Behavioral adaptation in diet maintains nutrient composition in an isolated, confined, and extreme environment in Antarctica.

ABSTRACT:

Background

Comprehensive monitoring of dietary intake in isolated, confined, and extreme (ICE) environments is critical to elucidate physiological adaptations and to mitigate nutrition-related health risks. Although a reduction in energy intake has consistently been reported under ICE conditions, the underlying nutritional determinants remain insufficiently characterized. This study aimed to systematically examine longitudinal changes in dietary intake during a 1-year overwintering mission at Concordia Station, Antarctica.

Methods

Dietary intake data were collected from 34 crewmembers across three overwintering campaigns at Concordia Station, each lasting 12 months with ad libitum food access. Assessments were conducted at five time points (T0: baseline; T1-T3: in-mis
