Lack of vitamin D linked to whites' stroke death

Vitamin D deficiency is associated with fatal strokes among white patients, but it's not tied to more stroke deaths among black people, researchers announced Sunday at the the American Heart Association's Scientific Sessions in Chicago, Illinois.

Scientists from the Johns Hopkins University School of Medicine professed surprise at their findings, which were based on health records of nearly 8,000 black and white adults.

Whites with low vitamin D levels had twice the risk of dying from a stroke compared with whites with higher vitamin D levels. But the researchers found no increased fatal stroke relationship among blacks with vitamin D deficiency, even though they found black people in the study had an overall 60 percent higher risk of dying from stroke compared with whites.

Previous research has found that black people are more likely to be deficient in vitamin D and to have higher risk of strokes than whites. The lead researcher stressed that further clinical trials are needed to determine whether treating vitamin D deficiency will help lower the risk of strokes among whites.

Other presentations Sunday included how drinking alcohol affects heart bypass patients and a look at the dramatic decrease in smoking over the last three decades.

Light to moderate alcohol consumption by men after coronary bypass surgery showed benefits compared with not drinking, but researchers say the findings did not apply to patients with two specific disorders: left ventricular dysfunction and heart failure.

Italian researchers from the University of Rome La Sapienze presented their study looking at how two to three alcoholic beverages per day– which is considered light to moderate alcohol consumption– affected men who had experienced coronary artery bypass surgery. Using a questionnaire to survey 1,021 men who had heart bypass surgery, researchers found being a light to moderate drinker was associated with 25 percent fewer heart attacks, strokes and deaths than non-drinkers.

Researchers revealed moderate to heavy drinking– about four drinks daily– was associated with significantly higher risk of death in men with left ventricular problems. The lead researcher noted that the study results need to be confirmed over a longer follow-up period using more patients and controlling for more factors.

A long-term look at the smoking habits of one metropolitan area –Minneapolis-St. Paul, Minnesota - found that the proportion of adult smokers dropped dramatically during that past 30 years. Using data from the Minnesota Heart Survey, which includes 3,000 to 6,000 participants ages 25 to 74  in each of its six surveys, researchers revealed these smoking trends from 1980 to 2009:

The number of current smokers dropped by half in both men and women. The largest decreases were among adults with higher income and education; current smokers smoked less per day. Men dropped from almost 24 cigarettes to just over 13 cigarettes and women dropped from over 21 cigarettes to 10; the number of "ever-smokers" - those who had smoked at some point – dropped from 71.6 percent of American men to 44.4 percent and from 54.2 percent of American women to 39.6 percent; men who began smoking regularly were just under 18 years old, and women who started smoking regularly at just under age 18, which is a drop from age 19 over the 30-year study period. It's important to note that the study group did not include ages 18 to 24, or below age 18, a period in which smoking often begins.

The scientific meeting continues through Wednesday.

    Light skin + weak skin = recipe for extreme sun avoidance. Just a little thing I've noticed as both run in my family. It doesn't even have to start out as extremely light skin. The sun avoidance leads to that, but, if I had particularly dark skin, I probably wouldn't have started the cycle of avoiding the sun, then eventually not being able to go in the sun at all. Perhaps the low D and stroke risk could be related through the weak tissues.

      Define weak skin? Are you saying fragile skin? Or are you saying easily burned and won't tan?
      My father is pure Sicilian. He worked in construction outdoors. As a result, he tanned dark as a telephone pole.
      I inherited a fair amount of that, though I don't get QUITE as dark.
      My wife tans well too. But she DOES have fair skinned races in her make-up, such as French and German.
      As an oddity, both of our children are extremely fair skinned, they tan like paper in a fire, not at all, but burn.
      THEY avoid the sun, for obvious reasons.
      Fortunately, they also have a reasonably healthy diet and take nutritional supplements to protect them.
      As far as arterial strength being weaker due to lack of vitamin D, I doubt it. There is no evidence to support THAT.
      That said, for bones to be rebuilt, one needs two things. Calcium and vitamin D. Without vitamin D, the body is unable to use calcium to build bone.
      That COULD lead to a slightly higher level of calcium in the blood, where it could build deposits on arterial walls. That would both stiffen then AND narrow them. Many arteries are not totally blocked by only cholesterol, but also with calcium.
      I suspect there is going to be quite a bit of research on this, as there already have been some expressions of interest previously.
      It would take a bit of time to build a model of this as a disease process, then test to verify that model.

