Vitamins and mortality

Thread rating:  |
Peter Moran - 06 May 2008 05:41 GMT A recent Cochrane review of all relevant prospective randomised controlled trials showed no beneficial effect on death rates from antioxidant vitamins, and possible increased mortality from Vitamin A, Beta carotene and Vitamin E supplementation.
These are unremarkable findings. They confirm a trend in nearly all the quality studies published in recent years. The apparent benefits of a high vitamin intake seem to be more strongly associated with a good diet than with supplementation.
Yet this report has been met by a frenzy of denial and accusations of unscientific behaviour by many "nutritionists" and alternative supporters. The main accusation of these amateur scientists against the renowned Cochrane collaboration is that the authors excluded studies in which no subjects died. This shows a complete misunderstanding of the nature of the data being looked at. There are at least 26 other Cochrane reviews examining the influence of antioxidant and vitamin supplementation on diseases ranging from cataracts to gastrointestinal tumors. This specific study was designed to ask whether antioxidant supplements have any effect on *overall mortality*. So, of course it was reasonable to exclude studies in which no subjects died, in either the intervention or the control arms of the trials. Such studies could not contribute data relevant to the question.
Quote from the abstract- "Background
Animal and physiological research as well as observational studies suggest that antioxidant supplements may improve survival.
Objectives
To assess the effect of antioxidant supplements on mortality in primary or secondary prevention randomized clinical trials."
And a summary of the study from the Cochrane site ---
No evidence to support antioxidant supplements to prevent mortality in healthy people or patients with various diseases. Previous research on animal and physiological models suggest that antioxidant supplements have beneficial effects that may prolong life. Some observational studies also suggest that antioxidant supplements may prolong life, whereas other observational studies demonstrate neutral or harmful effects. Randomised trials have largely been neutral. We need evidence from randomised trials to decide if antioxidant supplements should be used for prevention. The present systematic review includes 67 randomised clinical trials. In total, 232,550 participants were randomised to antioxidant supplements (beta-carotene, vitamin A, vitamin C, vitamin E, and selenium) versus placebo or no intervention. Twenty-one trials included 164,439 healthy participants. Forty-six trials included 68111 participants with various diseases (including gastrointestinal, cardiovascular, neurological, ocular, dermatological, rheumatoid, renal, endocrinological, or unspecified diseases).
Overall, the antioxidant supplements did not seem to reduce mortality. A total of 17880 of 136,023 participants (13.1%) randomised to antioxidant supplements and 10136 of 96527 participants (10.5%) randomised to placebo or no intervention died. In the analyses of the trials with low risk of bias, beta-carotene, vitamin A, and vitamin E significantly increased mortality. There were no significant differences between the effects of antioxidant supplements in healthy participants (primary prevention trials) or participants with various diseases (secondary prevention trials). Randomised trials with adequate bias control found no significant effect of vitamin C. In some of our analyses, selenium seems to reduce mortality.
The current evidence does not support the use of antioxidant supplements in the general population or in patients with certain diseases. The combined evidence suggests that additional research on antioxidant supplements is needed. The evidence on vitamin C and selenium was not conclusive. Future trials could focus on vitamin C and selenium and should assess both potential beneficial and harmful effects. Conduct of additional primary and secondary prevention trials on vitamin A, beta-carotene, and vitamin E seems questionable, at least in the dosage range examined.
The present review does not assess antioxidant supplements for treatment of specific diseases (tertiary prevention), antioxidant supplements for patients with demonstrated specific needs of antioxidants, or the effects of antioxidants contained in fruits or vegetables. Further research and systematic reviews on these types of interventions are therefore warranted.

Nor should all trans beta-carotene and vitamin A be conflated though while related they aren't the same thing.

If I understand you correctly, supplementation is a very tricky matter that has to be done exactly right, balancing a large number of variables, to get any benefit at all.

Rather that most guidance given is all that good especially the guidance provided by the orthodox authorities isn't worth much more than materials used to line the bottom of the bird cage. It clearly shouldn't be left in the hands of medical professionals, it better left in hands of the public because while some will be misguided by both the med professionals. and the popular press, others will get it right. Some of us out here also have degrees or considerable backgrounds in the sciences.
Nutrition and supplement use is less tricky than stock and bond investing.
I'll grant much of the public is infantile but I include the majority medical providers in that catagory. I just wished they leave the adults alone.

PM It's just an overview of what the available evidence is showing. It spells out where doubt still exists.
And Jeez! ---- explain to me why alternative medicine would not be thrilled to know that a nice, safe, entirely natural and unpolluting diet can do as well as expensive vitamin supplementation. Surely this is proof of brainwashing by the supplement industry -- mostly the same villains who produce pharmaceuticals?

