Peer-Reviewed Journals continue to cite invalidated studies

Yes, the question remains--as Groucho Marx used to ask--Who do you trust? Seems some medical experts support continue to support their conclusions with data from studies that have long been invalidated in clinical trials. This report says they've proven this so far for at least Vitamin E, estrogen, and beta carotene. Here are the facts on estrogen:

"For estrogen, 61.7% of 47 articles published in 2006 indicated the hormone may protect against Alzheimer's disease on the basis of a 1996 observational study, even though a clinical trial in 2004 found a trend for increased risk of dementia in postmenopausal women taking estrogen. Of the remaining articles, 29.8% were equivocal, and 8.5% were unfavorable. "

Reminds me of the joke about the elephant--each person describes the creature according to how much of which parts he can feel. That's how it is the world of Internet marketing these days, too. What constitutes "truth" can change so rapidly that most people can never catch up to it all.

And we want better from everyone--but especially our medical professionals.

Calcium from food may be better for bone health

I have been waiting for this. Yes, okay, I'm a skeptic about taking fake versions of vitamins and minerals instead of getting them from our diets. So here's this study--not massive, of course--that indicates calcium from natural substances affects estrogen metabolism in a way that may more thoroughly promote bone mineral density.

I predict we will see a lot more of these studies as we discover ever more substances to analyze, and as our ability to measure them becomes ever more sophisticated. It's been well documented for some time that our vegetables have lost significant amounts of nutrition. And now as continue to investigate how important it is to get our nutrition from food, we will begin to see more and stronger connections in how our artificially enhanced soil, chemicals, and other abuses of nature are contributing to our ill health.

This can only be a good thing.