      @Wzrd1 – I was suggesting the tissue weakness as a possible root cause worth investigating, not as a result. For example, a collagen deficiency would make the consequences of sun exposure worse and might also change the mechanical properties of the arteries. Looking for a link here that would explain the different results based on skin type.

      Vit D3 is a very critical element. My D3 is an organic food based form. All of our nutritional products are whole food. 98% of nutrients on the market are USP..simply meaning isolated chemical nutrients. We are the only nutrition company that has a Nobel Prize in medicine. You body was meant to absorb food, not chemicals! That is why after taking most vitamins your urine turns bright yellow...that is your body rejecting the isolated chemicals. http://www.vivatoday.com

    My recent blood work revealed I have very little Vit D in my system. My hair was falling out like chemo patients experience, My joints were swollen like those who suffer with RA, the fatigue caused me to fall asleep at the wheel twice; but I thank God no one was hurt. Lack of Vit D happened over a period of time for me....going to work in the dark and coming home from work after dark. I've been on 6000IU a day for 3 weeks and there is a marked difference. My doctor has me on this dose for 3 months and then new blood work. Why share this; hopefully, to help some other workaholic like me to see the light of day, or at least pop the vit D pills.

      Rhonda and Donb – I also had an extremely low Vitamin D level and my doctor put me on an ultra high dose 10000IU for three weeks and then that dosage twice a week for three months when I go back for blood tests. Don – the reason I, and I assume Rhonda, are on such high doses is because my levels were so incredibly low. The safe maintenance does for a healthy person should not go above 5000IU but for those of us with low levels it is essential that we get that level to normal to avoid the complications and symptoms that Rhonda lists.

      I take more than 5000 iu of Vitamin D a day. My doctor runs blood tests once a year, and level of vitamin D is one of the things that is checked. At 5000 iu a day, my blood levels are still below the median...and there is some question as to whether the median is a good benchmark as medical thought is beginning to consider that most people are low in vitamin D given the change in our lifestyles over time. Nothing I've read...and i've read quite a bit, including literature my doctor has given me...research articles published in reputable journals...indicates that there should be a problem with my taking higher levels of Vitamin D. It does have an impact on mood as well as other aspects of health....I was absolutely amazed at the difference.

    The sun gets too much of a bad rap. Sensible sun exposure generates thousands of times more vitamin d than all the milk you can drink ot tablets you can safely take. What doesn't get utilized by sun exposure gets excreted, unlike vitamin d supplements, which can become toxic if you take too much. Vitamin d is protective against many cancers too. The trick is to not overdo it. A little exposure to keep the d stores high is good, not to mention the great mood it puts you in, imo.

      Tom, I agree that sun gets a bad rap, but sun exposure is not effective for everyone at increasing the blood levels of Vitamin D. In a study by Neil Binkley (University of Wisconsin) 51% of highly sun exposed young adults recruited from a surfing shop in Honalulu, HI were Vitamin D deficient. We don't understand why this is the case, but the safe way to ensure vitamin D sufficiency is to use oral supplements to achieve a serum level of ~60. While a serum level of 30 or above is required to prevent bone loss, a much higher level is likely to be required to ensure proper functioning of the immune system. I like to see my patients with a level of ~60ng/mL or higher. A recent study in a neurological journal published a study on MS patients who were supplemented with 10,000 IU/day of Vitamin D3 (Cholecalciferol) and no one displayed any symptoms of overdose, despite very high vitamin D levels. A safe place to start for adults is 2,000 to 5,000 IU/day of D3. Of note, supplementation and Vitamin D levels should be carefully monitored in people with difficulty with calcium metabolism, kidney disease, and a number of other disease, so you should discuss with your doctor whether it is safe to supplement. Just understand that many doctors in my experience (I have lectured to other MDs on this subject) are not that well informed about its medical benefits.

      By the way, Vitamin D is fat soluble and is not excreted in the urine. Excess Vitamin D is stored in your body fat and released when needed. Excess Vitamin D produced in the skin is broken down by exposure to UV light, thus there is a limit as to the amount that can be produced at any one time in the skin. As mentioned above, this whole process is not very well understood...

    Actually, vitamin D deficiency can be linked to many ailments and diseases. Please google 'Dr. Mercola' and check out his excellent articles on vitamin D. There is a lot of information there on studies that have been done regarding the benefits of vitamin D, especially the natural form derived from getting a few minutes of sun each day.

