7 Medical Myths Even Doctors Believe

medical myths, myths, mysteriesDo you believe that hair and fingernails grow after death? Do you think that humans use only 10 percent of their brains? Do you believe eating turkey makes you drowsy?

Or, how about these commonly repeated beliefs:

  • You should drink eight glasses of water per day
  • Shaved hair grows back faster, thicker and darker
  • Reading in dim light ruins your eyesight
  • Mobile phones are dangerous in hospitals

Then you’ve bought into some very common medical myths which, while widely held, are simply untrue, says this study published in the British Medical Journal.

To read more of these myths, and find out the truth behind them, take a look at the link below.



Dr. Mercola Dr. Mercola's Comments:

Here’s another example of why you can’t blindly believe everything medical experts tell you. While I can certainly agree with some of these myth busters, I cannot support all of them, and some are just not sufficiently or appropriately explained. 

Not All Expert Advice is the Right Advice 

Take this myth, for example: You should drink at least eight glasses of water per day.  

Here they claim as “fact,”  

“Over the years, “fluid” turned to water. But fruits and vegetables, plus coffee and other liquids count.” 

Hold it right there. Coffee counts toward your daily fluid intake?

Every day you lose water from the body through urine and sweat, and this fluid needs to be replenished. Coffee is a natural diuretic, which – logically, I might add – depletes your body of fluids.

Your body is equipped with a mechanism that tells you when you need to replenish your fluid supply -- it’s called thirst! So although I have stopped recommending drinking a specified amount of water per day, fulfilling your body’s request for fluids by drinking coffee is simply not going to do the job.

Without going into all the negative health ramifications that can be attributed to coffee (which I’ve reported in many previous articles, all of which you can find on my site), let it suffice to say that not only are they completely overlooking the fact that coffee simply cannot replace the biological benefits of plain water, they also fail to answer the question of: if not eight glasses of water, then how much water do you need?

Setting the Record Straight on the Water Myth

We know you can exist without food for months, but without water you can only survive for a few days. Your body is made up mostly of water, which:

  • Is essential for digestion, nutrient absorption and elimination
  • Aids circulation
  • Helps control your body's temperature
  • Lubricates and cushions joints
  • Keeps your skin healthy
  • Helps remove toxins from your body

I have refined my recommendations to this: use the color of your urine as a guide to how much water you should be drinking.

As long as you are not taking riboflavin (vitamin B2), which fluoresces and turns your urine bright yellow (it is also in most multi-vitamins), then your urine should be a very light-colored yellow. If it is a deep yellow then you are likely not drinking enough water.

Of course, if it’s hot outside or you are engaged in exercise or other vigorous activity, you will require more water than normal so be sure to stay well hydrated in these cases. Additionally, as we grow older our thirst mechanism works less efficiently so older adults will want to be sure to drink water regularly, and again make sure their urine is a light, pale color.

More Myths Most Conventional Experts Fail to Inform You About

The myths studied and “clarified” through science in this article are not really a matter of life and death however. Fortunately, believing in them will not necessarily ruin your health in the long run.

But there are many other medical myths out there that are actually taking lives because even your doctors fail to realize they are perpetuating a myth and giving out misguided advice.

Here are a few more of my top medical myths that you REALLY need to know the real answers to:

Myth: Sun Exposure Causes Skin CancerThis is perhaps the most pervasive and destructive myth in today’s society, reinforced by expensive media campaigns for sunscreen protection of all kinds. Unfortunately, that trend is contributing to one million unnecessary deaths each and every year, causing about 600,000 deaths from breast and colorectal cancer alone.

Can sun exposure cause skin cancer? Absolutely -- if you burn. However, appropriate sunlight exposure actually prevents more than 16 types of cancer, and provides benefits such as promoting the formation of vitamin D, which many folks are very deficient in.

You also need to know that using sunscreen is NOT a good way to limit your sun exposure; in fact, sunscreen is one of the last things you want to put on your body, and sunblock does not stop skin cancer.  

As natural health expert Krispin Sullivan explained during my interview with her last year, when you wear sunscreen you may not realize you’re creating sun damage because it prevents you from burning – but the damage is still being done on a cellular level -- simply because now you’re staying out in the sun too long, thinking it’s okay since you’re covered in goop. Adding insult to injury, sunscreens contain many toxic chemicals that can cause additional problems in your system, and increase your risk of disease.

