FDA revisits mercury fillings

An FDA advisory committee is holding a two-day hearing to re-review the scientific basis for the FDA’s conclusion that mercury in amalgam dental fillings is not harmful to patients.

The committee initiated the hearings less than 18 months after the federal agency made the decision. Committee members are examining challenges from four consumer and dental groups that say the FDA used flawed science when it set the guidelines for mercury safety levels. Although the FDA noted there will be no vote on this, they may recommend to reverse the decision and send it to the main FDA board for review.

Amalgam tooth fillings are an alloy of 50 percent mercury, 35 percent silver, 13 percent tin, 2 percent copper, and a bit of zinc. Mercury toxicity was known in the 19th century, but amalgam's cheapness, ease of placement, and durability kept it popular. Dentists argue that mercury fillings last longer than resin composites, and are easier on the tooth. But scientists say mercury is a poison that penetrates into the body and many argue, damages human cells, especially in the brain, bones and kidneys. How much damage is still unknown, which is why the advisory committee is re-visiting the issue.

In their final rule in 2009, the FDA concluded clinical studies have not established a causal link between dental amalgam and adverse health effects in adults and children age six and older. But it did add that developing fetuses and young children may be more sensitive to the neurotoxic effects of mercury vapor.

Today, numerous professional and scientific groups testified in front of the committee, sighting the dangers of amalgam fillings. Studies and testimony presented showed a vast array of connections between mercury in fillings to such conditions as autism to bowel problems.

Dr. Anne Summers, a microbiologist at the University of Georgia who works with mercury, testified that in animal studies, those subjects with more amalgam fillings had higher levels of mercury in their bowels and feces and were found to have more mercury throughout their bodies, than if they had eaten mercury-rich fish every day.

“And they weren’t eating fish,” Summers exclaimed. “They were eating (animal} chow.”

Her studies also looked at the effects of mercury in the body on the gastrointestinal system. Summers noted, “90% of the mercury in the body goes through the lower G-I tract. The gut is very volatile.”

Dr. Mark Geier, President of Genetics Center of America, and founder of ASD centers, published a 2009 study in the journal of the Acta Neurobiologiae Experimentalis ,that looked at the effects of mercury in amalgam fillings on children with autism.

In his testimony to the committee, Geier, an epidemiologist and autism researcher said, “When we examined children with mothers who had zero to six fillings, we saw no significant effect. But when mothers had over six fillings, we found their children had a higher severity of autism, than children whose mothers had fewer fillings.”

Geier continued, “Although we don’t know why the number of fillings made a difference, you have to think of the mercury issue.”

In afternoon public testimony, many people told stories of possible toxic effects on their bodies from amalgam fillings.

Although stories and symptoms differed, all of those who testified asked one thing: Let the public know of the possible dangers in these mercury fillings. In written testimony, Dorice Maderonero, a consultant from the Hudson Valley area of New York, claimed that as a young, expectant mother, she miscarried twice following dental work.

“I know that in my visits to any physician or dentist I was never asked whether I was allergic to mercury.” said Madronero, “And I did not drink coffee, never smoked in my life and didn’t even have a sip of New Years Eve champagne"

Madronero also wrote. “There is very limited to no clinical information available regarding long-term health outcomes in pregnant women and their developing fetuses, including infants who are breastfeeding.” Madronero asked, “Can you really say you (FDA) don’t know and then conclude safety?”

James Turner an attorney representing a group known as “Citizens for Health” addressed the committee, and asked the FDA to update its website on amalgam fillings, particularly on the possible dangers to patients.  “There is plenty of new data showing the effects of mercury in these fillings. We need to ask for safety," said Turner.

But Dr. William Spruill, a dentist from Carlisle, Pennsylvania and President of the Pennsylvania Dental Association, with 5,000 members, believes there's nothing to worry about when it comes to amalgam fillings.

"I've been practicing dentistry for 34 years. I have these fillings, my wife has these fillings." said Spruill. "Based on the research, I am comfortable with my dental work and I would give my kids these fillings, but they don't have cavities."

According to the American Dental Association, "Dental amalgam is considered a safe, affordable and durable material that has been used to restore the teeth of more than 100 million Americans. It contains a mixture of metals such as silver, copper and tin, in addition to mercury, which binds these components into a hard, stable and safe substance. Dental amalgam has been studied and reviewed extensively, and has established a record of safety and effectiveness."

