Naturally green, irrationally lean: How background scenery affects calorie judgments

Area of Science:

• Consumer Psychology
• Environmental Psychology
• Food Science

Background:

• Previous research indicates that adding vegetables to meals creates a "health halo," reducing perceived calorie content.
• This study explores if environmental stimuli suggesting naturalness can evoke similar health halo effects.

Purpose of the Study:

• To investigate if natural background scenery, compared to urban scenery, lowers perceived calorie content of meals.
• To examine if the perceived healthiness of food moderates this effect.

Main Methods:

• A mixed-design experiment involving 200 participants.
• Participants estimated calorie content and rated healthiness of 18 meals presented against natural or urban backgrounds.

Main Results:

• No main effect of background scenery on overall calorie perception was found.
• A negative correlation existed between inferred food healthiness and estimated calorie content.
• A significant interaction revealed that unhealthy foods were rated lower in calories against natural backgrounds than urban ones.

Conclusions:

• Perceived food healthiness plays a crucial moderating role in how environmental cues influence calorie judgments.
• Natural environments may bias calorie estimations, particularly for less healthy food options.