Myth: Milk Does Your Body Good – Another case where back-in-the-days before pasteurization, this was true. However, commercial pasteurized milk is not healthy for your body, and should be avoided if you want to be optimally healthy. For a great explanation on the differences between healthy raw milk versus pasteurized milk, don’t miss Mark McAfee’s excellent video on this subject.

And, of course there is the issue of the hormones, antibiotics and pesticides that are used in modern milk dairies, and the fact that nearly all commercial dairy cows are raised on grains, not grass, like they were designed to. This changes the composition of the fats in the milk they produce, especially the CLA content.

Myth: Whole Grains are Good for You --  Even though I do agree that whole grains are better for you than refined grains, whole grains are still not healthy for most people. Why? Because so many Americans are either:

  • Overweight
  • Have high blood pressure
  • Have high cholesterol
  • Diabetics

Nearly everyone with these issues has high insulin levels, and would therefore benefit greatly from avoiding all grains -- even whole grains. Additionally, about one-third of people will need to avoid grains because they are protein types.

Myth: Fish is Good for You – Again, prior to the industrial pollution that has now devastated the waters world wide, this was true. But not anymore. Fish (and shellfish) easily accumulate very high levels of chemical residues from the water they live in. Residues in fish can be as much as 9 million times the amount found in the water!

Sadly, due to the release of 40 TONS, or 80,000 pounds, of mercury into the air and water each year, this once healthy food has now been rendered largely unfit for human consumption. Some of the contaminants now found in fish flesh include:

  • Mercury
  • PCBs
  • Radioactive substances like strontium
  • Toxic metals such as cadmium, lead, chromium and arsenic

Fortunately, there are still some viable alternatives for obtaining the nutritious benefits of fish, such as regularly consuming high-quality purified krill oil or fish oil. Some wild Alaskan salmon are also still good, as well as very small fish like anchovies and sardines.

Myth: Saturated Fat Causes Heart Disease – I recently published an article about this very topic. If you missed it, I’d recommend reading it in its entirety: The Truth About Saturated Fat. Saturated fats from sources like meat, dairy, some oils and tropical plants such as coconut actually provide a concentrated source of healthy energy in your diet. They also:

  • Provide the building blocks for cell membranes and a variety of hormones and hormone like substances
  • Slow down absorption so that you can go longer without feeling hungry
  • Act as carriers for important fat-soluble vitamins A, D, E and K.
  • Are necessary for the conversion of carotene to vitamin A, for mineral absorption, and for a host of other biological processes

Part of the scientific confusion relates to the fact that your body is capable of synthesizing saturated fats that it needs from carbohydrates, and these saturated fats are principally the same ones present in dietary fats of animal origin. However, and this is the key, not all saturated fatty acids are the same. In fact, there are more than a dozen different saturated fats with subtle differences that have profound health implications, and if you avoid eating all saturated fats you will suffer serious health consequences.

There is still a link between fat and heart disease. But it’s most likely dangerous TRANS FAT, and not saturated fats that is the problem and the missing link between fat and heart disease.

Regarding skin cancer:  Drugs and toxins cause skin cancer, not sunlight.  Two years ago I had a little skin cancer from Zyprexa (which I ignorantly took for a couple months).  I quit the toxic drug and the cancer stopped growing.  Then I took turmeric.  In two days of eating turmeric, the skin cancer completely vanished.  And this was while I was sunbathing, every day!

No, sunbathing DOES NOT cause skin cancer and probably helps heal it.  And it toughens your skin gradually to make it more sun-tolerant.

I believe this was on Newstarget last week.

Why not address the allopathic myth, then /i'd believe the article more.

i think it is interesting, but i disagree with the water thing, espcially with the crap some people eat, they need plenty of water. I mean even i eat fairly decent, but i drink quite a few more than 8 glasses a day.

The unit of measure is cup.  What's a glass?  Anything from a NY 4 oz to a Texas 16 oz. could be a glass.  Water is dangerous.  A local TV station had a contest to see who could drink the most water.  One woman died from drinking too much, although she won the contest and the TV people got fired.  Dr. "Batman" who wrote the book on water used it as medicine when he lived in the desert countries but does not recommend such large quantities. I hope you don't drink the water that comes in plastic, or reclamation water, but writing to you has made me thirsty....excuse me....

