Tables for Zinc and Copper Contents of Foods

Here are the USDA pdf's on the zinc contents (http://www.nal.usda.gov/fnic/foodcomp/Data/SR17/wtrank/sr17a309.pdf) and copper contents (http://www.nal.usda.gov/fnic/foodcomp/Data/SR17/wtrank/sr17a312.pdf) of different foods. Those tables give a person a crude sense of things. The table on copper has a pretty major typo at the top. The values, such as 0.111 or whatever, for a hamburger, are 0.111 mg, not ug (micrograms). So 0.060 is 60 micrograms, and 0.111 is 111 micrograms (about a tenth of a milligram), etc. This table on the Wilson's disease site gets the units correct: (http://www.wilsonsdisease.org/copper.html).
