Sugar As A Cause Of Cancer

It has been known for a long time that cancer cells can survive without the ordinary aerobic pathways of energy production. They can get energy from a metabolic pathway, which bypasses normal cell metabolism (aerobic glycolysis). But many attempts of designing a cancer therapy to exploit this difference have so far been unsuccessful.

This Mayo Clinic website even explains that it would be a myth that cancer would grow better with sugar. The following pieces of research question this myth.

Sugar makes cancer grow faster (activates oncogenes) in fruit flies

In this study from the Icahn School of Medicine at Mount Sinai in New York City fruit flies were used as an animal model. You may ask, why fruit flies; we are not fruit flies, we are humans! As incredible as it sounds, on a cellular level our cell metabolism and the cell metabolism of fruit flies is identical. But the generation time of fruit flies is much shorter and results can be seen in days and weeks. To achieve the same in human trials would take months and years. Also, researchers could breed a strain of fruit flies that was susceptible to develop tumors. When they were fed sugar, the fruit flies developed insulin resistance within a short time. This model was chosen by the researchers as it is known for some time that in humans insulin resistance from diabetes, obesity, and other metabolic diseases leads to a higher risk of developing breast cancer, liver cancer, colon cancer and pancreatic cancer. The researchers wanted to sort out what the metabolic advantage of the cancer cells was under these conditions.

The researchers found that the sugar in the diet activated silent cancer causing genes (called “oncogenes)” in the fruit flies that in turn helped to promote insulin resistance and the development of tumors. Because of the insulin resistance sugar could not enter into the normal body cells, but the tumor was using up all of the sugar allowing the tumor cells to multiply at a rapid rate. The end result was that the sugar from the diet fed the cancer cells directly making them grow faster. Interestingly, when these flies that had developed tumors on a high sugar diet were switched to a high protein/low sugar diet, the tumors stopped growing and were contained.

In this fruit fly example the researchers were subsequently able to block cancer cell growth by special cancer suppressing drugs (acarbose, pyrvinium and an experimental drug AD81), which were given in combination. 90% of the flies given the triple-drug treatment survived to adulthood while control flies not treated with this regimen all died of their tumors.

Although this model was only done in fruit flies and one could question whether or not this was relevant to what is happening in human cancer patients, the following piece of research puts this fear to rest.

Sugar As A Cause Of Cancer

Sugar As A Cause Of Cancer

Human breast cancer cell study in vitro

In January 2014 the American Society for Clinical Investigation published a collaborative study between the Lawrence Berkeley National Laboratory, Berkeley, California, CA and the Hokkaido University Graduate School of Medicine, Japan, which used human breast cells in tissue culture showing that sugar could cause breast cancer.

The original papers of this US/Japanese research team are quite technical and I do not expect you to understand this link where it is published. I posted it for those who want in depth information. The researchers used a simple tissue culture model where they could observe tumor growth in cell cultures under the microscope using a gel where the breast tissue samples were placed side by side with normal breast cells that served as controls. The cell cultures of both normal cells and malignant cells were obtained from the same reduction mammoplasty tissue samples. This way the cell cultures mimicked a situation as close to the reality of what is going on in a woman’s body when breast cancer develops.

The normal breast epithelial cells were seen in culture to get organized as a roundish cell formation (an acinus formation) while the cancer cells were growing as irregular cell clumps. This visual effect was reproducible and is depicted in the paper. With high sugar concentrations in the growth medium breast cancer cells multiplied at a faster rate, not so the normal cells. But some normal cells underwent a transformation into abnormal and cancerous cell types. On the other hand, when sugar concentrations were severely restricted, morphological changes took place where cancer cells slowed down their growth or stagnated while some of them even changed into the normal cell formation (acinus formation). Using various known oncogene stabilizers the investigators could show that the same effect was noted as with the low sugar concentration in the growth medium.

The investigators tested whether other cell lines of breast cancer would show similar results as to the effects of sugar feeding or restriction. They were able to show that high sugar feeding activated cancer cells, no matter where the cancer cell lines originated. The authors discussed that metformin, which is known to control the metabolism in diabetic patients and lowers blood sugar levels, has also been shown to calm down growth of cancer (due to stopping oncogene stimulation), which improves the survival rates of many different cancer types in diabetic patients; it also reduces the risk of developing cancer in those who are taking metformin.

Other investigators have shown in mouse experiments that an impressive lowering of cancer rates could be achieved with low carb diets.

Human evidence for cancer causation and cancer prevention

Several clinical studies seem to indicate that there is a higher cancer rate in diabetics where insulin resistance can lead to activation of cancer producing genes (called oncogenes) and cause various cancers. In this link colorectal cancer and pancreatic cancer are discussed in relationship to diabetes and insulin resistance. High glycemic foods (sugar, starchy foods) were associated with breast cancer, colorectal cancer and endometrial cancer. The majority of trials showed this association although not all. The more obese patients were, the more pronounced the insulin resistance was and the more the relationship to these cancers became apparent. A diet that is high in starchy foods like potatoes, rice and bread is causing pancreatic cancer as was shown by researchers at the Dana-Faber Cancer Institute, Brigham and Women’s Hospital and Harvard School of Public Health. High glycemic diets have shown to cause colorectal cancer, diabetes and being overweight. The Standard North American Diet (SAD) is a pathway to many chronic illnesses due its high load in refined carbohydrates. Ironically the abbreviation for it is “SAD”, which in my opinion reflects adequately its sad influence on health and well being. We know now that sugar and starchy foods lead to insulin overproduction, which in turn causes the metabolic syndrome (also known as “insulin resistance”). This causes the immune system to weaken and fat to be deposited as visceral fat in the stomach area. Visceral fat is metabolically very active as it secretes cytokines like tumor necrosis factor alpha (TNF alpha), COX-2 enzymes and others. Insulin and growth factors from the visceral fat gang up together with the elevated blood sugar, which activates tumor-producing genes (oncogenes) to cause cancer.

While cancer rates are higher in patients with insulin resistance, they were lower in patients who did have normal insulin levels. It is important to concentrate your efforts on normalizing weight, which will normalize insulin sensibility and avoid the development of cancer. Sugar avoidance and avoidance of cereals and starchy foods will help you achieve this goal.

Conclusion

Although the idea that sugar could cause cancer has been around since 1924 (Dr. Warburg), it has taken up to now to be proven in animals and humans.

The purpose of this blog was to show how there is a connection between the consumption of sugar and starchy foods and various cancers in man. Animal experiments are useful in suggesting these connections, but many clinical trials including the Women’s Health Initiative have shown that these findings are also true in humans. It is insulin resistance due to sugar and starch overconsumption that is causing cancer.

