This study shows that the energy intake of the Dutch Light Armoured Brigade was consistently below the MDRI values in the field, on base and at home. To help address this energy deficit, increasing the consumption of fiber-rich carbohydrate sources may be an effective strategy. However, in the field setting, MDRI-based energy expenditure estimates may not have fully reflected the actual activity demands. Therefore, more accurate assessment of energy expenditure and better alignment between ration provision and expected activity demands may help reduce unnecessary carrying load, food waste, and logistical burden, while ensuring sufficient energy availability for military units.
INTRODUCTION: Adequate nutrition is essential for optimal health, performance and operational readiness of military personnel. Inadequate nutrition has been associated with reduced health and performance, and an increased risk of injuries and dropouts. Despite its importance, limited data are available on the dietary intake of Dutch military personnel. This study aims to assess the energy and nutrient intake of Dutch soldiers in 3 settings: in the field, on base and at home.
MATERIALS AND METHODS: Included in the study were 72 soldiers from the Dutch Light Armoured Brigade. Dietary intake during field deployment was assessed using a food intake/waste collection-based method, whereas on base and at home, participants recorded their dietary intake using online food diaries. Dietary intake data were compared against the Military Dietary Reference Intakes (MDRIs). Energy expenditure on base and at home was estimated using online questionnaires and compared against reported energy intake.
RESULTS: Fiber intake across all 3 settings and carbohydrate intake on base and at home were below the MDRIs. In contrast, protein intake across all settings, as well as carbohydrate intake in the field, met the MDRIs. Intake of total fat, saturated fat and sodium exceeded the MDRIs in all settings. Energy intake was below the MDRIs in all settings, but comparable to energy expenditure on base and at home.
CONCLUSIONS: This study shows that the energy intake of the Dutch Light Armoured Brigade was consistently below the MDRI values in the field, on base and at home. To help address this energy deficit, increasing the consumption of fiber-rich carbohydrate sources may be an effective strategy. However, in the field setting, MDRI-based energy expenditure estimates may not have fully reflected the actual activity demands. Therefore, more accurate assessment of energy expenditure and better alignment between ration provision and expected activity demands may help reduce unnecessary carrying load, food waste, and logistical burden, while ensuring sufficient energy availability for military units.
