The healthiest people are the most iodine deficient

16. November 2009 William Davis (19)
Here's an informal observation.

The healthiest people are the most iodine deficient.

The healthier you are, the more likely you are to:

--Avoid junk foods--30% of which have some iodine from salt
--Avoid overuse of iodized salt
--Exercise--Sweating causes large losses of iodine.

So the healthy-eating, exercising person is the one most likely to show iodine deficiency: gradually enlarged thyroid gland (in the neck), declining thyroid function. Over time, if iodine deficiency persists, excessive sensitivity to iodine develops, as well as abnormal thyroid conditions like overactive nodules.

Even subtle levels of thyroid dysfunction act as a potent coronary risk factor.

    So should a healthy person like me, who isn't big on salt, doesn't eat junk food and exercises regularly, be concerned about a potential thyroid problem? Seems paradoxal.

    Thanks

    I believe I am one of those 'healthy' people....Last year I started doing what Dr. Guy Abraham suggests...I built up to 50mg of iodine by taking drops of Lugol's Iodine for 3 months. Then slowly reduced the dose to a maintenance dose of 2 drops/12.5 mg. per day.  I also follow a protocol of taking magnesium, B complex, selenium, Vit C, and make sure I get enough Vit D3 mostly from sun (Florida).  In your opinion do you think that 12.5 mgs iodine is a safe dose to take indefinitely.  (I also use some other supplements: fish oil and bio-indentical Progesterone...)  I am a 56 yrs old female.

    On May 20, 2009 you wrote "My sense is that the Recommended Daily Allowance of 150 mcg per day for adults is low and that many benefit from greater quantities, e.g., 500 mcg. What is is the ideal dose? To my knowledge, nobody has yet generated that data."

    In looking for a convenient way to confront my Iodine situation, I realized that I might have on in my backpacking equipment. I use Polar Pure iodine based water disinfectant, which produces a 4 to 5 ppm solution of iodine in water.  This is effectively 1 mg of iodine in an 8 ounce glass. So, taking a glass every day or so would put me in the ballpark of the 150mcg and 500mcg that you mentioned.

    It is free, because I already have it, and I am skilled in the use from many backpacking trips.

    There are cumbersome urinary tests to assess for iodine deficiency, but they are rarely used and are fairly unreliable, since they tend to reflect short-term intake, not overall adequacy.

    You've left with a situation much like vitamin C: You'll know you're deficient when your teeth fall out. For iodine, it will be thyroid dysfunction.

    It's NOT worth waiting to find out. Everyone should supplement iodine in some form unless, like MaterialGuy, you get it somehow already.

    If interested in supplementing iodine, it would seem prudent to get a baseline thyroid level, supplement, and see if it changes for the better. I plan to do this next month, starting at a smallish dose (250-500mcg).

    I was a bit skeptical as to dosing iodine, until I read Dr. Davis' recent article for LEF (nice article, by the way) where he recommends 500mcg up to 1 gram, if I remember right. That seems like much more reasonable dose to me as compared to Lugols, etc.

    I was also under the false impression than an iodine urine test would be accurate, but it doesn't seem like it would be. A loading test might be a bit more accurate, but that also sounds like a pain to get.... and no insurance would probably pay for it either.

    Only other thing to consider is form. Kelp could have some impurities (especially arsenic), so potassium iodide the preferred form to take?

    I've read that Lugol's drops or Idoral tablets are good forms to take because they are Potassium Iodide and Iodine. One can make their own Lugol's with ingredients from science companies or off ebay:
    5 gm iodine
    10 gm potassium iodide
    100 ml of distilled water
    yields 6.3 mg Iodine per drop

    I am currently reading a book called "CLEAN" by Dr. Alejandro Junger.

    In it he says many of the same things you say, and ties in many problems we suffer, like thyroid issues, etc. to the condition of our bowels and inflammation.

    I would like to read your opinion of this book if you ever get time to review it.

    Thanks!

    Hi All: I believe I am a perfect example of the case. Since very early age, 16 y o, I was diagnosed with hypertension.
    In my early 20s I started to read about salt restriction, exercise and heart disease. By age 35 I started to act "different" though I continue to exercise 4 hours a week, low fat-low salt diet.
    I started to have "panic attacks" when in certain situations. Then in the early 90s I was diagnosed with goiter and started taking hypothyroid drugs. The "attacks" went away.
    I believe all this was a low iodine diet that affected my life for many decades. Today, I still have hypertension and hypothyroidism but all under control. I also take Iodine.
    supplements.

Cardiology Confidential

Cardiology Confidential

11. June 2008 William Davis (9)

Okay, so it's a shameless knockoff of chef Anthony Bourdain's titillating Kitchen Confidential.