We are now in a position to know why people who consume a low carb diet, develop less cancer than people who consume a high carb diet. I have followed such a low carb diet (also known as low-glycemic index food diet) since 2001 and find it easy to follow. However, I do not dispute that it takes some discipline to change the old way of eating to the new one. The benefits are definitely worth it: you are feeling well now and you are staying well as you age.

Early Alcohol Use Will Result In Memory Loss Later In Life

Researchers found that heavy alcohol use in males during midlife paves the way to memory loss from dementia later in life.

I thought that this would be a good topic to review the effect of alcohol in general. Alcohol is a known cell poison, yet cardiologists keep on referring to the beneficial effects of that 1 glass of wine per day that will prolong your life. I will attempt to explain these diverse effects, where small amounts are supposed to be good for you while high amounts can be very damaging.

Review of the effects of alcohol

50% of the world population drinks alcohol, 10% to 20% have chronic alcoholism (Ref.1).  Just recently a Guardian news study was released showing that an astounding 25% of Russian men die before reaching the age of 55, compared to only 7% of men in the United kingdom and less than 1% of men in the US. The study looked at the effects of consuming large amounts of vodka.  There are about 10 million chronic alcoholics in the US. Chronic alcohol consumption leads to 100,000 deaths every year in the US. More than 50% of these deaths are from traffic accidents, the rest from medical problems caused by alcohol (Ref.1). Most of the alcohol gets detoxified through the liver cells and is metabolized into acetaldehyde. This involves the cytochrome P-450 system. That means that when a person also takes narcotics, sedatives or psychoactive drugs that are also metabolized through this liver enzyme system drugs and alcohol are taking much longer to be metabolized. This can lead to lethal overdoses that we hear about on TV all the time, hence the warning that you must not mix alcohol with drugs.

Early Alcohol Use Will Result In Memory Loss Later In Life

Early Alcohol Use Will Result In Memory Loss Later In Life

Alcohol is a cell and nerve poison. The most vulnerable organs in the body are the liver, brain, heart, pancreas, bone marrow and stomach. So, here are a number of conditions caused by drinking alcohol:

a)    Anemia: When a person drinks heavily and regularly anemia shows up in a blood test. Alcohol has a toxic effect on the bone marrow, which interferes with the production of red blood cells. But certain vitamins required by the bone marrow to manufacture red blood cells are often also missing in the diet of an alcoholic, which contributes to anemia as well.

b)    Cirrhosis of the liver develops in 10% to 20% of heavy drinkers. With cirrhosis part of the liver cells get replaced by fibrotic tissue and in advanced cases this can lead to a hepatic coma and death. Others are developing alcoholic hepatitis. This is an inflammation of the liver with fever and jaundice where the skin and eyeballs turn yellow. It is associated with severe abdominal pain.

c)    Gastritis: Alcoholic gastritis is common, but often undetected. The affected individual may just have stomach pains for a few days, or vomit food and/or blood in addition. With continued use of alcohol it may turn chronic. Alcoholic gastritis can turn into gastric ulcers with massive bleeding that often lead to death.

d)    Pancreatitis: The pancreas is a particularly vulnerable glandular tissue, which gets damaged by regular alcohol intake and with chronic alcohol intake gets partially replaced by fibrotic tissue causing the feared and painful chronic pancreatitis. This is a condition with vomiting and severe abdominal pains that can be unrelenting.

e)    High blood pressure, seizures, dementia, depression, heart irregularities and nerve damage:

You may ask yourself how all of these conditions would be reasonably under one heading. The heading for this is “nerve damage”. Let me explain: The sympathetic nerve is very sensitive to alcohol toxicity and when the sympathetic nerve fibers are damaged, you will develop high blood pressure. You see your physician, get blood pressure medication, but the pressure is difficult to control, if you continue to drink alcoholic beverages. It does not make sense to just add blood pressure pills and hope that this will cure your problem. Seizures are due to direct nerve damage in the more sensitive parts of the brain, which will cause these areas to produce extra electrical activities, which we call seizures. Again, just treating with anti-seizure medications is not the solution. Avoidance of alcohol is the other part of the treatment schedule. Dementia from heavy alcohol use is due to direct nerve atrophy in the brain. Our brain shrinks normally 1.9% to 2.8% per decade, depending on which research papers you read. But in the presence of heavy drinking the frontal lobe of the brain is particularly vulnerable to brain shrinkage.

As this publication shows, mild and moderate drinkers did not suffer more frontal lobe shrinkage than abstainers, but heavy drinkers had a 1.8-fold higher risk of frontal lobe shrinkage on average when compared to abstainers. It was calculated that alcohol had contributed 11.3% to that frontal lobe shrinkage.

The rest of the toxic effect on the nerve tissue explains why depression would develop. The frontal brain contains most of the serotonin producing nerve cells. When serotonin-producing nerve fibers get damaged, the body does not produce enough serotonin to prevent depression from setting in; GABA producing cells often also get damaged, which causes anxiety. It’s not good enough to just prescribe anxiolytic drugs to which the patient will get addicted. The whole person needs to be treated, and abstinence from alcohol has to be part of the program.

Heart irregularities (atrial fibrillation, ventricular fibrillation) can be life-threatening complications due to the toxic effect of alcohol on the nerve fibers within the heart muscle. Emergency physicians are aware of the connection of these conditions to alcohol consumption. Some people’s hearts are more sensitive to the effects of alcohol than others. The most common cause of temporary atrial fibrillation is excessive alcohol intake (holiday heart) according to Ref. 2.

Finally there is the effect of alcohol on nerves in the body. This explains that heavy alcohol consumers can come down with painful pins-and-needles sensations in their hands and feet or with numbness or loss of muscle strength. When the parasympathetic nervous system is affected embarrassing incontinence or constipation can result. Erectile dysfunction in men is also very common. Viagra and continuing to drink is not the solution.

f)      Gout: This painful formation of uric acid crystals in joints can be precipitated in sensitive individuals by consuming alcohol in combination with eating large helpings of beef. There may be a history of gout in the family. Treatment for this is to refrain from alcohol and avoid foods that are leading to uric acid production when ingested.

g)    Cancer: When the body detoxifies alcohol in the liver, the breakdown product is acetaldehyde, which is a known cancer producing substance. A whole array of cancers are known, which come from heavy, chronic alcohol consumption: cancers in the mouth, larynx, esophagus, stomach, pancreas, liver and colorectal cancer have all been linked to excessive alcohol intake.

h)    Cardiovascular disease: heart attacks and strokes can be caused particularly by binging; it is thought that binging makes platelets from the blood more sticky so they clump together and cause blood clots, which in turn leads to heart attacks and strokes.

i)      Infections: Alcohol weakens the immune system, which is another effect on the bone marrow similar to causing anemia, except that this is the toxic effect on the white blood cells and lymphocytes. Heavy alcohol consumers are more prone to pneumonia, to HIV, sexually transmitted diseases, and tuberculosis.

