Do you know of a WEBSITE containing a list of ZERO carb foods?

I need a list of zero - not low - carb foods. I had a hard time with google finding a site that didn't proseletyze about eating carbs (im using the ORIGINAL, not the newer, version of atkins and am doing so under a doctor's supervision) or that didn't include low carb foods on the list. The list my doctor gave me was sort of short and nonspecific.
