The paper, the press release said, “Illustrate[s] The Need for Nuance in Public Health Guidance Related to Consumption of Sugars: Findings call into question recommendations that imply all sources of fructose-containing sugars carry the same risk.”
The press release notes that “this comprehensive review is timely as the 2025 Dietary Guidelines Advisory Committee currently assesses the latest science to inform updated evidence-based recommendations,” and it quotes the lead author: “There is an opportunity for more food-based guidance around sugars to help ensure Americans don’t inadvertently eat less health-promoting foods containing fructose – especially at a time when most people don’t eat enough of all forms of fruit, which offer significant health benefits.”
Uh oh. This is an easily misinterpreted message.
No surprise.: authors with extensive conflicts of interest.
I’ve written about some of these authors’ conflicts of interest disclosures previously. See, for example. this, this, and this.
Just for fun, I’ll post this particular statement of the conflicted interests at the end of this post.
Basically, these authors do not understand the difference between a conflict of interest (financial ties, which are discretionary) and non-discretionary viewpoints (all researchers have them). In this case, consulting for a sugar company is a conflict; being a vegan or avoiding sugar-sweetened beverages is not.
I contacted John Courtney, the long-time executive director of the ASN. He said this was a leftover from an initiative started ten years ago. Since then, the ASN has decided not to commission papers on controversial topics and this will not happen again.
Good. It shouldn’t. Commissioning papers like these make the ASN look like an arm of the food industry. The ASN should avoid even teh appearance of conflicts of interest as much as it possibly can.
You don’t believe this is a problem? Take a look at this conflict of interest statement. Enjoy!