The advisory committee will continue tomorrow. Should the committee decide to make recommendations it will send them to the FDA for consideration. Although the FDA does not have to act on the recommendations, it traditionally follows the guidance of the advisory committees

    If the dentists who make these amalgam fillings must wear gloves, masks, etc while making the fillings, then how are they safe in your mouth?

    Now, they should also review the safety of flouride, which is "scrubbed" from Florida phosphate fertilizer smokestacks and put into our drinking water and toothpaste.

      The gloves, masks, goggles and other protective mechanisms that dentists use are to protect them from YOU – blood, saliva, aerosols, etc. Amalgam does not equal mercury.

      Valerie your retarded. Did it ever occur to you that dentists need to be as sterile as possible when working on patients? and to protect themselves from catching a disease, cold..etc from a patient. Would you want them handling the amalgam with their bare hands before that amalgam went into your mouth?!?
      Of course they have to wear masks, gloves etc. You think they went to school for 4 years AFTER college taking out HUGE student loans to just stick there hands in random peoples mouths?
      And now for fluoride. Did you know since this country started fluoridated water the incidence of cavities dropped DRAMATICALLY?!?! Fluoridated water is NOT TOXIC! You need to get your facts straight.

      Educator, no need to call names. I am not saying that dentists don't need to prevent contamination in all aspects of their jobs, or that they are not hard working individuals. What I am referring to is the protection of themselves from Mercury vapors during the making of the substance they use for these fillings.

      The supposed need for flouride comes from the fact that Westerners eat so much processed food, but the high cost to our health just to clean our teeth from the bad supply of food is not exactly a great trade-off. It is no big conspiracy, just that the excess flouride that used to go towards making nuclear devices now is sent around the country and into our water supply with no hard evidence that it is not toxic to us in the process.

    dentists are not scientists, biologists, neurologists they just stick the stuff in yoyr mouth. They should not have a say on any commitee concearning the saftey of amalgam fillings. They like to talk of all of the successful amalgmam restorations they have done but they dont talk about the other dentisits that have to taket their patient's mercury fillings out becuse they have been getting sick. Science has already proven it is UNSAFE so if any amount of mercuryhas health benefits for the human body show me the data.

      It already has been mentioned that the amount of mercury you get in your body from the fillings would exceed the amount someone would get from eating fish EVERY DAY. Nobody should be eating that much fish. What about breastfeeding mothers? You can't eat fish when breastfeeding, so why can you have mercury directly implanted in your skull?

      Dentists ARE scientists, educators, doctors, researchers, health care professionals etc. They are very active in all those fields. You are underestimating the value a dentist is to the community and to the medical/dental profession.
      Amalgam fillings are the most successful restorative option for cavities. They have been used and tested for decades. Resin composites have a high rate of failure and leakage. Most times patients will return to the dentist requiring a root canal due to the failure of a composite resin. Please visit the ADA's website for information and educational material.
      One additional comment...Some dentists have been working with amalgams for 40 years...repeat 40 years and are perfectly healthy! If amalgams are such a health hazard how come DENTISTS don't show any symptoms???

      Amalgam is considered a bio-hazard waste AFTER its been used for a patient. Once used its considered contaminated from the patients saliva etc. One used it cannot be re-used and needs to be disposed of properly and in a manner that it will not hurt the environment.
      Did you know that once a tooth has been extracted that it is also considered a bio-hazard? And did you ever think that kids put that tooth under their pillow?

      Amalgams are the most successful restoration for cavities period. Resins have a much higher chance of failure and leakage then amalgams. They have been used since the first days of dentistry and are still used today because they are safe, affordable, and successful.

      It is considered MALPRACTICE to remove amalgam fillings because of potential harm to one's health, according to the American Dental Association. So, if a dentist is claiming that they can "cure" a condition by replacing the amalgam, they are not only trying to line their pockets but they are also immoral and going against what our governing body has recommended. Like "Educator" has said, amalgam is the most dependable restorative material we have. Without it millions of under served people would go without fillings and have their teeth extracted.

    Educator,

    Are you kidding me?? You have no idea what you're saying...you have clearly not researched this topic, and yet you are calling people retards?? Please, in the future...do your homework before you start posting and making yourself look like an idiot.

    "Amalgams are the most successful restoration for cavities period. Resins have a much higher chance of failure and leakage then amalgams. They have been used since the first days of dentistry and are still used today because they are safe, affordable, and successful."

    Do you really think people care more about which material is going to last longer?? We're talking about mercury...the second most toxic element on this planet...in our mouths!