The fluff may be vitamin and anti-oxidant poor food stuffs which contains bacterial genes, algecides, herbacides, insecticides, fungalcides, etc.
The main problem with the fluff is that the stuff is grown on mineral dificent soil. By adding only three minerals, NPK, we can get fluff to eat but the fluff does not contain the nutritional components found in foodstuffs of even 20 years ago. This does not address the mineral deficencies found in our soils, and thus our plants and foodstuffs. Try growing a crop of nearly anything without NPK. You will be very hungry next harvest season.
Combine vitamin and mineral deficiency with poisoning from all the - ides and you have just described nearly all of mankind's dis-eases.
The reductionist's studies of looking at one vitamin at a time, and a synthetic one at that, means you have set the stage for mass ignorance about dis-ease and vitamins and minerals.
One plus none equals disease and death. The vitamins must have mineral cofactors to work, and the minerals need the vitamin cofactors to work.

PM Yet despite these supposed defects, the studies are showing that diet does healthier outcomes than vitamin supplementation..

That is a no brainer as I see it. It has long been know that large doses of "vitamin E" reduces the levels of vitamin K. Recall there chemical structures are similar and most absorption is facilitated some or another mechanism. It is likely these quinones compete for absorption. Further most diets are very low in vitamin K even many professional designed diets. And only a tiny few take meaningful amounts of vitamin K as supplements.

