大熊猫作为“素食者”，平日主要进食竹子为生。不过，近日有来自中国及澳洲的科学团体研究发现，从熊猫的消化吸收营养结构上看，它们应为肉食动物，而非大家过往理解的草食动物。

有关研究刊于美国科学杂志《当代生物学》(Current Biology)上，指熊猫日常摄入的蛋白质和碳水化合物的数量更接近“超级肉食动物”，而吸收的能量约半数来自蛋白质，此与狼和野生猫科动物相近。

研究团体发现，属肉食类及熊科类的熊猫，其草食习惯高度受它们特殊的生物进化方式影响，故此熊猫们有适应纤维性饮食的头骨、下颌肌肉组织和齿型等。此外，它们用来抓竹子的“假拇指”，及失去了辨别“鲜味”的能力，均与这种演化有关，但它们体内仍保留有类似于肉食动物的消化道、消化酶和肠道微生物。

研究结果显示，熊猫的进化程度比此前设想的要低，甚至更为“表面”，而其消化系统变化不大，此解释为何它们兼具草食及肉食动物的特质。