    They are still used to today because they are CHEAPER...not because they are safe. They have NEVER been proven safe...which is why this has become such a huge issue. If the filling is toxic BEFORE it's placed in your mouth...and if it is once again toxic AFTER it is removed from your mouth...why would you believe that it suddenly becomes nontoxic while it is sitting in your body? They are successful?? At what...causing disease?

    Also, you mentioned that it only becomes hazardous AFTER it is removed due to contamination from saliva?? So what is the problem BEFORE it's placed into the patients mouth?? In case you didn't know...it's also considered toxic before it ever touches anyone's saliva. It has to be disposed of properly to protect the environment...due to the toxic effects of mercury. HELLO.

    Another thing, there are plenty of dentists who have become sick due to mercury exposure. I have met two of them myself...right here in my area. Dentists also have one of the highest suicide rates of all professions.

    I myself know all too well the dangers of amalgam....considering that I lost my health because of them. It took almost a decade to recover...and while I was disabled and unable to participate in life...I had plenty of time to do LOTS of research. The scientific evidence is overwhelming.....eventually these fillings will not be used..and they are already being phased out. I wonder why that is, if they are as wonderful as you seem to think??

    The fillings don't last a lifetime...mine were deteriorating after about 25 years. During those 25 yrs they continuously leaked mercury into my body...even moreso as they were falling apart. I lost my health because of it. I wouldn't call this a "success". A successful filling would be one that doesnt cause tremendous pain and suffering to the patient. Just saying.

    Again, please get the facts before you start insulting people. When you're done learning about mercury, I hope you will also educate yourself on the dangers of flouride. Sure, it's nice to not have cavities, but I can accomplish that without the use of a toxic substance. And yes, flouride is a known neurotoxin...as is mercury.

There is so many wrongs in your drawn out response that I don't have the time or the patience to explain further. One thing I will explain the levels of fluoride or mercury used in dental practice or oral hygiene is NOT toxic. Do you look at the active ingredient in toothpaste? It's fluoride! Are you going to tell me that billions of people are exposed to a neurotoxin called fluoride everyday!?!? Morning and night???
      One question...have you ever had shrimp or any seafood? I really hope for your sake it's no because there's more mercury in that then there is in amalgams.

      Rachel,

      Have you ever mixed up concrete and been able to pull out the water after it has cured? What makes you think that the mercury in amalgam is able to be extracted after a chemical process has fundamentally changed the structure of the metal? The "science" you are taking about is not true science. I know and probably have read many of these "scientific" studies. There has never been a single well designed scientific study that has shown any bad effects resulting from dental amalgam.

      The reason amalgam is a biohazard before it is placed is due to liquid mercury. Once the amalgam is mixed and cured that liquid mercury is gone, bound chemically to the other metals. After a restoration is removed it is considered a bio-hazard because it has come into contact with a patient's bodily fluids and is thus considered a hazard.

      I agree that you should question doctors because we do make mistakes, but this topic has been discussed and researched extensively and nobody has been able to show there is a problem with amalgam. Anecdotal evidence, like your personal problems, are not scientific. We, dentists, have gone through years of school, studied these topics, and know the processes involved with amalgam condensation. I would hope that every dentists is doing what they feel is best for their patient and not their bank account. Some offices are "metal free" and that is a great solution. If you do not agree with amalgam fillings you have the choice to see a dentist who does only composite restorations, but don't take away something that may be the only option for some people.

    Educator,

    From my experience in having conversations with people regarding mercury in fillings....it is typically those who still have them who are most unwilling to look at the science and who are most in denial regarding it's toxicity. It's human nature. If I hadnt already learned the lesson (the hard way)....and if I still had amalgam fillings in my mouth, while people are out there talking about how toxic they are...you bet I'd be defending them. Thats what we tend to do when something scares us....we tune it out, we deny, deny deny. Amalgam fillings aren't being phased out because they're "safe, affordable, and successful." They're being phased out because people are catching on...and nobody wants to sacrifice their health for cheaper fillings. People are willing to pay more for something that isn't known to be one of the most toxic substances on this earth. It just makes sense.

