not identified when doctors take a clinical history.

A decrease in activity of a variety of carbohydrate-digesting enzymes has been reported in children with autism.[2] Carbohydrase and disaccharidase enzyme deficiency results in the incomplete breakdown of carbohydrates in the small intestine. These partially undigested carbs move into the colon where they are greeted by a large supply of “hungry” bacteria—including potentially pathogenic bacteria. This may explain the increased presence of Candida and Clostridia species found in the guts of autistics.[3][4]

Carbohydrate-digesting enzymes are not the only digestive enzymes that may cause problems in autism. Fat malabsorption is seen in some autistic children, resulting in fatty, loose, floating, foul-smelling stools, also known as steatorrhea. Further, a particular enzyme known as dipeptidyl peptidase-4 (DPP4) may be deficient in those with autism. This enzyme breaks a specific peptide bond in gluten and casein proteins. In fact, it is thought that a deficiency in this enzyme is responsible for the incomplete breakdown of casein and gluten peptides (known as gluteomorphins and casomorphins) that act as opioids in the central nervous system and are thought to contribute to autistic symptoms. Following a gluten-free and casein-free diet has been found helpful in many autistics because it eliminates exposure to these peptides, often relieving symptoms. Supplemental DPP4 can be given in cases where accidental ingestion of gluten- or casein-containing foods is suspected, but it is not recommended as a replacement for the gluten-free, casein-free diet.

In all, we see a variety of enzyme deficiencies in autism and it would be wise to supplement with a digestive enzyme formula that includes a variety of enzymes. Further, due to the many digestive abnormalities seen in autism, the HOPE Formula (High-fiber, Omega oils, Probiotics and digestive Enzymes) is a wise daily maintenance program to support gut health.

A recent study to be published in the journal Pediatrics found that the prevalence of food allergy in children is higher than previously thought.¹ It turns out that 8 percent of children—that’s about 1 in every 13 children—are affected by food allergy. Food allergies and sensitivities are far-reaching problems contributing to many autoimmune conditions like type 1 diabetes, arthritis and psoriasis, and to neuro-inflammatory conditions like autism and attention-deficit/hyperactivity disorder (ADHD).^2-5

Food allergies and sensitivities are essentially the result of a breakdown in gut mucosal immune regulation in response to food antigens that pass through the gut. The gut-associated lymphoid tissue (GALT) makes up about 80 percent of the body’s immune system, and it resides in and around the gut. The job of the immune system in the gut is to respond to foreign invaders, like pathogens, by destroying them. At the same time, it must also not respond to the large amount of food that passes through the gut every day—this is known as oral tolerance.

When it comes to food allergies and sensitivities, building and maintaining a healthy gut lining is key. The HOPE Formula can help you to achieve this with High fiber, Omega oils, Probiotics and digestive Enzymes.   

If you have the right bacterial balance, as can be achieved with probiotics, the gut lining will be minimally inflamed and therefore minimal leakage of microbial toxins will be available to activate the GALT. The beneficial bacteria also create more of an immune tolerance with the epithelial cells that line the intestine—especially the mucosal-associated lymphocytes that are part of the epithelial lining.⁶

The right balance of soluble fiber and insoluble fiber can also minimize allergies—the soluble fiber by producing beneficial short chain fatty acids, especially butyrate, which is the primary fuel of the colonocytes; and insoluble fiber by diluting out any toxins associated with allergens that are exposed to the intestinal lining. In addition, it holds water and bulks the stools to promote better and quicker elimination, thus reducing the time of exposure to allergens.

The essential omega-3 and omega-6 oils in the right ratio promote immune balance in the gut lining and gut-associated immune system. Most people consume too many omega-6 oils and too few anti-inflammatory omega-3 oils. Omega-3 supplements can help reverse this imbalance. Digestive enzymes help by effectively breaking down proteins, fats, and carbs into less-antigenic food particles so that the intestinal (epithelial) lining does not react in an allergic, immunologic manner.  

HOPE should be a foundational health concept to help eliminate and/or prevent food allergies, especially when combined with avoidance of known allergenic foods and a rotation diet that avoids repetition of any given sensitive food for at least 3 to 4 days before eating it again.

There is still a general belief with medical doctors and the public as well that Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) are mostly stress-related psychological disorders. I have personally had many patients who were reluctant to discuss their bowel problems for fear of being labeled a “psych” case. Many practitioners still aren’t aware there can be legitimate causes of disease that come from both mind and body.

With IBS and IBD, as with most discussions, there is often an element of truth on both sides or there would be no controversy. First, let’s look at the validity of the stress factors. People with genetic short serotonin transporter systems react negatively to stress-related increases in cortisol (a stress hormone) than people with normal serotonin transport systems.1 Second, ALL people react to significant stress, which can produce damage to the gut epithelial lining. However, people with a history of IBD generally show more gut lining damage than those without IBD. The damage includes: increased levels of stress hormones, activation and degranulation of mast cells, mitochondrial damage in epithelial cells, and mucosal protein oxidation which can create multiple problems with permeability (leaky gut) and immunity.2 Again, this happens to everyone under stress, but is worse with IBS and IBD because stress can trigger a relapse of either condition.

