Organic labels trick dieters into eating more.

So much for my organic, vitamin-fortified hotdog-shoved-in-a-Twinkie idea. From LiveScience:

The "organic" label skews people's perceptions about food in ways that might promote obesity, a new study finds.

The results show people sometimes assume organic foods are lower in calories and so it's OK to indulge in organic cookies more often than regular ones. Exercise was also deemed less necessary after eating organic desserts.

The findings are in line with previous work showing food labels can spur misperceptions. For instance, labeling a food as "low fat" can lead people to infer that it also has fewer calories, and foods marked as having "low cholesterol" can be judged as having less fat. Also, there is a strong tendency for Americans to associate the concept of "organic" with healthiness, the researchers say.
