PNAS lifts fructose-appetite study embargo early after realizing media had covered presentation months ago
PNAS is lifting the embargo early on the following paper. All other articles are under the scheduled embargo:
Glucose, fructose, and appetite
Fructose may enhance the reward value of high-calorie food and promote eating, compared with glucose, according to a study. Differences in metabolism of fructose and glucose may lead to differential effects on physiological and behavioral responses to food. To assess the different effects of the two sugars on hunger and food cue responses in the brain, Kathleen A. Page and colleagues conducted fMRI scans on 24 people who had been given drinks sweetened with fructose on one day and glucose on another day.
The journal tells Embargo Watch:
We found out that a substantial portion of the study had been previously presented at a conference and received coverage.
Here’s some of that coverage, from TIME in December.
Something similar happened at PNAS in June of last year, when the journal lifted the embargo early on a study after it learned that the author had published an article about the findings in Nautilus three months earlier.
