A photographic method of diet evaluation was compared with a weighed record recording method in seventeen subjects. All subjects found the method easy and acceptable though one subject failed to use the method correctly. For the others the two methods gave very similar results, the difference for no nutrient was statistically significant.
在17名受试者中，对一种饮食评估的摄影方法与称重记录法进行了比较。所有受试者都觉得该方法简单且可接受，不过有一名受试者未能正确使用该方法。对于其他受试者而言，两种方法得出的结果非常相似，任何营养素的差异在统计学上均无显著意义。
