Lasting impressions: Psychologists discover what influences our food choices
Society for Personality and Social Psychology

As New Year's resolutions come and go, one area many people focus on is their health and weight. With Americans tipping the scales more than ever, social and personality psychologists are at the forefront of understanding the psychological motivations for healthy food choices and consumption patterns.

First impressions of food: Growing up poor's long-term impact on eating patterns

Studying the psychology of food choice, Texas Christian University's Dr. Sarah Hill's research revealed that childhood socioeconomic status may influence people's food choices as adults. "Our research finds that growing up poor promotes eating in the absence of hunger in adulthood, regardless of one's adult socioeconomic status."

According to their findings, this means that a person's developmental history may play a key role in their relationship with food and weight management, rendering those from lower socioeconomic status (SES) environments more vulnerable to unhealthy weight gain.

"Healthy" food: Serving order and labels influence healthy eating

Dr. Mann's investigations showed that in elementary school cafeterias, serving broccoli or red peppers first led over four times as many students to eat the vegetable than on a normal day in which the vegetable was served alongside other food offerings. The researchers followed up the experiment in a lab setting, providing various types of snacks, and found similar results.

Mann's lab also found adults responds better to healthy symbols rather than the word "healthy."

In one field study with about 400 adults; 65% took an apple (instead of candy) if the healthy heart symbol was on the sign, but only 45% took an apple if the word "healthy" was on the sign. In another field study of about 300 adults, 20% took carrots (instead of chips) if a sign said "healthy," and 30% took carrots if sign had healthy heart symbol on it.

According to Dr. Mann, "The word 'healthy' seems to turn people off, particularly when it appears on foods that are obviously healthy. The subtle health message, such as the healthy heart symbol, seemed to be more effective at leading people to choose a healthy option."
