Comments on: Surprising Study: Put Down the Vitamins & Free the Free Radicals http://blogs.discovermagazine.com/80beats/2009/05/12/surprising-study-put-down-the-vitamins-free-the-free-radicals/ Mon, 22 Apr 2013 21:34:00 +0000 hourly 1 http://wordpress.org/?v=3.4.2 By: nutritionist brisbane http://blogs.discovermagazine.com/80beats/2009/05/12/surprising-study-put-down-the-vitamins-free-the-free-radicals/#comment-8468 nutritionist brisbane Wed, 29 Jun 2011 01:58:44 +0000 http://blogs.discovermagazine.com/80beats/2009/05/12/surprising-study-put-down-the-vitamins-free-the-free-radicals/#comment-8468 This is based on a very small sample and short trial period. As far as we can tell from the abstract, what the subjects ate during the trial period were also not known. In contrast there is a great body of research on the positive benefits of antioxidant supplementation. This is based on a very small sample and short trial period.

This is definitely something new to me, had not heard about this before. Looks like I should reconsider taking all those supplements I bought.

Who cares about more insulin in physically fit athletes? And as for natural antioxidant defenses, those endogenous antioxidant enzymes like glutathione, superoxide dismutase and catalase, no, they didn't need to be switched on because the supplemental antioxidants were doing their job. Endurance athletes smash their red blood cells and sometimes become anemic. But vitamin E helps to prevent this. The best diet could not possibly meet all the nutritional demands of athletes for optimal performance. This is a twisted interpretation. Who cares about more insulin in physically fit athletes?

No doubt this study's finding will be subject to additional research. It's important to recognize that there are additional uses for antioxidants, such as the gels many dentists use to assist healing following certain procedures for gum disease. That's particularly important to people who have diabetes because of the interactions between elevated blood sugar and gum disease. We write extensively about related issues at http://dentistryfordiabetics.com/blog, especially the links between blood sugar levels and gum disease that can interfere with diabetes control and significantly increase risk of serious health events. - Charles Martin, DDS Founder, Dentistry For Diabetics Interesting article.

The shape of the curves is also significant. I would guess that the reality is akin to: 68% do about the same with or without,, 16% due better with supplements and 16% do a lot better without. Let's round both 16% off to 1/4. Now we really need to ask ourselves what is the response to any one of many more stressors--say 10. Then if there is no cross-correlation, although 1/4^10( or 1 person in about a million) will always do a lot better without supplementation, 999,999 out 10^6 will do better or no worse with supplementation. It's not the doing not as well in the iron man triathlon that will kill you; it's the doing not as well in one of the other 9 stressors that will kill you. (at least for that ~999,800). (not sure about the exact number that would do worse (rather than the same) to at least one of the stressors--but since I rounded 1/6 to 1/4 and who knows how many stressors and since I don't really have the data, I'm not going to worry about exactly how many would do worse ON AT LEAST 1 OF THE OTHER STRESSORS. But the badly formed test wouldn't answer any of these questions anyway.) Even if there is only one stressor, if the shape of the curve is such that a few do a lot better without, then the average will also be skewed. Amplifying.

Lipoic acid is produced by the body and is the main one of those natural body defenses. The main thing I found wrong with the study is: They found no improvement in insulin sensitivity; BUT they found no improvement in insulin sensitivity ACUTELY. For all they know, a little improvement now (in the non-vitamin takers) will translate into lowered improvement in insulin sensitivity later. And indeed it isn't improved insulin sensitivity that we all need; it is maintained insulin sensitivity. Having said that, I stopped taking Vitamin E in doses about 200 mg/day years ago because it made me feel crappier than usual. By the same token, I don't stop taking supplements because i also feel crappier than usual when I do. So bottom lines: No improvement in body's natural defenses--SO WHAT? there's already enough with the supplemented C and E. No improvement in insulin sensitivity. WRONG; NO improvement in ACUTE insulin sensitivity. Stan:

Every couple of years there is a study that promotes the health benefit of some product. A couple of years later there is another study that shows that product is not so beneficial. Atleast that is how it seems in retrospect. Personally I do occasionaly take a multivitamin, but I'm not particularly good at keeping a regime for it. I find these situations some what comical.
