Food carrying an "organic" label may influence people to think that the food is more nutritious compared to "normal" food.
Organic food has been actively debated as whether they are in fact more nutritious.
In the study referenced below, the researchers conducted a double-blind, controlled trial in which 144 subjects at their local mall compared what they thought were "normal" or "organically" produced chocolate sandwich cookies, plain yogurt, and potato chips. All of the products were actually of the organic variety – they were just labeled as being “regular” or “organic.”
The subjects unanimously preferred the "organic" food samples across all group. Perhaps they believed "organic" means more nutritious and/ or tastier. This may mean that eating organic creates some sort of a placebo effect and that they are eating healthier or lower in calories.
