The truth that those red meat headlines didn't tell | |||
Dear Reader, If you've ever looked at the New York Post, then you know just how powerful sensational headlines can be. You probably also know how dangerous it is to take those headlines at face value and ignore the bigger story when matters of health come into play. For instance, let me share a headline I came across recently:
Eating high rates of red meat in youth linked to breast cancer
This is exactly why reading the whole article--not just the headline--is so important. So in case you missed the rest of the story, let me fill you in on the details. And explain why this headline is so absurd. The article referred to data from the Nurses' Health Study II--a large, famous study that involved over 100,000 women. And according to researchers, it showed that women who ate less red meat in their adulthood may also have a lower risk of breast cancer. Based on this finding, the media labeled red meat as deadly. But putting outrageous headlines aside for a moment, let's take a closer look to see if that's even a remotely reasonable conclusion to draw. The Nurses' Health Study is practically a household name, due to its vast size and scope. And, indeed, we've collected a lot of vital information from it over the years. But in situations like this, you have to consider its limitations, too. For one thing, it's a prospective cohort study, where women were simply asked to remember what they ate. And that's strike number one. Most people don't journal what they eat every day. And even if they did, there's no way to guarantee they're being honest with their records. (It's far too easy to conveniently "forget.") But we also don't know what else the meat-eaters ate. (I've talked about theproblems with "scientific" conclusions like this before. Sadly, mainstream advice has vilified red meat for decades now--misleading health-conscious individuals to actively avoid it in favor of other "healthier" proteins.
