CAFE experiments show <i>Drosophila melanogaster</i> actively consume erythritol over time.

<p>Upper graph shows prandial behavior of 10 individually housed flies fed 5% erythritol (red colums) and 10 individually housed flies fed 5% sucrose (blue columns) over a 6 hour period. Average intake per fly per hour is graphed for each treatment and is separated by sex. Lower graph shows prandial behavior of 10 indivually housed flies when presented with a choice between 5% erythritol (red colums) and 5% sucrose (blue columns). Average intake per fly per hour is graphed for each treatment and is separated by sex. Note the significant increase in erythritol intake compared to sucrose intake for both sexes.
