Headlines Scream 'Danger' - What’s the Truth about This Week’s Vitamin D Study?
(Alliance for Natural Health) “Vitamin D Warning!” says MSNBC. “High Vitamin D Levels Linked to Serious Heart Condition” says Fox. What could be behind these terrifying headlines?
A new study says that taking excessive amounts of vitamin D may cause atrial fibrillation (AF). The research, presented at the annual meeting of American Heart Association, says that people who take too much vitamin D were 2½ times more likely to develop AF.
Well, not quite. That’s what the media have been saying the study says. But it didn’t. It says that in their study of 132,000 patients, AF was found in 1.4% of the study participants whose levels of vitamin D were normal, and in 3.8% of those whose levels were excessive. But the journalists couldn’t even get the basic facts straight. All the articles contained the same blunder that rendered the data meaningless. Everyone rushed ahead, relying only on the press release or the abstract, where the error originated, without waiting for the study itself to be published in the future.
