摘要
目的参照《中国居民膳食营养素参考摄入量Chinese DRIs》对中国南极考察越冬队员营养摄入基本状况进行现场调查与分析。方法研究对象为中国第24、25次南极考察队越冬队员,共34名,均男性,自由饮食,采用记账法和称重法对考察队员进行膳食调查,然后根据食物成分表计算出每人每日能量和各种营养素摄入量。一年共进行4次。结果禽肉类摄入量等显著超过(中国DRIs)建议摄入量;蔬菜、水果、奶类摄入显著低于(中国DRIs)建议摄入量。能量、蛋白质和脂肪摄入量显著超过(中国DRIs)建议摄入量,维生素A1、B1、B2、C显著低于(中国DRIs)建议摄入量。结论南极考察队员蛋白质脂肪等摄入过高与南极特殊寒冷气候相关。维生素类摄入过低与食品供给条件相关。