Cardiology view of preventative alcohol

Despite all of these hair raising toxic effects cardiologists have painted the rosy picture that 1 glass of wine for women and 2 glasses of wine for men per day will prevent heart disease. What is the true story here?

Ref.2 points out that there are about 100 prospective studies that confirm that there is an inverse relationship between mild to moderate alcohol consumption and “heart attack, ischemic stroke, peripheral vascular disease, sudden cardiac death, and death from all cardiovascular causes”. It describes further that the reduction of risk in these various studies was persistent and consisted of a 20% to 45% risk reduction. Using blood tests investigators have found that this is because of an increase of HDL cholesterol, reducing blood clotting, making platelets less sticky and reducing inflammation as evidenced by a reduction of the C-reactive protein. Further research has pinpointed that it is the phenols and resveratrol that are contained in alcoholic beverages that are responsible for the beneficial effects. The bad news is that three glasses of wine or more do the opposite, so does binge drinking. Unless you are extremely disciplined and never increase your allowed limit (1 drink for women, 2 drinks for men) you will CAUSE heart disease rather than PREVENT it (Ref.2). Some people have a family history of breast cancer or colon cancer and they should avoid alcohol altogether; also people coming from alcoholic families should avoid alcohol.

Conclusion

Where does this leave us with regard to prevention of heart attacks, strokes and hardening of the arteries in the legs (peripheral vascular disease)? If you are disciplined and stick to the limits, you could prevent 20% to 45% of cardiovascular risk. The brain study mentioned in the beginning of the blog would also confirm that there was no difference between dementia or brain shrinkage when mild to moderate drinkers were compared to abstainers over 10 years. What is not told by the wine industry is that the same effects that prevent cardiovascular disease in mild to moderate drinkers can also be achieved by natural means: exercising regularly will raise your protective HDL cholesterol; taking ginkgo biloba, flax seed and omega-3 fatty acids thins your blood and the platelets are getting less sticky; omega-3 reduces inflammation and resveratrol elongates telomeres making you live longer. At the A4M conference in Las Vegas in December 2011 there were three speakers who pointed out that even small amounts of alcohol will poison mitochondria of your cells and interfere with normal hormone action. This was enough to make me join those who abstain alcohol completely. One thing has not yet been investigated in long-term studies, namely how small effects of alcohol may affect the body over several decades and over an entire lifetime. Despite all the promises of interest groups that red wine is a trendy drink for those interested in heart health, the fundamental long-term studies are missing. What does a guy do with a healthy heart and a brain that is not functioning too well? I just do not want to be the guinea pig in that worldwide study.

Pollution And Soaring Lung Cancer Rates

In early 1900 lung cancer was unheard of. This was before the cigarette industry started to mass-produce and market cigarettes.

However, ever since the arrival of the industrial revolution air quality has suffered. In China poor air quality has now reached such enormous values that the specialized cancer agency of the World Health Organization, the International Agency for Research on Cancer (IARC) has labeled poor air quality as one of the causes of lung cancer.

When you rank countries by average air pollution measurements, one sees that Europe, the US and South America overall have good ratings, whereas the Middle Eastern countries, China and India have poorer ratings.

However, when the pollution index of cities where the population is much denser than in the countries at large, are tabulated a much different picture emerges: Cities in Iran, India and Pakistan stand out as particularly bad followed by cities in China, Eastern Europe, Paris, London, Berlin, cities in California (the populous State), Chicago and New York.

Pollution does not stay local, but travels through the stratosphere around the globe. The result is that now 10 to 15% of lung cancer in the US occurs in patients who never smoked. This translates into 16,000 to 24,000 deaths annually of never-smokers in the US.

In certain cities such as Beijing the lung cancer rates have doubled in 9 years between 2002 and 2011. As this article shows lung cancer in never smokers can be caused from exposure to radon, to second-hand tobacco smoke, and other indoor air pollutants can also cause such cancers. But the outdoor air quality has been a problem ever since the industrial revolution, which started around Europe in the 1800’s and first part of the1900’s. In the latter half of the 1900’s much of the industrial wave has migrated to the Middle East, to India and China. But the air quality of the whole world has suffered as the jet stream and other air currents carry pollution in the stratosphere all around the globe.

Pollution And Soaring Lung Cancer Rates

Pollution And Soaring Lung Cancer Rates

History of pollution in various regions

1. In Germany’s  Ruhr district (“Ruhrgebiet”) in North Rhine-Westphalia, a highly populated industrial area, pollution reached a peak in the late 1950’s. From 1963 onward many of the coal mines, iron ore mines and other mineral mines closed down. 50 years ago the German Chancellor, Willy Brand was concerned about the environment and promised that blue skies would return to the Ruhr district again.  A special task force was initiated and maximally allowable limits were established for industries’ pollution emissions and enforced by the German government. Government and industry were co-operating in developing anti-pollution measures, which have cleared up a lot of the pollution since. With regard to car emissions lead free gasoline was introduced and carburetors ensured more complete burning of exhaust gases. This is now common and accepted anywhere except for diesel fume exhaust, which nobody wants to address despite proven carcinogenicity.

Now Germany is one of the leaders in green technology, which is also important for tourism.

2. England has its own legacy of pollution in soil and air from the industrial revolution. The soil of moorland, which soaked up acid rain for decades, is more acidy than lemon juice and it will take a long time despite industrial complexes having closed long time ago, before the soil quality will be returned to normal.

3. Hamilton in Ontario/Canada has had a longstanding pollution problem, which I witnessed from 1976 until my departure in 1978. It is well known that Stelco, the local steel plant downtown Hamilton is sending polluting emissions into the air. In 1976 a vising professor from Australia gave an interesting talk about a study that was done at that time regarding the risk of developing bronchogenic carcinoma (a synonym for lung cancer) in the immediate surroundings of the Stelco plant. He said that this was one of the first studies to show that the distance of people’s houses from the source of pollution mattered as that determined how concentrated the air pollution was (the closer the more polluted the air). This  affected cancer rates: they were much higher in the immediate surrounding of Stelco when compared to the average rate in the rest of Hamilton. This difference was very significant within a radius of 1 kilometer (= 0.62 miles) from the Stelco plant.