    Mercury is the second most toxic substance in the world. Mercury poisoning is not studied in the medical college. We have the unhealthiest generation of children, due to mercury exposure. Vaccines containing mercury, Rho-gam immunogloblins, amalgams, fish comsumption, eye drops, ear drops tha contain mercury. Mercury damages the brain, immune system, liver, kidneys, intestinal tract, respitory system. It is toxic to cells, cause allergic reations and mercury poisoning can turn on disease linked genes. We are seeing the highest level of brain injured children and Alziemers disease. Half of our children are on a RX drug for asthma, seizures, learning disabilities or suffer from food intolerances. Mercury exposure is the prime suspect in most of these health issues. The mercury antiseptic merthiolate was banned after a hospital staff used it on umbilical cords in a nusery. This killed ten children and brain injured the other three children from mercury poisoning. This is used in vaccines given to pregnant women and children. The medical community needs to take toxicology in medical school. They are not qualified to be making rulings on mercury.

    Christian DDS,

    Like Educator, it would appear your research is one-sided (and his on both the matters of amalgam fillings and fluoride). A shame. Not very scientific As for the mercury being 'fixed' ("bound chemically") in the amalgam: have you not seen the video of the volatility of the mercury being given off from amalgam? in such close proximity to the brain?? and being swallowed??? In any event: Please be aware that there is more to these two stories than you and Educator are acknowledging. The cause of the case for them is fatally flawed because of one common factor: the corporate one. Follow the money (particularly including the lawyer from the corporate world who got fluoridation going in the federal public health field, and the people who put toxicologist Phyllis Mullenix out of business as an honest researcher, just reporting the facts as she uncovered them). You're on the wrong side of the history past, and of the outworkings of history itself, on this amalgam issue.

    A hint: A dentist in Australia in the '90s developed a sealant for teeth that protected them from decay, thus eliminating the need for both amalgam fillings and fluoridation. Why was this breakthrough not followed up on?

    Indeed.

      Stan,

      I actually don't place amalgam fillings, so I make no money on this issue. I have read the research on both sides, and I know the biology behind the system and this is why I would be comfortable with having amalgam in my mouth or any of my family or friend's mouths as well. Most of these studies are being conducted not by corporate American, but by universities. Amalgam does give off mercury vapor, but only when exposed to relatively high levels of heat. The amount of heat needed to cause the release of measurable amounts of mercury is enough to actually cause damage to the vital pulp of the teeth. Again, if people are so scared of them it is their right to have them removed or not placed. Since there have been no properly designed, non-bias, scientific studies proving that amalgam fillings cause deleterious effects to the human body it is wrong to take a tool away that restores function for millions of people a year who have no problems after placement.

      Fluoride is the #1 public health measure to decrease the most common preventable disease in the United States: dental caries. If the argument of "Fluoride is toxic you shouldn't touch it" works then please never drive your car because gasoline fumes are toxic, don't let anyone you know paint their nails because both nail polish and remover are toxic, and also don't drink water because if you ingest enough of it yes it can kill you. Just about everything in excess is harmful.

      Sealants are a fantastic tool to prevent occlusal (top of your teeth) decay; however, they do not prevent smooth surface decay (decay between your teeth or on the outer surfaces of your teeth). Sealants are common practice, but like composite restorations they fail and fall out even when placed correctly.

      Just as it is your choice to smoke and risk contracting lung cancer or drink and risk getting liver disease it should also be your choice to have amalgam fillings.

      Christian DDS, I am not sure why you would support the studies done by Universities which, after the process by which they receive grants to conduct their research, is not necessarily less biased than corporately funded research. The studies conducted must still match the ideologies of the persons or bodies granting money for said research. And that means support of Flouride, support of amalgam fillings.

    Thank you both, Elaine and Stan!!!
    I think that the public is starting to see that even the medical & drug industries (like most other industries...) are all about profits (MONEY). The FDA is unreliable & corrupt like many of our gov't officials. Thanks to the internet, we can do our own research today.
    Stan & Elaine, please also see Dr. Gupta's article & comments from August – http://pagingdrgupta.blogs.cnn.com/2010/08/05/do-mercury-fillings-pose-a-health-risk/ on CNN's 'The Chart'.
    We have to make sure this issue does not get pushed under the carpet quietly.
    The more people read and know about this the better.
    The late Dr. Hulda Clark was also harassed & threatened by people who did not want her research known. Since she was not seeking financial gain, she published her books without copyright or registered patents, so everyone can make free copies of the material and help other people. She was one of the biggest advocates against metal fillings.
    Since I read her book, followed her advice & removed my metal fillings, I no longer suffer from any symptoms I used to have. I also recovered from psoriasis and thyroid autoimmune diseases that are 'incurable'. I had psoriasis ALL my life… and had to take pills for the rest of my life for my thyroid problem.

