The dark green leafy truth about your kale smoothie

url-2

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.

Follow Friday: All of the low-carb diet blogs

When the news about the new “low-carb diet is the best long-term weight loss diet” came out I fleetingly considered writing about it. In the moment that I took to think about it, pretty much everyone else had covered it. So… Rather than reinvent the wheel. Here are some links to posts that say pretty much everything I would have said (and then some):

James Fell on Six Pack Abs: New Study: What is low carb good for

Karmal Patel on Examine.com: Is low-carb really the best weight loss diet?

Yoni Freedhoff on Weighty Matters: What I actually learned by reading that low-carb is best study

Julia Belluz on Vox: The one thing you need to know about weight loss and diet studies

There’s more, but that’s probably more than enough reading for now. I’m off to The Canteen for a sandwich. See you Monday!

Follow Friday: Julia vs Gwyneth

url-1

Lots of talk on the twitterverse about Gwyneth Paltrow’s new cookbook It’s All Good. While I haven’t seen it myself, and the recipes therein may be perfectly tasty and nutritious, she’s been slammed for including quackery in her forward. Julia Belluz has an article in MacLean’s detailing what aspects of Gwynnie’s advice are pseudoscience and why these statements are potentially damaging to readers. As I’ve mentioned before, I find it exceedingly frustrating that nearly everyone thinks they’re a nutrition expert and people readily latch on to ideas extolled by celebs. Just because you eat (and seemingly in Gwyneth’s case, this may be an overstatement) does not make you a dietitian.
