When my daughter Alexis was about 5 or 6, she had an obsession with black olives. She liked to put one black olive on each finger and then eat them.
Concerned about the ingredients, contacted the Heinz Company who replied back with a letter with the ingredients list and a coupon for a free jar of olives.
I recently re-looked up the nutritional value of olives and it turns out olives are pretty healthy!
