Jeri, I had always heard that about parsley and garlic breath and believed it until recently hearing that it is a myth. I found this info on Wikipedia:

"This well-known phenomenon of "garlic breath" is alleged to be alleviated by eating fresh parsley.[72] The herb is, therefore, included in many garlic recipes, such as [[pistou]], persillade, and the garlic butter spread used in garlic bread. However, since the odour results mainly from digestive processes placing compounds such as AMS (allyl methyl sulfide) in the blood, and AMS is then released through the lungs over the course of many hours, eating parsley provides only a temporary masking."
