Human Food?

Question
I know that dogs should not eat human food but i was wondering what human foods can they eat and which ones can they not?

Answer
I wish I had a link to a good list.  Only in recent years it was found that grapes and raisins can be deadly in even small quantities.  Chocolate has long been a none problem, but fortunately the dosage is quite high, an ounce for every pound of of body weight.  The artificial sweetener Xylitol large found in sugarless gums is terrible.  Onions are bad.  

Green beans and pumpkin are commonly added for bulk in dieting dogs.  Best thing, if it doesn't come out of a dog food bag, don't let the dog eat it.
