如何翻译"谁知盘中餐,粒粒皆辛苦."(英语)

Note that "知" does not necessarily mean "know". It also means "realize". The phrase "谁知" is to call for attention. It may be omitted when translating as a motto. Thus it reads either Each grain in your dish is packed with sweat. Or, Each grain in your dish is a fruit of hard labor. However to translate the entire poem, it is better to include "谁知" for coherence. Thus it will read: How many of you realize that each grain in your dish is a fruit of arduous labor?
