The radioenzymatic method was used to determine the oxalate contents in common Japanese foods. High concentrations of oxalate were detected in spinach, Perilla frutescens, pepper, sesame, chocolate, and tea. Beer and coffee also contained some oxalate. Fruit and meat were low in oxalate content. Therefore, among the common Japanese foods, the most important foods to be avoided to restrict oxalate intake are chocolate, tea, and spinach.
采用放射酶法测定常见日本食品中的草酸盐含量。在菠菜、紫苏、辣椒、芝麻、巧克力和茶叶中检测到高浓度草酸盐。啤酒和咖啡中也含有一些草酸盐。水果和肉类的草酸盐含量较低。因此，在常见的日本食品中，为限制草酸盐摄入量而应避免的最重要食品是巧克力、茶和菠菜。
