ScienceDaily (Jan. 27, 2008)Vitamin D Deficiency Study Raises New Questions About Disease And SupplementsLow blood levels of vitamin D have long been associated with disease, and the assumption has been that vitamin D supplements may protect against disease. However, this new research demonstrates that ingested vitamin D is immunosuppressive and that low blood levels of vitamin D may be actually a result of the disease process. Supplementation may make the disease worse.In a new report Trevor Marshall, Ph.D., professor at Australia’s Murdoch University School of Biological Medicine and Biotechnology, explains how increased vitamin D intake affects much more than just nutrition or bone health. The paper explains how the Vitamin D Nuclear Receptor (VDR) acts in the repression or transcription of hundreds of genes, including genes associated with diseases ranging from cancers to multiple sclerosis."The VDR is at the heart of innate immunity, being responsible for expression of most of the antimicrobial peptides, which are the body’s ultimate response to infection," Marshall said."Molecular biology is now forcing us to re-think the idea that a low measured value of vitamin D means we simply must add more to our diet. Supplemental vitamin D has been used for decades, and yet the epidemics of chronic disease, such as heart disease and obesity, are just getting worse."The comprehensive studies are just not showing that supplementary vitamin D makes people healthier." http://www.sciencedaily.com/releases/2008/01/080125223302.htm[Journal reference: Marshall TG. Vitamin D discovery outpaces FDA decision making.

Obesity is not a disease,
As for there being an epidemic of heart disease - I have yet to be convinced that this actually exists. Yes, lots of people are dying of heart disease, and most of them in the past would not have lived long enough to die of heart disease. Is there any evidence that people who do not die of infectious diseases (i.e. those diseases that now are curable which were commonly fatal in the past) are any more likely to die of heart disease than they ever were. True, in the past, many more people died of other diseases so they never got around to dying of heart disease; but what is also established is that people are not generally dying younger, so the increase in heart disease is not generally the case of people dying of heart disease before they would have in past times they would died of something else, but rather that they are not dying of the things they used to die of, and so are living long enough to die of a heart attack.
Certainly, overdosing on any vitamin is bad for you, just as underdosing is. ..... and thus the inference still remains that the risk of underdosing on vitamin D exceeds the risk of overdosing on vitamin D for young children.

That is a very stupid statement by the professor.Talk about dumb.Does he really think only vitamin d is the ONLY factor in heart disease and obesity?Does he really think only vitamin d is the ONLY factor in heart disease and obesity?The study is wrong or flawed or corrupt.If it is corrupt then simply follow the money trail and the reasons will become clear.It is universally agreed exposure to the full summer sun for between 15 to 30 minutes will generate 10000 to 15000 iu of vitamin d in the human body.Further exposure causes vitamin d to degrade and thus reach a production plateau.The question arises why are the people in the equatorial regions who often wear little clothing and exposed all day/most days to the sun not dead from immuno suppression?Why are those near naked tribal in Africa folk not dead from all that vitamin D immuno suppression.Let us go to Spain or Italy or Greece which are fairly sunny and wear people wear minimal clothing.Why are they not dead from vitamin d immuno suppression?Why are they not dying from diseases by the millions?After all 10000 iu daily is a lot more then the paltry 400 iu in vitamin supplements and a huge amount more then in food.After all they are getting at least 10000 iu daily from the sun.The supplements in food are pathetic and very low at levels ranging from 10 to 50 iu per serving.Vitamin supplements usually have about 200 to 400 iu.In other words he is talking rubbish
In my opinion he is a rented expert working for drug companies to counteract and spread disinformation on all the recent research done ...
.... in which 90% reductions occurred in cancers due to vitamin d megadosing.
Rented experts twist research to satisfy their paymasters.
He won’t gain many friends but will gain supplement industry for enemy plus many simple people that have religious proportion belief in miracle property of vitamin D will constantly attack them by misinterpreting his study and spreading misinformation about miracles affect of vitamin D mega dosing.Luka TunjicBiomechanics and Health
Vitamin D As TreatmentHow much vitamin D should one take if they have cancer? We don't know as the research is far from complete. Although vitamin D may help, it should only be taken in addition to standard cancer treatment. It should not be considered a first, or only, treatment but used in addition to regular chemotherapy or surgery. Oncologists and surgeons work miracles every day.Remember, vitamin D may be toxic in overdose, although one expert recently said, "worrying about vitamin D toxicity is like worrying about drowning when you are dying of thirst".That said, many people think "if a little is good then a lot is better". This is definitely not true about vitamin D.http://www.vitamindcouncil.com/cancerMain.shtml...in the meantime, waiting for scientific confirmation, a little bit of 'cod' every day should work just fine.

People have long history of knowledge about positive effect from sun exposure and from importance of intake diversity kind of food.It points that intake of vitamin D to treat disease or other negative health condition is useless in it may be contra productive. It didn’t say that intake of Vitamin D is responsible for increase of chronic diseases like hearth disease and obesity but it point that despite huge increase of vitamin D in recent decades, the incidence and prevalence of chronic diseases are constantly on the rise It shows that your comment is based on your own misinterpretation of this study.Quote from: NobodySavedMe on 10/04/2008 23:03:58In my opinion he is a rented expert working for drug companies to counteract and spread disinformation on all the recent research done ...Pharmaceutical (drag) and vitamin supplements industry gong along with each other.Quote from: NobodySavedMe on 10/04/2008 23:03:58 .... in which 90% reductions occurred in cancers due to vitamin d megadosing.This claim is absolutely unfounded and is hard for me to think that anyone can take it seriously.
Quote from: iko on 13/04/2008 10:43:46Read and meditate first. It is just one of a few similar sentences that you addressed to me in other topics and I didn’t replay before and I don’t intend to replay on such comment in future. If you cant’ face the facts, than is wrong way to tray insult me and flood topic with picture-post that have little or nothing to do with original topic.
Given the variability of intake from food it's not unreasonable to wonder how, when this intake is "supplemented" by UV derived vitamin D the effetcs due to oral suplements are not observed.
Research has suggested certain vitamin supplements do not extend life and could even lead to a premature death. Scientists at Copenhagen University said vitamins A and E could interfere with the body's natural defences. The trials involved 233,000 people who were either sick or were healthy and taking supplements for disease prevention. After various factors were taken into account and a further 20 studies excluded, the researchers linked vitamin A supplements to a 16% increased risk of dying, beta-carotene to a 7% increased risk and vitamin E to a 4% increased risk. http://news.bbc.co.uk/1/hi/health/7349980.stm
Although I like research into vitamins and acknowledge the role that they play in the body, I usually stress to people that natural forms of these vitamins are better than any supplement you could take. Excess vitamins are only necessary in certain conditions, and are only recommended with great caution. Do not take them if you don't know what you're doing!
I was amused the other day when one of the daily newspapers caught on to this idea. They listed food that would supply the vitamins without taking supplements. A fine idea, but for some of the B group they suggested eating fortified cereals.
