Study: Some Antioxidants Could Increase Cancer Rates 117

sciencehabit writes "Many people take vitamins such as A, E, and C thinking that their antioxidant properties will ward off cancer. But some clinical trials have suggested that such antioxidants, which sop up DNA-damaging molecules called free radicals, have the opposite effect and raise cancer risk in certain people. Now, in a provocative study that raises unsettling questions about the widespread use of vitamin supplements, Swedish researchers have showed that moderate doses of two widely used antioxidants spur the growth of early lung tumors in mice."

    we should stop putting unnatural things into our bodies that should only be enjoying god's creations

    Yeah, all the great things god created, like Mycobacterium tuberculosis, Clostridium tetani, Variola virus, Poliovirus, let's put all that stuff in our bodies, not those evil vaccine things!

    Everything today will increase your risk of getting cancer, if you tried to live life on a diet that had the least risk of cancer causing agents you would have to starve yourself. Sure maybe this study is right and taking vitamins could increase your risk of cancer but honestly if it wasn't vitamins it could be anything else. Just keep living the life you're living and don't worry about something as stupid as if you took your vitamin A today or not.

    If you're eating in any way sensibly, you should have no need of extraneous vitamin supplements anyway.

    There are certain conditions (either genetic or self-imposed, like veganism) where you don't get all that's required - and then you need to get a nutritionist on the case, not just buy things in dosages you have no clue of and take 100% RDA of on top of your normal diet.

    It's an RDA for a reason. Not only is it a suggested (not absolute) minimum, but also a suggested maximum too. People miss the fact that anything other that can potentially be damaging (there's not been much study into it, but if X amount of a certain vitamin shows that you're healthiest and "plateaus" around that usage, why would you need to take more?) in the same way as lack of it.

    And, with stuff like vitamins, it's not instantaneous results, so you can't correlate it with whether you feel better or not or got sick or not directly. In the same way that it will take you time to notice you don't have enough (say) iron in your diet, it might take you longer to notice that you have too much.

    Your body is a machine that's honed by evolution. Eat well, eat properly, eat what it has evolved to eat (which includes meat!) and the amount it has evolved to cope with. And then you'll be fine.

    "Now, in a provocative study that raises unsettling questions about the widespread use of vitamin supplements"

    I believe that should be worded, "Now *another* provocative study" After all, there's been a continuous stream of these. For whatever reason, the human body doesn't like being dosed with massive amounts of chemically reactive substances, gee, what a surprise.

    You can get the same dose from eating fruit, but that has no known downsides in multiple studies. If you're worried about your health, eat your fruit and veg - like they've been saying forever,

    Heh, reminds me of an oldie, but a goodie -

    All things dull and ugly,
    All creatures short and squat,
    All things rude and nasty,
    The Lord God made the lot;

    Each little snake that poisons,
    Each little wasp that stings,
    He made their brutish venom,
    He made their horrid wings.

    All things sick and cancerous,
    All evil great and small,
    All things foul and dangerous,
    The Lord God made them all.

    Each nasty little hornet,
    Each beastly little squid.
    Who made the spikey urchin?
    Who made the sharks? He did.

    All things scabbed and ulcerous,
    All pox both great and small.
    Putrid, foul and gangrenous,
    The Lord God made them all.