Just in May of 2013 the local cancer agency of Hamilton announced that the lung cancer rate in Hamilton was higher than elsewhere in Ontario because of a combination of poor air quality and of a higher percentage of people smoking. Then in August 2013 the city of Hamilton announced a new air pollution bylaw for stricter pollution measures to improve the air quality in the downtown area. It is just a pity that Hamiltonians had to wait until 2013 before the city approved an anti-pollution bylaw that could have been passed 50 years earlier like in Germany’s Ruhr district!

4. In 2008 Pittsburg, a former steel manufacturer town like Hamilton, Ont. outdid Los Angeles with regard to small particle air pollution.

Lung cancer prevention by the authorities

As mentioned before up o15% of lung cancer is caused by environmental exposure. So, we ourselves can only prevent 85% of lung cancer by not smoking and not exposing ourselves to industrial emissions or to smoke from incense. However, in many cities around the world you will get exposed to air pollutants that are well above the safe limits, so the risk of getting lung cancer from just breathing the air there can be much higher than in rural areas where there is no industry.

Technologies to control air pollution are widely available. We need to exert pressure on politicians to show leadership around the world. Government regulations to lower emission rates need to be put into place and inspectors need to ensure the rules and regulations are adhered to. Without reducing emissions of cancer producing gases and chemicals right at the source (open burning of cuttings in orchards or burning cut trees), cutting emissions of cars, planes, ships, diesel cars, locomotives, electric generator plants etc. the air quality will not improve. Despite some costs involved industry, governments and individuals have to work together to make clean air happen.

The residents of those countries that have low pollution values will not benefit, if pollution continues to occur in other parts of the world as it just travels in the stratosphere around the globe until it arrives right here at home! We need an international pollution police. Satellites can be used to monitor where pollution occurs and this can be followed up through the local regulatory bodies with penalties and remedial actions.

What can I do personally to prevent lung cancer?

1.The most obvious step is to quit smoking and ask smokers who come to your place to smoke outside (not in your home).

2.Consider moving away from the city, if the air quality is unacceptable to a place where there is low air pollution.

3.Vitamin D3 has been shown to prevent colorectal cancer, but as there are vitamin D receptors found on the surface of various cells in tissue around the body including the lungs, many researchers feel that this vitamin in higher doses (2000 IU to 5000 IU) has probably a wider applicability in preventing cancers, even lung cancer.

4.Cutting out sugar and adopting a Mediterranean type diet is a prudent thing to do; also cutting down your calories to the maintenance you need (mildly ketogenic diet). If you bought body composition scales, it would display what your daily calorie consumption is and you should not exceed this, or else you’ll gain weight. An aging man who is overweight will experience hormone changes as fat is being metabolized and the enzyme aromatase contained in fatty tissue will turn male hormones (testosterone, DHT, androstenedione) into estrogen. Estrogen (particularly estradiol) is a known carcinogen that has been proven to cause breast cancer in women and prostate cancer in men. However lung cancer is also being promoted in women by estrogen as discussed in this link. In men one needs to remember that lung cells have estrogen receptors and there is concern in aging men with higher estradiol levels that this can promote cell divisions in existing lung cancer. So, it is important to maintain a normal body mass index between 21 and 24 (well below 25.0 and well above 18.5, which are the official accepted limits). This way there is no problem with insulin resistance (too high an insulin level), and other metabolic substances (cytokines, growth hormone like factors and tumor necrosis factor-alpha from body fat) that are cancer promoting.

5. If testosterone deficiency is present, which is common in older men, testosterone will have to be replaced with bioidentical hormones. It is a myth that testosterone would cause prostate cancer. Testosterone in males is necessary to maintain a normal metabolism including the immune system, which then can fight lung cancer and any other cancers.

6. Exercise and reducing beef consumption are also often mentioned in terms of preventing lung cancer.

7. Here are several recommendations from the LifeExtension Foundation that I found very useful in terms of lung cancer prevention. This link shows that antioxidant vitamins such as vitamin C, alpha tocopherol, the minerals selenium and zinc are also helping to reduce the lung cancer rate. Drinking green tea has also been shown to be effective in a dose-response curve manner (more tea protecting more from lung cancer). Vitamin B12 and folate have been shown to reduce abnormal bronchial cell growth in smokers as shown by repeat bronchoscopy studies.

8. Those who have been smokers in the past and those who have been around heavy smokers for more than 10 years in the past should consider having a preventative bronchoscopy done by a lung specialist (also called respirologist or pulmonologists). This way any suspicious areas with precancerous lesions can be biopsied during the procedure and attended to.

Hopeful research for new lung cancer treatments

Lung cancer is a disease that is best prevented. Once a person gets lung cancer, the prognosis is still very poor. However, cancer researchers are getting close to newer treatments involving genetically modified T-cells (killer cells) as was recently achieved for leukemia. Similar research is going on regarding ovarian cancer, melanoma, lung cancer and pancreatic cancer.

Conclusion

It is not acceptable to let pollution take its course , the way politicians around the globe have handled this in the past 6 decades with a few notable exceptions mentioned. We all suffer a higher risk of getting lung cancer, even if we have been life-long non-smokers. Right now up to 15% of lung cancer in most populations are of this type. However, in Beijing this number is already much higher. The technology is available; Germany has led the way in the Ruhr district in the 1960’s and beyond. In my opinion the G8 meetings should have this high on their agendas and send technological aid to all the regions that have higher than the average world pollution index under the mandate of a special UN commission. This should be supported by the major industrial players with the knowledge that they will prevent the death of millions of potential consumers down the road, which will on the long-term pay off the relatively minor investment of installing pollution controls, before lung cancer levels rise even more.

Music More Powerful Than Anti-Anxiety Drugs

When was the last time you saw your physicians for anxiety and you were given a prescription that said: “for anxiety listen to your favorite music!” instead of receiving a prescription for an anti-anxiety drug (anxiolytic). This is exactly what a recent study suggests that showed prior to surgery you can control your anxiety either with anti-anxiety drugs or by listening to your favorite music. Listening to your favorite music will do you no harm, while many drugs do have harmful side effects.

How singing can change the brain chemistry

Other studies have investigated how singing can change your brain functioning in terms of brain chemistry. The researchers found that singing will release dopamine in your brain, which is responsible for feeling pleasure; it will stimulate your immune system by elevating immunoglobulin A and decreasing cortisol (the stress hormone). This in turn will preserve your immune cells (lymphocytes). Oxytocin levels of your brain are increased, which promotes social affiliation. It also calms down the autonomic nervous system resulting in a better airway opening, calming of your heart rate and soothing the wave-like muscle contractions in your gut, medically called peristalsis. You would refer to that as “butterflies in your stomach”. Music therapy reduces pain and anxiety by 50% and is important for children and adults alike.