      "It has mercury ,it is going to leech. I don't care what you say take any substance and overtime its going to break down. the whole reason they don't take it off the market is it has a whole industry built around it, take that away and it hurts the economy and... blah blah blah "

      Please stay on track to the article and provide your proof that the mercury used in amalgam will start to "leech" at a time/rate ratio that's detrimental to human health within a natural life expectancy? Please tell me you have real scientific proof to back up your claim, other than blind ideological conjecture that so prevelent today.

    I find it insightful that this biased psuedo- scientific article has as it's heading photo an improper full mouth series where the apices of the second molars are not close to being captured (let alone the thirds status). I would not accept that FMX from my assistant. Par for the course of this garbage article from non-experts.

    Pharma is making to much money and is too inbeded in the economy for them to further test and develop,if they haven't already, a frequency generator that could possibly eliminate the need for pills

    Well hillbilleter that's because none of these comments are going to be published or posted in any articles so they don't need a editor but I am sure you feel that much bigger about yourself for putting someone else down about their screw up when you should be looking past that and reading what they have to say if your pride would be so kind and that wasn't even my post you commented on and now here comes your angry self defense mechanism

    in the end they don't care about the average joe besides its a win win for them anyway they get sick people to take care of and contribute further to the medical industry its all one big circle. Alagram fillings have been around how long....ok so all these companies that supply these products to the dentists offices have had plenty of time grow on the market. All these companies have been banking it and order paper, pins, pencils, water, cups and the list goes on and on and on ...now if this company can no longer produce its product because it has been found unsafe and goes out of business or even decides to get in to another business causing it to down size but most likely sell off most if not all offices and buildings all those people lose their job all those companies suppling all their needs and any other partner ships going on all get hurt in the process this also causes the economy to somewhat crash and hurt the stock market because all the for mentioned starts a chain reaction in a lot of different companies. This is how the evil screwed up system is in place and because people stand idly watching and doing nothing because they are to busy with their own every day mess and because their is no kindness and softness of heart we cannot all be millionaires because we all won't help the person next to us at the same time their is enough money in this world for everybody but because of greed and money means your better we all get stuck in this dog eat dog world someone else has to suffer somewhere so that this person can have a dozen houses and cars

    Wow! These posts definitely show diversity, however, there is always one right answer. The problem is getting the right answer. I feel bad for those of you who put so much trust into organizations such as the ADA, and all other associations and organization that claim to be for the safety of the people. With all due respect, its time to get educated and wake up. These people and most in our government today are not about what is best for the people. They are looking out for their own political agenda and their pocket book. I'm not saying this by mere opinion, but after research. That is the reality. If you look further into the ADA and the information we are discussing, you will see the reailty of the "trusted" ADA. Same goes for agriculture and the rest of so call "government protected" organizations. If you are going to research, first, you need to make sure the research is legitamate. Second, you have to look at both sides objectively. I too used to be so naive to think that these organizations that are created for our protection were actually protecting us. Boy, after lots of research, I have realized that America used to have great intentions, but lost their way a long, long time ago. Its no longer we the people.

    "Mercury is a component of the amalgam used for "silver" fillings. The other major ingredients are silver, tin, copper, and zinc. WHEN MIXED, THESE ELEMENTS BOND TO FORM A STRONG, STABLE SUBSTANCE. The difference between bound and unbound chemicals can be illustrated by a simple analogy. Elemental hydrogen is an explosive gas. Elemental oxygen is a gas that supports combustion. When combined, however, they form water, which has neither of these effects. Amalgam's ingredients are tightly bonded to each other. Although the types of chemical bonds in water and amalgam differ, saying that amalgam will poison you is just as wrong as saying that drinking water will make you explode and burst into flames." – Stephen Barrett, M.D., Quackwatch

    A had a stroke; I believe it's mercury fillings. I was hypotensive, dehydrated, lethargic and weak. I was on a monitor bed with a catheter, IV's and a shockingly low blood pressure at 63/28. It's 1999. Not good.

