英语翻译还有这句：平时每日吃1斤炒青菜，改用有机生食，1/3斤的量就够了。

Organic vegetables are nutritious and tasty.When eating raw or making soup with them,you only need a very small amount,so they are in fact inexpensive.
If you normally eat 500g of sauteed vegetables,you only need a third of the amount when you switch to using organic vegetables.
英语国家没有斤这个单位所以要说的话只能说500克.如果是美国的话一般用磅比较多,500克大概是一磅.
