Does Exposure to Food Advertisements Influence Dietary Intake?


This research highlights the diet sensory perceptual relationship (DSPR) as a core mechanism within the broader diet mental health relationship and a foundational component of nutritional psychology. The DSPR explains how sensory and perceptual experiences influence dietary choices and eating behavior.

Zimmerman and Shimoga (2014) investigated how exposure to food advertising affects food selection, particularly under varying levels of cognitive demand. Participants were assigned to one of four conditions combining food or non food advertisements with either cognitively demanding or non demanding tasks. Researchers measured both the number of unhealthy snacks selected and total caloric intake.

Results showed that participants exposed to food advertisements selected 28 percent more unhealthy snacks than those exposed to non food advertising, resulting in an average increase of 65 kilocalories. Importantly, the effect of advertising was strongly moderated by cognitive load. Among participants completing cognitively demanding tasks, those exposed to food advertisements consumed 43 percent more unhealthy snacks and an additional 94 kilocalories compared to those viewing non food advertisements. No significant differences were observed in participants performing less cognitively demanding tasks.

These findings demonstrate that food advertising significantly influences dietary intake, particularly when individuals are mentally taxed and have reduced cognitive resources for self regulation. This effect has been observed across both adult and child populations through television and internet advertising.

The study reinforces the importance of understanding how environmental sensory cues interact with psychological processes to shape eating behavior. The Center forNutritional Psychology provides the conceptual framework needed to integrate these findings and better understand how sensory exposure, cognition, and diet interact to influence mental and physical health.

This summary is based on the article “Does Exposure to Food Advertisements Influence Dietary Intake? by the Center for nutritional psychology.

 Mental Health Professionals Report Poor Literacy for Nutritional Medicine: International Survey Summary :  A 2021 international online survey by Mörkl et al. assessed nutritional literacy among mental health professionals (MHPs) across 52 countries. The sample included psychologists, psychiatrists, psychotherapists, and professionals in training, with most participants based in Europe and additional representation from Asia, North America, Oceania, South America, and Africa. The findings revealed a substantial gap between interest in nutritional psychiatry and formal training.

Despite this, many were already integrating nutritional strategies into clinical practice: 58.6 percent recommended supplements and 43.8 percent recommended dietary...
