It’s been 2 weeks since the systematic review and meta-analysis on non-nutritive sweeteners was published. Let’s look at what happened on how it was reported. If you are interested in my interpretation of the July 2017 systematic review and meta-analysis published in the Canadian Medical Journal, which is what these media examples were reporting on, the link is here.

Before I even start explaining what I’ve done here, I want to make it absolutely clear that this analysis is fairly casual, and that by no means have I followed a text-book rigourous protocol to do it because if I HAD done that, you wouldn’t be reading this for another year while it waited in the publication queue of some nutrition journal. However, I will say that even with that disclaimer, I’ve probably been a bit more rigourous than a lot of crap I’ve read, so…well, there really isn’t anything more to say, is there?
Back in the early 2000’s there was a small surge of medium-chain-triglyercide (MCT) research that petered out around 2003ish. While there were a fair number of human trials looking at MCT’s and lipid profiles, there were also a handful of trials that also examined the effect of MCTs on body composition, specifically fat loss. And while MCTs are used in some supplements and meal-replacement shakes, there hasn’t been a widespread adoption of MCTs like there was when olive oil got really big (also in the early 2000’s), and I have to say that it’s not entirely clear as to why. Part of the reason might have been the sparseness of human trials involving MCTs compared to those looking at olive oil. Since 2009, however, there appears to be another blip of human trials looking at MCTs, and specifically at coconut oil, or mixes that involve a fair amount of coconut oil.

I’ve always thought a meta-analysis on beta-alanine was a good idea. So many of the trials have been underpowered, that it felt like weren’t getting anywhere fast. I wanted to be the one to do it, but life circumstances have kept me from focusing on much other than my main career. So it was a pleasant surprise to see that someone else had the same idea.
With just 11 weeks left before my exams though, I’m going to keep this blog entry brief.
