Retail giant, Wal-Mart Stores Inc. made a huge announcement earlier this week stating their plans to reformulate thousands of their food products to meet healthier standards.Specifically, by 2015, Wal-Mart aims to reduce sodium by 25% and sugar by 10% in their Great Value brand as well as national brands. And in the meantime, they are working on removing partially hydrogenated oils and trans fats from food products.First Lady Michelle Obama’s fight against childhood obesity served as a catalyst for this bold move from Wal-Mart and prompted a collaboration between the two to see the efforts put into place.By working with suppliers and farmers to lower costs (like on transporation), Wal-Mart intends to pass these savings onto their consumers to offer more fresh foods at lower prices. The objective is to save $1 billion a year to consumers for these healthy foods and promote healthy eating overall.