    If the research used ONLY 30ng/ml as the level of sufficiency the results vastly understate the potential of vitamin D.

    The same DNA-damaging, sunburn-causing UVB wavelengths that sunscreens are designed to block also do some good: They kick off the chemical and metabolic chain reaction that produces vitamin D. Research shows that many people have low vitamin D levels. There is a well-documented relationship between low vitamin D levels and poor bone health. Now links have been made to everything from multiple sclerosis to prostate cancer. “Linking” low vitamin D with these diseases doesn’t prove cause-and-effect, but it suggests that possibility. Getting some sun may also shake off the wintertime blues: Research suggests that light hitting your skin, not just your eyes, helps reverse seasonal affective disorder (SAD). Moreover, being outside gets us golfing, gardening, and engaging in other types of physical activity.

    Nobody wants to get skin cancer, but we’ve gone from sun worship to sun dread. Dr. Stern and others say there is a middle way that includes using a sunscreen with a sun protection factor (SPF) of at least 15 when you’re outside for an extended period and wearing a hat and shirt around midday. So when summer’s here, get outside and enjoy it!

    Hey – before you start taking mega doses of vitamin D – pay attention to your dosing schedule. Vitamin D lasts only about 15 hours in your system. If you go for blood tests after fasting for 12 hours you will always have lower levels of vitamin D. Don't harm yourself with megadoses because you didn't get correct dosing info!!!!!!

      I hate to burst your bubble 'stopbeinglazy', but making sure we all have much needed nutrients in our body is not a "fad". Outside activity and homemade meals will not ensure optimum health I'm afraid. More knowledge of how nutrition works within the body is the key. I have heard many people say how healthy they felt, how they were not on any medications, how they had never been sick a day in their life..on and on...until they got sick....it doesn't happen overnight, it takes years to become sick, without our even knowing it. So if I were you, I would look into what your body is lacking by way of supplements (do the various blood tests etc). and then decide how healthy you are. We can only harm ourselves by ignorance. Liked your last sentence though...the middle way is always the best.

      Wake up call-If most all your food has a bar code or a list of 50 ingredients, aka BK, McDonalds, frozen processed foods, and the like, then you might have some grounds to argue for taking vitamins. The body is more complex than we will ever comprehend, and we didn't evolve along with synthesized vitamins. Whole foods like fresh organic fruits and vegetables have complexity of nutrition our bodies know how to use. Disease vanishes when the body is cleansed with raw fruits and vegetables. I know. We want a fix – a drug, a vitamin supplement, or whatever – something to make us feel better or correct some problem now. And the truth is we are poisoning ourselves with crap food that acidifies our bodies and promotes cancer, heart disease, etc. Just do a search on alkaline foods. Do you think all our obese children just need to take the right vitamins? No – they have been expertly marketed to throughout their lives by the fast food industry. Our kids will live shorter lives than us. Being healthy is simple – eat mostly raw foods, exercise, get sensible sun exposure, and do some form of relaxation technique like meditation, yoga, visualization. I'm 47 and do all that stuff and am in top health physically and emotionally.

    So... vitamin D is primarily obtained two ways. By eating fish oils, and by getting out in the sunshine, where exposure to sunlight causes the skin to produce vitamin D. Perhaps a sedentary lifestyle is actually what is linked with stroke, and this difference is only noted in white people. This would be pretty darn feasible, since dark skinned people must get much more sun exposure to get the same effects as lighter skinned people. Therefore, it seems likely that vitamin D deficiency acts as a proxy for lack of outdoor activity in life in white people, but not in darker skinned people as many more of them are likely to be deficient regardless of leading an active or sedentary lifestyle.

  26. your wake-up call

    Stop with the talk about taking too many vitamins. You can't take too many vitamins. No one has ever died from taking too many vitamins. Not one. Too much Vit A? Impossible. Too much Vit C? Impossible. Your body will just absorb what it needs and then pass the rest through and it'll actually detox you on the way out. The worst thing that can happen from taking too much Vit D is to be a little sleepy the next day. Big deal. If anything is causing low Vit D levels, it's probably from the rise in tick bites aka lyme disease. LD essentially acts to block the absorption of Vit D and low Vit D causes immune dysfunction and you end up with arthritis, thyroid disorders, Lupus, RA, MS, Alzheimer's, etc., and everyone's dying of Alzheimer's it seems lately, aren't they? And who the hell has never gotten a tick bite? Maybe that's why your knees hurt. And, I'm sure the way that people lather on sunscreen (which is full of heavy metals) doesn't help with malabsorption of Vit D too.

