Newsday.com – Health News/Science News Has anyone but me noticed that the story about many of these vitamins changes from one thing to another then back again over and over?
People who take high doses of vitamin E with hopes that it may protect against heart disease and cancer may want to reconsider. A seven-year study following thousands of people over 55 found that the antioxidant offered no health benefits, and could, in some cases, increase the risk of heart failure.

I think what they’re trying to tell us is that they have no idea what’s going on.
Don’t eat eggs, because of cholesterol, but do eat them for the protein… etc.

My boss has an old photograph of a bunch of professional cyclists smoking cigarettes. Back several decades it was thought that smoking enlarged your lungs, which in turn gave you more endurance.
My boss keeps the picture to remind himself that science is never certain. I.e., what’s certainly true today will almost certainly not be tomorrow.
Figures….Sigh….
Just goes to show you, eat whatever you want. You’ll be happier and it won’t make a bit of difference.
Read the fine print:
“The people they selected were already sick.”
Heh. You guys are starting to sound like the Creationist crowd.
“Science is never certain!”
It says high doses of vitamin E.
Don’t you notice that the letter after “Vitamin” changes with each announcement? The NIH and research community are probably going through them one-by-one so that the supplements industry can no longer plausibly claim: “Buy our pills, and take 1000% of the RDA, just to be safe.”
If Oprah (or Joe Jackson) says one thing, and a scientific study comes out saying the opposite, that is not science contradicting itself.
Same, especially, for coaches and sports trainers. I’ll pay $1000 to anyone who finds a peer reviewed study that ever said smoking increases your lung capacity.
(I’m serious. This would be a lot more interesting than “Find the Diploma” challenge. I won’t reduce the reward to something less painful, but anyone else with faith in the scientific method who wants to defray the cost could pitch in. But it’s gotta be after 1950ish. That seems fair given that the “back-and-forth” we’re talking about is alledged to have happened in our lifetimes, if not just the last 20 years.)
what’s certainly true today will almost certainly not be tomorrow.
Give me a break. First cholesterol is bad. Then they find out that there’s good cholesterol and bad cholesterol, and everyone says “they’re contradicting themselves”. That’s progress, refining your results. That’s Einstein expanding on Newton. Newton wasn’t wrong, he just didn’t have the whole picture.
Balance is the way, grasshopper.
OK. It’s 60 seconds later and I’m chickening out. How’s that for waffling!
The problem isn’t that science says one thing, and then the opposite. The problem is that the Press and the Public interpret the results of ONE study as “Science says X”. Most scientists want “verifiable, repeatable results” from multiple, if not dozens, of studies, before they’ll even entertain the notion of “saying X”.
So the premise of my bet was flawed. I apologize for all the dollar signs flashing before your eyes.
Here’s a general rule for predicting harmlessness vs harmfulness, at least for vitamins. A, D, E, and K are fat-soluble vitamins, which means that they can accumulate in slow-to-dissipate reservoirs in body tissues. The B complex, C, and basicly every other vitamin but the ADEK four, are water-soluble, therefore do not accumulate in body tissues because they stay in the bloodstream where they are available for speedy elimination by the kidneys.
A, D, and K have long been associated with known hypervitaminoses, syndromes of toxicity from intake of too much vitamin. E is accumulating evidence of such a syndrome, but should be suspect simply because it shares lipophilicity with A, D, and K. None of the hydrophilic vitamins, on the other hand, are known to cause toxicity. Take more than your body can use and you urinate the excess away harmlessly. You may spend a nice piece of change just to turn your urine dark, but at least you won’t hurt yourself by taking mega-doses of the B vitamins, or vitamin C.
