The following video is part of our "Motley Fool Conversations" series in which industrials editor/analyst Isaac Pino and consumer goods editor/analyst Austin Smith discuss topics across the investing world.

In today's video, Isaac discusses the recent move by McDonald's to source pork products from suppliers that practice humane treatment of pigs. This announcement could have a "seismic impact" on the industry, according to one animal rights group. That could very well prove true, as we have seen this story unfold in a similar manner through Whole Foods, which sought to change the grocery industry. Similar to Whole Foods, Chipotle, with its dedication to quality ingredients, could be having a ripple effect in the restaurant world.

Companies like Whole Foods are showing how profit margins can be boosted with high-quality, premium products. Meanwhile, other retailers are cutting into Wal-Mart's market share around the world. To learn about a few, we invite you to take a look at a  Motley Fool special free report addressing winners and losers in the retail sector.