Pain and anxiety reduced

A study in Germany showed that pain and anxiety were significantly reduced with music therapy. A Taiwanese study of women in labor found that music therapy significantly reduced pain and anxiety of women during labor. Ref. 1 explains that music therapy is useful as an adjunct to treating cancer pain, and reducing anxiety associated with colposcopy procedures. It also can help when treating patients who had heart attacks in the setting of a cardiac care unit.

Music More Powerful Than Anti-Anxiety Drugs

Music More Powerful Than Anti-Anxiety Drugs

Hypnosis and guided imagery

Music has been successfully combined with clinical hypnosis and guided imagery where words are carefully chosen to help the patient experience pleasant feelings, which counteract the experience of pain, anxiety or fear of dying. A simple relaxation CD or tape with soothing background music will facilitate this type of therapy. This is useful for patients in a palliative care unit where they prepare themselves to accepting the inevitable death from an incurable disease. But chemotherapy patients undergoing these procedures for cancer treatments also have benefitted from a significant reduction in nausea, vomiting (side effects of chemotherapy) and pain.

Autism and music therapy

A Cochrane study showed that autistic children did better in terms of communication skills when music therapy was incorporated into the treatment protocol. One of the core deficits in autistic children is in the area of communication and social skills. This is where music therapy was most effective. Behavioral problems (stereotypic behavior) in autistic children did not respond to music therapy. A comprehensive treatment program for autistic children should therefore incorporate music therapy. Here is a blog that describes what difference music therapy can make in the lives of autistic children written by a member of the American Music Therapy Association.

Substance abuse and music therapy

An area where you may not expect music therapy to have a role is in the area of drug and substance abuse rehabilitation , which is discussed in more detail in this site. The beauty about music therapy is that it is not a drug, yet the natural endorphins that are released by the brain help the affected person getting through withdrawal easier. Music therapy helps building up self-esteem, participating in group activities, promoting self awareness and expressing feelings.

Mood disorders in adolescents

One important area where music therapy has been employed is with anxiety and depression in adolescents. Adolescents spend an average of 4 hours per day listening to music. So they are already programmed to listen to music. With the help of a music therapist they can be directed to listening to the type of music that will help them get motivated, relax more, make them feel accepted and be part of their peer groups. In this study the authors suggested to combine music therapy with dance and art therapy. In this way the whole person gets involved in the treatment and this can be integrated with conventional antidepressant treatments at reduced doses (with less side-effects) or with cognitive therapy.

General objectives of music therapy

Music therapy is best incorporated into a treatment protocol as an adjunct. It can help reduce the use of drugs for psychiatric patients, for people with anxiety and for patients with pain conditions. The Cleveland clinic has a useful summary about music therapy, which describes the uses of it for reducing anxiety, for helping with coping skills, mood improvement and distraction from pain. There are registered music therapists you can ask for help. The website of the American Music Therapy Association may have other useful links for you.

Conclusion

Music therapy is a treatment modality with no side effects, but providing effective treatment for quite an impressive range of clinical conditions as discussed. Music therapists are widely available in the US and many other countries. This treatment can be integrated with conventional or complementary treatments. It helps people to heal the body as a whole unit (mind and body).

Fighting Back Against The Flu

Every year there is concern about the upcoming flu season. Mostly the discussion centers on the composition of the latest flu bugs and what type of strains would be included in the latest vaccine recommended. The first flu case of the season has just been reported in a child. Here I am going to review what you can do to minimize your probability of getting the flu, or if you get it, how to minimize the severity of the illness.

The immune system

We know for some time that the antibody-mediated immune system is what helps overcome flus. The body’s immune system produces antibodies against the flu via T-helper cells that recognize the glycoprotein (hemagglutinin) of the flu virus and pass a signal on to B cells (bone marrow derived lymphocytes), which in turn are turned on to produce a lot of antibodies (Ref.1). These protect you from future flus of this type. If you have pre-existing antibodies that fit the bug in circulation you are OK ,and you will usually not get the disease.

The factors that protect you from the flu

However, there are many other factors that support your immune system. I will discuss the most important factors in more detail here.

1. We do know that vitamin D3 strengthens the immune system. I would recommend 1000 to 2000 IU per day in the wintertime, but up to 4000 IU or 5000 IU per day during an active epidemic would be reasonable. There is less flu when people are taking Vitamin D3 supplements.

Influenza A was reduced in school children supplemented with 1200IU of vitamin D3. This study recommended higher doses of 2000 to 7000 IU of vitamin D3 per day; but it also stated that as a precaution serum vitamin D levels should be monitored (technically it is serum 25-hydroxy-vitamin D levels that are measured) to avoid vitamin D toxicity. Normal levels are between 40-70 nanograms per ml. Toxic levels are above 100 nanograms per ml. Your family doctor can order a serum 25-hydroxy-vitamin D level for you.

2. Eating fruit and vegetables is important for maintaining a healthy immune system. In a randomized study from Belfast, UK elderly volunteers (82 of them, aged 65 to 85) were assigned to either eat 2 portions or 5 portions of fruit and vegetables per day over 16 weeks. At 12 weeks into the trial both groups received a Pneumovax II vaccination, and the antibody response was measured at the end of the 16th week of the study.  There was a significant increase in antibody binding capacity to pneumococcal capsular polysaccharide in the 5 portion fruit and vegetable group compared to the 2 portion group that had no such increase. The authors concluded that there is a measurable improvement of the immune system when an older population increases their fruit and vegetable intake.

3. Avoid stress, because stress has been shown to weaken the immune system. This review shows that the immune system is weakened by the stress response via the elevated corticosteroid hormones (the stress hormone ACTH stimulates cortisol release from the adrenal glands). The stress of social isolation is also contributing to the weakening of the immune system in older people.

4. Exercise moderately and your immune system will get strengthened. Over exercising should be avoided as too much cortisol is released from your adrenal glands, which is toxic to lymphocytes thus weakening your immune system.

5.  Socializing is good for you as studies have shown that you live 2 ½ years longer. This study here is from Connecticut, but other studies confirmed this as well.

6. Make love. The endorphins that are released in the process stimulate the immune system.

7. Take probiotics, because they help your gut flora to stay normal. A normal gut flora promotes a stronger immune system as the Peyer’s patches (clumps of immune cells) in the gut wall are intimately linked to the immune system. In this way probiotics indirectly support your immune system.