    Christian DDS, Unfortunately I had a dentist like you who put amalgams in my teeth as well as that of my parents and sister. Now that we analyze, we were perfectly healthy till our contact with amalgams. Soon after we all had brain fog, forgetfullness and a host of other illnesses that we did not relate to the mercury since the doctor insisted it was safe.
    For Dave and others that ask proof, let me tell you this. My sister had all her tests done that showed normal health and a normal functioning thyroid. About a week later amalgam from one of her teeth came out while eating which she accidentally swallowed. The next week she had intense weight gain sweating etc. A visit to the doctor and some tests later she was diagnosed with hypothyroidism. I had amalgams in me for 20 years. After removing them and chelating for 2 years, my brain fog and lot of other illnesses are gone. I did not dream it all, my reports show healthy levels of blood pressure, cholestrol etc. I m an engineer myself. I ask how can something be harmful before it goes into your mouth and after it comes out? And all that discussion about mercury becoming inert in an amalgam is pointless. Our bodies have acidic/alkaline environemnts. There are so many things that we eat that can combine with the mercury and other metals and enter the GI tract. And do you really want to put such a toxic substance inside you, what if it falls off and u eat it accidentally?
    Sorry , I wont wish this on anyone but next time someone in your family needs a filling doctor, please fill in with amalgams and see for yourself. We didnt have to be doctors to learn a thing so simple.

    Thanks for another fantastic article. Where else could anybody get that type of information in such a perfect way of writing? I have a presentation next week, and I am on the look for such information. Robbin Goal http://www.robinhoodchina.info

    Wow. I havent read or "heard" from either "Christian DDS" or "Educator" in some time, guess they read for themselves the health concerns online... kinda hard to keep denying when literally 100s of other websites are proving them dead wrong and sadly lowering my confidence in those whose desire is to care for us (of course docs do make pretty good $, could be a better intent.

    I dont know about everyone reading this but just a couple days of simple internet research has shown that mercury in almagams is extremely toxic and poisonous and that sensitivites to mercury poisoining mimic sypmtoms of candida overgrowth, they propogate and support the candida. Please if you are suffering from the symptoms of mercury poisoning and candida understand your candida cannot be cured without the removal of the mercury/heavy metals. Find a good Nutritionist and stay far far far away from "doctors" and dentists that deny and say these fillings are safe. My experience is this. Doctors/dentists certainly have their place, but you cannot force them to care so much about your problems to the point where you will get an accurate diagnosis. The proper diagnosis is everything. Doctors are so quick to use the "cutting edge" technologies and practices that they are ingnorant to the true powers of natural remedy, they are actually defending against the need for it at all. This is evident in our nations clinics.

    I have been to well over 12 doctors in the past years for the same symptoms. I was prescribed antiboitics, prednisone, given steroid shots, misdiagnoses are as follows... first they thought i dad poison ivy, then scabies, then bedbugs, then eczema, plus a few others I dont want to mention, but constantly given pharmaceutical drugs that were actually making my problem much worse. Now, due to my own research, and literally no help at all from my doctors...except i was given advice to take a stronger antihistamine (which only masks the main problem) I am finding more and more connections between mercury/heavy metals and candida overgrowth. If candida is a word that is new to you please research it and see a nutritionist... whatever you do NEVER listen to people like educator and christian, they sound like bandwagon consensus medicine sheep to me. How sad that you cant even connect the dots when they are stamped all over the internet. If you guys were true doctors your focus would be on healing, diagnosing, not defending a worthless debate that has been proven over and over again by not only time but the internet as well. Certain scandinavian countries have actually banned amalgam fillings... but i guess those vikings are clueless when it comes to health of their citizens (thats sarcasm btw). In my experience doctors are great for treating symptoms and when surgery is needed... however, best try and diagnose yourself as I promise you most of them do not care as much about you and your health as you do. Understand you are not alone.. peace

    PS I wonder if educator or christian have ever suffered the symptoms of mercury poisoning... ever suffered hives? Psorasis? Joint pain, chronic upset stomach, ibs, bloating, leaky gut, itchy anus, fatigue... the list goes on and on... If youve never suffered these i promise you will not be as empathetic toward those who do which is certainly evident in your posts... you both were more concerned about being right i dont think i learned a damn thing from either of you. respectfully. However, the sufferers who posted taught me things i didnt know and just solidified what i already knew... as for you two... how sad..

      You wrote a whole big bowl of stupid here. Just because you read a bunch of hogwash on the internet doesn't make it true. If you can't cite a peer-reviewed study to back up your claims, then don't bother posting a novel.

      And by the way: "Empathetic" doesn't mean what you think it means, dear.

      How shamefull. Your giving vocabulary lessons to people who are suffering. I wouldn't wish these pains on anyone but I would just for a day for you so that you would see. Just because you are educated does not make you intelligent