I dont think you should avoid canned salmon for example!  I think the benefits outweigh the risks and especially the risk of ingesting a tiny bit of mercury.  You can find information that mercury in the air is more harmful than mercury in small trace amounts in food or water.   This is simply not high risk unless you are pregnant or very very young and still in the development stage !!

berry lee, I think it may depend upon your own mercury threshold. If you are currently in mercury detox, then all potential sources should be avoided. The problem is, no one knows what level of mercury in our bodies will begin to manifest health issues. And some bodies are better at eliminating heavy metals than others. I'd rather be safe than sorry.

Nothing new here.

So called rationalists, who says they live their life according to Reason, and profess not to believe in intuition, you know, that kind of things are so 'irrational,' seem to just love publishing articles like this on a regular basis. They also seem to love to call themselves skeptics, as in 'I don't believe in anything that humanity has been living by for millenia unless you can prove it to me beyond the shadow of a doubt that it is true.'

Fine, I say.

My old, science teacher used to say to us class: "If you don't believe in Nature, Nature can't believe in you." Which was his way of saying: if you don't believe that luck exists, well, you are out of luck!!

For instance, the critiscism about the 10% of the brain "theory" is typical of those folks. At any given time, we are using very little of our brain, less than 4 or 5%. That's probably too New Age for them 'reasonable' folks who believe that humans are so superior to the rest of The Universe. Truth is extremely few activities we do actually engage the  total brain. Which means brain functionning is generally unbalanced. We are either too analytic, or too general. Etc. For instance, the vast majority of people behind bars have been found to have 'functional holes' in their brain: many area of the brain never get used, the neurones simply don't fire, and there is little blood flow. This is due, in part, to all the poisonous foods those people have to eat. This article is just distorting the scientific findings of the last two decades.

Actually SamVed, did you not read the whole article?  "But MRI scans, PET scans and other imaging studies show no dormant areas of the brain, and even viewing individual neurons or cells reveals no inactive areas, the new paper points out."

Thank you Aziegler for the advice. I will check out the books. I have personally found that soy does not have all the health benefits that we have been led to believe. In fact, I am allergic to it, and it has no place in my diet. The Natural Health magazine was the current issue, and it amazed me that there is still so much controversy about saturated fat.  

 I hope everyone will excuse me if I make mistakes in my questions. I have read this forum for quite sometime, and have found it very interesting, but this is the first time I have ever participated.

Thanks again for the responses.  gramma bea

Back in the early 1970's I used to love sun exposure, then the myth about skin cancer turned me against it.

But now thanks to Dr Mercola's advise on this website, I am returning to exposing my body to the rays of the sun as I used to many years ago: it turns out that my early instinct was right and medical "science" was wrong !

"SPECT brain imaging: This view of the human brain illustrates a highly variable, abnormal pattern of blood flow. Brain blood flow is related to the degree of neural activity, and hence, brain function. [...] brain activity in specific areas is greatly reduced compared to controls. Areas of chronic dysfunction (functional lesions) appear as "holes" in the brain. Dysfunction often occurs in the prefrontal areas of the brain (top of image), and thus may be expected to cause significant loss of impulse control, decision making, learning ability, and emotional stability."

The picture and comments above (hmm, I don't know if the site is going to post it, let's see.....) were taken at random from a simple search on the internet. I can't scan the pictures I have in my office  because they are enormous.

As I have posted previously, the article in Medical Myths" is just distorting the scientific findings of the last two decades. I've seen hundreds of scans of brain activity, done with all current technologies. The article can only be considered true if you live in the 19th century. Or if the authors have some corporate interests to protect.

Also, I'd like to suggest a recent piece in the Los AngelesTimes, December 5, still available I think at http://www.latimes.com/news/opinion/la-oe-amen5dec05,0,6407609.story
titled 'Presidential candidates' health is a campaign issue. So what about their brains?'

I only use non-aluminum baking powder to raise my bread, no yeast.  Aluminum has been linked to alzhiemers and other memory disfunctions. I use only non-brominated wheat flour.  I do not use white sugar, I use wildflower honey, and I use virgin olive oil, and garlic salt.  This combination seems to keep me pretty healthy and eating good.
