It’s well established that people with low economic status are the hardest hit by the current obesity pandemic (肥胖症),as well as related health problems such as diabetes. Poor healthcare, stress, unhealthy lifestyles, and a lot of cheap junk food are all thought to play a role. But a new study suggests there’s a subconscious (潜意识)component, too.
When researchers merely led study volunteers to consider themselves low-class, they were more likely to prefer, choose, and eat larger amounts of food, as well as higher-calorie foods. The findings, published in the Proceedings of the National Academy of Sciences, reflect what’s been seen in a variety of animals. Thus, the authors assume that the mental problem may be an evolutionary holdover (遗贸物)intended to improve survival by compensating for a lack of social and material resources. More important for humans, the findings suggest that we may no! be able to deal with obesity by just improving access to healthier foods and promoting exercise.
For the study, psychology researchers at Nanyang Technological University in singapore drafted nearly 500 healthy participants for two experiments. In the first, the team had 101 participants complete a task in which they were shown a ladder with ten steps and told to select which step they were on relative to either a wealthy, well-educated, powerful person or a poor, uneducated, unimportant person. Next, the participants got to pick foods from an imagined buffet. Taking into account things like each participant's normal eating pattern, hunger, and gender, the researchers found that those who ranked their social status lower chose more food and more high-calorie foods than those that ranked themselves as having a higher social status.
In the other experiment, researchers gave 167 participants the same socioeconomic ranking task, then asked them to match high calorie foods (pizza, hamburgers, fried chicken) and low calories foods (vegetables and fruits) with either pleasant or unpleasant descriptors, such as tasty or nasty. Again, those who landed lower on the ladder had a tendency to prefer the high-calorie
“These findings suggest that the thought of low social standing may be critically linked to obesity risk via increased intake of calories,” the authors conclude. As such, the subjective experience of low social standing may be another barrier to improving health.
