Walmart's Plan to Sell Healthier Foods

Walmart sells more groceries than any other American company, enough to make it a major force in shaping the marketplace. Today, First Lady Michelle Obama appeared with Walmart officials, including Walmart President and CEO Bill Simon, as the company announced a five-year plan to make packaged foods healthier and fruits and vegetables cheaper. The announcement was made at a community center in Washington's Anacostia neighborhood.