8. Avoid smoking.  Smokers have more upper and lower respiratory tract infections than non-smokers. Here is information that explains this as well.

9. Get enough sleep. The circadian rhythm of your hormones ensures that your hormones function at their optimal level. Melatonin from the pineal gland is important in triggering the circadian rhythm, but melatonin itself supports the immune system as well. Your adrenal glands need resetting overnight so that cortisol is secreted according to your stress level, not too much and not too little. Overstimulation from performance sports, grief reactions, car accidents, injuries etc. lead to a surplus of cortisol and weakening of the immune system.

10. Take your flu shot (but without thimerosal) every year, but take it as a single shot (without thimerosal as a preservative). This CDC link explains that single shot flu vaccines are available without thimerosal. I recommend this type of flu vaccine. The central nervous system is extremely sensitive to nanograms of mercury, and it is for this reason that I would not buy into the argument of the CDC that one should not be concerned about safety of thimerosal. The newest for this flu season is the quadrivalent (or four-strain) flu vaccine, which is now available in pharmacies throughout the US.

11. Vitamins and supplements support your immune system, particularly vitamin D3. DHEA, which is available over the counter in the US stimulates antibody production when the flu vaccine is given, particularly in the elderly, in other words DHEA strengthens the immune system Vitamin C is known to support the immune system and is rapidly depleted in those who suffer from any viral infection. There are other nutrients that are useful to stimulate your immune system.

12. Consider herbs: Echinacea, Siberian ginseng, Asian and American ginseng, astragalus, garlic, and shiitake, reishi (also called “lingzhi mushroom”) and maitake mushrooms have all been shown to stimulate the immune system with negligible side effects.

13. Wash your hands, particularly when there is a flu going around. Door knobs for instance are known to keep live viruses for 2 to 8 hours, so washing your hands will reduce the amount of virus you are exposed to.

Conclusion

There is no single solution to prevent the flu, but we can all minimize our exposure to the virus and strengthen our immune system. Although it is wise to get a yearly flu shot to boost your immune system (without thimerosal as a preservative) just before the epidemics come around, this alone is not as good as combining the non-specific factors mentioned here with it. Particularly vitamin D3 (2000 IU to 4000 IU per day) and the old stand-by vitamin C (1000 mg to 2000 mg daily) will stimulate your immune system. Spice up your dinners with mushrooms that stimulate your immune system (maitake, shiitake, reishi mushrooms). Go to bed early enough to allow your circadian hormone rhythms to be reset overnight as you sleep. This will stimulate your immune system (from melatonin and DHEA of your adrenal glands).

Flossing and Brushing Saves Your Heart

It was not until about the mid 1990’s when it became apparent that gum infections and severe tooth decay could cause inflammation in the blood measurable by using the CRP marker (C-reactive protein). As this link shows Dr. Joseph Muhlestein at the University of Utah demonstrated in 1996 that chronic gum infection could cause a heart attack. He isolated the bacterium Chlamydia pneumoniae in 79% of patients undergoing coronary bypass surgery, while samples from heart transplant patients isolated this bacterium in only about 5%. The new thinking was that bugs that multiply in diseased gums could migrate into the blood and cause platelets from the blood to clump together and block coronary arteries causing heart attacks. Harvard University researchers have confirmed this. In the past it was known that a bad tonsillitis with an aggressive bacterium, Streptococcus viridans, could cause subacute endocarditis, a dangerous infectious disease of the heart valves, which can be responsible for sudden death in younger persons. Neglected cavities in teeth can also harbor this bacterium. Another study in 2009 showed that two particular strains of bacteria in infected gums, Tannerella forsynthesis and Preventella intermedia, were associated with an increased risk for heart attacks; but it was more the overall burden of bacteria in the infected gums than the specific bacteria strains that mattered most.

Flossing and Brushing Saves Your Heart

Flossing and Brushing Saves Your Heart

 

Preventing heart disease by brushing and flossing

With this background it is easier to understand that we need to take good care of our teeth and gums, if we want to maintain good health. As a start most people should see their dental hygienist (who usually works in a dentist’s office) twice a year. The dental hygienist will probe the depth of gingival pockets with a periodontal probe. A normal depth measures up to and including 3 mm. Deeper pockets than that usually indicate that the patient did not floss regularly. One needs to floss at least once per day, better twice per day and it should not bleed after flossing (initially when a person flosses for the first time the gums tend to bleed a bit).

The hygienist will do scaling of plaques on the tooth enamel. Any cavity that is detected will be brought to the attention of the dentist. At the end of the scaling procedure fluoride is applied, which puts a coating on the tooth surfaces to prevent tooth decay.

When deeper pockets (6 mm or more) are detected a trial of subgingival root brushings has shown to have a very beneficial result within only 14 days.

Periodontal pockets were improved and bacterial counts of periodontal infections were shown to have improved as well.

Oral care and cavity prevention in the population

It has been accepted for quite some time that a combination of brushing and flossing are the best methods to control dental plaque, which is the precursor for cavities.

In order to test the knowledge of adults in families with small children these authors from the School of Public Health of the Maryland University investigated Maryland’s adult population knowledge regarding caries prevention. It turns out that there were deficiencies in knowledge about the prevention of dental caries and the importance of fluoride to create strong, decay resistant enamel.

A randomized, prospective study is planned in Hong Kong which will start teaching oral hygiene to kindergarten children aged 3 and will be reinforced several times later to instill good dental hygiene behaviors into these children’s health routine as outlined in this link. Not only is it important to teach brushing and flossing, but also food habits with cutting down on sugary and starchy snacks as these foods make the saliva acidy promoting caries producing bacteria in the plaque.

This English study shows that a primary school based caries prevention program reduced caries by 35% when sugar intake was limited in the interventional group and brushing of teeth was done twice per day along with flossing.

An addition to flossing for those with narrow tooth intervals or those with braces is a waterpik system. This can be used to clean food residues from the spaces between your teeth and from gum pockets. Flossing once or twice per day is still needed to remove plaque to avoid tartar build-up. Before bedtime it is advisable to floss first, then use a waterpik, then use your electric toothbrush with a fluoridated toothpaste. During the day use the waterpik after meals followed by brushing with an electric toothbrush with non-fluoridated toothpaste.  Water Picks are also called “water flossers”; they are easier on your gums.

