Every day the food we buy has a profound impact on the lives of animals.

This holiday season, when shopping for groceries or dining out, Americans should appreciate the global impact of what they are eating. Making humane food choices is a simple yet powerful way to make a difference.

Many Americans want to choose humanely but don't know what to look for. To help relieve the confusion, WSPA has ranked humane food labels, such as "cage free," "free range," "grass fed" and "organic."

WSPA recently released the results of its 2009 survey of major US grocery store chains. Find out how your favorite store ranked >> .