But the confidences that I've heard whispered in the corridors of health involve something more provocative than how your food was prepared. Any service for humans performed by other humans is subject to the idiosyncrasies and weaknesses of human behavior. That's just life.

In healthcare for your heart, the consequences can be more profound than eating three day old fish on Monday's dinner menu.

Over my 15 years practicing cardiology in a variety of settings in three different cities, I've witnessed just about everything from shocking to sublime. Some of it speaks to the extraordinary commitment of people in healthcare, the unexpected courage people show in the midst of illness, the devotion of family in difficult times. It can also speak of mewling, sobbing carryings-on over the most minor conditions, the meanness that emerges when people are frightened, the vultures circling just waiting for Grandpa to kick the bucket and leave his will declaring the spoils.

For the most part, my cardiology colleagues are a hard-working bunch committed to . . . Uh oh. I was going to say "Saving lives, preserving health." But that's not true. Once upon a time, it was true for many of my colleagues, often revealed over $2-a-pitcher beer-softened, "we're going to save people" conversations in medical school. Ahhh, medical school. I remember walking along the street alongside my medical school in St. Louis, bursting with pride and a sense of purpose.

But, for many of us, something sours our purpose through the years. Maybe it's the smell of money, maybe it's the series of distasteful experiences that show that healthcare providers are, in the midst of health crises, the innocent recipients of anger, frustration, disappointment.

Whatever the genesis, the stage is set for an imperfect scenario that pits healthcare provider against patient in a less-than-perfect system.

This would read as a mindless rant if it wasn't based on such pervasive and pravalent truths, tales of the flawed deliverers of healthcare driven by motives less lofty than "saving people."

Take Dr. S, a doctor who performs a large number of procedures on patients. I'm told he is very capable. He manages an extraordinary amount of heart work--in between jail time for wife beating and Medicare fraud.

Or Dr. C, well-known in the region for his procedural talents, also. Usually acerbic and freely-swearing, he opens up engagingly when drinking--which is most of the time. Paradoxically, as is true for some serious drinkers, he works more effectively while intoxicated.

Or Dr. ST, who proudly admitted to me one evening over dinner that he has accepted 6-figure payments from medical device companies on a number of occasions to use their products.

Or the manic ups and downs of Dr. J, who refers just about every patient he sees for emergency bypass surgery when in his down phase, mangles coronary arteries in daring angioplasties during his up phase.

How about 310-lb Dr. P, who hounds her patients about indulgent lifestyles? That would be excusable as innocent lack of self-insight if it weren't for her propensity to use heart procedures on patients as punishment. "I have no choice but to take you to the hospital."

Dr. M. manages to maintain the appearance of straight-and-narrow during the day, all the way to attending church twice a week with his children. His daytime persona effectively covers up his frequent visits to prostitutes.


We are ALL flawed. My colleagues are no different. But some circumstances cultivate the flaws, fertilize corruptibility, reward it. Such has become the state of affairs in healthcare for heart disease. Why? Is it the excessive potential for money-making that existed until recently? Is there something about the save-the-day mentality of heart disease that attracts imperfect personalities looking for the adrenaline-charged thrill but morphs over time into near-psychopathic lives?

It's not the end of the world. The fact that my colleagues' behavior has reached such extravagant lows signals a bottom: things are about to change.

In the meantime, let me tell you a few more secrets . . .

    It is absolutely time for us to wake up to the fire-fighting mentality of the larger medical community.  Sometimes treatment and intervention is necessary, but the focus of medical attention ought to be on Prevention in the most natural way.  Dr. Davis thank you for getting that message to us.

    Recently I came across another book, with a title that might be too strong for some, but it does reflect a very sad, flawed, state of affairs:  "Genocide: How Your Doctor's Dietary Ignorance Will Kill You!!!!  By Dr. James Carlson.

    What I have found funny is the large # of people that feel the need to defend hospitals or the practices of  doctor.  It doesn't seem to matter what political persuasion a person is, many just seem to have a need to believe the marketing hype that America has the very best doctors and medical care available, and that doctors always have your best interests at heart.  You don't find this kind of loyalty for other industries.  I often thought this high level of trust is caused by Hollywood shows.  Ever since we were little kids many Americans have been bombarded with movies and television programs glorifying doctors and hospitals.

    I befriended my daughter's pediatrician's wife and learned then and there about how imperfect people are.  I learned of his depression and family alcoholism.

    Since my celiac diagnosis (and despite my daughter's medical history he didn't diagnose her as being on the autism spectrum - but that's another story), I've learned so much and have shared with her my thoughts about sugar, grains, carbs etc, which have been scoffed at.  I have all but diagnosed HER son because they have not been enlightened.  It's not appreciated.  And she shared with me about other doctors' lives as well.  What you say is true; you need to be in that culture to know more truths for your own safety!

