  1. Study participants were Regular Force or Class A Reservists (n = 18). The data presented are energy and nutrient intakes of participants overall and after each of the 8 h experimental treatments [sedentary (21 °C), cold (−10 °C), hot (30 °C) and temperate (21 °C); humidity (~ 30% in the sedentary, hot and temperate treatments and 50% in the cold treatment)]. Energy and nutrient intake data were collected using the measured food intake/food waste method, where all consumed and/or non/partially consumed food and beverage items from the field ration packs were weighed and recorded for each participant. 1Energy and nutrient intake data were examined by Linear Mixed Models with Bonferroni adjustment. 2Strenuous physical activity consisted of infantry activities during the 8 h experimental treatments. Data are presented as the means ± standard deviations (SDs). * P-value is the significance level for differences between the experimental treatments (postsedentary, postcold, posthot and posttemperate). Water intake was not measured during the postexperimental treatment period. RE. Retinol equivalents; DFE. Dietary folate equivalents; NE. Niacin equivalents