Other measures helpful in preventing tooth decay

Xylitol is a natural sweetener originally derived from birch. Sugarless gum often is sweetened with Xylitol. This study has shown that chewing Xylitol containing gum can effectively reduce caries. This paper describes that the increased saliva production from chewing gum provides a slightly alkaline environment for teeth. This helps to clear out sugar faster from the oral cavity after a meal, inhibits bacterial growth, neutralizes the pH in plaque that is on the acidy side after sugar consumption. The authors concluded that chewing Xylitol gum is a useful addition to the other known preventative measures of dental decay prevention, such as brushing and flossing teeth.

The techniques the dentist is using to treat plaque and dental decay have been refined by a new technique describe in this Australian publication as a minimum intervention caries prevention program.

The four methods used in minimum intervention dentistry are described here.

1. Recognition: to recognize potential caries factors early through lifestyle factor analysis and saliva testing.

2. Reduction: alter the diet and lifestyles to increase the pH of the saliva, which will reduce the risk factors for caries.

3. Regeneration: to arrest and reverse minimum lesions at the earliest stage. Use agents such as fluorides and casein phosphopeptides-amorphous calcium phosphates to achieve this.

4. Repair: when a cavity is present, a technique of “conservative caries removal” involves using bioactive materials to allow healing of the dentine layer of the tooth.

Reduction of cariogenic bacteria

I already mentioned above that alkalization of saliva by chewing Xylitol gum could significantly help prevent tooth decay. It does so by raising the pH, while chewing on sugary foods or starchy foods lowers the pH (making it more acidy). Growth of caries producing bacteria, which are called “cariogenic bacteria” is stimulated by acidy saliva and inhibited by alkaline saliva. For this reason people whose diet consists of a lot of vegetables and greens will have more alkaline saliva and are less prone to develop cavities. The worst foods to get cavities are sugar in its many disguises and starchy products (candies, bread, rice, potatoes, pasta, bagels, cookies, cakes).

What can cause bacteria from the mouth to appear in the blood? One common condition is periodontitis, which is a chronic inflammatory condition of pockets of the gums around the teeth. This originates from neglecting your teeth and not flossing. Smokers are more afflicted by this as well. Dental procedures called scaling and root planing are often done for chronic periodontitis. This study from January 2013 shows that there is about the same amount of bacteria that leak into the blood following these procedures when compared to flossing.

Sometimes a dentist will recommend using a short-term antibiotic to reduce the leakage of bacteria into the blood, particularly with people who have heart valve problems or had porcine heart valve replacement in the past. This publication from 2009 also describes that dental flossing causes bacteria to be shed into the blood (bacteremia).

Conclusion

Dental self-care should be taught to children at an early age to educate them to brush their teeth twice a day and floss them at least once per day. At the same time they need education what causes cavities in terms of food intake and that fluoride can help make teeth more cavity resistant. They should avoid sugar in pop, candies and cookies etc. Parents best teach by example! Regular visits to the dentist’s office will safe money on the long term. Regular scaling by a dental hygienist every 6-month will remove plaque from which cavities develop when bacteria thrive in them and produce acids that affects the enamel. Minimum intervention dentistry discussed above (4 methods used) can prevent your teeth from decaying. Regular flossing will keep your gums healthy and reduce the colonization of the mouth with bad, cariogenic bacteria. With all this in place you likely will keep your teeth for a long time and not need dentures or tooth implants because of lost teeth. At the same time you will prevent your immune system being overwhelmed by mouth bacteria, which could have lead to a heart attack had you neglected your teeth. As mentioned in the beginning, a CRP blood test is a useful tool to rule out chronic infection.

What We Can Do About Superbugs

Introduction

This article is about what we can do about superbugs. Several decades ago nobody talked about superbugs. Then came stories of “flesh-eating disease” or necrotizing fasciitis. Since 2001 it became obvious that these cases have become more common. Methicillin-resistant Staphylococcus aureus (MRSA) was often the underlying cause.

Antibiotics for weight gain in cattle

Government bodies accuse physicians of overprescribing unnecessary antibiotics for viral colds and flus. All physicians had to attend educational programs as part of the continuing education programs to use antibiotics only sparingly.  But the frequency of these serious infections often requiring amputations and mutilating surgeries continued to escalate. Research into the phenomenon of increasing superbugs took place already in the 1970’s. In 1977 the FDA came to the conclusion that antibiotics were used widely in the US by the agroindustry for weight gain in livestock (pigs, cattle, chicken, turkeys). Although masked as protecting animals from infections, the real motivation of the farmer was to increase profits. The FDA recommendation in 1977 to change the practice of feeding livestock antibiotics did nothing to change that.

Farmers continued to use the old antibiotic feeding practice

After a court review in 2012 a New York court ordered the FDA to do something about the same problem. The answer was a lame recommendation of a voluntary program to downsize the use of antibiotics in livestock, requiring a vet and a prescription for antibiotics. The problem with this is that farms had no mandatory checks of livestock by trained inspectors. The ruling about antibiotic reduction contained no penalties for farmers who continued the old antibiotic feeding practice. Fast-forward to an American citizen who visited India recently as told in this story.

Superbugs are all over the world

It is clear that superbugs are all over the world. It is also clear from this article (and other literature I have reviewed) that 80% of today’s antibiotics are fed to livestock, not to treat infections, but because of their effect on weight gain in livestock and the associated larger profits. The result is that we are looking at farming practices that produce deadly superbugs. Next we are reading headlines about a recall of meat meat and meat products.

Here is an interesting list from the Environmental Working Group, which shows what percentage of meats in your neighborhood grocery store is contaminated, and these are the numbers for superbug contaminations: The worst is ground turkey with 81%, pork chops with 69%, ground beef with 55% and chicken breasts, wings or thighs with 39%.

What We Can Do About Superbugs

What We Can Do About Superbugs

Wash meat thoroughly

This shows how important it is to wash meat thoroughly and to cook it long enough to kill the superbugs. It is also extremely important to frequently wash your hands when you prepare meat. This avoids  colonizing your skin surface with superbugs. The first step is for a person to have skin surface flora with superbugs. The second step is to get a small abrasion or a skin sore where a superbug can enter. The final step is that this bug multiplies under the surface of the skin and starts a serious infection. If the immune system is not in top shape to eradicate these bugs right away, the next step may be flesh-eating disease or toxic shock syndrome.

Solutions to stay on top of Superbugs

In northern Saskatchewan, one the provinces of Canada, an 8 year community based study was done to see whether it would be possible to reduce community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) by a combination of hand washing and education regarding appropriate antibiotic use. Using this program it was shown that in the time period of 2006 to 2008 the infection rates went down from 242.8 to 129.3 infections/10,000 population, which is almost half of the infection rate from before.

