Note: This post is participating in an "RD Blogfest" in honor of National Registered Dietitian Day (March 11) I read many online articles, forums, message boards, Q & A, and the like. Too often, I am frustrated by what I read by bloggers, parents, and journalists about nutrition. I have seen blanket advice to supplement kids' diets with unnecessary vitamins and supplements; advice for pregnant moms to take 2 regular vitamins instead of one prenatal vitamin; and advice to breastfeeding moms to take unsafe amounts of herbs to increase their breast milk. I could go on and on. The running theme is that the advice usually doesn't hold water. Much of the advice on the internet is not grounded in research, but rather folklore, feeding nonsensical nutrition advice that will forever be ingrained on the world wide web.
I am bothered when people advise others to take vitamin supplements or herbs without taking into account their diet or health status. It's important to see the whole picture. And I am really bothered when the reason that poor advice is given is that someone is trying to sell you something or increase their Google search hits.
Food vs. Supplements:
Here is a Registered Dietitian's review of some good journalistic articles from February and March 2009 explaining in simple language the results of of some recent research about vitamin supplements. I hope I can convince you to focus on food rather than supplements, and to seek out advice from qualified health professionals.
- A research study showing that kids who don't need vitamins are usually the one who take them anyway. The article states that the AAP does not recommend supplements for most kids over the age of 1.
- Dr. Sanjay Gupta's view on vitamins supplements emphasizing that there is no research proving supplements help make you healthier.
- Postmenopausal women saw no health effect from multivitamin in a recent study.
- This article questions the safety of nanoparticles in vitamins and the lack of oversight by the FDA.
- Multivitamins don't help prevent cancer or heart disease in this study.
- Prenatal vitamins don't contain the amount of iodine they claim to contain according to this report .
- Too much supplemental vitamin E might cause heart defects according to a recent study .
- A good review explaining how some anti-oxidants can act as pro-oxidants if taken in supplemental form.
The RD recommendation:
Get your vitamins, minerals, and phytochemicals in their natural form from food, not pills, unless you can't (eg: health reason or food restrictions). If you think you might need to supplement your diet, ask a Registered Dietitian to help you.
