Back in the "
gold pepper"
story we suggested, based on our experiences, that we all use
Vitamin D in combination to make the effects more efficient. Today we found what we thought was the story concerning the effectiveness of
Vitamin D in the prevention of
breast cancer. The story wasn't from a well-known or respected news source, though we thought it was. We found
the story but the
research seemed to say
something different and we got so excited we didn't know what to do:
"Serum Vitamin D and Cancer Mortality in the NHANES III Study (1988-2006) - Vitamin D has been hypothesized to protect against cancer. We followed 16,819 participants in NHANES III from 1988 through 2006, expanding upon an earlier NHANES III study (1988-2000). Using Cox proportional hazard regression models, we examined risk related to baseline serum 25-hydroxyvitamin D (25(OH)D) for total cancer mortality, in both sexes, and by racial/ethnic groups, as well as for site-specific cancers. Because serum was collected in the south in cooler months and the north in warmer months, we examined associations by collection season ("summer/higher latitude" and "winter/lower latitude"). We identified 884 cancer deaths during 225,212 person-years." - Cancer Research (OnlineFirst)
That's all we can afford, the free abstract, so we don't know the best part that works, for instance, how much worked or needed. The information that we
would need
to speculate might be in the parts of the research to which we
didn't have access. We don't
need to access the full research and we will admit that we sometimes
miss crucial information that won't be found in the abstract. Which is why we often go to the
source institution to find their plain English
press releases on their research that often
isn't in either the headlines or the story.
“Vitamin D Status Is Not Associated With Risk for Less Common Cancers - We did not see lower cancer risk in persons with high vitamin D blood concentrations compared to normal concentrations for any of these cancers,” said Demetrius Albanes, M.D., NCI, one of the study investigators. “And, at the other end of the vitamin D spectrum, we did not see higher cancer risk for participants with low levels.” - National Cancer Institute (News)
Its hard to ignore a thirty-three (
33) year study even if it is from a
US government agency. We don't generally question the
National Cancer Institute (
NCI) of the
US National Institutes of Health. We don't also take their word at face value. We question. We doubt. We check and we
verify. Consider it checked, doubted and verified.
"Researchers and clinicians have looked to the possibility that vitamin D might be used for cancer prevention. Some evidence indicates that higher levels of vitamin D are associated with a lower risk of colorectal cancer, though the evidence is inconsistent. Through the Vitamin D Pooling Project, researchers had access to a geographically and demographically diverse group of men and women, including participants from the United States, Finland, and China." - National Cancer Institute (News)
That's the doubting part that we talked about. The
US found one results and the
Chinese found another with a more diverse albeit smaller group. We think the difference is in the amount of
Vitamin D used to achieve a different result than in America. We aren't scientists and we didn't have access to the full
US results but we speculate that since the
US minimums are substantially different than levels recommended by
US doctors and even
Canadian doctors that matters. It is
speculation. We also admit that. We're not ready to dismiss the power of
Vitamin D which is and has been shown to be effective.
"There appear to be many health benefits associated with adequate intake of vitamin D, including suggestive evidence with colorectal and breast cancers. While the available data are promising, we need to learn a lot more about vitamin D and its potential health effects. We plan continued study of this remarkable nutrient, which will help resolve the many remaining questions." - Nurses' Health Study Newsletter (2008)
Not our opinion but the opinions reached by those with more information and education that all of us combined. We know. This is for those who say the news says one thing one day and another thing the next - you just don't know what to believe. We say you can and you should know what to believe. The news can't give you the nuances that you need to be able to discern your beliefs. We says its in the
math. Number of
years, number of
participants and
amounts given thats the
math you need to know to firm up your beliefs. If you
want to be in the know.
"Randomized trial of vitamin D supplementation to prevent seasonal influenza A in schoolchildren - This study suggests that vitamin D3 supplementation during the winter may reduce the incidence of influenza A, especially in specific subgroups of schoolchildren." - American Journal of Clinical Nutrition (March 2010)
That's the
power of vitamin D just in time for those with grandchildren or children, if you're so blessed,
flu season and fears that the vaccine could harm them. We say don't be afraid and that your fears are largely
unfounded - but we will admit what's true for the majority isn't true for everyone. You have to do what's right for you and your situation.
Vitamin D seems to be, if you're not overly supplementing yourself and family now, the answer to vaccine fears.