On the other hand, there are many reports that suggest anywhere from 20 to 60 percent of IBS and IBD patients have had a serious gastrointestinal infection days or weeks before they began having symptoms of chronic bloating, abdominal pain, diarrhea or constipation (or both diarrhea and constipation) that may have lasted years. A study was done on 111 patients with IBS using the lactulose breath test (measures hydrogen and methane gas produced by too many of the wrong bacteria) and 84 percent of patients were positive, which indicates small intestinal bacterial overgrowth (SIBO). Those who were treated with a non-absorbable antibiotic, Neomycin, had a statistically significant improvement both in symptoms, and normalization of the breath test.3 A more recent study4 showed that patients with IBS, but without constipation, treated with rifaximin (a broad spectrum non-absorbable antibiotic) for two weeks provided significant relief of IBS symptoms including: bloating, abdominal pain, and loose or watery stools.

Both of these studies strongly suggest that bacterial overgrowth, which creates a low-grade infection, is a major part of IBS, and can be treated with antibiotics. In addition, I think the standard of care today strongly suggests using probiotics while on antibiotics. This has been shown to lower the incidence of antibiotic associated diarrhea (AAD), and especially Clostridium difficle diarrhea, which can lead to total removal of the colon or even death.

Probiotics alone have been shown to significantly help with IBS. More specifically, probiotics enhance gut barrier function, inhibit pathogen binding and modulate gut inflammatory response. They reduce visceral hypersensitivity associated with both inflammation and psychological stress. More importantly, probiotics can alter colonic fermentation and stabilize the colonic microbiota, show that dietary exposure to pathogens maybe less likely to create another relapse of symptoms.5

Once again we can see that the use of high fiber, essential oils (omegas), probiotics and digestive enzymes (Brenda Watson’s HOPE Formula) can be beneficial in preventing or treating intestinal inflammation—be it IBS or IBD.

Most surgeons on call on Thanksgiving or Christmas Day are not surprised when they get called into the ER to see a patient with right upper abdominal pain and tenderness radiating through to the back. There are also no surprises when an abdominal ultrasound shows a dilated gallbladder, possibly with a thickened wall, and gallstones ranging from the size of a pebble to the size of a marble or even an egg. At this point, the appropriate next step would be laparoscopic cholecystectomy, or removal of the gallbladder. This is one of the most common surgical procedures in the Western world today.

So how does a person find themselves in the operating room on Thanksgiving night? First of all, it didn’t just happen all at once. Gallstone formation takes months or even years. It is believed that low-fiber, high-cholesterol diets high in processed starchy foods contribute to the formation of cholesterol stones. Over-consumption of fatty and fried foods and refined sugar, as well as inadequate intake of vitamins B, C and E, are also factors thought to contribute to gallstone formation. Inadequate water intake and lack of exercise also play a role.

With the above diet, a bacterial imbalance in the gut will develop. The effect in the gut of this imbalance will be increased intestinal permeability (also known as leaky gut). As a result of leaky gut, more toxins are delivered to and processed by the liver. These toxins are sent from the liver to the gallbladder, where they are stored and concentrated along with the bile, which can lead to gallstones.

So how do the holidays fit into this? Very simply – a large meal high in fat and sugar will release the hormone cholecystokinin (CCK) from the duodenum (upper small intestine). CCK triggers the gallbladder to begin contracting and may move the stones into the cystic duct (which drains into the common duct and then into the duodenum) causing gallbladder obstruction, swelling, more inflammation, and severe right upper quadrant pain.

Many people do not realize they have gallstones. They may go years without symptoms and only discover the gallstones in an emergency room visit such as I described above. Other people do experience periodic attacks and are able to recover from them and choose not to have surgery. In either case, it’s prudent to take extra care at major holiday meals. A combination of gravy, ham, buttery mashed potatoes, candied yams and alcohol, followed by pumpkin pie and ice cream is the perfect recipe for a gallbladder stress test. The following recommendations could help you avoid that ER visit this holiday season:

• Eat smaller portions of any high fat, high-sugar foods
• Chew thoroughly
• Eat slowly, taking the time to enjoy the meal and company
• Take digestive enzymes with the meal
• Limit alcohol consumption

Most importantly, as a preventative measure, follow a high-fiber, plant-based, antioxidant-rich diet low in processed foods and saturated fats, fried foods and sugar. In addition to getting regular excise and having regular bowel elimination to reduce toxins, it is important to have a healthy balance of intestinal bacteria. This can be achieved by eating fermented foods (which are naturally high in beneficial bacteria) and taking high-quality probiotic supplements every day.
