A new study published in PLOS ONE has unveiled a rather unexpected side effect of consuming high-glycemic foods: a reduction in facial attractiveness. This work, which shines a spotlight on the link between dietary habits and how we are perceived by others, could have profound implications beyond nutrition and health, delving into the sphere of social interactions and mating preferences.
The research conducted at the University of Montpellier involved 104 French adults, who consumed either a high- or low-glycemic breakfast. Two hours later, their faces were photographed and assessed by heterosexual volunteers of the opposite sex. The results were consistent: individuals who had indulged in a high-glycemic meal were rated as less attractive than those who opted for a low-glycemic alternative.
“We have found that consumption of refined carbohydrates, whether immediate or chronic, affects facial attractiveness,” stated Claire Berticat of the Institute of Evolutionary Science of Montpellier. This correlation was observed across both genders, although the study did note some differences in the effects of afternoon snack between men and women. For men, a higher glycemic load during afternoon snacks was paradoxically associated with increased attractiveness, while for women, the converse was true. This gender disparity suggests that the impact of diet on attractiveness is a multifaceted phenomenon.
“The significance of our findings lies in highlighting the potential influence of dietary choices not only on health but also on nonmedical traits having particular social importance, such as facial attractiveness,” Berticat emphasized. The study meticulously controlled for various factors, including physical activity, BMI, and smoking status, to isolate the effect of diet on perceived attractiveness.
While this study’s insights are remarkable, the authors acknowledge the need for further research, urging for more extensive and diverse investigations. They suggest exploring how these dietary effects might extend to other traits influenced by sex hormones and delve into the complex interplay between diet, biology, and social behavior.
