Basically, this was a small randomized trial of blueberry supplementation for heart health funded by the blueberry growers' association Media sources are reporting it as blueberries = good for the heartpic.twitter.com/Aw9IKcoXlF

Now, let's set aside the first 3 points that I mentioned, and just look at what blueberry supplementation did

Here's the table of results. There was no improvement associated with blueberry supplementation in ANY OF THE MEASUREMENTSpic.twitter.com/vbxFHdeWls

The entire basis of the article that I linked to was a small subgroup analysis of less than half the population that found some marginally significant results for one biomarker of insulin controlpic.twitter.com/VzpRNGTont

And we can argue about the importance of this biomarker or the other, but I think it would be better to report that blueberry supplementation has no effect on: - blood sugar - insulin - blood pressure - cholesterol

In other words, this study was entirely negative A better headline: "blueberries useless for health, study finds"

The fact that a totally negative study is being reported as a positive result is emblematic of the power of a catchy press release, because anyone who even glanced at the table of results would realize this was total nonsense

TBH
@nutritionorg I'm a bit surprised that the study was published as is. The discussion made much of the subgroup analysis, but barely even mentioned that there was no improvement on any of the primary or secondary outcomes in the main study itselfShow this thread -
I should say, the positive findings were entirely based on an analysis in statin nonusers who comprised only 50% of the study population, which also breaks randomization ping

I also literally do not understand this COI statement. How can the funders have had no say on the research protocol if the first and second authors are advisers to the funding body?????pic.twitter.com/7lfQJwVDIZ
