A new study reveals a statistical connection between the consumption of refined carbohydrates and decreased facial attractiveness, as judged by heterosexual volunteers of the opposite sex. Participants who consumed a high-glycemic breakfast, rich in refined carbohydrates, were rated as less attractive than those who had a low-glycemic meal.

This research, involving 104 French adults, adds to the growing body of evidence suggesting that diet, specifically the intake of refined carbohydrates found in the Western diet, may impact non-medical traits such as attractiveness. The study also observed sex-specific differences in how snack consumption affects attractiveness, highlighting the complex relationship between diet and social perceptions.