My view is more complex than what you project on to me. Drug companies aren't a 100 percent villians, they are composed of people with mutiple motives, their own interests within the companies and biases.
Second, our diets are polluted, over bred, and over processed. People are given dubious dietary advice by all sorts of groups whether they are ADA or USDA.
Third, I seen the benefits of supplements for aliments the orthodox Doc had very poor drug treatment. Take a look at panic attacks, the Doc will offer some med like an SSRI med yet large dose myo-inositol works as effective as the meds without the adverse drug effects. Or look at GERD that Docs throw PPI meds and motility meds at this condition but alternative medicine instead uses betaine HCL caps to increase to stomach acidtity to prevent reflux and prompt stomach motility. Or take a look at diabetic neuropathy and the value of vitamin E, benfotiamine, and r-alpha lipoic acid. Or consider the value of vitamins K2, D3, and rutin, strontium, and DHEA in the face of osteoporosis.
Sure diet is good. If one eats wild caught deep cold ocean fish, lean non-corn fed beef, no or little grain, no simple sugars, limited fruit, and lots and lots of non-starchy veggies.
The supplement industry has just as much right to brainwash as the pinheads in the orthodox medical field. Of course, the situation isn't ideal and many proposes "solutions" are much worse than the status quo. Nor are all the ideas I've mentioned even much pushed by the supplement industry. I wish they would. Some of these things are use by alternative Doc who know by experience these things can profoundly help.
Fourth, I see what has taken place in other nations and I am not impressed. True other nations have so what better over all health care but still they don't grasp what is truly possible as regards health. productive years, and longevity.
Jan Drew - 07 May 2008 05:25 GMT http://www.sott.net/articles/show/154135-Vitamins-A-C-and-E-Increase-Mortality-O ther-Nonsense-From-Junk-Science
The latest attack on vitamins A, C, E, selenium and beta-carotene comes from the Cochrane Library, a widely-read source of information on conventional health matters. In the paper published yesterday, these antioxidants were linked with a higher risk of mortality ("they'll kill you!"), and now serious-sounding scientists have warned consumers away from taking vitamins altogether. But with all the benefits of antioxidants already well known to the well-informed, how did the Cochrane Library arrive at such a conclusion? It's easy: The researchers considered 452 studies on these vitamins, and they threw out the 405 studies where nobody died! That left just 47 studies where subjects died from various causes (one study was conducted on terminal heart patients, for example). From this hand-picked selection of studies, these researchers concluded that antioxidants increase mortality.
Just in case the magnitude of the scientific fraud taking place here has not yet become apparent, let me repeat what happened: These scientists claimed to be studying the effects of vitamins on mortality, right? They were conducting a meta-analysis based on reviewing established studies. But instead of conducting an honest review of all the studies, they arbitrarily decided to eliminate all studies in which vitamins prevented mortality and kept people alive! They did this by "excluding all studies in which no participants died." What was left to review? Only the studies in which people died from various causes.
Brilliant, huh? This sort of bass-ackward science would earn any teenager an "F" in high school science class. But apparently it's good enough for the Cochrane Library, not to mention all the mainstream press outlets that are now repeating these silly conclusions as scientific fact.
Aspirin Causes a Drop in Erections!
Using this same cherry-picking method for reviewing previous studies, I could find evidence to support practically any conclusion I wanted. For example, let's say that I took a look at 100 studies reviewing the effects of aspirin on erections. And let's suppose I arbitrarily decide to eliminate all the studies involving men, leaving only studies involving women. I could then announce -- with the evidence to back it up -- that "Aspirin Linked with Drop in Erections!" Why? Because nobody in the groups I look at had any erections at all. Sure, they're all women, but that's beside the point. By arbitrarily removing selected studies from my analysis, I can "prove" just about anything, even if it's utter nonsense.
The antioxidant study did the exact same thing by eliminating all studies in which people were kept alive and healthy while taking antioxidant vitamins. Or, put another way, the lead researchers on this study purposely eliminated all the studies involving healthy people, leaving only the studies involving people who were about to die anyway (like the chronically-diseased heart patients I mentioned earlier). Never mind the fact that antioxidants might have actually extended the lives of some of these people by a few days or weeks -- the fact that they died while being treated with vitamins is enough, it seems, to point the finger at the vitamins themselves.
If a suicidal stock broker leaps from a tall building, and you hand him a vitamin C tablet on the way down, then it's obviously the vitamin C that kills him, right? That's the conclusion of this ridiculous study: Take a bunch of patients who are about to die, load 'em up with antioxidants, and tally the inevitable death toll. Then announce, with great fanfare, your findings that "Antioxidant Vitamins Increase Mortality!"
Much "scientific" research is pure fiction
As you can see from this particular junk science study on antioxidants, the credibility of much of what happens under the guise of "science" is now so awful that I often wonder how many pharmaceuticals the researchers are on. These people literally have to be on drugs to come up with such poorly-designed studies (and to have the gumption to announce their results with a straight face, too!).
Turns out I'm not off the mark. A recent survey in Nature found that 20 percent of science academics use mind-altering drugs for non-medical reasons to boost academic performance. That's one out of five researchers engaged in illegal drug use! This is a group that takes more mind-altering drugs than a Southern California hippy parade. And then they turn around and come up with "scientific" studies that lack such credibility, even an intelligent child could see right through them.
Actually, it's worse. Because what we're seeing in this antioxidant study is not merely bad science, but deceptive science. Bad science is created by bumbling idiots mucking around with clinical trial data, but deceptive science is created by people who have an agenda; people who have decided what outcome they wish to create even before the study begins. And that's not real science, folks: That's just subterfuge with an agenda.
Agenda-driven scientific-sounding trickery has now replaced real science in much the same way that politicians' pronouncements of "the economy is great!" have replaced any real talk about the national debt. The truth is no longer relevant, it seems. What matters is whatever they can pull off and get the public to believe. The illusion of science is now being routinely used to push a particular anti-vitamin agenda. And guess who's behind that agenda? Big Pharma, of course. There's no better way to trap consumers in a system of lifelong pharmaceutical treatment than to convince them that vitamins are not merely worthless, but perhaps even dangerous!
The unstated conclusion behind all this, by the way, is that "Drugs are therefore safe." If vitamins are dangerous, drugs must be the safe way to treat disease, right?
Riiiight. Drugs are safe, vitamins are dangerous, sunlight will kill you, water has no health benefits, fresh spinach is dangerous... need I go on? These are the pronouncements of a system of medical idiocy that has gone so far beyond the limits of reason, they've actually fallen off the edge of their own Flat Earth. Next, they'll be telling us that breaking a mirror brings you seven years of bad luck, or that if you keep a lucky rabbit's foot in your pocket, pharmaceuticals will work better.
Because let's face it: When facts are no longer relevant, modern "science" becomes nothing more than superstition.
Additional thoughts
I don't mean, by the way, that all modern science is meaningless. There's still a lot of great science going on these days. But when I see "scientific" studies like the one reviewed here being published in the mainstream media, I have to wonder just how low the scientific standards have become today. One thing for sure: The "peer review" approach to science is a complete disaster. All peer review does is protects entrenched ideas that should have been tossed out decades ago. Peer review is a way for defenders of outmoded ideas to reject new ideas, and thus protect their careers and egos.
Peer review doesn't work. After all, it allows junk studies like the one described here to be readily published. All peer review means is that as long as all the peers share the same illusions (or biases), the paper will be published as scientific fact!
Don't believe what you read in the science journals, folks. At least not without engaging your own brain and thinking for a moment about who's behind the study and what they're trying to accomplish. It's quite clear that on this particular study, the aim is to scare consumers away from taking vitamins. Now ask yourself: Who would that benefit? The answer is rather obvious.
