(WHAS11) - The People for the Ethical Treatment of Animals (PETA) has sent a letter to the co-founders of Ben and Jerry's ice cream urging them to replace cow milk in their ice cream with human breast milk.

The letter was sent after reports that a Swiss restaurant will begin buying breast milk and using it in the food they serve. 

PETA says the move to breast milk would lessen dairy cows suffering and be healthier.