The amounts given to the children exceed what the
government says is the
safe high limit for the vitamin. Though the amount given the children
didn't exceed the government limits plus the "
safe upper limit." While
vitamin D can be
toxic what the government
considers recommended levels
aren't the same amounts that professionals
recommend.
"Can vitamin D be harmful? - Signs of toxicity include nausea, vomiting, poor appetite, constipation, weakness, and weight loss. And by raising blood levels of calcium, too much vitamin D can cause confusion, disorientation, and problems with heart rhythm. Excess vitamin D can also damage the kidneys. The safe upper limit for vitamin D is 1,000 IU/day for infants and 2,000 IU for children and adults. Vitamin D toxicity almost always occurs from overuse of supplements. Excessive sun exposure doesn't cause vitamin D poisoning because the body limits the amount of this vitamin it produces." - National Institutes of Health (Consumer Fact Sheet)
We're not
comfortable recommending exceeding levels beyond what the researchers used in their research. We are curious as to
their intentions of the researchers in exceeding the levels in trying to achieve their findings. Again since we
can't afford to access the
entire study we
can't speculate as to what their
motivations might have been. We can
speculate that researchers don't expect government recommended levels to contribute to our overall health. That's what we'd like to see researched.
"Osteoporosis guide to help treat brittle bones - Take 400 to 1,000 IUs of vitamin D per day for those aged less than 50, and 800 to 2,000 IUs daily for those 50 and older." - CBCNews (Oct 12, 2010)
We
weren't comfortable recommending exceeding the
US government's levels but the
Canadian government feels comfortable doing so for those older than
50. The research shows that illnesses and age can be a time where we get comfortable with what we eat which probably doesn't include a wide variety of fresh foods nor much sunlight all of which decreases our
vitamin D levels. When we made our
prior suggestions it was without
full knowledge of the current research though there was plenty of
prior studies that made the suggestion more than likely.
"A recent review article published by Loyola's nursing school researchers concluded that adequate intake of vitamin D may prevent or delay the onset of diabetes and reduce complications for those who have already been diagnosed." - Loyola University Health System (Newswire)
When we buy
vitamin D we go for the
cheapest price rather than for any concern for its
form. Until the most recent research we bought by the
International Unit rather than whether its
natural or
synthetic. We didn't even realize until we made a recent purchase of the supplement that it was available in two (
2) forms. When we sought information from the purchaser we discovered
conflicting information than that available from our government.
"Vitamin D is found in supplements (and fortified foods) in two different forms: D2 (ergocalciferol) and D3 (cholecalciferol). Both increase vitamin D in the blood, but the D3 form may do it better and keep levels raised for a longer time. Many supplements now provide vitamin D3 instead of D2." - National Institutes of Health (Consumer Fact Sheet)
What excited us even further was that the vitamin was
good at reducing children's chances of contracting the
flu. We'd like to
speculate that what would work with
children would also work with
teens and
seniors. That
isn't quite what the study says. The indication is that prior use
might even work against you in the protection department.
"Vitamin D better than vaccines at preventing flu, report claims - Altogether 354 children took part in the trial, which took place during the winter of 2008-09, before the swine flu epidemic. Vitamin D was found to protect against influenza A, which caused last year's epidemic, but not against the less common influenza B." - The Sunday Times (March 15, 2010)
The same way we suggested adding
Vitamin D to "
gold pepper" to make its health effect work efficient and effective when it comes to the
maximum amount of
Vitamin D protection combining
D with
calcium has a more profound and health effect as well. We know you're going to tell us the headline that
calcium use can hurt you but if you read the specifics you'll discover the following:
"Calcium pills may raise heart attack risk - A recent study suggested a link between calcium and heart attacks, so researchers from the University of Auckland, New Zealand, reviewed 11 studies of people taking calcium, without also taking vitamin D, which included almost 12,000 people." - CDCNews (July 30, 2010)
That's true that
calcium is bad for your heart if you
don't take it in combination. Would we
speculate that you should add calcium to "
gold pepper" and
vitamin D? No, not just yet. We need more research to make us take that step. After all
we aren't doctors and review the
news on health and
not the
science as much as what's behind the science. Even if we were doctors its
doubtful that we'd still be likely to make or take the step of making that
speculation. We've been
concerned about reactions from combinations and regardless of the source of the
supplements they're still chemicals. Reactions are still a major concern.