    This article should of mentioned that Vit D was just recently discovered to be not only a vitamin, but a hormone too. Pretty cool stuff if you ask me.

    Vitamin D is NOT a vitamin. It is a hormone. Has its own receptor. Engage the receptor, you have a lot of effects that are still being determined. A famous biochemist in Australia, one of the authorities in vitamin D receptor has been calling for caution, because of all the unknown functions of this hormone. One of his arguments is: majority of people in India score low levels of vitamin D, yet they receive plenty of sun. Why? because the organism might be lowering vit D physiologically or in adaptation to another problem. Supplementing with a hormone we really don't know much about may require reassessment of public health policies.

    Let's put a little more effort into R&D with natural supplements, like vitamins instead of spending Billions on poisonious drugs with nasty side-effects.. Lets put people first, profits second in our health care ..

    Interesting discussions. My breast cancer oncologist told me to take 1000 to 2000 units of Vit. D daily. No joke, I immediately felt better. Sort of like the difference between getting a good night's sleep, and getting a GREAT night's sleep. I'm sold.

    • Big Pharma Wants Us Drugged

      Did you know the FDA wants to make all supplements illegal and require a prescription? They are threatened by the fact that many Americans know the facts about Vitamin D deficiency as well as others being the cause of cancers, diabetes, and so on. Thanks to the Internet, we are now able to educate ourselves and choose a more natural approach. Look it up. It will be HORRIBLE if this happens!!! Why do you think the FDA never spends any money testing natural treatments and DEMANDS all vitamins carry the note that 'these statements have not been evaluated by the FDA' yet they will readily give us VIOXX and AVANDIA that kill MILLIONS!!?!!?!

    I heard that Vit. D is metabolized by the Liver–not our muscles–and if you intake too much Vit. D, it will store up and eventually affect liver functioning. Is this true??

      Everything is metabolized by the liver & can cause liver damage when taken in excess.

    I developed Psoriasis almost 20 years ago along with joint swelling and pain. Was diagnosed with psoriatic arthritis and put on some nasty immune suppressing drugs. Not until 2 years ago when I moved out of state did my new doc screen me for Vitamin D. My levels were extremely low and probably had been for many years. Was put on 2000 IU/day and within 3 weeks, I felt so much better it was amazing. I always thought the fatigue and pain were from my "disease", when it really was from "deficiency". My condition is not completely cured, but I can tell that with time, it very well could be.

    I am now quite convinced that the increase in cancers, cardiopulmonary disorders, autoimmune diseases etc are really just manifestations of either an allergic reaction to the additives placed in modern food or the lack of TRUE nutrients due to processing. There is no substitute for farm grown food that was allowed to roam free in the sun and not sprayed with or fed drugs and pesticides.

      This well educated community knows why 300 tablets only cost 10.99. Tablets are not readily absorbed by the human body. However, the toilet sucks those babies down without a problem.

    No!, the researchers clearly stated that the data for blacks was not statistically significant. Their regression analysis lacked enough data after they eliminated those people with "stroke health factors (including diabetes, high blood pressure, cholesterol, body mass index, ...)", which many Blacks have. Also, the report mentions that blacks die of strokes 60% more frequently than whites.

    Actually vitamin D acts more like a hormone than a vitamin. Without vitamin D calcium would never enter the blood stream and patients would soon become suffer from hypocalcemia which can be lead to arrhythmias and be dangerous.But the body has a great defense if the blood is low on calcium it takes it from the bones. Since vitamin D is a fat-soluble vitamin it can be stored in the body and become toxic though few cases have been reported.Doctors do prescribe high doses of vitamin d for short periods of time to patients who are have low levels.

  45. benefits of vitamin d3

    On the topic of Vitamin D I've learned it plays an essential role in the body which is required for the absorption and maintenance of calcium. Having the right levels of calcium in the body enables the maintenance of the appropriate structure within the bones, teeth and proper functioning of the nervous system. This is the major reason why we require the appropriate levels of vitamin D in our body. Vitamin D belongs to a group of fat-soluble vitamins. This means you need to transport the fats.