Hospital associated methicillin-resistant Staphylococcus aureus

What can physicians and nurses do about hospital-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) and other superbugs in the hospital? In a hospital it is extremely important that HA-MRSA free patients do not get exposure to this superbug . Their immune system is already weak from the underlying disease. This is how they got into the hospital. At Stanford University a robot was developed that emits pulsating ultra violet light to kill any leftover superbug after the initial cleanup with scrubbing using bleach and germicidal solutions. Support staff treat the isolation rooms with the double treatment and robots disinfect the operating rooms overnight. So far tests have shown a complete eradication of the superbugs with these methods.

Breaking the chain of infection

Since about 2005 the major food production animals have been shown to be colonized with superbugs (MRSA) as this publication shows.

With 80% of the world’s production of antibiotics still going into the agroindustry for weight gaining purposes, it is high time that international “laws with teeth” apply. The WHO needs to get action in this and the public needs to put pressure on politicians to achieve this. Medical history has shown that infectious epidemics can be cured by breaking the chain of infection. In the example regarding superbugs the story of interrupting the chain of infection is exactly the same here: As shown in this study from Stanford University MRSA bugs are not contained in organic foods. So, by attempting to eat 100% organic, which can be challenging at times, you can intercept the infectious cycle involving MRSA and other Superbugs.

Attempt to eat mostly organic foods

You do not get exposed to the meat from food production animals treated with antibiotics for growth purposes. In the meantime, you are protecting yourself by keeping fit, taking vitamins and supplements all with the hope that the immune system stays strong from this. By eating organic meats and meat products you also keep your body free of toxins that would weaken your immune system and set you up for getting autoimmune diseases down the road.

The end result is that people who follow this example avoid colonization from exposure to superbug-infected meat products.  At the same time this prevents exposure to other toxins that a manufacturer of organic food can not use. Here is a story of a company that produces meat products without antibiotics (organic meats).

Conclusion

You can interrupt the infectious cycle of superbugs by eating organic foods. Make sure your immune system is strong by exercising, supplementing with vitamins and minerals. Wash your hands with soap and clean water, particularly after handling meat or meat products. Do not take antibiotics for a long time unless there is a specific reason of  bacterial infection that requires it. Do not consume meats from animals that were fed antibiotics. Read food labels!

Ginseng Lowers Risk For Common Cold

In Chinese medicine the ginseng plant has been widely used. Its history in North America seems to be shorter at first glance, as it received more attention only, as Chinese medicine and acupuncture have become popular over the last decades. The Asian variety of ginseng known under its botanical name as Panax ginseng is only one of the species. There is however a variety which is native to the eastern part of the North American continent with the botanical name Panax quinquefolius. The first people using it were various Native American groups. They found it useful for childbirth and fertility. It was also used to help those with shortness of breath.

Ginseng root was considered the more valuable part of the plant, and new research has found that root extracts of the North American ginseng have an influence on the immune system. The substance enhances the production of interleukin and interferon-gamma. The immunomodulary effects which can help in the prevention of respiratory disease have also been studied in clinical trials involving older adults.

It turned out that the likelihood of developing acute respiratory illness was significantly lower in the group that was treated with a standardized formulation of 200 mg ginseng extract twice a day than in a group that did receive placebo or no treatment. It was also observed that the number of patient who had common colds was reduced in those who received ginseng. The absolute risk reduction of recurring common colds was 12.8 % and the total number of days with cold symptoms was 34.5% lower in the treatment group.

Long term studies are still outstanding, but based on the interim findings ginseng extract taken in the winter month can be beneficial especially in the older population as a weapon against respiratory illness.

Gene Identification Helps To Screen for Diabetes Risk Of Juvenile Diabetes (type 1 diabetes)

Gene therapy is the new buzzword in a hope for cure of disease, and genetic tests also assist in predicting the risk for disease.

These predictions are reaffirmed by research that comes from McGill University in Montreal under Dr. Constantin Polychronakos, a professor of pediatrics and human genetics. A new DNA chip has been used for testing the genetic makeup that produces diabetes type 1 (also called Juvenile Diabetes). So far the analysis has confirmed four previously identified genetic locations that contribute to the development of diabetes 1, and the test identified a new location occupied by the gene.

With the research team working on the discovery of all the remaining genes, they are confident to develop a test which will predict the risk of developing diabetes. According to Dr. Polychronakos the findings will influence future treatment options. The most promising treatment for those already diagnosed with diabetes1 are stem cell regenerative treatments, such as islet transplantation, since the Langerhans islets are responsible for the production of insulin in the pancreas.

Gene Identification Helps To Screen for Diabetes Risk Of Juvenile Diabetes (type 1 diabetes)

Family tree for inheritance of type 1 diabetes

These therapies will only work if the immune system is also treated, so the patient does not suffer a relapse of the disease. Once all the diabetes genes are identified, there will not only be fast screening but also therapies that can be targeted more effectively.

Dental Signs Indicators for Celiac Disease

Celiac disease is a condition, where a person is unable to tolerate wheat products. In other words they have a wheat allergy. It is not enough to avoid the standard foods like bread and other bakery goods that contain wheat. Wheat makes its appearance in many foods and also in taste enhancers like monosodium glutamate. Alone for this reason it is important for a person with celiac disease to carefully read labels in order to avoid foods that contain gluten, which is the offending substance. Often celiac disease goes undetected for many years, but there are early signs that can help to take action sooner rather than later.

Dr.T.Malahias, D.D.S., a dentist from Groton, Conn presented his findings at a recent international symposium for celiac disease. He pointed out that there are signs that are visible in the dental enamel, which will already be present in childhood, once the permanent teeth appear at about age 6. The bilateral symmetrical markings are defects in the tooth enamel. they can be brownish, yellow or white and are most commonly seen on the central incisors. They give the tooth a mottled, non-shiny appearance. Patients with this appearance may also have problems with the delayed eruption of the permanent teeth. These markings are permanent, and even after following a gluten-free diet they will stay, as the development of the enamel started already in the third or fourth month of life. While there may be other reasons for this abnormality, celiac disease should be considered in the context of the patient’s history.

Dental Signs Indicators for Celiac Disease

Dental enamel defects may be the only signs of celiac disease

The results are quite significant in pediatric groups: in patients less than 12 years of age who had celiac disease the rate of enamel defects ran at 90% as compared to 44% of the others without celiac disease. People who have recurrent unexplained aphthous ulcers should take notice too. Five percent have been found to have undiagnosed celiac disease as a result of the constant and chronic overstimulation of the immune system by gluten substances. Once celiac patients start with a gluten-free diet, the ulcers will occur less frequently.