    BTW, I enjoy living vicariously through Chef Bordain and wonder about his lipid panel ... he smokes and gets out of breath easily.  When the time comes, I wonder what medical advice he'll get.  Knowing him, he won't care.

No more canned foods

No more canned foods

21. September 2008 William Davis (12)
If you haven't already caught the news, it's time to eliminate canned foods and exposure to plastics that contain the chemical, bisphenol A (BPA). A worrisome and unexpected association with heart disease and diabetes has been found.

This issue has been debated for some years ever since scientists at the NIH detected BPA in the blood samples of 93-95% of Americans, with consumer protection advocates calling for more research or even the outright banning of BPA , while industry representatives have argued that the data fail to conclusively prove adverse health effects.

Well, the argument has been tilted heavily in favor of increased consumer protection with the publication of a study in the Journal of the American Medical Association by Dr. Iain Lang and associates at the University of Exeter, UK, and the University of Iowa. Their study, released Sept. 17, 2008, Association of urinary bisphenol A concentration with medical disorders and laboratory abnormalities in adults, persuasively demonstrated a 40% increased incidence of coronary heart disease, heart attack, and diabetes with increasing exposure to BPA (as judged by urine levels) among the nearly 1500 adults aged 18-74 years. People with coronary heart disease had double the blood level of BPA compared to those without.

In addition, higher urine levels of BPA were associated with abnormalities of two liver tests, GGT and alkaline phosphatase.

Interestingly, although much of the debate over adverse health effects of BPA have centered around concern over cancer and reproductive risks, an association with cancer did not hold. (No analysis for reproductive issues was conducted in these adults, since most of the concern is for children exposed through polycarbonate baby bottle use. Some BPA critics have raised questions like low birth weight developing from exposure.) No relationship to thyroid disease was identified, also.

The editorial accompanying the study added some sharp commentary:

"Subsequent to an unexpected observation in 1997, numerous laboratory animal studies have identified low-dose drug-like effects of BPA at levels less than the dose used by the US Food and Drug Administration and the Environmental Protection Agency to estimate the current human acceptable daily intake dose (ADI) deemed safe for humans. These studies have shown adverse effects of BPA on the brain, reproductive system, and--most relevant to the findings of Lang et al--metabolic processes, including alterations in insulin homeostasis and liver enzymes. . . For example, when adults rats were fed a 0.2 microgram/kg per day dose of BPA for 1 month (a dose 250 times lower than the current ADI), BPA significantly decreased the activities of antioxidant enzymes and increased lipid peroxidation, thereby increasing oxidative stress. When adult mice were administered a 10 microgram/kg dose of BPA once a day for 2 days ( a dose 5 times lower than the ADI), BPA stimulated pancreatic beta cells to release insulin."

This study, piled on top of the worrisome literature that precede it, are enough for me: No more tin cans (which are lined with BPA), no more hard plastics labeled with recycling code #7 or #3, no more polycarbonate water bottles (the hard ones, often brightly colored). Microwaveable-safe may also mean human-unsafe, as highlighted by this damning assurance from the Tupperware people that BPA is not a health hazard.

The National Toxicology Program also issued these advice in response to the Lang study to reduce BPA exposure (reported by the Washington Post) :

· Don't microwave polycarbonate plastic food containers. Polycarbonate may break down from overuse at high temperatures and release BPA. (Manufacturers are not required to disclose whether an item contains BPA, but polycarbonate containers that do usually have a No. 7 on the bottom.)

· Reduce use of canned foods, especially acidic foods such as tomatoes that can accelerate leaching of BPA from plastic can linings. Opt for soups, vegetables and other items packaged in cardboard "brick" cartons, made of safer layers of aluminum and polyethylene plastic (labeled No. 2).

· Switch to glass, porcelain or stainless-steel containers, particularly for hot food or liquids.

· Use baby bottles that are BPA-free; in the past year, most major manufacturers have developed bottles made without BPA.

    Sort of related, but in a "canary in the coal mine" sense:  the lining in pop-top canned food has long been suspected by veterinary researchers of being a likely cause of hyperthyroidism in cats (a very common feline illness that often strikes multiple cats in a household, therefore pointing to an environmental cause).

    So this warning includes only liquid products in tin cans and hard plastics labeled with recycling code #7 or #3?

    I hope so, because avoiding all hard plastics in general would be nearly impossible.  Almost all water, milk, yogurt, juices, even  organic products, fish oils, and some pharmaceuticals come in hard plastic containers.

    Oh well, so much for my beloved Bumble Bee canned wild Alaskan pink salmon and my canned pureed tomatoes.

    I wonder if there is a source anywhere so we can look up what companies have eliminated BPA's from their canning process or not.
