Many argue that breakfast is the most important meal of the day. As it turns out, it affects more than a person's health.

A recent study suggests that breakfast choices significantly influence perceived attractiveness, with those consuming refined carbohydrates rated less attractive than those consuming unrefined carbs. Researchers randomly assigned 52 men and 52 women to consume either a 500-calorie breakfast rich in refined or unrefined carbohydrates. 

The refined carb breakfast consisted of industrially milled flour French baguette, jam, fruit juice, and tea or coffee with sugar, while the unrefined carb meal included stoneground wholemeal bread with butter and cheese, along with an orange or apple, and tea or coffee without sugar.

Short- and long-term effects

Blood sugar levels were measured before and after breakfast, and headshots of participants were taken to rate their attractiveness. The researchers found that consumption of refined carbohydrates decreased facial attractiveness for both genders, potentially due to rapid changes in blood sugar and insulin levels affecting skin appearance.

Although the short-term effects were evident, the longer-term implications were more complex and varied by gender and meal type. 

Physiological mechanisms

Refined carbohydrates can cause blood sugar spikes followed by insulin release, leading to hypoglycemia and affecting blood flow and skin appearance. Past studies have supported the findings that fruits and vegetables can enhance attractiveness by increasing skin carotenoids, while high-sugar diets can accelerate skin aging.

What do experts think?

In a report, professor David Perrett from the University of St Andrews, who has studied facial cues for health, suggested that refined carbohydrates might influence peripheral blood flow, impacting skin appearance almost instantly. He noted that healthier skin color, reflecting increased oxygenated blood, contributes to a more attractive appearance. 

Study lead author Dr. Claire Berticat emphasized the importance of limiting refined carbohydrate consumption for both health and aesthetic reasons.
