The dark green leafy truth about your kale smoothie

I’ve been slacking again, sorry! No post on Monday and I had plans to write a post debunking this article about how kale is killing us all that a friend sent me over the weekend. My immediate reaction was that if kale is accumulating these toxins then it stands to reason that many other vegetables are, as if people need any discouragement from eating their veggies. My friend responded that it would be best if everyone stuck to corn dogs. Of course, that’s no solution as corn dogs are full of GMOs and carbs which we all know cause “grain brain”. Anyway… I was going to dig a little deeper but before I did, I saw this article by Julia Belluz that did that for me so, please, go read her article about how faulty the “science” is behind the headlines that kale is a killer. Sure, alliteration is a great literary device (possibly my favourite), it makes for great headlines, but it doesn’t make bad science good.

There are just a couple of things I really want to emphasis that Julia just touched on. First, despite what the articles indicate, this was not a strong scientific study. There was no true control group. There was no randomization of participants. This was a very small “sample” of 20 self-selected individuals who went to Ernie Hubbard for “detoxes” for myriad inexplicable medical complaints. Ernie started with the assumption that kale was causing their problems, he didn’t seek out other causes. His finding that they were all kale consumers was a self-fulfilling prophecy. Second, Please, please, please don’t stop eating vegetables because of these sensational headlines. The benefits from eating vegetables far outweigh any real risks. Variety is an essential part of any healthy diet so be sure to consume a wide variety of vegetables, including leafy greens and members of the Brassica family, such as kale.

  1. I really like your articles and find they are very informative and well researched. But your statement about gmos makes it sound like it is an ingredient rather than a production method, similair to what organic is (though it has morphed into a marketing tool). If I misinterpreted what you meant I apologize, but if I didn’t and you have concerns about them there are tons of great resources that provide factual info on them.
